Detailed Product Description: | Definition and uses hydraulic motors used to refer to the output rotary motion of the hydraulic pump can provide energy into mechanical energy conversion device.? Hydraulic motor, also known as motor oil, mainly used in injection molding machinery, ships, etc. from Yang . ? High-speed motor? Geared motor with small size, light weight, simple structure, technology is good, is not sensitive to oil pollution, the impact resistance and inertia is small. Disadvantages greater torque ripple, low efficiency, starting torque is small (only 60% of the rated torque - 70%) and low-speed stability and poor. ? Vane motor vane motor? Vane motors and other types of motor compared with a compact, small size silhouette, low noise, long life and other advantages of small piston motor inertia ratio column, but worse than the anti-pollution gear motors and speed not too high, generally 200r/min? following work. Vane motor due to leakage is large, it is unstable or low speed when the load changes. ? Motor type radial piston motors? Axial piston motors? Bent axis piston motor? Swash plate piston motor? Low speed hydraulic motors? Radial piston motors? Rod hydraulic motor? Simple structure, reliable, full specifications, low prices. The disadvantage is that a larger volume and weight, the larger the torque ripple?. ? No link hydraulic motor? Swing cylinder type hydraulic motor? Roller hydraulic motor???? Axial piston motors? Double swash plate piston motor? Axial piston motors ball? Vane motor? Cycloid motor the late 1850s, the initial low speed high torque hydraulic motor is composed of a pump rotor components evolved, this unit consists of a ring gear and a gear or rotor with matching components. Fixed ring gear and the housing can be connected together into the oil from the oil port push the rotor revolves around a central point. This slow rotation of the rotor drive shaft splined output becomes cycloid hydraulic motor. After this initial orbital motors come out, after decades of evolution, the concept of alternative motor began to form. This motor is installed in the built-in ring roller, motor roller having to provide a high starting torque and running rollers reduce friction, thereby increasing the efficiency even at low rotational speed of the output shaft is can produce stable output. By changing the direction of flow of the input and output of the motor commutation quickly and produce, such as the value of torque in both directions. Each series has a variety of motor displacement choose who to meet a variety of speed and torque requirements. ? Editing features and characteristics of the hydraulic motor according to the classification of segments from the viewpoint of energy conversion, the hydraulic pump and the hydraulic motor is a reversible hydraulic components work input to any one of the working liquid pump, the hydraulic motor can work so that it becomes condition; Conversely, when the spindle is rotated by a hydraulic motor driven external torque, the pump can be changed conditions. Because they have the same basic structural elements - but the volume can be a closed cycle and corresponding changes with oil bodies. ? However, due to the different hydraulic motors and pumps working conditions, performance requirements are not the same, so that between the type with hydraulic motors and pumps, there are still many differences. First hydraulic motor should be able to, reverse, thus requiring its internal structure symmetry; speed range of hydraulic motors require large enough, especially to its lowest steady speed have certain requirements. Therefore, it is usually by rolling or hydrostatic slide bearings; followed by a hydraulic motor input pressure due to work in the oil condition, and thus do not need to have the ability to self-absorption, but requires some initial tightness in order to provide the necessary starting torque. Because of these differences, so that the hydraulic motor and pump similar in structure, but not reversible work. ? Classified according to their structure type hydraulic motor can be divided into sub-gear, vane, piston, and other types. The rated speed of the hydraulic motor is divided into two major categories of high and low speed. Higher than the rated speed 500r/min belongs to the high-speed hydraulic motors, rated speed 500r/min below belong to the low-speed hydraulic motors. The basic types of high-speed hydraulic motor gear, screw, vane? Axial piston and so on. Their main feature is a high speed, small moment of inertia for easy starting and braking, regulating high (speed and commutation) sensitivity. High-speed hydraulic motor output torque is usually not so called high speed low torque hydraulic motors. The basic types of low-speed hydraulic motors are radial piston type, in addition to the axial piston, vane and gear also has low structural type, the main features of low-displacement hydraulic motor is large, bulky low speed (sometimes even turn up a few tenths of revolutions per minute), it can be directly connected with the work of agencies; does not require deceleration device, so that the transmission mechanism greatly simplified, low-speed hydraulic motor output torque is usually large, it is also known as the low speed and high torque a hydraulic motor. ? Edit this paragraph hydraulic motor main structure and principle of hydraulic vane motor oil due to the pressure effect, the uneven rotor to generate torque. The vane-type hydraulic motor and the output torque of the hydraulic motor and the displacement of the hydraulic motor and out of the pressure differential between the ports on which the input speed of the hydraulic motor to determine the size of the flow. As the hydraulic motor can generally require reversing, so vane-type hydraulic motor to radial placement. In order to make the blade root is always through the oil pressure in the back pressure chamber Walter blade root path should be one-way valve, hydraulic motor to ensure that the blade pressure oil Walter after normal start, you must make the top of the blade and in close contact with the inner surface of the stator in order to ensure a good seal, should be set so the preload of the spring blade root. ? Vane type hydraulic motor small, small moment of inertia, sensitive, suitable for high frequency commutation occasions; but the larger the amount of leakage, low work instability. So vane hydraulic motors are generally used for high speed and torque requirements of small and motion sensitive occasions. ? Radial piston hydraulic motor radial piston hydraulic motor works, when the bottom pressure oil through the window fixed with 4 oil into the cylinder axis of the plunger, the plunger outwardly, tightly top live stator inner wall, the stator and the cylinder there is an eccentricity. In the contact point between the plunger and the stator, the stator is a reaction force of the plunger?. Force can be decomposed into?, And? Two components. When the fluid pressure acting at the bottom of the plunger is p, the diameter of the piston d, the angle between the force and the? X, the force generates a torque on the cylinder, so the cylinder is rotated. Output torque and rotational speed of the cylinder and then out through the shaft end face of the connection. ? A plunger above analysis the torque generated due to the pressure chamber acts on the plunger several torque generated on the plunger of the cylinder so that both rotate and output torque. Radial piston hydraulic motors are used for low-speed large??? Case the motor torque curve. ? 1. Single acting rod-type radial piston motors? Figure 4-6, rod motor, shaft with a hydraulic motor flow chart, the Pentagon radial motor assembly animation shows the single acting rod-type radial piston motors Work schematics, its appearance was pointed star shape. The motor housing 1 by the crankshaft 6, with a flow axis 5, link 3, the plunger 2, and 4 other parts eccentric. ? Advantages: simple structure, reliable work. ? Disadvantages: bulky, heavy, pulsating turn twist, poor low-speed stability. ? 2 much. Effect curve piston motor? Shaft of the motor by the composition of an assignment, 2 cylinder, piston 3, beam 4, wheel 5, the stator 6 and the output shaft 7 and so on. This motor displacement than single stroke motors increased 1 times. Corresponds with the plunger 21. Due to the increased number of equivalents of the plunger,? Working at the same pressure, the output torque increase, the torque ripple rate decreases. Such a motor may be made more rows plunger, several more, further increase the output torque, the torque ripple rate is further reduced. Therefore, this displacement of the motor can be made large and stable operation at a low speed can become lower. Since the motors require bi-directional rotation, so the blades radially arranged slots. ? 3. Plunger speed hydraulic motors? Plunger speed hydraulic motors are generally axial type. ? Axial piston valve type axial piston pump in addition to the flow, the other forms of principle, can be used as a hydraulic motor, the axial piston pumps and axial piston motor is reversible. Axial piston motor working principle, oil pan and the swash plate is fixed, and the cylinder is connected to the motor shaft rotate together. When the pressure oil through the oil pan with a window into the plunger bore of the cylinder, the piston action of the oil under pressure extended, close to the swash plate of a swash plate plunger method to generate a reaction force p, this force can be decomposed into and axial component and vertical component Q. The hydraulic pressure on the plunger equilibrium Q, and Q is the center of the cylinder of the plunger to produce a torque to drive the motor shaft is rotated counterclockwise. Instantaneous total axial piston motor torque generated is pulsating. If the oil pressure input to change the direction of the motor, the motor shaft is rotated in the clockwise direction. A swash plate change, that change in displacement, not only affects the torque of the motor, but also affected its speed and direction. The swash plate angle the greater torque is generated, the lower the speed. ? Hydraulic gear motor gear motor reversing the structure in order to meet the requirements, and out of ports equal, symmetrical, with separate oil port leakage leaking oil bearing portion of the outer shell leads; in order to reduce friction torque start using rolling bearings; In order to reduce torque ripple gear teeth hydraulic motor pump to be more than the number of teeth. ? Gear hydraulic motor from a dry seal is poor, low capacity leased efficiency, enter the oil pressure is not too high, can not produce a greater torque. And the instantaneous speed and torque vary as the position of the engagement point is changed, so the gear-speed hydraulic motor is suitable only for low torque applications. Generally dry construction machinery, agricultural machinery and uniformity of torque less demanding on machinery and equipment. ? High-speed hydraulic motor rated speed of the motor are higher than 500r/min speed motor. The basic form of high-speed motor gear, vane and axial piston. They are mainly characterized by high speed, small moment of inertia, easy starting, braking, speed and commutation. ? 500r/min low speed hydraulic motor speed is lower than the low-speed hydraulic motors are hydraulic motor. Its basic form is a radial piston. The main features of the low-speed hydraulic motors are: large displacement, large volume, low speed, can be directly connected with the work of agencies, no deceleration device, so that the transmission mechanism is greatly simplified, low-speed hydraulic motor output torque is large, up to several thousand to tens of thousands of Nm, so-called low speed high torque hydraulic motors. ? Edit hydraulic motor to calculate the main parameters of this paragraph the main parameters of a hydraulic motor. Work stress and pressure rated working pressure:? Actual pressure input motor oil, and its size depends on the motor load. ? Motor inlet pressure and outlet pressure difference is called differential motor. ? Rated pressure: according to the test standards, so that the maximum pressure motor continuously working properly. ? 2. ? Displacement and flow displacement: VM (m / rad) Excluding traffic flow theory, said leakage flow qMt, considering the leakage flow is the actual flow qM???. ? 3. ? Volumetric efficiency and speed volumetric efficiency ηMv: the ratio of the actual input traffic flow and theoretical input, 4?. ? Torque and losses in mechanical efficiency, excluding the motor, the output power is equal to the actual power input torque T:.? Due to mechanical losses and the actual motor torque loss generated ΔT, than the theoretical torque Tt so small, that the mechanical motor Efficiency ηMm: The actual motor output torque is equal to the theoretical output torque than 5.?. ? The power and overall efficiency of the motor actual input power is pqM, the actual output power of Tω motor overall efficiency ηM:.?? Actual output power and the actual input power ratio [1] hydraulic motor circuit hydraulic motor has two loops:? Ie the series circuit of the hydraulic motor and the hydraulic motor brake circuit, and these two circuits and then the next layer can be classified hydraulic motors in series, one circuit:? three hydraulic motors in series to each other, with an opening stop valve and its control steering. The flow through the three motors are substantially equal, the same, the motor speed is substantially the same in its displacement pumps require a higher supply pressure, the flow rate of the pump can be small, generally the case for high-speed light-load . ? Series circuit of two hydraulic motors: This circuit controls a motor of each valve, the operation of the motor may be used alone, or may be operated simultaneously, and each of the steering motor is also arbitrary. Hydraulic oil pressure to working pressure of each motor and is suitable for high-speed low torque applications. ? Parallel circuit of hydraulic motors: two hydraulic motors through their respective control valve and control valve, which can operate with a single operation, respectively, for speed, and the speed can be basically unchanged. But with the throttle, the power loss is large, the two motors have their work pressure, its speed depends on the flow of their passes. ? Parallel circuit of two hydraulic motors: a shaft rigidly coupled together, the two hydraulic motors, when the valve (3) in the left position, the motor 1 with the motor 2 can be idle, only the output torque of the motor 1. If an output torque of the motor can not meet the load requirements, the valve 3 placed in the right position, although this time the torque increase, but the speed should be reduced accordingly. ? Hydraulic motor series and parallel circuits: a charging solenoid valve, the hydraulic motor 2 and 3 are connected in series, a solenoid valve is off, the motor 2 and 3 in parallel. When the two motors in series by the same traffic, higher speed than in parallel, while the two motors working in parallel the same pressure, but a lower speed. ? 151F0685 OMS 160 HYDRAULIC MOTOR? 151F0687 OMS 315 HYDRAULIC MOTOR? 151F0693 OMS 200 HYDRAULIC MOTOR? 151F0714 OMS 100 HYDRAULIC MOTOR? 151F0715 OMS 80 HYDRAULIC MOTOR? 151F0716 OMS 125 HYDRAULIC MOTOR? 151F0738 OMS 160 HYDRAULIC MOTOR? 151F0743 OMS 80? 151F0746 OMS 160 HYDRAULIC MOTOR? 151F2201 OMS 100 HYDRAULIC MOTOR? 151F2202 OMS 125 HYDRAULIC MOTOR? 151F2205 OMS 250 HYDRAULIC MOTOR? 151F2206 OMS 315 HYDRAULIC MOTOR? 151F2211 OMS 200 HYDRAULIC MOTOR? 151F2262 OMS 400 HYDRAULIC MOTOR? 151F2264 OMS 400 HYDRAULIC MOTOR? 151F2291 OMS 160 HYDRAULIC MOTOR ? 151F2300 OMS 80 HYDRAULIC MOTOR? 151F2301 OMS 100 HYDRAULIC MOTOR? 151F2304 OMS 200 HYDRAULIC MOTOR? 151F2310 OMS 125 HYDRAULIC MOTOR? 151F2320 OMS 200 HYDRAULIC MOTOR? 151F2321 OMS 250 HYDRAULIC MOTOR? 151F2322 OMS 315 HYDRAULIC MOTOR? 151F2323 OMS 400 HYDRAULIC MOTOR? 151F2353 OMS 160 HYDRAULIC MOTOR? 151F2354 OMS 200 HYDRAULIC MOTOR? 151F2356 OMS 315 HYDRAULIC MOTOR? 151F2361 OMS 125 HYDRAULIC MOTOR? 151F2370 OMS 125 HYDRAULIC MOTOR? 151F2371 OMS 160 HYDRAULIC MOTOR? 151F2372 OMS 200 MAGNETO HYDRAULIC MOTOR? 151F2374 OMS 315 HYDRAULIC MOTOR? 151F2375 OMS 400 HYDRAULIC MOTOR? 151F2397 OMS 125 HYDRAULIC MOTOR? 151F2398 OMS 160 HYDRAULIC MOTOR? 151F2399 OMS 200 HYDRAULIC MOTOR? 151F2400 OMS 250 HYDRAULIC MOTOR? 151F2402 OMS 400 HYDRAULIC MOTOR? 151F2413 OMS 80 HYDRAULIC MOTOR? 151F3020 OMS 80 EM HYDRAULIC MOTOR? 151F3021 OMS 100 EM HYDRAULIC MOTOR? 151F3022 OMS 125 EM HYDRAULIC MOTOR? 151F3023 OMS 160 EM HYDRAULIC MOTOR? 151F3024 OMS 200 EM HYDRAULIC MOTOR? 151F3025 OMS 250 EM HYDRAULIC MOTOR? 151F3026 OMS 315 EM HYDRAULIC MOTOR? 151F3027 OMS 400 EM HYDRAULIC MOTOR? 151F3044 OMS 80 EM HYDRAULIC MOTOR? 151F3045 OMS 160 EM? 151F3060 OMS 125 EM HYDRAULIC MOTOR? 151F3061 OMS 160 EM HYDRAULIC MOTOR? 151F3063 OMS 250 EM HYDRAULIC MOTOR? 151F3125 OMS 125 HYDRAULIC MOTOR? 151F3134 OMS 200 HYDRAULIC MOTOR? 151F5100 OMS 80 HYDRAULIC MOTOR? 151F5101 OMS 100 HYDRAULIC MOTOR? 151F5102 OMS 125 HYDRAULIC MOTOR? 151-7049 OMP 400 HYDRAULIV MOTOR? 151-7061 OMP 50 HYDRAULIC MOTOR? 151-7062 OMP 80 HYDRAULIC MOTOR? 151-7063 OMP 100 HYDRAULIC MOTOR? 151-7065 OMP 160 HYDRAULIC MOTOR? 151 ? -7066 OMP 200 HYDRAULIC MOTOR 151-7068 OMP 315 HYDRAULIC MOTOR 151-7069 OMP 400 HYDRAULIC MOTOR 151-7080 OMP 25 HYDRAULIC MOTOR 151-7209 OMR 315 NF HYDRAULIC MOTOR 151-7245 OMR 200 HYDRAULIC MOTOR 151????? - 7264 OMR 160 HYDRAULIC MOTOR? 151-7266 OMR 250 HYDRAULIC MOTOR? 151-7267 OMR 315 HYDRAULIC MOTOR? 151-7275 OMR 200 HYDRAULIC MOTOR? 151-7284 OMRS 160 HYDRAULIC MOTOR? 151-7289 OMR 50 HYDRAULIC MOTOR? |
