Generally, rolling bearing or hydrostatic sliding bearing, hydraulic want to buy Cycloidal hydraulic motor brake Since the pressure motor works under the condition of input pressure oil, it does not need to have self-priming capacity, but it needs to have a certain initial air tightness to provide the necessary starting torque. The existence of these differences makes the structure of the hydraulic motor and the hydraulic pump relatively close, but they cannot work reversibly. The classification of hydraulic motors can be divided into gear type, impeller type, plunger type and other types according to the structure type. According to the rated speed of the hydraulic motor, it can be divided into high speed and low speed. The rated speed exceeds 500r/min Qinghai Cycloidal hydraulic motor brake High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.

The hydraulic motor manufacturer explains to you the reasons for the poor performance of the hydraulic motor: 1. First of all, according to the analysis of the causes of the wear of the port plate, the main reasons for the weakness of the hydraulic motor are: because the port plate is worn, the oil inlet channel and the oil return channel are connected at the port plate, part of the high-pressure oil leaks, the oil pressure flowing through the stator and rotor pair decreases, and the flow decreases, Eventually, the output speed and torque of the motor will decrease. 2. Due to the wear of the valve plate, its relative position in the valve body has changed Cycloidal hydraulic motor brake Price The preload and adhesion of the spring on the valve body between the valve plates will be reduced, which will intensify the leakage of hydraulic oil and lead to the decline of the performance of the hydraulic motor. 3. With the increase of hydraulic oil temperature, its comprehensive performance declines, driving the cycloidal rotor to rotate Qinghai Price The ability to move is further reduced. Upon inspection, there is no obvious wear on the joint surface of the stator and rotor pair and the bearing seat and valve disc matched with both sides of the stator and rotor pair. The movement is normal without jamming, which will not cause performance degradation.

As the power source and actuator of the hydraulic system, the performance of the hydraulic motor has a great impact on the performance of the entire hydraulic system. Therefore, the importance of studying the hydraulic motor performance test system is want to buy Cycloidal hydraulic motor brake It is very important that the rise and application of hydraulic testing technology based on virtual instrument has opened up a broad prospect for the performance testing of hydraulic motors. Hydraulic motors are widely used in machine tools, metallurgy, engineering machinery, plastic machinery, agricultural machinery, mining machinery, marine machinery and many other important fields. The performance of the hydraulic motor has a decisive impact on the whole system, and will directly affect the stability of the system. At the same time, the performance of the hydraulic motor will have an impact on the life of the system components and the production efficiency of the system. Qinghai Price Unexpected failure of hydraulic motor will greatly reduce production efficiency.

The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action want to buy Cycloidal hydraulic motor brake Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used Cycloidal hydraulic motor brake Price In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action of the motor).

BM cycloidal hydraulic motor is a small low-speed high torque hydraulic motor with single axis flow distribution and fixed rotor set. Its advantages are as follows: 1. It is small in size and light in weight, and its overall size is much smaller than other types of hydraulic motors with the same torque. 2. Wide speed range, stepless speed regulation, minimum stable speed up to 15 rpm, convenient installation and layout, low investment cost. 3. It can be used in series or parallel in the hydraulic system. 4. The moment of inertia is small, and it is easy to start under load. It can rotate in both forward and reverse directions, and it does not need to stop when reversing. BM cycloidal motor is widely used in agriculture, fishery, light industry Cycloidal hydraulic motor brake Price The slewing mechanism of hoisting and transportation, mining, construction machinery and other machinery. Examples of BM cycloidal hydraulic motor used abroad; 1) Agricultural use: various combine harvesters, seeders, rotary tillers, lawn mowers, sprayers, feed mixers, ground drills. 2) Fishery use: net lifter. want to buy Cycloidal hydraulic motor brake 3) Light industry: commercial winding machines, textile machines, printing machines, washing machines. 4) For construction industry: road roller, cement mixer, sweeper.

In the middle opening system, the main reversing valve of the middle opening system is in the middle position, through which the hydraulic pump is unloaded, and the liquid returns to the oil tank under low pressure. This kind of system generally uses constant displacement pump as oil source; When the reversing valve is in the middle position, the energy transmission starts with a low value that is basically zero, and the energy rises after changing, so that the pressure liquid enters want to buy Cycloidal hydraulic motor brake The actuator acts on the load; When the reversing valve is in the middle position, the internal leakage is very small. Generally, when the same function is achieved, the energy consumption of the intermediate open circuit is smaller. in Qinghai want to buy Open system is mostly used for working conditions requiring intermittent movement or supporting load, such as prime movers that do not want to start and stop frequently. The system has high efficiency, and needs to use makeup oil pump and flushing valve for oil makeup and heat exchange.
