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 customized Cycloidal motor of overhead crane 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. Zhenjiang Price Unexpected failure of hydraulic motor will greatly reduce production efficiency.

The hydraulic motor has two circuits: the hydraulic motor series circuit and the hydraulic motor braking circuit. These two circuits can be classified into the next category. One of the series circuits of hydraulic motors: three hydraulic motors are connected in series with each other, and a reversing valve is used to control the start stop and steering. The flow through the three motors is basically the same. When the displacement is the same, the speed of each motor is basically the same. The oil supply pressure of the hydraulic pump Zhenjiang Price High, small pump flow, generally used for light load and high speed. Serial circuit II of hydraulic motor: each reversing valve in this circuit controls one motor, each motor can work independently or simultaneously, and the rotation direction of each motor is also customized Cycloidal motor of overhead crane optional. The oil supply pressure of the hydraulic pump is the sum of the working pressure difference of each motor, which is applicable to the condition of high speed and small torque.

Hydraulic motors are divided into high-speed hydraulic motors and low-speed hydraulic motors. They are widely used in many aspects. The manufacturer told us that they are convenient to use and suitable for high-speed hydraulic motors. First, its adjustment sensitivity is very high: due to special structural design and composition, high-speed hydraulic motors generally have high adjustment sensitivity, especially in speed adjustment Cycloidal motor of overhead crane Price This is especially true during the integration and commutation. In this way, the user can make the motor itself respond sensitively and enter the corresponding working state through simple operation when using the motor. Second, get up Zhenjiang Price It is very convenient to move and brake: because the high-speed hydraulic motor has the characteristics of high speed and small moment of inertia, it can easily enter the corresponding state when starting and braking in application. This convenience is an important part of its convenient application. High speed hydraulic motor has many advantages, which brings us great convenience.

As a hydraulic equipment, hydraulic motor has been widely used in many factories. Generally, we should master the assembly skills of the hydraulic motor: the hydraulic system should customized Cycloidal motor of overhead crane Correct machining and assembly. The mounting surface of the hydraulic valve on the oil block should be straight, and the sealing surface of the sealing groove should be finished to avoid radial scratches. The preload of the connection between the hydraulic valve and the oil circuit block and the connection between the oil circuit blocks shall be sufficient to prevent surface separation. The hydraulic equipment shall be inspected according to relevant standards before assembly Cycloidal motor of overhead crane Price Check the pressure leakage of system components. If problems are found, corresponding measures shall be taken. If the problem is serious, it should be replaced. Accurately formulate the assembly process documents of hydraulic equipment, configure necessary assembly tools, and strictly follow the assembly process. Keep the hydraulic components, accessories, sealing parts and pipe fittings clean to prevent contamination, and check the integrity of the sealing surface and connecting threads. The hydraulic connector should not be tightened too tightly, otherwise some parts will be severely deformed or even broken, causing leakage. Avoid damaging sealing parts during assembly.

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 customized Cycloidal motor of overhead crane 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 motor of overhead crane 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).

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 motor of overhead crane 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 Zhenjiang 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.
