To reduce Hydraulic transmission In system application Hydraulic motor The pressure energy loss of the system should first be gradually from the inside to reduce the output power loss in addition to reducing the internal pressure loss of the system software. To solve this problem, the pressure loss of the internal flow passage of the components can be improved, and the integrated control circuit and forging flow passage are selected. In addition, the loss of throttle valve of system software must be reduced or eliminated, and the total overflow flow that is not necessary for safety must be reduced as far as possible to prevent the use of throttle valve system software to adjust the total flow and pressure. In the application of raw materials, raw materials manufactured by negative pressure technology and new rubber seals can be selected, so that friction losses can be reasonably reduced. Maintenance is necessary in application. Maintain the hydraulic motor immediately to prevent environmental pollution from harming the service life and stability of the motor. It is necessary to develop a new pollution monitoring method, carry out automatic measurement of environmental pollution, adjust it immediately, and do not allow it to fall behind, so as to prevent losses caused by not solving it immediately. In order to reduce pressure energy loss of hydraulic motor, the manufacturer and customers must work together to avoid pressure energy loss to a large extent. The cleaning of the natural hydraulic motor is also important. The hydraulic motor generally needs to be cleaned before it is announced to be delivered for use. The purpose of cleaning is to eliminate the air pollutants, metal material scraps, chemical fiber chemicals, iron cores, etc. left in Madan. In the first two hours of work, even if Madan is not completely destroyed, it will cause a series of common failures. Therefore, the motor oil passage should be cleaned according to the following procedure: 1. Clean the car oil tank with an easily drying organic solvent, and then remove the organic solvent precipitate with the considered gas. 2. Clean all pipes of the motor. In some cases, pipes and connectors must be pre soaked. 3. Install a filter on the pipeline to maintain the oil pipeline and pressure pipeline provided by the valve. 4. Use cleaning plate instead of high-precision valve, such as electro-hydraulic servo valve. 5. Check whether the specifications of all pipelines are suitable and the connection is proper. To ensure the above two points, we can basically reduce certain consumption in the application, but we often encounter different problems in the application of the plunger pump hydraulic motor, because the working standard of the hydraulic motor is unique, and there are six unique points that we must pay attention to when applying it. 1、 When it is necessary to start the application with full load, pay attention to the starting torque of the hydraulic motor. Since the starting torque of the hydraulic motor is shorter than the rated torque, if ignored, the organization may not be able to operate during operation. 2、 Since the back pressure type of the hydraulic motor is higher than the air pressure, the discharge oil pipes of the motor need to be led back to the car oil tank independently, and cannot be connected with the pump oil pipe of the hydraulic motor. 3、 Because the hydraulic motor will always leak, the inlet and outlet of the hydraulic motor will be closed to carry out the braking system, and it will still move slowly. When the long-term braking system is necessary, the braking system to avoid rotation shall be set again. 4、 When the inertia force of the driven parts is large (inertia torque is large or speed ratio is high), if it is specified that the braking system and example can be realized in a short period of time, and the running direction is straight, a valve (buffer valve) shall be set on the oil return passage to avoid a large hydraulic machine impact damage safety accident. 5、 When the hydraulic motor is the driving force component of the lifting or moving equipment, the speed limit valve must be set to prevent the lifting mechanism from speeding when it is rapidly descending or when the car or other elevators are descending, which may cause serious accidents. 6、 When using the quantitative analysis motor, if the starting and stopping are expected to be stable, select the necessary pressure control or flow monitoring mode when the control circuit and other elevators go downhill.
