The vertical mud pump and its sludge pipe are transported to the designated location. It consists of a clean water pump flushing system, a dredging pump, a submerged mud...
Hydraulic oil pumps and oil motors inevitably fail during use, and these faults can be classified into sudden and abrasive faults. Among them, the wear failure mostly occurs in the later stage of the system work, mainly due to the natural wear of the parts, and the damage caused to the system is mostly caused by the failure of the sealing material and the slowing of the moving speed of the actuator, which has little effect; Sudden faults often occur in the early stage of system operation and in...

1. Fault phenomenon and cause analysis Find the cause of the fault from the following three points during maintenance and improve the system: (1) Check the internal leakage of the boom cylinder. The simple method of zui is to raise the boom to see if it has a clear free fall. If the drop is obvious, remove the cylinder and check that the seal should be replaced if it is worn. (2) Check the control valve. First clean the safety valve and check if the spool is worn. If it is worn, it should be...
Concept: Nitriding is a process of infiltrating nitrogen into the surface layer of steel to improve surface hardness and wear resistance, as well as to improve fatigue strength and corrosion resistance. It uses ammonia gas to decompose the active nitrogen atom when heated, and is absorbed by the steel to form a nitride layer on the surface and diffuse to the core. Nitriding is usually carried out using specialized equipment or a well type carburizing furnace. Applicable to all kinds of...

Regarding the problem of the motor insulation for the hydraulic oil pump, Dalan Motor Xiaobian said and said that it is important. Today, Xiaobian will bring you to learn more about the related knowledge of motor insulation, and learn from everyone. 1. The current in the insulation consists of three parts: Instantaneous charging current: generated by the displacement polarization of the geometric capacitance of the medium, gradually decaying with time, expressed as ic. Absorption current:...
According to the three principles of analysis and energy supply, the following important conclusions can be obtained: There can only be one operation in the forward channel of the control system, that is, only the integral operation can be used, and in order to ensure the stability of the control system and the ideal control characteristics, variables must be provided. The differentiation, due to avoiding the differentiation of the input parameters, the differential of the controlled variables...

“Warm rise” is an important parameter for measuring and evaluating the degree of heat generation of a special motor for a hydraulic oil pump. It is measured under thermal equilibrium at the rated load of the motor. The terminal customer perceives that the motor is good or bad. The usual practice is to touch the motor and see how the temperature of the housing is. Therefore, when talking about the motor, it has to mention "temperature rise". "Wensheng" is in the shadow of the...
