Troubleshooting of Four Faults of Hydraulic Motors Ⅱ
1. crawl The reasons may be: unstable leakage, damage to the motor support frame, changes in bearing positioning, wear of parts, serious oil contamination, and the wrong phase between the distribution shaft and the guide rail surface, causing inaccurate oil distribution and inconsistent forward ...Read more -
Troubleshooting of Four Faults of Hydraulic Motors
Weak rotation: The reason is: insufficient output pressure and flow of the main pump or increased clearance between the internal fitting parts of the hydraulic motor. Checking and troubleshooting methods: (1) On the premise that the main circuit safety valve, overload valve and other accessories...Read more -
Analysis of the cause of failure of vane pump ②
The reasons for loose bearings and oil leakage from shaft seals are as follows: A. During installation, the output shaft of the vane pump and the motor output shaft are not concentric (the motor output shaft is deformed, the coupling is not concentric, the positioning gap of the vane pump’s...Read more -
Analysis of the cause of failure of vane pump ①
The causes of vane pump failure are generally reflected in: loud noise, pressure oscillation, system pressure loss, no pressure, system oil temperature is too high, etc. A. The main causes of noise produced by vane pumps include the following phenomena: 1. The vane pump sucks air when it is worki...Read more -
The annual maintenance process of mechanical equipment in hydraulic systems ②
2. The hydraulic oil should be replaced three months after the first use of the hydraulic system, and then every six months to ensure the normal operation of the system. 3. During the operation of the hydraulic system, the oil filter should be checked for blockage at any time and the filte...Read more -
The annual maintenance process of mechanical equipment in hydraulic systems ①
1. It is more economical to perform regular maintenance and service checks on hydraulic systems than to repair them after a fault occurs. It is recommended that after a certain working period, regular preventive maintenance be performed on the system and important sealing materials should be repl...Read more -

How servo pumps work.
Servo pump uses a servo motor to control the hydraulic pump and provide power source to the hydraulic cylinder to form a servo pump. The difference from a simple power pump is that the power pump has a single output, while the servo pump can be precisely controlled due to the servo motor, because...Read more -
Working Principle and Maintenance of Hydraulic Pump
1. Working principle of hydraulic pump Hydraulic pump is an important device of hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to realize oil absorption and pressure. Hydraulic pumps have the advantag...Read more -
What Maintenance Does The Vane Pump Usually Require?
The usual maintenance and operation of vane pump components: 1. Due to sudden power failure, the system working pressure fluctuates, the system negative pressure is discharged, and the bubbles are dissolved in the liquid, resulting in the presence of steam in the high temperature oil pump or pip...Read more -
How to Solve the Serious Noise Problem of Vane Pump?
There are many noise problems encountered during the use of vane pump. Sometimes, if it is only a small noise, there may not be a big problem. However, if there is a serious noise problem, we have to pay attention to it. Here we will tell you in detail how we should deal with it if there is a se...Read more -
VQ Pump Uses Different Directions Depending on the Performance
VQ pump uses different directions for different performance? Usually we all know that VQ vane pump has its own advantages and disadvantages when operating on the machine, of course, VQ pump is an important device of hydraulic system. It relies on the blades to reciprocate in the cylinder body to...Read more
