Solutions to common faults in hydraulic stations

In order to ensure that the hydraulic station can work normally, we still need to understand the solutions to some common faults in the hydraulic station. The automatic screen changer manufacturer will now introduce to you:

When we start the oil pump according to the correct requirements and wait for a while, if it is found that the overflow valve in the electro-hydraulic pressure regulating device does not return oil, and the pressure gauge shows zero, it means that the oil pump cannot suck oil. In view of this situation, we need to first check whether the shut-off valve of the oil pump suction port of the hydraulic station is open. If it is not open, open it immediately. Then turn the motor reverse, you can see that the oil surface is tumbling, and if it rotates forward, the oil will be sucked up and pressured.

In fact, another method can be used, which is to unscrew the oil suction pipe in time, fill the oil at the suction port, and rotate the oil pump. At this time, you can hear the sound of oil suction, and you can see the spray at the oil outlet. Oil, then it means that the oil pump of the hydraulic station has resumed its normal working condition.

Another common problem is that as the oil pressure in the hydraulic station system continues to rise, when it reaches a certain level, the oil pressure gauge will experience high-frequency vibration, which will bring adverse effects. The reason for this situation is that, on the one hand, the pressure regulating device is a flexible element in the hydraulic system, so if the natural frequency of the small spring is close to the pulsating frequency of the oil pressure of the oil pump, high frequency will appear. vibration.

On the other hand, the reason is mainly due to the uneven air gap, which will cause some parts in the hydraulic station to be in an unbalanced state. Therefore, the voltage should be adjusted in time to maintain a stable state, and the gap of the magnetic steel should be adjusted uniformly.
