问：我的Central outlet系统为什么压力表不动，水箱液位监测到低液位报警还不进水？

Answer: This is a common question that may be related to the working principle and specific faults of the system. The following is a brief explanation of the working principle of the central water outlet system, to facilitate troubleshooting:

Working principle:

1. * * Initial filtration * *: The cutting fluid is pumped by a lift pump to a vortex separator for filtration, where larger impurities are separated from the coolant by the centrifugal force of the vortex separator.
2. * * Secondary filtration * *: The relatively clean coolant flows into the bag filter barrel for secondary filtration, and then into the water tank.
3. * * Triple filtration * *: The high-pressure screw pump pumps the coolant from the water tank to the pipeline filter for triple filtration.
4. * * High pressure water outlet * *: The coolant that has been filtered multiple times is transported through pipelines to the tool water outlet hole, forming high-pressure water outlet.

Based on these steps, the corresponding working components of the fault can be preliminarily identified.

Q: Why does a clogged bag filter cause abnormal water level in the water tank and prevent water from entering the system?

Answer: Bag filter blockage is one of the common faults in the central water outlet system, and the main reasons are as follows:

1. * * Slow water intake * *: Blockage of the bag filter causes slow coolant intake into the water tank.
2. * * High pressure pump suction * *: When the system is working, the high-pressure pump continues to pump water from the water tank, but due to clogged filter bags and insufficient water level in the tank, the high-pressure pump suction occurs.
3. Pump unit damage: Air suction can cause significant damage to high-pressure pump units.

Q: How to solve the problem of clogged bag filters?

Answer: To solve the problem of clogged bag filters, the following measures can be taken:

1. Check the filter: When the water tank level is found to be abnormal, first check whether the bag filter has accumulated too many impurities.
2. * * Increase filtering accuracy * *: Improving filtering accuracy is a reliable approach. For example, our company's central effluent system uses three filters:
-Vortex pre filtration
-Bag filter (for handling relatively clean coolant)
-Pipeline filter
3. * * Extended filter bag replacement cycle * *: In harsh working conditions, the three filters greatly extend the system's bag replacement cycle.

Q: How to provide a detailed explanation of the pressure gauge and liquid level alarm faults in the future?

Answer: Afterwards, we will provide a detailed introduction to pressure gauge and liquid level alarm faults to help everyone better troubleshoot and solve these common problems.

Summary: By understanding the working principle and common faults of the central water outlet system, everyone can preliminarily troubleshoot the system faults and take corresponding solutions. I hope these answers can be helpful to you.
