Summary
Let's talk about the preparation before the start of Roots vacuum pump unit: Roots pump water ring vacuum unit chooses water ring pump as the front pump. The reason why it chooses water ring vacuum pump is that the Roots liquid ring vacuum unit formed by this combination has more advantages. In order to ensure the normal operation of Roots vacuum pump unit, special attention should be paid to the preparation work when the equipment starts. Let's learn how to operate it.

Preparation before starting Roots vacuum pump unit
The Roots pump water ring vacuum unit uses the water ring pump as the front pump. The reason for choosing the water ring vacuum pump is that the Roots liquid ring vacuum unit formed by this combination has more advantages. In order to ensure the normal operation of the Roots vacuum pump unit, Special attention should be paid to the preparations when the equipment starts, let us learn how to operate it.
Roots vacuum pumpThe general starting steps of the unit can be divided into the following points:
1. Check whether the water level of the water pump and water tank exceeds 3/4 of the water tank. Deficiencies are made up.
2. Check whether the water used in the water tank is clean, and do not use sewage containing sediment to avoid blocking the pipeline.
3. Check whether the drain valve of the buffer tank at the bottom of the intermediate pump is closed.
4. Check whether the unit circuit is in good condition and whether the control cabinet indication is normal.
5. Check the oil level of the lubricating oil in the engine body. The oil level needs to reach more than 3/4 of the oil window. At the same time, check the color of the lubricating oil. If there are more ru white or black impurities, notify the operator that the lubricating oil needs to be replaced.
6. Check the circulating cooling of the intermediate pump and the main pump, check whether the cooling water channel is intact, open the cooling water inlet and outlet valves, and check whether the circulating cooling water is normal.
7. Check whether the starting pressure of the middle pump and the main pump of the motor pressure gauge of the unit is normal.
8. Only after checking and confirming the above items can the Roots vacuum unit be started.
Roots vacuum pumpOperating Procedures
There are many types of Roots vacuum pumps. We should not only know the operation rules of Roots vacuum pumps, but also know the problems often mentioned by users during use, such as the installation of multi-stage Roots vacuum pumps and Roots water ring vacuum pumps. Whether the Roots vacuum pump can be used alone, and which water ring Roots vacuum pump manufacturer is better, we can make a full judgment.
To startRoots vacuum pump, The first step is to start the front pump; then open the pre-pump valve of the front pump and the intake valve of the Roots vacuum pump; when the system pressure reaches the allowable pressure of the Roots vacuum pump, close the pre-pumping valve and start the Roots pump. If there is no pre-pumping pipeline and valve, start the Roots pump after reaching the starting pressure. This process can also be automatically controlled by the pressure sensor to realize the automation of the whole process; According to the actual situation of the vacuum system, if it is not a large vacuum system, you can start the front pump first, and then start the Roots vacuum pump. If it is a large vacuum system, although the Roots pump with overflow valve has overload protection, this protection only protects the motor, and the Roots pump itself will still It will be overheated and stuck due to long-term work under high pressure. Therefore, the Roots pump should be started after the previous pump reaches a certain pressure.
All right, let's talk about it. Thank you for watching. Let's see you next time.
