Roots vacuum pump and maintenance of exhaust filter element of treatment of vacuum drop

Please refer to the treatment of vacuum drop of Roots vacuum pump and maintenance of roots pump exhaust filter element, precautions for disassembly and assembly of Roots vacuum pump, treatment method of low vacuum of Roots vacuum pump, maintenance method of Roots vacuum pump exhaust filter element, etc.

Roots vacuum pump of precautions for disassembly and assembly

1. When disassembling and assembling the mechanical seal ring locating sleeve at the drive end, the position must be measured and remembered, so as to adjust the compression of the mechanical seal during reassembly.

2. When installing the single spring cover on the non driving side of Roots vacuum pump, ensure that the sealing ring of the movable ring will not turn over and the positioning spring is stuck in the positioning groove.

3. The disassembled and assembled parts shall not be hammered.

4. During disassembly and assembly, pay attention to the sealing surface without scratches and scratches.

5. Before reassembling roots vacuum pump, all parts and burrs must be cleaned.

6. When reassembling the roots pump pipe section, it must be confirmed that the locating pin between the pipe sections has been installed in place.

Roots vacuum pump of treatment of vacuum drop

1. The oil circuit in the pump is blocked or blocked, and a certain amount of oil is not reserved in the pump chamber. The solution is to check whether the oil circuit of Roots vacuum pump is unblocked and add the same type of vacuum pump oil.

2. Shaft seal steam supply is interrupted. Gland pressure regulating gas failure. Water entering the gland system, etc. The water of gland system shall be properly treated, and braking shall be carried out in case of serious.

3. Condenser water level is high. This is usually due to abnormal operation of condensate pump or pump failure. At this time, start the standby pump and stop the faulty pump for maintenance. If the hardness of condensate is very high, it can be judged that it is caused by the leakage of condenser copper pipe. In addition, improper operation of condensate and circulation is also the cause of this fault.

4. The empty system is not nervous. The confirmation method can use candle or special leak detector to detect the negative pressure pipeline, valve and condenser body, and eliminate the leakage point in time.

5. The circulating water temperature is too high. Circulating water is used to cool the working water of Roots vacuum pump. The high temperature of circulating water often reduces the pumping capacity and efficiency of vacuum pump.

Roots vacuum pump of maintenance method of exhaust filter element

1. Cleaning: the exhaust filter element of Roots vacuum pump is made of special materials, which is easy to be damaged and needs maintenance. After a period of use, some filtered impurities remain in the filter element of the vacuum filter. If the filter element is not cleaned in time, the pressure will increase and the transmitter will alert the police. At this time, it is necessary to clean and clean the exhaust filter element of the vacuum pump. During cleaning, pay attention not to deform or damage the filter element, otherwise it will affect reuse, reduce filtration efficiency, and even destroy the whole system.

2. Replacement: when replacing the exhaust filter element of Roots vacuum pump, water basin, towel and other supplies must be prepared in advance. There are many methods to replace the exhaust filter element of vacuum pump on the filter of ordinary vacuum pump. The filter element must be replaced according to the standard method to avoid damage to the filter element and prolong the service life of the exhaust filter element.
