The vacuum pump is a volume rotary blower. The two rotors are meshed by the synchronous gear at the rotor shaft end. The following points should be paid attention to when roots vacuum pump operates continuously under normal load:

1. The so-called rated load refers to the static pressure difference between the inlet and exhaust ports according to the rated pressure value on the name plate. In the case of normal exhaust pressure, it is necessary to pay attention to the pressure change at the inlet to avoid overload.

2. It is required to adjust gradually and slowly until the rated load is loaded. It is not allowed to adjust to the rated load once.

3. During the normal operation of the vacuum pump, it is strictly forbidden to completely close the inlet and outlet valves. It is necessary to observe the pressure regularly and whether the safety valve acts to exhaust when it is overloaded. Otherwise, the safety valve should be adjusted in time and overload operation is not allowed.

4. Pay attention to the location of lubricating oil, check regularly, and make records to ensure the oil quantity.

5. Due to the characteristics of Roots vacuum pump, it is not allowed to directly return the gas from the exhaust port into the air inlet of Roots vacuum pump for a long time (the temperature of the air inlet is changed), otherwise, the safety of the machine will be affected. If reflux adjustment is needed, cooling measures must be taken.

1. Daily check:

1) Oil level inspection: too much oil will increase the temperature, and too little oil will cause poor lubrication.

2) Temperature check: check the temperature of each part of pump with thermometer.

3) Motor load inspection: measure motor load with power meter, current meter and voltmeter.

2. Monthly inspection of vacuum pump: whether coupling and gasket are damaged and loose.

3. Check the vacuum pump every 3 months: whether the lubricating oil in the gearbox is deteriorated.

4. Check the vacuum pump every 6 months:

1) Whether the lubricating oil in the bearing box of the front cover is deteriorated.

2) Whether the piston ring and piston ring bushing are worn.

3) Whether the micro gear wear affects the normal operation of the rotor.

The above is the regular inspection of Roots vacuum pump. I hope that the introduction of Roots vacuum pump can help you.
