How to solve the smoke and fuel injection problems of Dalian chemical pumps

After a certain period of use, Dalian Chemical Pump may emit oil fumes at the exhaust port due to poor maintenance. The exhaust filter of the chemical vacuum pump is a consumable component that plays a role in separating oil and gas inside the vacuum pump, preventing the vacuum pump oil from being discharged from the vacuum pump body along with the exhaust gas;

Settle the filtered vacuum pump oil and reflux it back into the oil tank. When the exhaust filter fails, the exhaust filter will no longer function as a filter and will discharge the vacuum pump oil with the exhaust gas;

The specific manifestation is that there is white or blue oil smoke at the exhaust port, and it is generally recommended to replace it after 3-6 months of use. In industries with severe pollution, the replacement time will be shortened.

Smoking - If the pump has just started running and there is smoke, it is normal. If it continues to smoke for a long time, it is abnormal.

Solution: Smoking indicates that there are repairs to the outside of the pump's intake port, including pipes, valves, and containers. After leak detection, the smoke will end. Vortex flowmeter.

Fuel injection - indicates that there are a large number of leakage points outside the intake port, and even the intake port is exposed to the atmosphere.

Solution: Seal the inlet of the pump to allow it to operate. If there is no oil injection, it indicates a leak point; The exhaust valve plate is damaged. Check if the exhaust valve plate is damaged and replace the damaged exhaust valve.

If the problem with the vacuum pump is not very serious, you can disassemble the vacuum pump yourself, replace the vulnerable parts of the vacuum pump, and then clean and assemble the vacuum pump to achieve the purpose of maintaining the vacuum pump.

Proper maintenance of vacuum pumps can reduce the difficulty of repairing them. Proper maintenance of vacuum pumps is necessary to better use them. The following are some suggestions for vacuum pump maintenance:

Rotary vane vacuum pumps should be installed in a clean and hygienic environment, without any debris, dust, water sources, or areas with excessively high temperatures;

When installing a vacuum pump for the first time, check if the motor is rotating in the correct direction, that is, if the motor is rotating in the same direction as the rotor inside the pump. Generally, the normal operating direction of the motor is marked above the motor;

Before starting the vacuum pump after a long shutdown, it should be started intermittently multiple times;

After using the vacuum pump, it should be drained;

The oil temperature should not exceed 75 degrees Celsius during the operation of the vacuum pump;
