Technical maintenance operations for laboratory oil-free vacuum pumps

Source:

The laboratory oil-free vacuum pump is a rotary vane single-stage vacuum pump. A basic device used to remove gas from a sealed container to obtain a vacuum.

The laboratory oil-free vacuum pump can be used for various vacuum operations such as air conditioning, refrigeration equipment repair, medical equipment suction, printing machinery, vacuum packaging, vacuum absorbing, physical and chemical experiments, and small devices that require a vacuum environment. It can also be used as a foreline pump for small oil booster pumps, oil diffusion pumps, molecular pumps, etc.
Laboratory oil-free vacuum pumps are not suitable for the removal of gases that are corrosive to ferrous metals, chemically reactive to pump oil, contain particulate dust, and toxic gases that are too high in oxygen and explosive. It cannot be used as a transfer pump (ie, pumping from one container to another).
Laboratory oil-free vacuum pump maintenance
1. It should have adequate ventilation conditions and an ambient temperature below 40 °C.
 2. Clean place without dust and dirt.
 3. Water, oil and other liquids will fall onto the pump.
 4. Not directly exposed to the sun.
 5, there is enough space to facilitate the inspection, maintenance and assembly of the pump.
 6. The pump must be mounted on a flat surface.
 7. Zui is good to install the pump on a concrete-like foundation. If there is no condition, the pump can be firmly mounted on a steel or wooden frame.
 8, must ensure that the pump does not cause vibration due to the foundation is not strong.
 9. The pipeline connected with the laboratory oil-free vacuum pump should not be too long and less than the inlet diameter of the pump, which affects the pumping speed. Also, check whether the vacuum connection pipe is leaking.
10. When connecting the wires, pay attention to the wiring requirements specified on the motor nameplate. The three-phase electric pump should pay attention to the direction of rotation of the motor should be consistent with the direction of the marked arrow on the pump.
