Rotary vane vacuum pump maintenance must pay attention to what problem? - - - - - -

rotary vane vacuum pump is one of the most basic vacuum to obtain equipment in vacuum technology. Rotary vane pump is small and medium-sized more pumps, rotary vane vacuum pump, which has two kinds of single stage and double stage. Rotary vane vacuum pump to ensure the operation efficiency of regular maintenance and repair, the new rotary vane vacuum pump overhaul and idle running also need to go through to test equipment, the need to pay attention to in the vacuum pump repair what problem? Come with small make up the specific look at:

rotary vane vacuum pump is the basic equipment for vacuum, it can be used alone, or as the backing pump of all kinds of high vacuum system and drainage pump. But it is not suitable for pumping corrosive to metal, chemical reactions to pump oil and gas containing dust particles, high oxygen to body, explosive gas.

in the vacuum pump repair need to pay attention to what problem? There are mainly six is as follows:

1. New rotary vane vacuum pumps, after back to unpacking check, check the pump is damaged in the process of loading, the next thing to pump installed in accordance with the instructions, connected to the electricity, water cooling water pump.

2。 In the operation of the equipment to know to, if not clear to want to use other methods available, open the pump suction is positive, wind power is the reverse.

3。 Rotary vane vacuum pump oil for many reasons, common have return oil or reverse injection, to avoid this situation, will the pump mouth open, first through right to the oil pan into the fuel tank, add oil in the correct oil level.

4。 The use of the gas ballast valve is basic on the two points, one is in a higher relative humidity, secondly, the pump is pumping gas steam class is contained in liquid.

5。 Ball valve installation is necessary, because if the installation between regulation and tested pump will reduce the damage to regulate, prolong life.

6。 Choose rotary vane vacuum pump oil should also be in accordance with the requirements for model and choosing the right vacuum pump oil.

about rotary vane vacuum pump maintenance, our maintenance staff give advice:

1. Vacuum water pump use after a period of time by pumping gas impurity, and polluted the vacuum pump, affect the vacuum water pump, vacuum pump oil at this time must be replaced. Operation is put net the old oil first, then the suction mouth into a small amount of new oil, a few turn plate fixed pulley hands, make the new oil pump body to clean once, and then released, the last inject enough new oil.

2。 Must always keep X-ray A clean environment around 63 rotary vane vacuum pumps, pump and pipeline itself, must often wipe and clean and pay attention to the oil flow, cooling water temperature, vacuum indicators, In the vacuum degree of operation after a certain period of time allowed to drop, but should not exceed half an order of magnitude) And noise is normal, whether the belt is too loose, the motor is normal.
