Roots vacuum pump how to add non-stop lubricating oil

The biggest advantage of Roots vacuum pump is lower inlet pressure with higher pumping rate, and can reach a relatively high ultimate vacuum pump. Therefore, Roots vacuum pump running stable performance, long service life, low maintenance costs, welcomed by everyone, but also found in the production activities Roots vacuum pump every time to be added to the parking lot, affecting production. So how to improve this problem? Here to explain Roots vacuum pump how to add non-stop lubricating oil. Roots vacuum pump how to add non-stop lubricating oil From the Roots vacuum pump structure can be found, synchronous steering gear box and Roots pump cavity is sealed by the internal seal, Roots vacuum pump operation in the pump cavity to form a certain vacuum Degrees, the gear box and the pump chamber will produce pressure difference, under the pressure difference, the oil will enter the pump chamber along the oil seal. Only when the gear box and the pressure in the pump chamber are balanced will the lubricating oil stop to enter. With Roots vacuum pump running for a long time, the gearbox oil will gradually be sucked into the pump chamber, showing the fluid below the standard level, then stop, add oil from the lubricating oil hole, or gearbox Lubricating oil will be quickly sucked into the pump chamber due to the pressure difference between the atmosphere and the pump chamber. In view of this situation, consider connecting the gear box and Roots vacuum pump inlet to balance the pressure difference, so that the pump chamber and gear box to maintain the same degree of vacuum. In the lubricating oil hole to install a special large oil cup, made of polytetrafluoroethylene turning the cup, in order to avoid the loss of vacuum caused by leakage of the cup hole problem, install a isolation valve in the lower part of the cup. When the Roots pump is running, the ball valve on the underside of the oil cup is in an open state. When the oil level of the Roots pump needs to be reduced, close the ball valve and open the screw cap on the top of the oil cup for filling. After the above operation and then added Roots vacuum pump no longer need to stop processing, both to ensure equipment operation, but also solve the problem of production downtime. (Editor: Li Juan)
