[0003] The existing vacuum pump oil discharge device is composed of two parts: the oil discharge bolt and the sealing ring. When the oil is discharged, the oil discharge bolt needs to be unscrewed out of the oil tank. In the actual operation process, when the oil discharge bolt is unscrewed, the oil will occur The phenomenon of splashing is not conducive to recovery, and the splashed oil is difficult to clean up. In addition, when the staff cleans up, they will inevitably come into contact with the oil, which is not conducive to operation. The traditional oil discharge device also has poor sealing and is prone to oil leakage. , so in the process of use, it has brought a certain impact. Therefore, we propose a vacuum pump oil discharge device

The invention discloses a vacuum pump oil drainage device comprising an oil tank. The side wall of one side, in the horizontal direction, of the oil tank is connected with a bolt head in a threaded manner. A seal ring is connected at the connection portion between the side wall of each side, in the vertical direction, of the bolt head and the inner side wall of the oil tank in an embedded manner.The end, located in the oil tank, of the bolt head is connected with a threaded rod portion in a threaded manner. The outer surface of the threaded rod portion is provided with an oil outlet in the vertical direction. The side wall of the side, close to the oil outlet, of the bolt head is provided with a blind hole. The side, close to the oil outlet, of the outer surface of the bottom of the oil tank is provided with an oil drainage hole. A movable baffle is arranged in the oil tank and located over the oil drainage hole. The outer surface of the bottom of the movable baffle is connected witha support spring in a bolted manner. The vacuum pump oil drainage device is convenient to operate, avoid oil splashing absolutely, facilitates recycling and is free of environment pollution. In addition, the seal effect on the oil tank is improved, oil leakage phenomenon is not prone to happen, and a better use prospect is brought.
Description
technical field [0001] The invention relates to the field of vacuum pumps, in particular to a vacuum pump oil discharge device. Background technique [0002] The screw vacuum pump is a pumping device that uses a pair of screws to perform synchronous high-speed reverse rotation in the pump casing to generate suction and exhaust. The two screws are finely balanced and calibrated, supported by bearings, and installed in the pump casing. There is a certain gap between the screw and the screw, so when the pump is working, there is no friction between each other, the operation is stable, the noise is low, the working chamber does not need lubricating oil, the ultimate vacuum is higher, the power consumption is lower, and it is energy-saving and maintenance-free. Advantages, the oil drain device is one of the important components of the screw vacuum pump. [0003] The existing vacuum pump oil discharge device is composed of two parts: the oil discharge bolt and the sealing ring. W...
