Abstract
The utility model discloses a single-stage sliding valve vacuum pump, which adopts a two-cylinder parallel structure and has a pumping speed of 150L/s. The single-stage sliding valve vacuum pump comprises a pump body, an oil tank and a motor, wherein an air inlet is arranged in the pump body; an air outlet is arranged it the top part of the oil tank; the pump body is divided into two cylinders by a baffle plate; air inlets of the two cylinders are both communicated with the air inlet of the pump body; and the air outlets of the two cylinders are respectively connected with an air exhaust valve. An oil-gas separator and an oil tank cover plate are made of aluminum alloy materials, and parts between the pump body and a pump cover and between the oil tank and the oil tank cover plate are sealed with O-shaped sealing rings, so that the pump is portable to dismount in a maintenance process. The single-stage sliding valve vacuum pump has the advantages of good sealing performance, good wear resistance, small vibration, convenience in maintenance and long service life.
Description
Technical field
The utility model relates to a kind of pumping equipment, is specifically related to a kind of pumping speed and is 150 liters/second single-stage sliding valve vacuum pump.
Background technique
Industrial and civilian a large amount of occasions are all used vacuum pump.And 150 liters/second sliding valve vacuum pump is one of most widely used vacuum pump, and the sliding valve vacuum pump of old type is horizontal, and floor space is big; Vibration is big; But the guide rail in the vacuum pump of existing technology adopts split type sliding rod, and it is bigger to wear and tear in the using process, along with the growth of service time; Its wearing and tearing that slowly cause often cause degree of vacuum reduction, the pumping speed of vacuum pump to descend, and finally influence the working life of vacuum pump.
