The pump shaft drives the eccentric wheel and is rotary motion during the pump operation, and eccentric wheel drive guide rail is the rotatory compound movement that rocks and is realized breathing in the exhaust process in the pump chamber, and the outer oil feeding house steward of the pump body lubricates for guide rail and cavity for operation part in the pump body obtains the sufficient lubrication, is favorable to inhaling, carminatively goes on fast.
Description
Technical field
This utility model relates to a kind of vacuum pump, particularly relates to a kind of sliding valve vacuum pump.
Background technology
Sliding valve vacuum pump has a cavity, and cavity is built with guiding valve and eccentric, equipped with air bleeding valve on cavity, is changed the size of chamber intracorporeal space by eccentric rotation in cavity, thus reaching the purpose being sucked from guiding valve by gas and discharging from air bleeding valve.
The oil-air pressure produced during the operating of existing guiding valve causes that the lubrication of connector and slide valve lever and little cylinder is insufficient, and top is bigger than normal and cause oil gas to backflow to air inlet, the vacuum of influential system and oil vapour pollution due to gap.
Accordingly, it is desirable to provide a kind of new technical scheme solves the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sliding valve vacuum pump that can improve slide unit lubricant effect.
For solving above-mentioned technical problem, sliding valve vacuum pump of the present utility model, it includes the pump housing, it is provided with guide rail in the described pump housing, it is provided with pump shaft in the cavity of the described pump housing, described pump shaft is provided with guiding valve and eccentric, described guiding valve upper end connects slide valve spindle, described slide valve spindle slides in guide rail, the side of the described pump housing is provided with air inlet, described air inlet place is provided with drainage screen, described air inlet is connected with pump housing suction muffler, the top of the described pump housing is provided with outlet passageway, described outlet passageway is connected with valve pocket lid, described valve pocket lid is connected with pump housing outlet chamber, described pump Ligation in vitro oil supply house steward, described oil supply house steward leads to the cavity of guide rail and the pump housing by oil supply branch road, it is provided with cooler in the described pump housing.
Described eccentric has multiple fabrication hole.
It is equipped with cushion bottom the described pump housing.
The beneficial effects of the utility model: during pump operation, pump shaft band movable eccentric wheel rotates, eccentric drives guide rail to do rotation in pump chamber and rocks compound motion and realize air-breathing exhaust process, oil supply house steward outside the pump housing is lubricated to guide rail and cavity, make the operation parts in the pump housing obtain sufficient lubrication, be conducive to inhaling, quickly the carrying out of aerofluxus.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
