Improve as one of the present utility model, described oil circuit changing valve and the joining port of described vacuum pump oil box are provided with O type ring recess.For placing the O type circle playing seal action.
Improve as one of the present utility model, described oil cooler is radiator.
Improve as one of the present utility model, the longitudinal cross-section of described minor axis joiner is up-thin-low-thick " ten " word shape, its upper end is provided with outside thread, and lower end is provided with internal thread, and offers up-narrow and down-wide cylindrical hole at the center of described minor axis joiner.
Improve as one of the present utility model, scyewed joint is passed through in the upper end of described oil strainer and described minor axis joiner, the lower end of described vacuum pump oil box and described minor axis joiner is by scyewed joint, and described oil circuit changing valve is socketed in the lower end of described minor axis joiner.
Improve as one of the present utility model, the oil outlet on described oil circuit changing valve is connected with the central through bore on described minor axis joiner.
Improve as one of the present utility model, between described oil cooler and oil pipe, adopt scyewed joint.
Relative to prior art, the utility model is on the basis of integrity ensureing the original oil pipe of vacuum pump, by installing an oil circuit changing valve at the joint of vacuum pump oil box and oil strainer, and adopt minor axis joiner to position, and on oil circuit changing valve external radiator, the oil that flows out in fuel tank is first flowed out through oil strainer and is switched oil circuit by oil circuit changing valve flow to thus flow to after outside radiator carries out radiating treatment, again through oil circuit changing valve stream fuel tank, reach the effect that pumping fluid cools fast, this mode substantially increases oil cooled speed, extend the maintenance interval of vacuum pump and reduce cost, also improve the service behaviour of vacuum pump simultaneously.
