Description

Nose balance formula high-pressure gear pump

Technical field

The new reason of this practicality belongs to hydraulic element, particularly a kind of nose balance formula high-pressure gear pump.

Background technique

In high-pressure gear pump; The size of compensation area has determined the working life of pump, and area is excessive, and then side plate is stressed also big; Side plate is worn and torn too early or burn out; But compensate too small user's the usage requirement of having satisfied not, limited the using scope of high-pressure gear pump, if excessive working life of reducing pump again.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned technical deficiency, and a kind of compensation appropriateness is provided, and operates steadily the nose balance formula high-pressure gear pump of long service life.

The technological scheme that the utility model technical solution problem adopts is: nose balance formula high-pressure gear pump comprises protecgulum, locating stud, the pump housing, bonnet, self oiling bearing, attachment screw, seal ring, driving gear shaft, driven gear shaft, outside framework oil seal, oil sealing gasket, back-up ring; The outside end face that is characterized in side plate is provided with one 3 word spill compensating tank; Loaded 3 word Stamping Steel Ribbons and 3 word blend stops in the 3 word spill compensating tanks, 3 word blend stops place the inboard of 3 word Stamping Steel Ribbons.

The beneficial effect of the utility model is: nose balance formula high-pressure gear pump has solved high-pressure gear pump nose balance problem at work; Improved the working efficiency of high-pressure gear pump; Prolonged the working life of high-pressure gear pump; Enlarge the using scope of high-pressure gear pump, can satisfy multiple requirements of different users.
