Description

The triplet high-pressure gear pump
Technical field
The utility model belongs to hydraulic element, particularly a kind of triplet high-pressure gear pump.
Background technique
High-pressure gear pump generally has simply connected and double linked, but in the high-pressure gear pump using process, according to the actual demand of host function; Sometimes often need on the basis of bigeminy high-pressure gear pump, add again and join a simply connected high-pressure gear pump, sometimes because the compact restriction of complete machine internal structure can't be satisfied the setting of this structure; And this set needs loaded down with trivial details pipeline to connect; Increase leakage point, be not easy to maintenance, also influenced the Performance And Reliability of main frame simultaneously.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, and a kind of compact structure is provided, and is convenient to maintenance, triplet high-pressure gear pump easy to use.
The technological scheme that the utility model technical solution problem adopts is: the triplet high-pressure gear pump comprises outside framework oil seal, protecgulum, the pump housing one, the pump housing two, the pump housing three, main shaft one, main shaft two, main shaft three, from axle one, from axle two, from axle three, bonnet, side plate, self oiling bearing; Be characterized between the pump housing one and the pump housing two, seal with the locating stud location and with seal ring between body one and middle body two, middle body one and the middle body two in all being equipped with between the pump housing two and the pump housing three; On the middle body one coupling is housed; Be provided with internal spline and isolation channel in the coupling; Between main shaft one and the main shaft two, connect with coupling between main shaft two and the main shaft three, the coupling internal spline is connected with the external splines of main shaft one, main shaft two, main shaft three respectively.
The beneficial effect of the utility model is: triplet high-pressure gear pump compact structure, and leakage point is few, is convenient to maintenance, and the life-span is long, good seal, stable performance, noise is low, can satisfy the demand of high-pressure and hydraulic equipment fully.
