Description

For the extra long life hydraulic oil pump device of jack
Technical field
The utility model relates to a kind of extra long life hydraulic oil pump device for jack.
Background technique
The pump core of existing jack in use causes because one end seals completely that the pump core the other end does not have lubricated to cause that frictional loss is large in sliding process, the working life of reducing pump core, the problem that reduces the working efficiency of jack.
Summary of the invention
The utility model is large for the pump core frictional loss of existing jack, the working life of reducing pump core, the problem that reduces the working efficiency of jack, has proposed a kind ofly to reduce frictional loss, improves pump core working life and has improved the hydraulic oil pump device for jack of jack working efficiency.
Extra long life hydraulic oil pump device for jack described in the utility model, the pump core, valve body, stage clip, press spring base and the sheath that comprise the pump housing, mate with pump housing inner chamber, the lower end of the described pump housing is arranged in the groove of valve body, and between described pump housing bottom and valve body recess, is furnished with pump housing sealing copper packing; Described compression spring sleeve is connected on described pump housing outside, and described stage clip one end is fixed on valve body, the other end is arranged on described press spring base; Described press spring base is arranged on the upper end of described pump core, and described sheath is connected with described press spring base, and described sheath is enclosed within the outside of described stage clip; Described pump core and the described hand of pressing are coupling, and the roller on the roller bearing pin of pressing hand of the top end face of described pump core and jack rolls and is connected, the lower end periphery of described pump core be furnished with for nylon back-up ring and the y-type seal ring of pump housing inner wall sealing, filling liquid force feed in the cavity that described pump core lower end surface and the pump housing form, it is characterized in that: described pump core lower end outer side wall is provided with annular pump housing oil storage tank, in described pump housing oil storage tank, fill for lubricated lubricating grease.
The contacting point of described press spring base and described pump core is furnished with Steel Cable Baffle Ring.
Pump core oil storage tank working procedure: be subject under roller external force, the lubricating grease of noting in pump core, y-shaped ring, nylon back-up ring and pump housing oil storage tank, capital is along pump housing internal surface, and along moved by force direction, lubricating grease plays lubrication to pump core, pump housing surface; In the time that external force is cancelled, the lubricating grease of noting in pump core, y-shaped ring, nylon back-up ring and pump housing oil storage tank again can be along pump housing internal surface under the effect of stage clip restoring force, motion round about, and lubricating grease plays lubrication to pump core, pump housing surface.
The beneficial effects of the utility model are: adopt this device, can effectively reduce frictional loss, improve pump core working life and improve jack working efficiency.
