Description

Liquid pressing pumps mechanical axis lubricating structure

Technical field

The utility model relates to one can make rotating sleeve rotate on force-output shaft, mutual long time maintain good lubrication, there is force-output shaft and rotating sleeve reduces wear, increase the liquid pressing prolonging working life and pump mechanical axis lubricating structure.

Background technique

Press, be used in the sprayer device of air-conditioning purposes or horticultural use, generally must pressurize to liquid, when liquid just can be made to spray via fog head, obtain desirable spray effect, and the work of this liquid pressing, normally utilize liquid pressing pump to perform.Existing centrifugal blades type liquor pump, with infuse (lift) for primary concern, because hydraulic pressure is not high, sprayer device also cannot obtain good spray effect, existing scroll-type liquid pressing pump, though tool good fluid pressurized effect, only scroll machine assembly action rigorous is very high, and be commercially positioned in the factor of low unit price fabricating cost with regard to sprayer device, then it has the problem not comparatively being inconsistent economic benefit, existing curved shaft type trunk piston liquid compression pump, though liquid also can be made to obtain good pressurization, but it draws the pressurization pushing away plunger to produce to liquid by the bent axle of motor driving, but owing to considering that on bent axle, each crank-motion does not interfere with each other, this will make the axial length of bent axle become longer, the mechanical motion space needed is comparatively large, even liquid pressing portion must be separated making with dynamic power machine portion, comparatively consumptive material, overall volume is large, unfavorable Install and configure, No. I394893rd, existing TaiWan, China certificate of invention " doubly energy type liquid pressing pump " Patent Case is front invention (No. 2405137th, European Union's certificate of this case application, No. 8333572nd, U.S. Letters, Japan's No. 3170418th, certificate, novel No. 201020263943.0 of China), it is a kind of eccentric shaft type trunk piston liquid compression pump, come the liquid pressing in chamber by eccentric shaft interlock plunger, build has the advantage of Miniaturizable, but with regard to the action of the eccentric part drive plunger of eccentric shaft, even if eccentric part is arranged with pushing runner, by allowing this pushing runner rotated, the pushing of plunger end face is driven, can reduce or reduce the frictional resistance between eccentric part and plunger end face or wearing and tearing, but it still can because of the rotation insufficient lubrication between eccentric part surface and pushing runner, exist eccentric shaft and or pushing runner is mutual crosses the problem of quick-wearing, espespecially long-time when more than 1000Psi working pressure, this phenomenon is more aggravated and obviously, trace it to its cause, eccentric shaft is generally by quadrupole motor (without reducing gear), with the direct driven rotary of 1720 ~ 1740RPM rotating speed, work though eccentric part all soaks to put in lubricating oil with pushing runner, only both convolution speed is equal to the rotating speed of eccentric shaft, eccentric part and pushing runner carry out the centrifugal oil swirling action occurred when circling round at a high speed, except causing the lubricant oil on eccentric part surface and running off fast, the eccentric part of convolution dials the action of infiltrating eccentric part surface from lubricating oil jointly with pushing runner at a high speed, also can not supplemented before stopping convolution because of the lubricant oil run off, so that the problem just having insufficient lubrication exists, if in the course of action that can circle round at a high speed at eccentric part, can supplement the lubricant oil throwing loss away at any time, certainly will can overcome above-mentioned disappearance, increase prolong eccentric shaft and or pushing runner may use the life-span, when even working pressure reaches 2600Psi (high pressure), still can maintain eccentric shaft and the serviceability pushing runner.
