Abstract

Motor-driven preumatic grease injector, the present invention relates to a kind of charging point that is applicable to mechanical transmission component filling lubricant grease, it mainly solves hand grease gun by manual operation, and the store oil amount is few, troublesome poeration, labor intensity is big, and oil injecting speed waits problem slowly, the present invention includes a power operation case, air pressure oil tube, double sealing piston and pneumatic control valve, speed control valve and fuel feeding valve etc., when pressurized gas enters air pressure oil tube by air hose, promote double sealing piston, the butter pressurized enters working state in the piston the other end, presses the fuel feeding valve on the oil hose, butter can inject oil nozzle, and air pressure oil tube adopts steel pipe processing.

Description

Motor-driven preumatic grease injector

The present invention relates to a kind of charging point that is applicable to mechanical transmission component filling lubricant grease, the annotate equipment of butter of specifically a kind of air pressure that utilizes electric air compressor.

Before the present invention proposes, oil nozzle filling butter to machinery, generally all be with grease gun by the operator with hand-held be support, constantly driving handle moves plunger repeatedly, butter filler is gone into the oil nozzle of machinery, this traditional grease press structure, utilizing spring to promote piston by the operator in the cylinder barrel is pressed into butter in the plunger oil pocket and works, therefore fully store oil in the grease press structure cylinder barrel, and because the spring force effect makes troubles for the interior butter that adds of cylinder barrel, the butter speed of annotating simultaneously is slow, and operator's labor intensity is big.

The purpose of this invention is to provide a kind of motor-driven preumatic grease injector, to solve hand grease gun by manual operation, and the store oil amount is few, troublesome poeration, labor intensity is big, oil injecting speed waits problem slowly, and this butter annotating device can also be suitable for the filling of various lubricant greases or other liquid simultaneously, and can be used for tyre inflation.

Specific design scheme of the present invention is to realize by the following method.This motor-driven preumatic grease injector, it comprises a powered case, air pressure oil tube, double sealing piston and pneumatic control valve, speed control valve and fuel feeding valve, in the powered case, be provided with small-sized electric air compressor and storage battery, charger, in air pressure oil tube, be provided with double sealing piston, this double sealing piston is unidirectional movement (promotion) under the effect of pressurized gas, be provided with end cover at the two ends of air pressure oil tube, be connected with air hose by on the end cap of double density piston one end, the other end of air hose is connected with the gas output end of electric air compressor, and the pressure of gas output and speed connect an oil hose by pneumatic control valve and speed controlling valve regulation on air pressure oil tube the other end end cap, its oil hose is provided with fuel feeding valve, with the control oil filling amount.The power operation case is arranged on the support on the air pressure oil tube, and the power operation case adopts knot that can be undone by a pull to be connected with support, for the ease of oiling work, is provided with work light by oil hose one side on the power operation case, is provided with four universal wheelss in the oily lower end of air pressure simultaneously.

The present invention has realized its purpose fully in actual tests, its not only store oil amount is big, and speed is fast, easy to operate, alleviated labor intensity of operating personnel greatly, simultaneously owing to can be suitable for various lubricant greases, enlarge the oiling kind, and can also be automobile tyre inflation.Also can use air pressure oil tube separately, independently carry out oiling work by other compressed gas source air feed.

Further use description of drawings structure of the present invention and working procedure below, accompanying drawing provides structural representation of the present invention, among the figure, (1) powered case, (2) pneumatic control valve, (3) speed control valve, (4) air hose, (5) air pressure oil tube, (6) double sealing piston, (7) butter, (8) universal wheels, (9) oil tube end cap, (10) oil hose, (11) fuel feeding valve, (12) oil outlet, (13) work light, (14) support.After connecting power supply, the pressurized gas of the electric air compressor output in the powered case, through pneumatic control valve and speed controlling valve regulation, enter air pressure oil tube by air hose, promote double sealing piston, the butter pressurized enters working state in the piston the other end, the oil outlet of oil hose is connected on the oil nozzle of the machinery that needs the filling butter, press manual fuel feeding valve and carry out oiling, unclamp manual fuel feeding valve, oiling stops automatically.

During the invention process, air pressure oil tube adopts steel pipe processing, and its internal diameter precision is

More than 7, will add the round gasket river on the air pressure oil tube two end cap, the present invention makes simply, and cost is low.
