Problems solved by technology

[0003] The oil injection pump products of the same kind abroad adopt the pull-type oil injection method. Its structure is that the oil storage device and the main engine are integrated, and it has a complete set of components such as connecting pipes, nylon pistons, four-legged valves, lifting rods, and lifting plates. The structure is complex. A large amount of maintenance; the principle is: rely on the working frequency of the lifting device to ensure the pressure of the oil injection port, and a slight fluctuation of the compressed air will directly affect the pressure value of the oil injection port, making the pressure of the oil injection port unstable

Abstract

A pneumatic self-sucking type high-pressure oil filler is composed of the oil storage unit consisting of oil storage cylinder and big piston, the oil filling unit consisting of plunger and check valve, the pneumatic unit communicated via interface to the compressed air source and connected via moving rod to plunger, and operation program controller. Its advantages are simple structure, low cost, and high effect to fill a great deal oil in short time.

Description

technical field [0001] The invention relates to an oil injection device, in particular to a pneumatic self-suction high-pressure oil injection device. Background technique [0002] In the prior art, the mutual moving parts of mechanical equipment, especially the high-speed rotating parts, should be lubricated with grease to reduce friction. Usually, the oil guns with this maintenance function are mostly manual, with small oil output, long filling time, and small capacity of the accompanying oil storage tank. It is not suitable for the working environment with multiple use points, large filling volume and short filling time. [0003] The oil injection pump products of the same kind abroad adopt the pull-type oil injection method. Its structure is that the oil storage device and the main engine are integrated, and it has a complete set of components such as connecting pipes, nylon pistons, four-legged valves, lifting rods, and lifting plates. The structure is complex. The ma...
