Problems solved by technology

[0002] At present, the oil pumping unit in the oil field is lubricated with grease. During the repair or maintenance process of the pumping unit, the grease injection of the moving parts is generally manually operated with a grease gun. When adding butter to crank pins, maintenance workers have long used manual grease guns at high altitudes. First, the filling time is long and the work efficiency is low. Second, the viscosity of the butter is high and it is difficult to fill in winter. Workers work at heights for a long time, which is prone to safety accidents

Abstract

The invention discloses an oil injection pump and belongs to the technical field of mechanical lubricating. The oil injection pump comprises a pump body, an oil channel, an oil outlet, a vacuum hood, an oil dripping pipe, an oil suction pipe, a plunger cavity, a supporting column, a lever, an adjusting rod and an adjusting nut. The lower portion of the plunger cavity is provided with a plunger capable of sliding up and down. An oil storage chamber is arranged on the upper portion of the plunger cavity. The plunger cavity and the adjusting rod are arranged on the two sides of the supporting column respectively. The two ends of the upper side of the lever abut against the plunger and the adjusting rod respectively. The oil suction pipe is communicated with the oil dripping pipe through the oil channel and a first one-way valve is arranged on the oil suction pipe. The vacuum hood is communicated with the oil storage chamber through oil holes. The oil outlet is communicated with the oil storage chamber through the oil channel and a second one-way valve is arranged on the oil outlet. A spring capable of making the plunger reciprocate is arranged between the plunger and the pump body. The adjusting nut is arranged between the adjusting rod and the pump body. The oil injection pump can achieve automatic oil injection and is high in working efficiency, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of mechanical lubrication, in particular to an oil injection pump. Background technique [0002] At present, the oil pumping unit in the oil field is lubricated with grease. During the repair or maintenance process of the pumping unit, the grease injection of the moving parts is generally manually operated with a grease gun. When adding butter to crank pins, maintenance workers have long used manual grease guns at high altitudes. First, the filling time is long and the work efficiency is low. Second, the viscosity of the butter is high and it is difficult to fill in winter. Workers work at heights for a long time, which is prone to safety accidents. Contents of the invention [0003] In order to solve the above problems, an embodiment of the present invention provides an oil injection pump, which can realize automatic oil injection. Described technical method is as follows: [0004] The embodiment of th...
