Pumping unit oil injection maintenance device

Abstract

The invention provides a pumping unit oil injection maintenance device. The pumping unit oil injection maintenance device comprises power source equipment, oil injection equipment, an oil bucket, an oil injection pipe and an oil gun. The power source equipment is composed of a storage battery and an inverter and connected with the oil injection equipment through a power line. The oil bucket is connected with the oil injection equipment through an oil conveying pipe. The oil gun is connected with the oil injection equipment through the oil injection pipe. The pumping unit oil injection maintenance device is suitable for maintaining pumping unit equipment in the environment that no regular power supply power source exists for field operation, and meanwhile, the pumping unit equipment maintaining quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of pumping units, and relates to an oil injection and maintenance device for pumping units. Background technique [0002] In oil field development, a large number of pumping units are used for production. Huge manpower and material resources are invested in the maintenance of pumping unit equipment in spring and autumn every year. The known maintenance methods of pumping unit equipment are as follows: 1. Using a grease gun or a medium-sized grease gun to manually add butter; 2. Using a manual grease gun but using a pressure barrel for refueling the grease gun; 3. Using a tractor with an air pump maintainance. [0003] The following problems exist in the maintenance of the above three methods: 1. The efficiency of manual butter filling is low, which is easy to cause pollution and waste more butter; 2. Although filling butter with a pressure barrel can reduce the waste of butter, the equipment is cumbersome ...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the maintenance of the above three methods: 1. The efficiency of manual butter filling is low, which is easy to cause pollution and waste more butter; 2. Although filling butter with a pressure barrel can reduce the waste of butter, the equipment is cumbersome and inconvenient to carry. The process of injecting grease is time-consuming and laborious; 3. The tractor with an air pump is simpler than the previous two methods, but the pressure of the air pump cannot meet the oil supply pressure of the grease gun, which may easily cause discontinuous oil supply to the grease gun and affect the progress. When the temperature is low, it is necessary to add engine oil 4. The high-altitude operation on the pumping unit during maintenance takes a long time, and the safety factor is low; 5. The maintenance takes a long time, resulting in long downtime of the oil well, affecting the oil production rate of the oil well and the long-term downtime. Uncertain failure rate of incoming oil wells increases
