How to realize the automatic lubrication of the beam pumping unit?
Centralized lubrication system refers to a system in which lubricating oil is accurately supplied to multiple lubrication points from a lubricating pump through some distributors, pipelines, and oil volume meters according to the set time, including delivery, distribution, adjustment, cooling, heating, and purification of multiple parts, the system can indicate and monitor parameters such as oil pressure, oil level, differential pressure, flow and oil temperature, and can perform fault detection and early warning.
The centralized lubrication system solves the shortcomings of traditional manual lubrication. It can provide lubrication at a fixed time, fixed point, and quantity during the operation of the machine, so as to minimize the wear of the parts and greatly reduce the use of lubricants. It is environmentally friendly and energy-saving. Effect. Centralized lubrication systems can reduce wear and tear on mechanical structures, extend maintenance intervals, and reduce equipment operating costs.
The centralized lubrication system can be divided into manual oil supply system and automatic oil supply system according to the oil supply method of the lubricating pump;
according to the lubrication method, it can be divided into intermittent oil supply system and continuous oil supply system; according to the transportation medium, it can be divided into grease centralized lubrication system and thin oil Centralized lubrication system;
according to the lubrication function, it can be divided into resistive centralized lubrication system and volumetric centralized lubrication system;
according to the degree of automation, it can be divided into ordinary automatic lubrication system and intelligent lubrication system. The centralized lubrication system is currently the most widely used lubrication system, and there are various types such as throttling, single-line, double-line, multi-line, and progressive.
The beam pumping unit is widely used in crude oil recovery and is an important part of artificial lift. The safe, reliable and long-term operation of beam pumping unit is related to oil well production and investors’ income.
In order to realize the stable operation of the beam pumping unit, the timing and quantitative lubrication of each moving part is indispensable. At present, the common lubrication method of beam pumping unit is that workers hold the oil gun to climb to the lubrication point and inject grease manually.
The main problems of this operation are as follows:
1. Shutdown operation is required, so crude oil production will be delayed.
2. Workers need to climb the upstream beam for climbing operation, there is a great potential safety hazard, and the labor intensity of workers is high.
3. The lubricating grease is not filled timely and is insufficient, which leads to the damage of the pumping unit and affects the service life of the equipment.
In view of these problems, Sanjack group has developed a new type of beam pumping unit automatic lubrication system, which can automatically inject grease into the middle seat bearing, tail seat bearing, and crank pin bearing of the pumping unit at fixed time and quantity, which perfectly solves this oilfield production problem.
The automatic lubrication system consists of the lubrication pump station, progressive distributor, pipeline and controller. As shown in the figure below:
The working principle of the automatic lubrication device is that the DC motor drives the gear to decelerate, the plunger makes reciprocating motion through the eccentric wheel, the lubricant enters the lubrication system through the oil outlet through the one-way valve through the oil suction and discharge process, and the lubricant is injected from the oil outlet one by one through the progressive distributor according to the specified sequence and sent to each lubrication point.
The process is fully automatic control and easy to operate. It can not only realize continuous oil injection but also inject oil regularly and quantitatively according to the need to fully lubricate the lubricating points.
The automatic lubrication system adopts a progressive distributor. According to the needs of different grease quantity of middle seat assembly, tailstock assembly, and left and right crank pin assembly, the flow rate is 2:2:1. The total displacement is 3ml/min, the middle seat assembly is 1ml/min, the tailstock assembly is 1ml/min, the left and right crank pin assemblies are 0.5ml/min, and the lubrication is not uneven.
The whole system adopts modular design and can be installed on all beam pumping units. It is easy to install, transport and operate.
Installation Process Description
This is the lubrication system of the pumping unit, with three bolts fixed on the base of the pumping unit. 1, 2, 3. Same three bolts are released when disassembling, 1, 2, 3. When installing this main lubrication line, just tighten this bolt. When disassembling, first loosen this position, and then pull out the mainline. The same principle when installing the mainline. First, feed it through the hole, then fix it and tighten it. The installation part is over.
Then the wiring part is connected from the upper hole and connected to the control cabinet.
This pipe is the main pipe and all the way up to the pumping unit. This pipe is the thickest one. That upper position is the distributor. When disassembling, just remove the distributor with two bolts.
Then, there are four lubrication points connected with four pipelines, the shortest one is located at the position of the middle seat assembly, the second shorter pipeline is connected to the tailstock of the pumping unit; then the third one is connected to the position of the crankpin; the last longest one is at the position of the crank pin of the otherside. The longest branch splits from there to reach here.
How to connect this joint, you need to take the wrench to remove it. When installing the joint, install the joint bolt crossover first, and then tighten the joint bolt. All joints are installed like this. Under normal circumstances, there will be a small buckle on the new joint. Now, I will show you the structure of the joint that has not been installed. The narrow mouth must be put in, not reversed. When the tube is inserted, it must reach the bottom, and then be tightened with a wrench.
