The history of oil extraction has been going on for a hundred years. In the early days, oil extraction wells were very shallow and were drawn with buckets. Later, the depth of the wells increased, the oil extraction method is gradually complex, divided into two categories of self-spraying oil extraction method and artificial lifting oil extraction method, the latter has two kinds of gas lift oil extraction method and pumping oil extraction method. Among them, the pumping extraction method is the method of pumping the liquid produced in the oil reservoir to the surface by lowering the pump in the oil well.
The pumping machine is mainly to change the circular motion of the power machine (usually an electric motor) into reciprocating linear motion, driving the pumping rod and pump. At present, most of the oil wells in the world use mechanical oil recovery method - rod pumping oil extractor.
In this equipment, the touch screen plays a very important role, it communicates with the PLC, which reads the speed, voltage, current, torque, output power and other parameters from the inverter, and these parameters are finally calculated and processed by the PLC or directly displayed on the main interface of the touch screen. Workers control the oil recovery machine equipment through the touch screen interface.
The benefits of touch screen application in oil recovery equipment?
1. Convenient maintenance: the control part of traditional equipment uses more buttons, indicators, etc., and more hardware wiring. After the use of touch screen, the combination of PLC and touch screen, save a lot of buttons, switches, relays and other hard components, reducing the hardware wiring, eliminating a large number of hidden trouble points. Convenient installation, easy to maintain.
2. Intuitive display: touch screen can be the entire system of field data centralised display, easy to observe, automatic recording, intelligent and intuitive. Such as equipment power consumption display, abandon the way to add a meter, but the way to read the parameters of the inverter output power calculated, and displayed on the touch screen and storage. At the same time, the touch screen can also be programmed to record the total energy consumption of the equipment in a certain period of time, which is conducive to the relevant departments to count the equipment and observation.
