Electric Cylinder Direct Drive Pumping Unit
- Sanjack Petro owns strong ability to research, design and manufacture jacks, and the annual output can reach 1000 sets. Our company has a welding workshop of 17,942 square meters, covering an area of 64,952 square meters, complete inspection and testing equipment, with more than 130 varieties of advanced production facilities.
- Electric cylinder direct drive beam pump is an innovative pumping unit developed by Sanjack Company, which has obtained national patent.
The electric cylinder direct drive pumping unit is a new type of beam balancing pumping unit, which directly drives the oil pump through the electric cylinder. The electric cylinder structure replaces the beam, connecting rod, crank and reducer box, reduces the transmission mechanism of the pumping unit, reduces the weight of the whole machine, and has high mechanical efficiency. Through the electronic control system, the stroke times of beam pumping unit can be adjusted stepless.
The inner pipe is fixed on the base of the pumping unit, the nut of the ball screw is fixed on the top of the inner pipe, and the ball screw is connected to the motor through an elastic coupling and is fixed on the outer pipe. The motor drives the ball screw to rotate, and the ball screw converts the rotating motion into up and down linear motion, so as to drive the beam to swing up and down through the outer tube to realize the oil return of the pumping unit.
2.Safety Rod Structure
When the equipment is in normal operation, the spring keeps the prepressure, supports the inner tube of the safety rod, and the outer tube of the safety rod follows the movement of the stepping beam; When stopped, the rod pin is safely inserted into the inner tube to lock the inner tube and outer tube, thus locking the pumping unit.
During the operation, stop at the designated location at the wellhead. Put a smooth rod clamp on the smooth rod and electric cylinder. When it stops working, the spring acts to move the tail of the beam.
When moving up, the donkey head load is removed so that the donkey head can give way to normal well operations
3. Balance Adjustment Structure
The balance adjustment of the pumping unit is realized by adjusting the distance between the tail counterweight and the center.
When working, move the tail balance block close to the electric cylinder, so that when there is no load, the electric cylinder can also drive the tail up and down balance movement.
4.Remote Control Principle
Remote monitoring is to achieve remote data collection and monitoring through the Internet of Things data transmission gateway.
The digital remote control system can be perfectly connected to the existing digital platform in the field or can be used independently as a remote digital platform.
