How to Install the Long Stroke Pumping Unit

Except the electrical control system needs to be installed on the production site, the other transmission, traction mechanism and components are installed before leaving the factory. The machine base and machine body are dismantled during transportation. Machine base needs to be adjusted on site and connected to machine body after fixation. Then, adjust the center of the traction belt and the sucker rod aligning.

(1) The cement foundation shall be tampered and installed according to the requirements of the foundation drawings, and it require solid and level.

(2) Fixing the cement foundation which made of cement and reinforced concrete, on the building foundation. The level of the upper plane of the cement base shall not exceed 5 mm, height equal to wellhead flange. And it shall not be greater than 10mm with the wellhead center.

(3) After the cement foundation is installed, the lower body can be vertically suspended on the cement base. Pay attention to prevent the screw part of the foundation bolt from being damaged when lifting the base. After the lower body of the whole machine is installed, it can connect with the upper body.

(4) Lift the rod up and adjust the anti-impulse distance by using operation machine, then fix it on the wellhead with square clips.

(5) Confirm the transmission system electronically correct after the electrical control box energized.

(6) In the condition of the traction belt inside the tower of pumping unit is not connected with the counterweight box, point the powertrain to adjust the external traction belt align with the center of the wellhead rod, deviation shall not exceed 10mm. Then tighten the nuts of all foot bolts. After that, point the powertrain to move the external traction belt up to the top dead point. Then connect the internal counterweight box with the joint of the internal traction belt by using the internal rope hanger.

(7) After confirming that the two ends of the traction belt are connected correctly and the stroke and stroke time are correct, it can be ran at low speed to check whether the connection between traction belt and rod of pumping unit and internal counterweight box are in correct state. If there is any difference, adjust the connecting nuts at both ends of the traction belt.

(8) After the confirmation of the test operation, it is necessary to adjust the stroke speed and length of the rod according to the well condition and the requirements of oil production technology, and then the pumping unit will enter normal operation.
