Good quality API spec 11E belt oil pump jack for sale

API BELT TOWER PUMPING UNIT

Belt tower pumping unit is specially designed to solve the inherent defects of beam pumping unit.
It has the advantages of energy-saving, convenient parameter adjustment and long stroke

* Beam pumping unit is the most widely used mechanical equipment in oil field, but it has many inherent defects. Such as high energy consumption, low mechanical efficiency, not easy to achieve a long stroke.

* Non-beam pumping unit is developed to solve the inherent defects of beam pumping unit. It is characterized by high degree of automation, intelligent parameter adjustment, low energy consumption and low noise.

1. Main Structure:

1) Frame System
It is composed of an upper platform, a main frame, front and rear supports, a large base, and a cement foundation composed of a steel structure.Support the upper platform to ensure the maximum stroke of the smooth sucker rod.

2)Power Unit
Installed on the upper platform, including: motor, driving wheels, guide wheels, couplings, reducers, automatic brakes, manual brakes, etc., are the executive parts of the pumping unit to transmit torque.

3) Counterweight System
It is composed of counterweight box (main and auxiliary), slide rail and pulley block.
Precisely adjust the weight of the counterweight box and the balance of the oil sucker polished rod end to make the machine run smoothly and save energy.

4) Control System
It is mainly composed of motor, SR controller, programmable logic controller (PLC), and various operation buttons.It is a stepless speed regulation system, which can realize the automatic and manual control modes and fault display of the equipment.

5) Safety System
It is composed of upper and lower (double) limit switches, proximity switches, automatic (manual) brake devices, lightning arresters, and counterweight box buffer pits. Ensure the safe operation of equipment.

6) Auxiliary system
Load sensor, liquid level detector, monitoring, acquisition system, etc.

7)Security system
Multiple Security Protection Automatic alarm and brake for overload, overspeed and lack of phase.
Loss of Load Protection Sudden rod breakage and other faults cause loss of load, and there is brake protection.
