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.

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.

6). 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
