Product Outline

The CYJ series pumping unit is one kind of convention beam pumping unit, is the most common, an application scope broadest surface power equipment in field production oil .

The products conform to API Spec 11E " Specification for Pumping Units ", SY/T5044 " Beam Type Pumping unit" and other related standards.

 In addition to the production of conventional beam pumping unit, to meet energy-saving requirements of oil company, the company has developed : antiphase beam balanced pumping unit, double horse's head pumping unit, diameter and moment adjusting pumping unit, wheel type pumping unit and so on many kinds of energy saving pumping units.

Technical Features

1. Carry out the design using the modulation and the hypothesized technique of manufacture, optimize the product structure pattern, the spare parts have high level of “the standardization, the universalization, the seriation”. 

2. Strength of key parts is calculated with the finite element analysis， the property is stable, the reliability is high. 

3.The whole unit operating is simple, the maintenance is convenient, the service life is long.

4. The reducer uses the symmetrical divergence type double circular arc or the involute double helical gear transmission, seal is good, the noise is low, the revolution is steady, it is reliable and durable.

5. The beam uses box beam or I-beam structure, which has high strength, rigidity, large carrying capacity. 

6. The horse head is lateral rotary structure, when carrying out the workover, the horse head will rotary 90 °, so that the wellhead is being open position to facilitate operations.
