pumping unit. pumping unit The beam pumping unit has a better balance and eliminate,the negative torque because a rigid lower deviated beam balance . The beam pumping unit endows some features of reliable performance,simple structure,easy operation and maintenance etc .the technical parameters accord with industry standard for the people's Republic of SY/T5044 beam pumping unit, and the American Petroleum Institute API 11E standard ,the tecnology is mature . 1).The overall struture is reasonable,steady work ,small noise ,easy to maintain and operate , 2).The beam adopts box or L-steel struture ,which endows high strength,rigid,large carrying capacity . 3).The reducer adopts lambdoidal involute circular tooth gear,high-precision machining ,large carrying capacity ,long lifetime . pumping unit 1.Walking beam compound balaned pumping units is a enginery saving new type designed on the basis of conventional pumping unit ,The difference of structure is : add a balance device on the tail of walking beam and put on some balance block, so as to form special counter balance with the crank balance weight ,it reduce the peak output net torque of gear reducer and increase the valley ,so the fluturation is decrease ,hence ,the balance effect is improved , 2.pumping unit This series has the merit as following : simple structure ,easy to start ,working smooth ,small additional dynamic load,long stroke,low energy consumption,working reliable,easy to operation and maintance and high combined effciency,It is an ideal and advanced surface pump , 3.pumping unit Double horse head pumping unit is developed on the basis of conventional pumping unit .It is not only has the same merit with conventional pumping unit of simple structure,working reliable and easy to maintan ,but also has the advantage of working smooth ,small additonal dynamic load,long stroke ,low energy consumption and high combined efficiency.It is an ideal and addvaned surface pump .Double horse head pumping unit fit for exploiting crude oil of of middle or low viscocity and fit for high water content crude oil ,for the horizontal well ,slop mine and ropy crude oil which are hard to exploit in normal working condition ,you can enlarge the type of gear reduce and motor ,So as to reduce the stroke frequency for exploitation , pumping unit Type API spec 11ERated suspension center loadReducer TorqueStroke Stroke FrequencyMotor Power Machine QualityCYJ3-0.75-2.8HY 25-64-30 30 2.8 0.75 9,14 3.2 4.5 CYJ3-1.2-2.8HY 25-64-48 30 2.8 1.2 6,9,12 4.0 5.2 CYJ3-1.5-4.5HY 40-64-60 30 4.5 1.5 9,14 4.5 5.5 CYJ5-1.8-13HY 114-107-72 50 13 1.8 6,9,12 11 7.0 CYJ10-3-37HY 320-213-120 100 37 3.0,2.5,2.1 6,9,12 30 18.0 CYJ12-4.8-73HF 640-256-192 120 73 4.8,4.2,3.6 5,7,9 45 29.0 CYJ14-4.8-73HF 640-305-192 140 73 4.8,4.2,3.6 5,7,9 55 31.7
