Description
Technical field
The utility model relates to a kind of oil field equipment, is specifically related to a kind of beam pumping unit.
Background technology
In the vast oil field oil-producing region of China, have to be that much the low energy of hyposmosis, stripper well, the overwhelming majority will lean on water flooding regime to press oil to go into well, elevate oil by oil pumper from underground.Changing oil, change oil with electricity with water is the basic skills that present China recovers the oil.Wherein, power consumption has accounted for sizable ratio in the cost of oil production of China.How to improve oil recovery efficiency, improve output, reduce power consumption and extraction liquid energy expenditure per ton ratio, and oil pumper recovered energy processing mode, environment for use and underground operating mode, the control mode of oil pumper and problems such as easy to adjust become the common focus of inquiring into of oil field energy saving equipment producer.
The utility model content
Technical problem to be solved in the utility model provides a kind of beam pumping unit esy to use, safe and reliable.
The utility model is achieved through the following technical solutions:
A kind of beam pumping unit of the present utility model, comprise base, reduction box, support, crank, motor, belt pulley and walking beam, described support is installed in the base left end, described cantilever tip is hinged with walking beam, described reduction box is installed on the base, described belt pulley is installed on the power shaft of reduction box, on the output shaft of described reduction box crank is installed, described crank one end is connected with balance weight, and described crank and balance weight joint also are hinged with a connecting rod, and the described connecting rod other end is hinged on walking beam lower-left end, described walking beam right-hand member is equipped with horse head, described horse head is provided with polished rod eye, and described motor is installed in the base left end, and described motor is connected with frequency converter.
Further, on the base in described motor left side brake is installed, and described brake is connected with motor.
Further, be connected with belt between described motor output shaft and the belt pulley.
Further, described balance weight center and crank end are hinged.
Operating principle of the present utility model and beneficial effect are: the utility model is a kind of quadric chain of distortion, and its complete machine structure characteristics are as a balance, and an end is oil pumping load, and the other end is counterweight load.For support, if the moment of torsion of oil pumping load and balancing load formation equates or variation is consistent, with very little power oil pumper is worked uninterruptedly so; In the early stage in the oil well, because oil well is just exploited, oil reserve is big, for improving the oil recovery effect, we can improve the stroke frequency of oil pumper, allow frequency converter move to 65Hz, frequency improves 1/3, and correspondingly motor speed has improved 30%, its oil production is corresponding improve also, in, during the later stage oil well is gathered, because the stoste reserves reduce in the well, the feed flow deficiency, motor is if still adopt power frequency operation, certainly will waste electric energy, cause unnecessary loss, thereby adopt the stroke frequency of adjusting oil pumper and select fast slow control mode down for use, generally with the FREQUENCY CONTROL of frequency converter between 35～45Hz, the motor mean speed descends 20% like this, and the general load of oil production equipment is lighter in addition, and its power saving rate can reach 30%.
