Abstract
The utility model relates to a long stroke hydraulic oil pumping machine used for a non-automatic spraying well. The long stroke hydraulic oil pumping machine used for a non-automatic spraying well is composed of a hydraulic station, a balance cylinder, a multiplication type lifting cylinder, a movable pulley, a bracket, and a steel cable. Structural forms which are separately arranged are adopted by the balance cylinder and the multiplication type lifting cylinder. The utility model has the advantages of simple structure, small form size, light weight, low working height, low manufacturing cost, convenient installation and maintenance, long working stroke (can achieve 6 meters), no oil leakage, strong integral machine working reliability, etc.
Description
The utility model relates to a kind of long stroke hydraulic pumping unit that nonflowing well recovers the oil that is used for, and it belongs to the oil recovery technique field.
At present, nonflowing well adopts beam pumping unit mostly, is applicable to that the chain type oil pump that long stroke recovers the oil also drops into practical application gradually.But the structural feature of beam pumping unit has determined it not develop to long stroke; It is 5 meters chain type oil pump that Shengli Oil Field is developed a kind of stroke, bulky, nearly 20 tons of weight, and about 150,000 yuan of prices, installation and transportation are very inconvenient.Also has a kind of no bracket hydraulic pumping unit, its compensating cylinder and lifting cylinder are concatenated into one, the shortcoming of this structure is a complete machine working depth height, poor work stability, lifting cylinder operating mode poor (can produce leakage of oil), mounting process requires harsh, and the cascaded structure form of two cylinders has limited the stroke of pumping unit.
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned pumping unit, provide a kind of simple and reasonable, boundary dimension is little, in light weight, cost is low, installation and maintenance long stroke hydraulic pumping unit easily, to satisfy the needs of the long stroke low jig frequency oil production technology of rising.
The utility model is made up of hydraulic station 1, compensating cylinder 2, double type elevating ram 3, movable pulley 4, support 5, cable wire 6,1 of hydraulic station is made up of control integrated valve block 7, accumulator 8, motor 9, high-pressure plunger pump 10, except that motor, it is each other by pipeline connection.Motor links to each other with high-pressure plunger pump.Said compensating cylinder 2 and double type elevating ram 3 apart arrangement, i.e. double type lifting cylinder 3 is vertically fixed on by the well head by support 5; 2 of compensating cylinders are fixed on the hydraulic station 1, it has four hydraulic fluid ports, middle two hydraulic fluid ports are communicated with the control integrated valve block in the hydraulic station 17 by pipeline, one of two hydraulic fluid port at two ends are communicated with accumulator 8 and control integrated valve block 7 in the hydraulic station 1 by the road simultaneously, and another hydraulic fluid port is communicated with double type elevating ram 3 by pipeline.Movable pulley 4 is installed on the support 5, and cable wire 6 one ends are fixed on the base of support 5, and the other end is walked around movable pulley 4 and connected with load.
The long stroke hydraulic pumping unit of Gou Chenging thus; Overcome the shortcoming of above-mentioned pumping unit fully, satisfied simple and reasonable, boundary dimension is little, in light weight, cost is low, installation and maintenance requirement easily, because it has adopted two cylinder separated structures forms, its stroke is greatly increased, the complete machine working depth reduces greatly, its maximum stroke can reach 6 meters, 8 meters of critical altitudes, 12 tons of maximum loads, about 5 tons of gross weight, every about 100,000 yuan of prices, and also the lifting cylinder can leakage of oil, improve operating mode, improved the functional reliability of complete machine.
Narrate most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 always schemes for structure of the present utility model
Behind the starting electrical machinery 9, high-pressure plunger pump 10 is transported to accumulator 8 by control integrated valve block 7 with pressure oil, after arriving setting pressure, control integrated valve block 7 automaticallyes switch immediately pressure oil is input to compensating cylinder oil pocket 13, simultaneously, accumulator begins pressure oil is released into compensating cylinder oil pocket 11, and oil pocket 11 and 13 pressure oil is driven plunger 15 simultaneously, the oil pressure of oil pocket 14 is gone into the cavity of resorption of double type elevating ram 3, to promote load.When rising to setting height, control integrated valve block 7 automaticallyes switch, pressure oil input oil pocket 12 with oil pump 10 outputs, simultaneously, because load action of gravity, the oil of elevating ram 3 cavity of resorptions is pressed into oil pocket 14 by plug cock 16, oil pocket 14 will produce certain back pressure, and like this, oil pocket 12 and 14 pressure oil driven plunger 15 are gone into accumulator 8 with the oil pressure of oil pocket 11, with stored energy, at this moment, elevating ram descends, when dropping to desired location, the control integrated valve block automaticallyes switch immediately, begins the repetition lifting process again.
