Abstract
The present invention relates to a processing method for a screw pump stator with isopachous rubber, which belongs to the technical field of mechanical oil production. The present invention provides a processing method for causing rubber layers of a screw pump stator to have uniform thickness. The present invention has the main method that a plurality of metal lamellae (2) of which the thickness is from 0.1 to 1mm have standard inner cavities of the screw pump stator, and the metal lamellae (2) are formed into helical lines and solidified in a metal shell (1). Rubber (3) is cast and sulfurized, and the screw pump stator with the isopachous rubber (3) is formed. The present invention has the advantages of high processing efficiency, high surface luster degree, unlimited length and thin and uniform rubber layers. Besides, the heat dispersion performance is improved when screw pumps work, etc., and the present invention is mainly applied to the oil production of the screw pumps with the isopachous wall thickness in the mechanical oil production.
Description
Technical field: the present invention relates to the mechanical oil recovery technical field, belong to screw pump stator processing method a kind of of rubber uniform thickness.
Background technique: at present, the processing of screw pump stator casts in rubber and forms in the steel pipe, and the internal surface of lining is the double helix curved surface, the rubber bushing became uneven.When this screw pump stator was worked, swell rubber was big and inhomogeneous under High Temperature High Pressure oil gas condition, and it is bad to dispel the heat, and causes the stator premature failure easily, has shortened the working life of screw bolt well.
Summary of the invention: the invention provides and can making the screw pump stator rubber layer is the screw pump stator processing method of a kind of rubber uniform thickness of uniform thickness.
The present invention is made up of following steps:
A. at first process the sheet metal with screw pump stator standard inner chamber of thickness 0.1mm-1mm, endoporus degree of finish reaches 6.3, and to the sheet metal quenching with Subsequent tempering, hardness reaches HB=200-250;
B. secondly these standard metal thin slices are sleeved on the identical core rod of dimensional parameters and form helix;
C. outside by bonding the helix of each sheet metal formation again, bonding force is solidificated in it in metal shell greater than 50Kn/m;
D. by after sandblast, cleaning, the oven dry, casting rubber also vulcanizes, and the injecting glue temperature is controlled at 90-110 ℃, and formation waits the screw pump stator of wall thickness rubber.
Compared with the prior art the present invention has following beneficial effect:
1, the screw pump stator of this rubber uniform thickness processing effect height, dimensional accuracy, any surface finish height, length is not limited.
2, the rubber layer of this screw pump stator is thin and even, the heat dispersion in the time of can improving screw pump work, and the heat ageing of slowing down rubber, can to some extent prolong than conventional pumps its working life.
3, thin and ability evenly thick rubber layer resistance to deformation in movement process is good, thereby single-stage pressure-bearing height; Can reduce the magnitude of interference between pump stage number and rotor under identical lifting lift condition, aspects such as its running moment of torsion and system effectiveness are better than the conventional screw pump, thereby improve the service behaviour of pump.
4, the screw pump stator swell rubber of uniform thickness, temperature expand evenly, can guarantee the molded lines of pump preferably, and the sealability of pump improves, and makes screw pump have better mechanical property in the running, helps keeping for a long time high pump efficiency, prolong the life cycle of pump.
Description of drawings: Fig. 1 is a cross-sectional structure schematic representation of the present invention;
Embodiment: provide embodiments of the invention below in conjunction with accompanying drawing:
When a. this method is used at the scene,, at first process the 45# steel thin slice 2 of thickness 1mm with standard inner chamber for the DGLB500-14 screw pump, stator throw of eccentric 4E=30mm, stator radius R=42mm, endoporus degree of finish is 6.3, and to 2 quenching with Subsequent tempering of 45# steel thin slice, hardness is HB=220;
B. secondly these standards 45# steel thin slice 2 is sleeved on the identical core rod of dimensional parameters and forms helix;
C. outside by bonding the helix of each 45# steel thin slice 2 formation again, bonding force is 56Kn/m, and it is solidificated in the 45# metal shell 1;
D. by after sandblast, cleaning, the oven dry, casting rubber 3 also vulcanizes, and the injecting glue temperature is 100 ℃, and formation waits the screw pump stator of wall thickness rubber 3.
