Description
Technical Field
The invention relates to the technical field of grinding processing of spiral surfaces of workpieces, in particular to a grinding device for surface treatment of a rotor of a submersible screw pump.
Background
The oil pump is a downhole device driven by the pumping unit to lift crude oil in the well to the ground. The common oil pump mainly comprises four parts of a pump barrel, a suction valve, a piston and a discharge valve. According to the fixation mode of the oil-well pump under the well, the oil-well pump can be divided into a tube pump and a rod pump. The rod-type oil pump is also called as insertion pump, in which the fixed rod-type pump is characterized by that it has two working cylinders, its upper end is equipped with cone seat and jump ring, when the pump is lowered, the external working cylinder is first lowered into the well along with oil pipe, then the internal working cylinder equipped with lining and piston is connected with lower end of pumping rod, lowered into external working cylinder and fixed by jump ring.
Screw oil pump belongs to a kind of rod pump, the screw pump is a new type pump which works according to the principle of rotary engagement positive displacement, its main working components are eccentric screw (rotor) and fixed bush (stator). During operation, through the mutual matching of the rotor and the stator, a plurality of sealing chambers are formed on the surface of the rotor and the inner surface of the stator rubber bushing along the whole length of the screw pump; along with the rotation of the rotor, a sealing cavity is formed between the rotor at the suction end and the inner surface of the stator rubber bushing, and the sealing cavity is pushed towards the discharge end, finally, the sealing cavity disappears at the discharge end, and oil is sucked under the action of pressure difference at the suction end and pushed to the discharge end by the suction end.
The working principle of the screw pump requires high matching degree between the rotor and the stator to ensure the sealing performance of a cavity formed between the surface of the rotor and the inner surface of the stator rubber bushing, so that the screw pump rotor is subjected to multiple processing procedures such as finish turning, spiral grinding and surface chromium plating and the like, and then is subjected to additional surface grinding processing for one time, thereby eliminating the processing defects of the surface of the screw pump rotor and improving the surface precision.
In the actual processing process, due to the special appearance of the screw pump rotor, when the screw pump rotor is ground by adopting the existing process or processing device, the following problems often occur:
1. the grinding clamping of the spiral rotor is inconvenient, and in order to ensure complete coverage of a grinding range in the grinding process, the rotor needs to be detached and installed for many times to change the grinding position, so that the grinding efficiency is low.
2. It is difficult to achieve dead angle free grinding of the rotor surface. Specifically, the outer surface of the rotor of the screw pump is an uneven spiral surface, the spiral angles of the rotors with different specifications are different, when the spiral surface of the rotor is ground by adopting grinding tools such as a grinding wheel and the like, a plurality of grinding dead angles which are difficult to eliminate exist, and because the rotor has a certain length, when the rotor is continuously ground, the grinding dead angles are gradually increased, the surface grinding quality is seriously affected, and when the grinding wheel is adopted for grinding, the contact area between the grinding wheel and the surface of the rotor is small, the area of single grinding is limited, and the integral grinding efficiency is greatly reduced.
3. The clamping loading and unloading of the rotor are inconvenient. Specifically, the rotor of the screw pump is a steel rod piece with a certain length and weight, the labor intensity of a manual butt joint feeding mode is high, the tail end of the rotor is easy to collide with grinding equipment in the feeding and discharging process, damage is caused, and the product quality is reduced.
