It is a pump that is immersed in a groundwater well for sucking and transporting water, and is widely used in farmland drainage and irrigation, industrial and mining enterprises, urban water supply and drainage, and sewage treatment, etc. Since the motor is simultaneously submerged in water, the structural requirements for the motor are more special than those of general motors.
[0003] Most of the existing deep well pump structures do not have an impact-proof structure. When the deep well pump is lowered into the deep well for use, the deep well pump is likely to collide with the inner wall of the deep well, resulting in damage to the deep well pump and seriously affecting the service life of the deep well pump. Summary of the Invention
[0004] The purpose of the utility model is to provide a wear-resistant and impact-proof deep well pump to solve the above problems in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A wear-resistant and impact-proof deep well pump, including a deep well pump main body, characterized in that a protection mechanism for protecting the outside of the deep well pump main body is arranged outside the deep well pump main body, and the protection mechanism includes two protection parts for protection, a plurality of buffer columns embedded on the protection parts and used for buffering and unloading force, and a plurality of connection components for connecting and fixing;
[0006] The two protection parts are arranged on the deep well pump main body in a relative structure, and the cross-section is arranged in a semi-circular arc structure. Both sides of the protection part are extended with connection parts;
[0007] The connection component includes an elastic connection strip and a connecting plate arranged at the end of the connection strip. The connection strip is fixedly connected to the connection part of the corresponding protection part;
[0008] The connecting plate is connected to the connection part of the corresponding protection part through a fastening bolt and can be radially fastened and adjusted. The connecting plate and the connection strip are integrally formed;
[0009] A plurality of stress strip holes for reducing collision stress are opened on the protection part;
[0010] The buffer columns are embedded through the side wall of the protection part and are sequentially arranged at intervals along the outer peripheral wall of the protection part.
[0011] In the above-mentioned wear-resistant and impact-resistant deep-well pump, several of the buffer columns can be made of impact-resistant rubber material. A hard coating for improving the impact resistance ability is provided on the surface of the protective part, and the protective part is made of alloy material.
[0012] In the above-mentioned wear-resistant and impact-resistant deep-well pump, the two protective parts are firmly connected by a connecting strip, a connecting plate, a connecting part and fastening bolts, and can be radially fastened and adjusted.
[0013] In the above-mentioned wear-resistant and impact-resistant deep-well pump, several of the stress strip holes are sequentially arranged at intervals on the protective part.
[0014] Compared with the prior art, the structure of the wear-resistant and impact-resistant deep-well pump of the present invention is simply designed. By using the structural design of the protection mechanism, the collision intensity between the outer peripheral wall of the deep-well pump body and the inner wall of the deep well is effectively reduced to the lowest level, preventing the problem of damage to the outer peripheral wall of the deep-well pump body caused by collision, and greatly extending the service life and service efficiency.
