Zusammenfassung:The invention relates to the technical field of pump bodies, in particular to a pump body capable of avoiding the cavitation problem, which comprises a shell, a water outlet pipe and a water inlet pipe, a box body is mounted on the upper part of the water inlet pipe, a liquid leakage hole is formed in the upper part of the water inlet pipe, a limiting block is inserted into the inner side of the liquid leakage hole, and an adjusting structure is arranged on the inner side of the limiting block; the bottom of the adjusting structure is connected with the limiting block; the adjusting structure comprises a lifting structure and positioning structures arranged on the two sides of the interior of the box body, and the lifting structure is connected between the positioning structures. In research and development, it is found that the cavitation problem has a large relation with the pressure intensity in the pump body, meanwhile, according to the formula P = rhogh, g is the gravitational acceleration, h is the dept
