Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-5, an integrated high-strength elliptical head end cover comprises a chassis 1, wherein a head 2 protruding outwards is arranged on the surface of the chassis 1, the waist of the head 2 extends in an arc shape along the circumferential direction to be integrally connected with the chassis, a boss 3 protruding along the plane direction of the head 2 is arranged at the top of the head 2, a connecting column 4 connecting the head 2 and the chassis 1 is arranged at the bottom of the boss 3, a plurality of fixing lugs 5 are uniformly distributed at the waist of the head 2, the adjacent fixing lugs 5 are consistent with the included angle between the boss 3, the waist of the fixing lugs 5 is attached to the waist of the head 2, the bottom of the fixing lugs extends to the surface of the chassis 1, the fixing lugs 5 and the boss 3 are distributed on the head 2 in a staggered manner, a through hole 6 penetrating through the chassis 1 is formed in the middle part of the surface of the head 2, a step ring 7 extending to the outside of the disk surface is arranged at the other end surface of the chassis 1, step circle 7 and chassis 1 junction are equipped with the sunken card platform 8 of center of a plate, card platform 8 is to locating step circle 7 upper and lower surfaces, card platform 8 and pump body inner tube looks joint.

The end socket 2, the chassis 1 and the step ring 7 are formed by one-step casting. Through with head, chassis and step circle one-time casting shaping, improve whole crushing resistance, through the mould casting, reduce the manufacturing degree of difficulty simultaneously.

The inner wall of the seal head 2 extends to the end face of the bottom of the step ring 7 in an arc mode, and a gap is reserved between the inner wall of the seal head 2 and the bottom of the clamping table 8. A gap is reserved between the inner wall of the seal head 2 and the clamping table 8, so that a buffer space is reserved when the clamping table 8 is connected with the inner cylinder of the pump body and is subjected to impact force.
