Abstract

The invention provides a PTFE screw pump stator molding clamp and technology, which are used for solving the problem that a screw pump stator in the prior art cannot meet the requirements of media. The PTFE screw pump stator molding clamp comprises a pressing plate, a charging barrel, a stator mold core, a bottom mold plate and a bolt, wherein the bolt comprises a mold core fixing bolt and a locking bolt; the pressing plate is T-shaped and comprises a head part and an end part; a through hole which penetrates through the head part and the end part is formed in the pressing plate; the pressing plate is bilaterally symmetrical relative to the through hole; a cylindrical cavity is formed in the charging barrel; the end part is inserted into the cylindrical cavity; one end of the stator mold core is inserted into the through hole, and the other end of the stator mold core is fixed on the bottom mold plate; the bottom mold plate is fixedly connected with the charging barrel. The molding technology provided by the invention is simple, and the disadvantage that a screw pump adopting a rubber stator cannot transfer certain special media is overcome.

Description

technical field [0001] The invention relates to a screw pump stator, in particular to a PTFE screw pump stator forming fixture and a PTFE screw pump stator forming process. Background technique [0002] The screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and the screw to deliver or pressurize the liquid. [0003] The stator of the screw pump is an important part that is easily damaged in the screw pump. When the screw pump transports special media, the ordinary rubber stator cannot meet the requirements of the medium (such as strong corrosive media); although PTFE is known as the king of plastics, it has difficulties in processing. Defects, especially the irregular shape of the screw stator, cannot be solved by general machining methods. [0004] Therefore, it is necessary to develop a new PTFE screw pump stator forming fixture and PTFE screw pump stator forming process to make up for the above defects. ...
