AI Technical Summary
Technical Problem
Existing piston diaphragm pumps can damage the diaphragm when delivering high-temperature liquids.
Method used
A liquid variable capacity mechanical pump is designed, using a heat insulation plate and a adjustment mechanism. Through the circulation of external liquid and coolant, the temperature of the adjustment liquid is cooled to prevent the diaphragm from being damaged by heat.
Benefits of technology
It effectively prevents the diaphragm from being damaged by high temperature and ensures the normal operation of the pump under high temperature conditions.

Abstract
The invention relates to the technical field of mechanical pumps, in particular to a liquid variable-volume mechanical pump. A liquid variable-volume mechanical pump comprises a pump body, a diaphragm, an adjusting mechanism and a driving mechanism. A first mounting cavity is formed in the pump body, a heat insulation plate is arranged in the first mounting cavity, and the heat insulation plate and the diaphragm define a liquid flow cavity, an adjusting cavity and a cooling cavity in the first mounting cavity. External liquid passes through the liquid flow cavity, adjusting liquid is arranged in the adjusting cavity, and cooling liquid is arranged in the cooling cavity. Through the arranged adjusting mechanism, flowing external liquid is introduced into the liquid flow cavity, the adjusting liquid in the adjusting cavity receives heat transmitted by the external liquid through the heat insulation plate, part of cooling liquid enters the corrugated pipe, the cooling liquid in the corrugated pipe cools the adjusting liquid in the adjusting cavity, and therefore the diaphragm is prevented from being damaged after being heated. The invention provides a liquid variable-volume mechanical pump to solve the problem that a diaphragm is damaged when an existing piston diaphragm pump conveys high-temperature liquid.
