Abstract

The present invention discloses a device of pump, and is aimed at providing a hydraulic oil cavity quick air-releasing structure of metering pump. It includes two portions of hydraulic oil loop connecting plate assembly and air-releasing oil cup assembly. The hydraulic oil loop connecting plate assembly includes connecting plate with oil way channel, three-way screw and air-releasing screw; and the air-releasing oil cup assembly includes oil cup and hollow housing screw connected with the oil cup. Said housing screw has external screw-thread identical to that of air-releasing screw, can be screw-connected with top of three-way screw.

Description

technical field [0001] The invention relates to a pump arrangement. More specifically, the invention relates to a rapid emptying structure of a metering pump hydraulic oil chamber. Background technique [0002] Metering pumps are widely used in chemical industry, oil refining, pharmaceutical, electric power, paper making, food, urban water supply, industrial water, environmental protection and other occasions. Metering pump is a kind of positive displacement pump, which is divided into two categories: plunger pump and diaphragm pump. Diaphragm pump can be subdivided into hydraulic diaphragm pump and mechanical diaphragm pump. Hydraulic diaphragm pumps can be divided into metal diaphragm metering pumps and non-metallic diaphragm metering pumps due to different diaphragm materials. At present, the products used in domestic and foreign markets are mainly non-metallic diaphragm metering pumps. The main features of the metering pump are accurate metering, high output pressure, ...
