Corrugated pipe extruded hydraulic peristaltic pump

Abstract

The invention provides a corrugated pipe extruded hydraulic peristaltic pump. The corrugated pipe extruded hydraulic peristaltic pump comprises a cylinder block, a tubular diaphragm, an outlet pipe, awater outlet valve set, an inlet pipe, an inlet valve set, a corrugated pipe, a push rod and a driving unit, wherein the cylinder block is provided with a main flow channel, an airtight cavity and apassage, and the passage communicates with the main flow channel and the airtight cavity; the tubular diaphragm is arranged in the main flow channel, and a gap exists between the outer sidewall of thetubular diaphragm and the inner sidewall of the main flow channel; the outlet pipe and the water outlet valve set are arranged at one end of the tubular diaphragm; the inlet pipe and the inlet valveset are arranged at the other end of the tubular diaphragm; the corrugated pipe is located in the airtight cavity, one end of the corrugated pipe communicates with the passage and is in sealing connection with the inner wall of the cavity, and the other end of the corrugated pipe is sealed; one end of the push rod is connected with the other end of the corrugated pipe; the driving unit is connected with the other end of the push rod and used for driving the push rod to do reciprocating motion in the axial direction. Through the corrugated pipe extruded hydraulic peristaltic pump, the problemsthat a diaphragm of a diaphragm pump deforms only in one direction and accordingly potential leakage is caused in the prior art are solved.

Description

Technical field [0001] The invention relates to the technical field of fluid pumps, in particular to a hydraulic peristaltic pump in the form of a bellows extrusion. Background technique [0002] The non-leakage positive displacement pump is a machine that can safely transport dangerous fluids or precious liquids. Because the non-leakage pump is a static seal, the variable seal is a static seal, which effectively solves the problem of leakage and lubrication. Therefore, it can be widely used in the transportation of corrosive media in chemical production, the treatment of chlorinated water and the acid addition process, the transportation of electrolyte in non-ferrous metal smelting, the pickling process in automobile manufacturing, and the pharmaceutical, petroleum, electric power, electroplating, and dyestuffs , Pesticide, paper, food, textile and many other industries. [0003] Nowadays, there are mainly two types of leak-free positive displacement pumps on the market. One is a...
