Product introduction

The main technical characteristics of our R & D and production of diaphragm pulp pump is using a special diaphragm piston pump piston cylinder all originals and conveying medium to isolate the diaphragm pulp pump capable of transporting high tempered, corrosive particles in the medium. Is the main technical characteristics to solve the wear problems of large parts of the cylinder piston, piston, piston rod, piston, so as to obtain the equipment run time lengthened, less wearing parts, reduce the operation cost ideal goal. Diaphragm pulp pump belongs to a volumetric non leakage pump, suitable for conveying the solid-liquid two-phase medium. The pump has been in the metallurgical, chemical, mining, nonferrous metals, power plants, sewage treatment plants and other fields to achieve successful application.

Diaphragm pulp pump advanced technology features, the real implementation of the concept of green consumption and environmental protection. The diaphragm pulp pump safety, reliability, continuous operation rate and running cost of key technical indicators has obviously better than oil isolation pump, water washing pump and water isolation pump, as a high flow, high pressure conveying toxic, corrosive medium and containing solid granules medium of the ideal of a new generation of reciprocating pump, and will be more widely used.

Structure profile

Diaphragm pulp pump power end with a set of gear reducer, plus external pulley or reducer deceleration, the pump speed dropped to 40 ~ 90RPM; pump can be selected according to different medium conveying speed; motor through a gear driven crank and connecting rod mechanism, rotary motion change into linear motion, driven by the crosshead and piston rod and the piston for reciprocating motion.

The pump hydraulic end is a cross head to drive the piston to do reciprocating motion through the piston rod, the piston motion drives the hydraulic medium to make the diaphragm to make the concave and convex motion. In the suction stroke, diaphragm moves backwards, inhalation valve is opened, a discharge valve is closed, the transmission medium into the pump cavity; during the discharge stroke, the diaphragm moves forward, inhalation valve is closed, the discharge valve is opened, discharging and conveying medium.

Technical characteristics

Developed by our company "automatic oil filling system" cutting mechanical diaphragm type and, truly realize the diaphragm stroke position control and pressure control, can prevent membrane damage occurred in the ultra stroke, greatly improve the service life of the diaphragm.

The wear resistance and the fatigue life of the special materials, which are developed by our company, have reached the ideal cycle of industrial equipment. Diaphragm can be used in accordance with the need for the delivery of fluid bowl diaphragm or plate diaphragm. The control valve of the bowl type diaphragm is connected with the diaphragm, and the diaphragm is connected with the diaphragm, and the diaphragm is made into a bowl type to enable the diaphragm to be subjected to the bending stress of the diaphragm in a reciprocating motion. The reciprocating stroke of the diaphragm can be larger, and the diameter of the diaphragm can be reduced. Flat diaphragm made into double diaphragm structure.
