Good corrosion resistant diaphragm pump development tendency

10 - 24

anti-corrosive diaphragm pump development momentum positive corrosion diaphragm pump is the main type of actuator, by accepting unit outputs a control signal, modulation from engine operation to change fluid flow. Corrosion resisting diaphragm pump and valve general, the executing agency. Corrosion resisting diaphragm pump adopts compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, all can be smoked light. Corrosion resisting diaphragm pump as the name suggests is a diaphragm pump with corrosion resistance, corrosion resistance diaphragm pump is mainly used for conveying corrosive liquid. Corrosive liquid transportation of the most widely used for fluorine plastic material corrosion resistant, corrosion resistant diaphragm pump diaphragm pump has the advantages of superior corrosion resistance range. The whole process of diaphragm pump is a suction and discharge process. Under the power driven by the drive mechanism to promote the piston reciprocating motion, Piston stroke by adjusting mechanism to change) , back and forth by the hydraulic oil push diaphragm incited doing work. When the piston moves back, diaphragm gradually recession, corrosion resistant diaphragm pump pump cavity volume increases gradually, the pressure gradually reduced, below the inlet pipe pressure when the inlet valve opens, media into the pump chamber, the piston reaches the check point, the media is full of pump cavity, the inlet valve to close. Suction process is complete, start the process. As the piston to move forward, diaphragm, corrosion resistant diaphragm pump pump cavity volume became smaller, the pressure gradually increases, the outlet valve is opened, the media gradually discharge pump chamber, the piston reaches the check point, the outlet valve shut down due to gravity and spring force, the end of the discharge process, pump and begin a new suction process. Such continuous inhalation and discharged liquid, complete the purpose of conveying medium. Corrosion resisting diaphragm pump is a kind of changes caused by deformation of diaphragm reciprocating displacement volume pump, corrosion-resistant diaphragm pump working principle is akin to plunger water pump, because of the characteristic of the working principle of the diaphragm pump, diaphragm water pump has the following characteristics: (so corrosion resistance 1) Corrosion resisting diaphragm pump does not overheat: compressed air power, when the exhaust is an endothermic process, pneumatic pump work when the temperature is lower, no harmful gas discharge. （ 2) Can contain particles of liquid: for displacement and import work for ball valve, so it is not easy to be blocked. （ 3) Low shear force of material: how is sucked into how spit out at work, so minimal agitation of the material, corrosion resistant diaphragm pump is suitable for the unstable material conveying ( 4) Flow adjustable, can be in material with throttle valve to regulate traffic. （ 5) Empty can run, but there is no danger. （ 6) Corrosion resisting diaphragm pump can be diving. （ 7) Can conveying fluid is very broad, from low to high viscosity, viscosity sticky from corrosion. （ 8) No complicated control system, no cables, fuses, etc. （ 9) Small volume, light weight, easy to move. Corrosion resistance of the diaphragm pump structure refers to the number of single and double effect of piston, piston cylinder, the piston of vertical and horizontal. Corrosion diaphragm pump with two-cylinder double-acting, triplex single acting horizontal structure, multi-cylinder single-acting vertical structure, commonly used for two-cylinder double-acting, triplex single acting horizontal structure. Two-cylinder double-acting, triplex single acting diaphragm water pump, corrosion-resistant diaphragm pump are from the drive system, the power end, hydraulic, hydraulic auxiliary system, front-rear compensation system, the control system. Driving system consists of motor, reducer, Or belt) Composition. Power side is mainly refers to the crank connecting rod mechanism, corrosion resistant diaphragm pump function is to convert rotary motion into linear motion, power piston can. Contains power side has a gear drive and gearless driving two structures. Hydraulic end refers to complete the liquid conveying part, by the piston cylinder, the diaphragm chamber, valve box, etc. Corrosion resistance of the diaphragm pump is instantaneous flow over time according to the relation of triangle function, because the flow nonuniformity, the pump suction and discharge pressure fluctuations, affecting the service life of pump and pipeline, in order to reduce pressure fluctuation, and must be set in and out of material compensation device. Corrosion resistant front-rear compensation system adopts the air chamber and the diaphragm pump for flow compensation for cylindrical pressure compensation, to ensure uniform flow, to guarantee the stability of inlet and discharge pressure.
