The pneumatic diaphragm pump is a volumetric pump whose volume changes due to the reciprocating deformation of the diaphragm. Its working principle is similar to that of the plunger pump. Due to the working principle of the diaphragm pump, the diaphragm pump has the following characteristics.
Features of pneumatic diaphragm pump:
1. The pneumatic diaphragm pump is powered by compressed air;
2. The pneumatic diaphragm pump is a volumetric pump which is caused by the reciprocating deformation of the diaphragm. The working principle is similar to that of the plunger pump. Due to the working principle of the diaphragm pump, the diaphragm pump has the following characteristics:
(1) The pneumatic diaphragm pump will not overheat: the diaphragm pump is powered by compressed air, which is an expansion and heat absorption process when exhausting and the temperature is reduced during operation without harmful gas discharge;
(2) No spark is generated: the pneumatic diaphragm pump prevents static sparks after the power is grounded without power;
(3) can pass the liquid containing particles: because the volumetric work and the inlet is a ball valve is not easy to be blocked;
(4) The shearing force on the material is extremely low: how to suck in when working, so the agitation of the material is minimum for the transportation of unstable substances;
(5) Flow rate can be adjusted by adding a throttle valve at the material outlet;
(6) The pneumatic diaphragm pump has a self-priming function;
(7) The pneumatic diaphragm pump can run empty without danger;
(8) The pneumatic diaphragm pump can work in diving;
(9) Pneumatic diaphragm pumps can transport a wide range of fluids, from low viscosity to high viscosity, from corrosive to viscous;
(10) The pneumatic diaphragm pump has no complicated control system, no cables, fuses, etc.;
(11) The pneumatic diaphragm pump is small in size, light in weight and easy to move;
(12) It is easy to maintain without lubrication, and it will not pollute the working environment due to dripping;
(13) The pump can always be kept efficient without being reduced by wear;
(14) No dynamic seal maintenance is easy to avoid leakage and no dead point when working.
Features of the electric diaphragm pump:
1. The electric diaphragm pump does not need to immerse water for self-priming capacity of more than 7 meters;
2. The electric diaphragm pump has good performance, and the particles and mud with a diameter of less than 10 mm can pass without difficulty;
3. Since the diaphragm will be separated by the conveying medium and the transmission mechanical parts, the medium will never leak outwards, and the service life of the pump itself is greatly extended. According to different dielectric diaphragms, it is divided into neoprene rubber, fluorine rubber and nitrile rubber. Can fully meet the requirements of different users;
4. The electric diaphragm pump is small in size and light in weight. Due to the adoption of the planetary cycloidal transmission structure, the pump type can be obtained in a small size. For example, compared with the same type of pump, its volume and weight are reduced by about half;
5, electric diaphragm pump body flow part can be divided into cast iron, stainless steel according to user requirements "target = _blank> stainless steel, rubber, motor is divided into ordinary, explosion-proof, speed control, etc.
