The diaphragm pump can be divided into pneumatic, electric and hydraulic according to the power used by the actuator. It is a pneumatic diaphragm pump with compressed air as the power source and an electric diaphragm pump with electric power as the liquid medium. Pressure-powered electric diaphragm pumps, such as oil, etc., in addition to their functions and characteristics, there are solenoid valves, electronic, intelligent, fieldbus diaphragm pumps. Diaphragm pumps come in many different types and structures, and are constantly being updated and changed. Valves are generally versatile and can be matched to pneumatic actuators or to electric actuators or other actuators.
Pneumatic diaphragm pumps are now more widely used and accepted by the public. There are many diaphragm pumps in many companies such as chemical, spray, and ceramics. Diaphragm pumps can be roughly divided into two categories, one is an electric diaphragm pump and the other is a pneumatic diaphragm pump. And the application of pneumatic diaphragm pump is more than Zui. So here I will talk about a little maintenance experience on the pneumatic diaphragm pump. I hope to help the vast number of equipment maintenance personnel. And hope that this article will play a role in attracting jade. Let everyone come together to discuss and improve together.
common problem:
First, the pump is weak and the pumping speed is slow. This kind of phenomenon generally has the following situations:
1. The air pressure is reduced. First look at the pressure of the intake pressure gauge, the pressure value is normal in 4 to 7 kg. Then check the opening position of the gas source valve. If the gas source is opened or closed with a solenoid valve, check the plastic valve of the solenoid valve for damage, which will cause the plastic valve to not open completely.
2. The muffler is clogged, the gas cannot be discharged quickly, and the pumping speed is slowed down.
3. Excessive water or impurities in compressed air. After entering the diaphragm pump valve, block the air inlet or catch the valve spool. Fourth, the upper and lower end caps of the valve are damaged by the impact of the valve core due to the impact of the valve core. Fifth, the four inner seal rings of the inner shaft of the pump are worn and gas.
Second, the flow is reduced. This kind of phenomenon generally has the following situations:
1. The inlet and outlet check valves (plastic balls) wear less. Or there are strips, large particles stuck in the plastic ball. When the material is discharged from the discharge port during the suction, the material is pressed back from the inlet.
2. The diaphragm is stretched and deformed at a constant time, resulting in a smaller volume of the material chamber. The third is black, and the thick layer of the diaphragm is broken. When the center shaft is driven, it is not in place.
3. The pump does not move. There may be several situations in this phenomenon. First, the spool is severely worn and stuck. The second is the wear of the shaft sleeve of the center shaft. The copper sleeve should be replaced at this time. The third is that the screw at both ends of the center shaft falls. Fourth, both diaphragms are broken. Fifth, the diaphragm pump is inverted or laid flat. The spool cannot be returned (* generation and second generation)
4. There are impurities or oil stains in the material. This is generally caused by the rupture of the diaphragm.
5. Import and export leakage. First, the screw is not fastened, the second is the deformation of the ball seat or the O-ring is damaged, and the third is that the pump casings at both ends are not inclined to the upper hole position, so that the two discharge ports or the feed ports are not on the same plane.
Diaphragm pump use should pay attention to some problems and maintenance
Diaphragm pumps, also known as control pumps, are the main type of actuators that change the flow of fluids by means of power operations by receiving control signals from the output of the modulation unit. Diaphragm pumps typically consist of actuators and valves. Using compressed air as the power source, for various corrosive liquids, liquid with particles, high viscosity, volatile, flammable, highly toxic liquid, can be exhausted.
