Use, Maintenance and Common Troubleshooting of Air Pump
Use, Maintenance and Common Troubleshooting of Air Pump
Use of (I) air pump
(1) When the pneumatic pump is used, the gas circuit valve should be adjusted to gradually start the pump to avoid the rapid start of the pump.Pump causes shock.
(2) The frequent startup and shutdown of the pump should be avoided, and the idling of the pump for a long time should be avoided.
(3) Lubricating oil should be regularly filled into the air valve from the air path.
(4) When transporting high viscosity media, the pump should be operated at low frequency to avoid cavitation and suctionInsufficient.
(5) The gas valve should be cleaned regularly to ensure the free operation of the gas valve system.
(II) maintenance and common fault handling
1. Routine maintenance
(1) Add a few drops of mechanical oil to the container below the air regulator (pneumatic triplet) every month. Pump notIt should be over-lubricated, otherwise the oil will be removed from the muffler and contaminate other equipment. Excessive lubrication will also cause the pumpOperation failure.
(2) The calibration period of fastener torque can be changed with the utilization rate of diaphragm pump. As a regular requirement, eachFastening parts shall be calibrated every two months.
(3) The pump should be washed frequently to prevent the pumped fluid from drying in the pump and causing damage to the pump.
(4) If the pump needs to be continuously unused, flush the pump and relieve pressure before storage.
2. Common fault handling
(1) The pump is weak and the pumping speed slows down
This phenomenon generally has the following several situations:
First, the air pressure of the air source decreases. First, look at the air pressure gaugeWhether the pressure is normal, then check the opening position of the air source valve. If the air source is opened and closed by solenoid valve,Check whether the plastic valve plate of the solenoid valve is damaged, resulting in the plastic valve plate can not be fully opened;
Second, the silencer is blocked,Gas cannot be discharged quickly, resulting in slow pumping speed;
Third, the compressed air has more water or impurities, resulting inAfter entering the valve chamber of the diaphragm pump, wear and block the normal reciprocating motion of the piston and the small slider;
Four is the valve chamber air valve coverLong time by the impact of air pressure, resulting in air valve cover gasket leakage;
Five is the pump internal shaft seal ring wear and stringGas.
(2) Reduced traffic.
This phenomenon generally has the following several situations:
One is the inlet and outlet check valve (ball valve seat) wear smaller,Or there are strips and large particles stuck in the ball, resulting in the material liquid at the discharge port being refolded during material suction, and the material being discharged again.
Press back from the feed port;
Second, the diaphragm sheet is stretched and deformed for a long time, resulting in a smaller volume of the material cavity;
Three is membraneThe piece is damaged and the center shaft does not go in place when it is driven.
(3) The pump does not move.
This phenomenon may have several situations:
First, the piston and V-ring in the valve chamber are severely worn and stuck;
Second, the shaft sleeve of the shaft is worn, and the shaft sleeve should be replaced at this time;
Three is the pump shaft at both ends of the pressure plate damage;
Four is two layers
Diaphragms are all broken; five are diaphragm pumps inverted or laid flat.
(4) there are impurities or oil in the material.
This phenomenon is generally caused by diaphragm pump diaphragm rupture, found that the situation immediately shut down the pump into the air source, stopStop working and replace the diaphragm.
