10 Questions You Should to Know about Double-stage compression permanent magnet variable frequency screw compressor Factory China

Common problems of permanent magnet variable frequency air compressor intake valve

For more information, please visit our website.

The intake valve of the permanent magnet variable frequency air compressor can be said to be an intake control combination valve, which has the functions of intake control, loading and unloading control, capacity adjustment control, discharge, prevention of unloading or fuel injection during shutdown, and its operation rules can be summarized as : Power on to load, jump to stop to unload. The air compressor intake valve generally has two structures: a rotating disc and a reciprocating valve plate.

 

There are two control methods for the intake valve: one is the switch method, when the pressure of the gas storage tank reaches the upper limit preset value, the intake port is closed; when the pressure drops to the lower limit preset value, the intake port is opened again.

 

The other is the capacity adjustment method. When the air storage tank reaches a certain pressure, the air inlet is slightly closed under the control of the proportional valve. When the pressure of the air storage tank is further expanded, the air inlet is further reduced; when the air storage tank When the pressure drops slightly, the air inlet will increase to keep the pressure stable within a certain range; when the pressure does not reach the capacity adjustment pressure, the air inlet valve disc will be fully opened and the air inlet will be opened. The intake valve of the permanent magnet variable frequency air compressor is generally a normally closed valve, which prevents a lot of gas from entering the machine head when the air compressor is started, and increases the starting current of the motor. There is an intake valve on the intake valve, which is used to avoid high vacuum in the machine head when the equipment is running and fully loaded, which will affect the atomization of grease. Frequently asked questions about permanent magnet variable frequency air compressors:

(1) The main reasons why the intake valve of the permanent magnet variable frequency air compressor is not loaded are: the solenoid valve is not energized; the solenoid valve is damaged; The fat change causes the friction between the piston seal ring of the intake valve and the cylinder to increase and cannot be calibrated; the volume control valve controls the intake valve to close.

 

Cleaning method: Check the equipment circuit to ensure that the solenoid valve is normal; replace the solenoid valve coil or the entire solenoid valve body; Change the high-quality grease; adjust the volume control valve (module) of the intake valve, it is not recommended for laymen to do it by themselves.

 

(2) Non-unloading The main reasons for the non-unloading of the intake valve are: the solenoid valve is not powered off; the solenoid valve is damaged; the small hole in the solenoid valve is blocked; the retention hole in the intake valve is blocked; the discharge rate is too fast.

 

Cleaning method: check the circuit, repair the solenoid valve to be normal; replace the solenoid valve coil or the entire solenoid valve body; disassemble the solenoid valve to eliminate internal impurities; disassemble the intake valve to eliminate impurities in the trapped hole; adjust the discharge rate, increase the size of the air pipe or Add a bend.

 

(3) Intake valve oil pump The main reasons for the intake valve oil pump are: poor oil and gas separator; blockage of pump oil throttle valve; poor air filtration effect, and poor sealing caused by adhesion of impurities on the protruding surface of the intake valve core; The air compressor works in a harsh environment, and the matching pair of the intake valve piston and the torsion spring seat is damaged.

 

Cleaning method: check the oil and gas separator, and replace the new oil separation core; remove the pump oil throttle valve, the internal impurities of the throttle valve; check the air filter, and replace the new air filter, the intake valve pipeline is clean and tidy; reduce the maintenance cycle And suggest customers to improve the air compressor office environment.

Product Description

Features of Baldor Permanent Magnet Inverter AC Screw Air Compressors
1. The airend and motor is integrated connected with each other. More compact system structure makes smaller size and smaller space to be occupied on site.
2. The system efficiency is 12%~18% higher than normal fixed speed compressor. The energy saving level is above the first class standard according to GB19153-2009.
3.  More intelligent controlling system. The air capacity and system temperature could be adjusted automatically. The compressor is running in a stable temperature. The operation would be very easy.
4.  Rational design to optimize the system reliability and ensure an easy maintenance.
5.  A computer network remote monitoring system is used in the controller. Users can send orders to the controller according to the displayed data to realize a remote control to the compressor.


How does Baldor Permanent Magnet Inverter Screw Air Compressor save energy more than normal variable frequency screw air compressor and fixed speed screw air compressor?
1. High transmission efficiency due to integrated structure of the airend and motor. There is no coupling shaft between the airend and motor. The motor rotator directly connected with the airend bearing, there is no motor bearing, no oil seal, no belt between the airend and motor, no coupling shaft, no gears, so not any mechanical friction and transmission loss. The transmission efficiency is 100%, and no such periodical maintenances for the bearing, oil seal or coupling shaft.

2. High motor efficiency which is kept to be about 95%, and the power factor is nearly 100% which is 5%~10% higher compared with the same specification of the Asyn. motor. The motor efficiency is always high either heavy load or light load.
3. No unloading process during the operation. The Permanent Magnet Inverter screw air compressors can save the energy of unloading because the motor rotating speed is controlled by the supplied air pressure. The stable supllied air pressure makes a stable and continous loading process of the air compressor and ensure a best working status of the motor.

What other advantages does the Baldor Permanent Magnet screw air compressor has?
1. Stable air supply. The stepless speed regulation of the inverter ensures a stable air suply with the PID controller or the inverter itself. It can response quickly to large fluctuation of air consumption.
2.Reasonable the magnetic field design and density distribution. Wider motor workng frequency range and lower noise.
3. Smaller size because the motor size is only 1/3 of the normal syn. motor. So the maintenance is very easy.
4. Remote monitoring system. Customers can real-time dynamically monitor the operation of their compressors for the current, voltage, power, temperature, pressure and etc. information. And they can also receive alarm warnings SMS from the compressors to do maintenance. The parameters could also be modified by remote monitoring system.
