product description

PA-SDN/SSNS series Pressure controller

Pressure controller vendor_Pressure controller

Application:

Pressure controller is subjected to stress signals and action of a kind of automatic control device,In the refrigeration unit, when the compressor discharge pressure more than set point of suction pressure below the set value, the pressure controller will automatically cut off the circuit, make the compressor parking and security protection effect

Working principle:

Pressure controller is subjected to stress signals and action of a kind of automatic control device,In the refrigeration unit, when the compressor discharge pressure more than set point of suction pressure below the set value, the pressure controller will automatically cut off the circuit, make the compressor parking and security protection effect

In the refrigeration system, the high voltage end (or single high pressure) of the controller is connected with the compressor's exhaust port, and the low pressure end (or single low pressure) is connected with the suction port of the compressor. When the exhaust pressure of the compressor exceeds the set point of the controller, the contact of the high voltage end of the controller is disconnected. and the circuit is cut off and the compressor stops. When the suction pressure of the compressor drops to a point lower than the controllar's low pressure.setting,the contact of the low-voltage end of the controller is disconnected,the electrical appliance is cut off,and the compressor stops. The above situation is the opposite, the high pressure compressor exhaust pressure drops gradually to the controller set point of the lower limit,or low pressure compressor suction pressure gradually recovered to controller set point highs,controller of micro switch contact closure, Connect the circuit, the compressor is restarted. Therefore,the pressure controller plays an important role in the compressor's high and low pressure protection, which is of great significance to the cooling of the cold storage and the reasonable operation of refrigerating machine.

The ZSFG deluge alarm valve is a lever structure, with anti-reset function, in line with GB5135.5-2003 standard products. It is  widely used in all kinds of open system (open sprinklers on the side line of the system). Such as deluge system, water curtain system  and water spray system. The ZSFM deluge alarm valve is opened to release the pressure from the diaphragm chamber and open the  disc, using the side pressure of the water supply. Pressure release in diaphragm chamber can be carried out in many ways, that is,  electrical guide, wet guide and dry guide.
