<\/p>\nWall-hung boiler pressure switch is an important part of the wall-hung boiler, its role is to detect and control the water pressure and gas pressure of the wall-hung boiler, to ensure the safe and stable operation of the wall-hung boiler. Wall-hung boiler pressure switch generally has two kinds, one is the water pressure switch, the other is the gas pressure switch.<\/p>\n
<\/p>\n
Water pressure switch is used to detect and control the water pressure of the wall-hung boiler, it is composed of a spring and a microswitch, when the water pressure reaches a certain value, the spring will be compressed, the microswitch will be closed, sending signals to the controller of the wall-hung boiler, indicating that the water pressure is normal, the wall-hung boiler can be started and run normally. When the water pressure is lower than a certain value, the spring will return to its original state, the microswitch will be disconnected, sending a signal to the controller of the wall-hung boiler, indicating that the water pressure is abnormal, the wall-hung boiler will stop running, in order to prevent dry burns or other malfunctions. The water pressure switch is usually installed on the inlet pipe of the wall-hung boiler, and you can observe the change of water pressure through the display of the wall-hung boiler or the water pressure gauge.<\/p>\n
Gas pressure switch is used to detect and control the gas pressure of the wall-hung boiler, which consists of a diaphragm and a micro switch, when the gas pressure reaches a certain value, the diaphragm will be held up, the micro switch will close, sending signals to the controller of the wall-hung boiler, indicating that the gas pressure is normal, the wall-hung boiler can be ignited normally and combustion. When the gas pressure is lower than a certain value, the diaphragm will be restored to its original state, the microswitch will be disconnected, sending a signal to the controller of the wall-hung boiler, indicating that the gas pressure is abnormal, and the wall-hung boiler will stop combustion, in order to prevent the gas leakage or other malfunctions. Gas pressure switch is usually installed in the wall-hung boiler gas line, you can through the wall-hung boiler display or gas meter to observe the gas pressure changes.<\/p>\n
Wall-hung boiler pressure switch is the safety of the wall-hung boiler, it can provide timely feedback on the state of the wall-hung boiler’s water and gas pressure, so that the controller of the wall-hung boiler to make appropriate adjustments or protective measures to avoid malfunctions or dangers of the wall-hung boiler. Therefore, the use of wall-hung boilers, pay attention to observe the work of the wall-hung boiler pressure switch, if found abnormal, to contact a professional maintenance personnel in a timely manner, check and repair the wall-hung boiler pressure switch, to ensure the normal operation of the wall-hung boiler.<\/p>\n
