  • Pressure Switch For Air Conditioning Refrigeration System

    Pressure Switch For Air Conditioning Refrigeration System

    When the pressure in the system is higher or lower than the safe pressure, the pressure sensor in the controller will act immediately to make the contacts in the controller turn on or off, and the equipment will stop working at this time;When the pressure in the system returns to the safe pressure range of the equipment, the pressure sensor in the controller is reset immediately, so that the contacts in the controller are turned on or off, and the equipment is working normally at this time.Mainly used in air conditioning and refrigeration systems, vacuum pressure control systems, water pressure control systems, steam pressure control systems, oil and gas pressure control systems, etc., to prevent the pressure in the system from being too high or too low to ensure that the system is always within a safe working pressure range.

  • Pressure Switch For Refrigeration System

    Pressure Switch For Refrigeration System

    The pressure switch is mainly used in the refrigeration system, in the pipeline circulation system of high pressure and low pressure, to protect the abnormal high pressure of the system to prevent damage to the compressor.

    After being filled, the refrigerant flows into the aluminum shell (that is, inside the switch) through the small hole under the aluminum shell. The inner cavity uses a rectangular ring and a diaphragm to separate the refrigerant from the electrical part and seal it at the same time.

  • AC compressor trinary low high pressure switch with wire

    AC compressor trinary low high pressure switch with wire

    This is an air conditioner three-state pressure switch, which includes a high and low pressure switch and a medium voltage switch. The three-state pressure switch is installed on the high-pressure pipeline of the air-conditioning system.

    Low-pressure switch: When the air-conditioning system leaks or the refrigerant is low, in order to protect the compressor from damage, the control circuit of the compressor is forcibly cut off to stop the compressor.

    Mid-state switch: When the condensing pressure is high, force the condensing fan to rotate at a high speed to reduce the high pressure pressure and increase the cooling effect.

    High pressure switch: In order to prevent the system pressure from being too high, causing the system to explode, the compressor is forced to stop working. When the high-pressure pressure of the air conditioner is abnormally high, the high-pressure switch is opened to cut off the control circuit of the compressor, and the air-conditioning system stops working.

  • Auto Air Conditioning Refrigeration Pressure Switch

    Auto Air Conditioning Refrigeration Pressure Switch

    The pressure switch is installed on the high-pressure side of the air-conditioning system.When the refrigerant pressure is ≤0.196MPa, since the elastic force of the diaphragm, the butterfly spring and the upper spring is greater than the pressure of the refrigerant, the high and low pressure contacts are disconnected (OFF), the compressor stops, and low pressure protection is realized.

    When the refrigerant pressure reaches 0.2MPa or more, this pressure is higher than the spring pressure of the switch, the spring will bend, the high and low pressure contacts are turned on (ON), and the compressor operates normally.

  • Sealed airbrush compressor pressure switch

    Sealed airbrush compressor pressure switch

    The working principle of the pressure switch is that if the pressure in the pressure switch system is higher or lower than the initial set safety pressure value, the internal disc of the pressure switch can detect and issue an alarm in time, and movement occurs, and the connection of the pressure switch is connected to the power supply , So that the connection of the pressure switch turns on or off the power.The water pressure switch is usually set to a fixed value when in use. That is, when the actual value is less than the fixed value or greater than the fixed value, an alarm will occur and movement will occur to cause a connection with another link. Turn the power on or off. When the water pressure in the system reaches a fixed value, it returns to its original state.

  • Single-Pole Single-Throw Automatic Reset Pressure Controller

    Single-Pole Single-Throw Automatic Reset Pressure Controller

    This series of pressure controllers mainly use the built-in stainless steel reversible action diaphragm to work in the opposite direction after sensing a certain pressure.When the diaphragm moves, a guide rod will drive the electrical contacts to close or open. When the induced pressure drops below the recovery value, the switch can automatically reset.
