Solenoid Valves And Vacuum Gauges New Refrigerant Vacuum Pump

1. Solenoid valve

Solenoid valve is the key control element in vacuum pump, and its working principle is to control the flow of gas or refrigerant through the magnetic field generated by electromagnet.

Structural characteristics

• Solenoid valve is usually composed of valve, valve seat, spool and solenoid.

• The valve and seat are usually made of corrosion-resistant materials such as stainless steel to ensure stability and reliability for long-term use.

• The spool is a cylindrical part that fits with the valve and is usually made of copper, stainless steel, etc. It is used to control the passage of fluid.

• The solenoid consists of a coil and a core. When the coil is energized, it generates a magnetic field to attract the core, thus realizing the control of the spool.

Working Principle

• When the solenoid is energized, the magnetic field generated causes the spool to be attracted, thus opening the pathway for gas or refrigerant.

• When the solenoid is de-energized, the valve spool returns to its original position under the action of the spring and other reset devices, closing the pathway.

Function

• The solenoid valve precisely controls the flow of refrigerant through the vacuum pump, ensuring that the system responds quickly and accurately when needed.

• By controlling the on-off of the solenoid valve, the circulation and discharge of refrigerant can be realized, thus maintaining the normal operation of the system.

2.Vacuum Gauge

Vacuum gauge is an instrument used to measure the vacuum degree of the internal or external system of the vacuum pump.

Working Principle

• The working principle of vacuum gauge is based on the movement and collision of gas molecules. When the vacuum pump works, the internal gas molecules are pumped out and discharged to the external environment, thus reducing the gas pressure inside the pump chamber.

• Vacuum gauges assess the vacuum level by measuring the number of gas molecules or the pressure inside the pump chamber.

Functionality

• The vacuum gauge monitors the vacuum level inside the vacuum pump in real time, ensuring that the system operates within the required vacuum range.

• By taking readings from the vacuum gauge, you can understand the operating status and performance of the system, so that timely adjustment and maintenance can be carried out.
