Working principle： Expansion and contraction driven: The constant temperature valve mainly operates based on the principle of thermal expansion and contraction. Special expansion temperature-sensitive paraffin wax and other components are usually used as the temperature sensing elements. When the oil temperature rises to the melting point of the paraffin wax, the wax expands significantly, generating a large force that pushes the push rod, causing the valve core to move and opening the valve; when the oil temperature drops, the paraffin wax contracts due to the cold, and under the spring rebound effect, the valve core resets, closing or reducing the valve opening. Oil passage control: The expansion and contraction of the valve core is used to adjust the changes in the oil passage between the valve body and the housing, thereby controlling the proportion of lubricating oil entering the oil cooler. When the oil temperature is lower than the set value, the valve closes or the opening degree decreases, and the lubricating oil directly returns from the oil-gas tank to the main unit, achieving rapid heating; when the oil temperature is higher than the set value, the valve opens, allowing the lubricating oil to enter the cooler for cooling, and the cooled lubricating oil returns to the main unit, thereby ensuring that the rotor temperature remains within the set range.

Why is lubricating oil used for the screw rod? 1.Reduce friction: The grease can form a lubricating film on the surface of the screw rod, reducing the friction coefficient and thereby minimizing wear and heat generation. 2.Preventing rust: The grease has certain anti-corrosion properties, which can prevent the screw rod from rusting due to oxidation or moisture. 3.Transmitting power: A certain oil film is formed between the screw rods, which helps to smoothly transmit power, reducing mechanical vibration and noise. 4.Sealing function: The grease performs the sealing function, preventing dust and moisture from entering the screw rod. 5.Anti-rust and anti-corrosion: Lubricating grease is an excellent anti-rust and anti-corrosion agent.

The solenoid valve of the air compressor is a key component for controlling the flow direction, on-off and system protection of compressed air. It is mainly divided into two types: loading solenoid valves and venting solenoid valves.
