The temperature control valve of the screw air compressor is a key component of temperature control. Its function is to control the injection temperature, thereby ensuring that the exhaust temperature is maintained within a suitable range. The following is an introduction to the temperature control valve of the screw air compressor:

1.Exhaust temperature limit: The exhaust temperature of the screw air compressor cannot be too high or too low. Usually, the upper limit of the exhaust temperature is 110°C, and the lower limit is affected by the ambient temperature, humidity, and pressure. Avoid condensation during operation. Condensation will cause the lubricating oil to emulsify and destroy the cooling and lubrication effect.

2.Lubrication and cooling system: The screw air compressor achieves internal cooling by injecting a large amount of lubricating oil into the cylinder body. This cooling method has a significant cooling effect, reduces power consumption, and improves efficiency.

3.Thermostatic valve principle and structure: Thermostatic valve uses special temperature-sensitive paraffin as the valve core to control the fluid temperature. It uses the linear volume expansion characteristics of paraffin during the solid-liquid phase change process to convert the temperature change signal into valve core displacement to control the lubricating oil flowing through the oil cooler.

4."Dividing flow" and "mixing flow": The temperature control valve adopts the "dividing flow" control method, which is usually used in medium and small screw machines, while the "mixing flow" control method is more used in larger screw machines.

5."Dividing flow" and "mixing flow": The temperature control valve adopts the "dividing flow" control method, which is usually used in medium and small screw machines, while the "mixing flow" control method is more used in larger screw machines.

6.Cleaning and maintenance: The temperature control valve needs to be cleaned of dirt and the spring valve core needs to be replaced regularly. When cleaning, pay attention to the disassembly and installation steps. If there is any damage or deformation, replace it with a new part.

7.Precautions for use: During the installation and use of the temperature control valve, the steps should be strictly and maintenance should be performed regularly to ensure that it does not affect its normal function.

Through the above introduction, we understand the working principle, importance and maintenance methods of the screw air compressor temperature control valve. Correct maintenance and use can extend the service life of the temperature control valve and ensure the stable operation of the air compressor.
