The specific operation method of screw refrigeration compressor maintenance
Before the screw compressor must be overhauled, if possible, unload the slide valve to the "0" position, shut down normally, and cut off the power supply. The pipeline connected to the compressor should be cut off and the refrigerant and lubricating oil i 器2 䀀 ᅵ皥 䖒皦즠Ʋ煔क़ 㲈Ʋ 䌁皦 ᮔDž༬皧煞क़Ѐ 呄ᠾ鹨់༹皧 ࠄ 00령ꐱ댁珵뛐珵Љ 䕄ྦ 뤂ᐱ뚜珵 ᴴᏩ呄ᠾ퍘ᒥ 鹨់ᩄ ꋔྦ 瑉浥 巠皱㙲皦抐皱 巠皱 ੨皦柘皱 ᅵ皥 ب 巠皱㙲皦忈皱 ੨皦柘皱 즠Ʋǜ 勁皦즠Ʋب ǜ

About the role of screw air compressor inverse proportional valve
The inverse ratio valve is used in conjunction with the disc air intake control. When the system pressure increases due to the decrease in air consumption and reaches the set pressure of the inverse ratio valve, the inverse ratio valve acts and reduces the control air output.

Structure diagram of single vane compressor_Main features of single vane compressor
The basic structure and working principle of single slide compressor.<img src="{{media url="Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor.jpg"}}" alt="" /> Single sliding vane compressor is also called scraper compressor or rolling rotor compressor. Its structure is shown in Figure 3-7. A cylindrical eccentric rotor (also called a piston) is installed in the cylinder, and the center of rotation of the rotor coincides with the center of the cylinder. In the middle of the upper part of the cylinder, a scraper that can slide up and down is installed. Due to the force of the spring,<img src="{{media url="Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor2.jpg"}}" alt="" />

Debugging method of servo motor
Before wiring, initialize the parameters. On the control card: select the control method; clear the PID parameters; let the default enable signal turn off when the control card is powered on; save this state to ensure that the control card is in this state when it is powered on again.

What are the tips for using screw air compressors
The set unloading pressure of the air compressor pressure regulator is adjusted with the upper adjusting bolt. Turn the bolt clockwise to increase the unloading pressure, and rotate it counterclockwise to reduce the unloading pressure. The differential pressure value is adjusted by the differential knob at the bottom. Turn it counterclockwise, the pressure differential value of the air compressor decreases, and clockwise
