螺桿式空壓機(jī)檢修前后注意哪些事情？
What should we pay attention to before and after the maintenance of screw air compressor?
答：（1）維修保養(yǎng)前應(yīng)停止機(jī)組運(yùn)行，關(guān)閉排氣閥門(mén)，斷開(kāi)機(jī)組電源并掛上警告牌，放空機(jī)組內(nèi)壓力（各壓力表顯示為“0”）后才能開(kāi)始維修工作。拆卸高溫組件時(shí)，必須待溫度冷卻到環(huán)境溫度后方可進(jìn)行。
Answer: (1) before maintenance, stop the operation of the unit, close
the exhaust valve, disconnect the power supply of the unit, hang a
warning board, and vent the pressure in the unit (each pressure gauge
shows "0"). When disassembling high-temperature components, it must be
carried out after the temperature is cooled to the ambient temperature.
（2）用正確的工具維修空壓機(jī)。
(2) Repair the air compressor with the correct tools.
（3）推薦使用螺桿空壓機(jī)專(zhuān)用油，檢修后不同牌號(hào)的潤(rùn)泥桿 保定古箏 塑料增韌劑 拱形護(hù)坡模具 保定空調(diào)維修 托輥生產(chǎn)線滑油不允許混用。
(3) It is recommended to use special oil for screw air compressor. After
maintenance, lubricating oil of different brands is not allowed to be
mixed.
（4）空壓機(jī)原裝備件是專(zhuān)門(mén)設(shè)計(jì)、制造的，推薦使用正宗備件，以保證空壓機(jī)工作的可靠性、安全性。
(4) The original spare parts of the air compressor are specially
designed and manufactured. It is recommended to use authentic spare
parts to ensure the reliability and safety of the air compressor.
（5）沒(méi)有得到制造廠的許可，不要對(duì)壓縮機(jī)作任何影響安全性、可靠性的改動(dòng)或增加任何裝置。
(5) Do not make any changes affecting the safety and reliability of the
compressor or add any devices without the permission of the
manufacturer.
