Dry screw vacuum pump is a high-tech product, which is mainly used in high-purity vacuum process. It has high vacuum degree, can adapt to harsh working conditions, has the ability to extract condensable and particulate gas, especially suitable for clean environment, and is easy to do anti-corrosion treatment. What should be paid attention to in routine inspection of screw vacuum pump?

每日檢查的內容主要包括：1、油位線是否過高或過低；2、是否有足夠的冷卻水流量；3、檢查真空泵兩端端蓋的表面溫度是否正常；4、檢查進氣口與排氣口的壓力；5、用電流表檢查電動機負載，如果功率增加過多就表示有異?，F象。

The contents of daily inspection mainly include: 1. Whether the oil level line is too high or too low; 2. Whether there is enough cooling water flow; 3. Check whether the surface temperature of the end covers at both ends of the vacuum pump is normal; 4. Check the pressure of air inlet and exhaust port; 5. Check the motor load with an ammeter. If the power increases too much, it means that there is an abnormal phenomenon.

每日檢查的基礎上，每月檢查包括：1、檢查潤滑油顏色，確定是否需要更換；2、檢查油位，如果油位下降太快，則需要檢查密封。

On the basis of daily inspection, monthly inspection includes: 1. Check the color of lubricating oil to determine whether it needs to be replaced; 2. Check the oil level. If the oil level drops too fast, check the seal.

每季度檢查內容：1、檢查冷卻水流量以及顏色，定期清理水套和水管；2、檢查并更換非驅動端端蓋的潤滑脂；3、檢查并更換驅動端端蓋內的潤滑油。

Quarterly inspection contents: 1. Check the cooling water flow and color, and regularly clean the water jacket and water pipe; 2. Check and replace the grease of non drive end cover; 3. Check and replace the lubricating oil in the drive end cover.

每半年檢查螺桿真空泵的進排氣管道。

Check the intake and exhaust pipes of screw vacuum pump every six months.

每年例行檢查內容：1、檢查真空泵的密封；2、檢查螺桿真空泵的接觸面：螺桿與泵體。卸下真空泵的進氣管道，檢查螺桿與泵體的接觸面。

Annual routine inspection contents: 1. Check the sealing of vacuum pump; 2. Check the contact surface of screw vacuum pump: screw and pump body. Remove the intake pipe of the vacuum pump and check the contact surface between the screw and the pump body.

看到這里相信你對螺桿式真空泵的例行檢查有了一定的了解，另外與螺桿式壓縮機類似，螺桿式干式真空泵的工作過程可分為吸氣、壓縮和排氣三個過程。隨著轉子的旋轉，每對相互嚙合的齒相繼完成相同的工作循環(huán)，現在以其中一對齒來說明。如果您還有其他關于螺桿式真空泵的問題不妨來電咨詢，小編竭誠為您服務。

I believe you have a certain understanding of the routine inspection of screw vacuum pump. In addition, similar to screw compressor, the working process of screw dry vacuum pump can be divided into three processes: suction, compression and exhaust. With the rotation of the rotor, each pair of meshing teeth completes the same work cycle one after another. Now, one pair of teeth is used to illustrate.
