手輪螺桿啟閉機手輪螺桿啟閉機結構非常簡單，而且安裝也比較的簡便。主要用在水庫/灌區的閘門升降的控制上!那么手輪啟閉機在使用過程中需要注意那些問題呢?維護和定期檢查。
The structure of the handwheel screw hoist is very simple, and the installation is also relatively simple. Mainly used for controlling the lifting and lowering of gates in reservoirs/irrigation areas! So what are the issues that need to be noted during the use of the handwheel hoist? Maintenance and regular inspections.
1、啟閉機運行過程中有無異常聲響。
1. Is there any abnormal sound during the operation of the hoist.
2、潤滑系統的注油設施，是否完好，油量是否缺少，有無滲漏現象。
2. Check if the lubrication system's oil injection facilities are in good condition, if there is a shortage of oil, and if there is any leakage.
3、啟閉機的控制系統的動作是否靈敏，有效。
3. Is the control system of the hoist sensitive and effective.
4、螺桿有無振動、彎曲變形。
4. Is there any vibration or bending deformation of the screw.
5、安全聯軸器工作中有無打滑現象。
5. Check for any slipping during the operation of the safety coupling.
6、電動軸頸摩擦阻力有無增大，間隙是否適中，有無燙手發熱現象。
6. Check if the friction resistance of the electric journal has increased, if the gap is moderate, and if there is any hot hand or heating phenomenon.
7、機座固定螺絲，有無松動、缺失，底座有無開裂變位。
7. Check if the fixing screws on the base are loose or missing, and if the base is cracked or displaced.
8、閘門開度指示是否準確一致。
8. Is the gate opening indication accurate and consistent.
