重慶升降機(jī)的下降閥失靈的解決辦法如下。The solution to the failure of the Chongqing elevator down valve is as follows.
 
1.如果重慶升降機(jī)下降閥失靈，在按下下降按鈕的情況下，檢查下降閥是否有電。若無電，設(shè)法排除；若有電，則排除下降閥本身故障，或更下降閥。下降閥應(yīng)保持清潔、潤滑。If the Chongqing elevator down valve failure, in the case of the press down button, check whether there is electricity down valve. If no electricity, try to rule out; if there is electricity, the valve itself is excluded from the failure, or more down valve. Down valve should be kept clean and lubricated.

2.重慶升降機(jī)下降閥封閉不嚴(yán)，檢查下降閥是否有電，如有電則排除下降閥本身故障或更換下降閥。下降閥的滑閥必須保持清潔，且移動(dòng)靈活。Chongqing lift down valve closed lax, check whether there is electricity, such as electricity is excluded from the fall in the valve itself or the replacement valve failure. Drop valve spool valve must be kept clean, flexible and mobile.

3.重慶升降機(jī)油缸內(nèi)漏，更換油缸密封件。Chongqing lift cylinder leakage, replace the cylinder seal.

4.重慶升降機(jī)下降速度控制閥失調(diào)，調(diào)整下降速度控制閥，如調(diào)節(jié)無效更換新閥。Chongqing elevator down speed control valve imbalance, adjust the decline rate control valve, such as the adjustment of the new valve replacement.
