Southern self-absorption sewage pump maintenance tips Daquan

Self-priming sewage pump is commonly used in the South a pump. The principle is the use of water flow momentum, impeller driven pump impeller to the river above the water. The pump can be pumped into the river to pump water, but it must be in immediate rush or fall. We understand the characteristics of self-priming sewage pump, and then look together now, how do we maintain a self-priming sewage pump. South self-absorption sewage pump maintenance tips Daquan First is the direction, to regularly check the parts are abnormal, if there is abnormal, should refer to the manual or other information check, if necessary, replacement parts. Check the self-priming pump pipe and the combination of loose phenomenon. Turn the self-priming pump with your hand or a tool to see if the drain pump is flexible. Second, try to control the flow and lift of the self-priming pump within the range indicated on the plate, in order to ensure that the self-priming pump operates at the highest efficiency, in order to obtain the maximum energy-saving effect. Third, the self-priming pump during operation, the bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C. Fourth, if it is found that abnormal self-priming pump sound should stop immediately check the reasons. Fifth, to stop using the sewage pump, first close the gate valve, pressure gauge, and then stop the motor. Sixth, self-priming sewage pump for a long time do not need to use and in the winter season, after parking, you need to unscrew the lower part of the drain plug to drain the media to the net. Prevent cracking (if the sewage please clean the pump chamber with clean water).
