What are the reasons for the lack of water in the impeller of the double suction pump after the change of the impeller?
How can I do without water pump? Since the suction pump is not Sheung Shui reasons? The most frequently encountered problem is that the suction pump does not supply water So, what exactly is the reason? Today, Le pump technical personnel will give you the analysis, and find a solution. 1. the voltage is too low: adjust the voltage 2., the suction line is too high or the suction line is too long: reduce the suction stroke or shorten the pipeline 3. mechanical density...
Hand into the water inlet, plus water diversion power, small suction may water seal broken, suction large water inlet leak. The general suction pump with 30 seconds hand up, (try not leakage) safety firstWater enters from both sides of the impeller, and the casing is divided into two halves from the middle of the shaft.
No water, there is no liquid, the opening of the inlet valve, pump steering is correct.If it is really the self-priming pump and there is no problem, do not need to check, the proposed demolition to try again after 3~5 minutes, can see the water, but the pump should be added to water, do not need to fill, probably about half of it! If it still fails, look at whether the metal inlet is leaking (from which you should not), or whether the pipe is flat (if it needs to be deflated)...
