Q:How do you do the yellow water from the suction pump?.
If your pump is iron, it must be impossible to avoid rust, and if you replace it with stainless steel, there will be no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.You can change the flow parts into stainless steel, but the price may not be cheap
Q:Submersible pump and self-priming pump which is easy to use?
Dive into the water and leave alone
Q:Why does the pump decay when connected in parallel?
Pump parallel mainly solves the problem of insufficient flow. After parallel, the flow is two and the sum of the pumps. When the flow rate increases, the pressure loss of the pipeline will increase, so the water pump flow in parallel will not be the sum of the two pump flow, but less than the sum of the flow rate. The solution is to increase the diameter of the water supply pipe, reduce the angle bend and shorten the distance.........
Q:What is the current of the pump when it is started?
When the motor starts, the rotor changes from a prohibited state to a rotating state, requiring a great torque, and the current must increase. When the pump starts, because there is water, it is started with load, and the current will be greater.
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
Q:Relationship between power and flow of sewage pump
If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.
Q:How to identify the motor series of pumps
You can also use the motor speed divided by 50, equal to the motor series.
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
See if the impeller problem is loose or something else. Impeller problems are generally
Q:How to measure the temperature of pump body?
Pump body temperature in general, with the hands feel good, and when the hand arrived, can not accept, the pump will have a problem. Specific by their touch cooked.
Q:The efficiency of water pump frequency conversion is very low, why?
Variable frequency pump running normally, its flow and lift is lower than the power frequency operation, that is for sure. The so-called power frequency operation is full speed operation, of course, the head and flow is the highest.Frequency conversion is mainly to save power and reduce the running loss of equipment. The so-called efficiency, but also by the correct selection, the actual pump head and flow as close as possible, the actual working conditions for the best.
