Q:Variable flow variable frequency water pump how to adjust the flow?
Variable frequency pump is mainly depending on the frequency converter to adjust the speed of the pump motor, thereby regulating the flow and lift pump, the following Q1/Q2=n1/n2; H1/H2= (n1/n2) -, the frequency range of the frequency converter in 30HZ~50HZ
Q:What is the water pump population pre rotation, what harm?
Is the entrance of water flow in the formation of complex turbulent flow, flow direction, shock, vibration, easy to damage the front entrance device, such as vane impeller, shaft sleeve, sealing element. In order to prevent the emergence of the pre swirl phenomenon, usually the design will inlet than outlet diameter, try to make the entrance flow in laminar flow, according to streamline our design, in order to protect the safety and prolong the service life of equipment.
Q:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:25KW what is the lift of the pump?
2 floor, the following formula is not accurate, the margin of safety is too large.N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85As follows: for reference only: (pump flow * pump lift) / (367* pump efficiency) * pump motor power safety margin (constant general take 1.1-1.2) = pump power.Unit: flow M3/H, head MNow you know the power of the pump, but you do not know the efficiency of the pump and flow, so the pump head can not be calculated.Can the normal operation of pump flow velocity detection using ultrasonic detection equipment, combined with the calculation of pump diameter of the flow and shaft power testing equipment can use foreign advanced measure pump, electric motor with related input parameters to calculate the pump efficiency. Then use the formula above to calculate the pump head.The simple way is to ask the designer directly about the design parameters.
Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?
The intelligent controller of water pump is full of water and automatically shows the shortage of water in the lower pool. The reason is that the sensor is out of order or the line is out of contact. First of all, make sure that the upper limit of your controller is normally open or normally closed. When the upper limit is reached, does this point change? If the original upper limit position is normally open, check the switch and pump insulation.A pump is used to increase the pressure of a liquid or gas, the flow conveying machinery, and "jump" or "flow" is a homonym, is a transliteration of the English pump, is a device used to move liquids, gases or special fluid medium, which is reactive to the fluid machinery. The heart of man and animal can be said to be a natural pump, which carries blood to all parts of the body.
Q:Difference between primary hot water pump and two hot water pump
A hot water pump is a water pump circulating between the boiler and the heat exchanger, and the two hot water pump is a circulating water pump between the heat exchanger and the user. That is, there is no relationship between a water pump and heating users.
Q:What motor does the pump use?
Single-phase general use YL series, three-phase general use Y, Y2 series.
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
It freezes at 0 degrees, and the pump runs and gets stuck.
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.
Q:What is the difference between a fire pump and a living water pump?
Fire pump and life pump essential difference, simply said: in the materialBecause we are used every day in the life of the pump, so there is no rust phenomenon, and the fire pump can not occur even in a hundred years to spend time, even some of the fire pump until life exceed the standard is not used, only periodically, so in order to prevent emergencies caused economic losses and personnel to design special pump different from the life of pump material as fire pump. Single stage centrifugal pump. The multistage centrifugal pump and pump life principle without any distinction, but the material will cast steel replacing 304, 309 stainless steel or copper materials, different specifications of other fire pump structure, materials should use copper and stainless steel.
