Q:What are the categories of pumps?
First, select the pump to meet the requirements of the headThe so-called head refers to the required lift, and not lift the water height, clear this point, the choice of water pumps is particularly important. Pump lift is about 1.15 to 1.20 times the height of lifting water. If the vertical height of a water source to the water is 20 meters, the required lift is about 23~24 meters. When selecting a pump, the pump head should be close to the required head, and the general deviation is not more than 20%. In this case, the efficiency of the pump is the highest, and it is more energy efficient, and the use will be more economical. If the lift on the nameplate is much smaller than the required lift, the pump can not meet the needs of users, even if the water can be pumped, the water is also very poor. But in turn, the high lift pump for low head, there will be heavy traffic, resulting in motor overload, if long time operation, the motor temperature, the winding insulation layer will gradually aging, and even burning motor.Two, select the appropriate flow pumpWater pump flow, that is, the amount of water is generally not too large election, otherwise it will increase the cost of water pumps. Should be selected as needed, such as the use of the user's family self-priming pump, the flow should be chosen as small as possible; if users use the submersible pump irrigation, you can properly select a larger flow.
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:How to select the pump model?
Your vertical height is approximately equal to 190 meters, the actual line loss should be considered to be more than 200 ~ ~!How much do you need for traffic?Choose a suitable submersible deep well pump according to the flow rate! You can communicate in private!
Q:How to introduce water pump?
The so-called Practice makes perfect., read the three hundred Tang poems will not recite poetry.Suggest a good understanding of the basic knowledge of water pumps, industry trends, understand the needs of the industry, as an expert in the industry!
Q:What does the lift of a pump mean?
Simply from the local to the pumping pumping height calculation of rice
Q:The wiper pump is broken. How much will it cost to fix it?
This can not be repaired, can only be replaced, change a thirty or forty
Q:What is the reason that the centrifugal pump outlet pressure decreases and the operating current increases?
The reasons are as follows:(1) motor guide bearing wear, water pump rubber bearing wear, sealing ring wearMotor or water pump bearings wear, will make the submersible pump in the machine on the wrong state of work, serious damage to submersible pumps, stator windings burned. The method is to repair or replace damaged bearings and bushings.(2) thrust bearing wear, submerged pump impeller and lower cover wearThis situation will also make the submersible pump on the machine in an abnormal state of work, serious damage to the submersible pump. The treatment method is to check the cause of the wear of the thrust bearing. Whether the mechanical seal of the shaft extension is damaged or not, which causes sand particles and impurities to enter the inner cavity of the motor, causes excessive wear of the thrust bearing. If it is caused by the mechanical seal of the submersible pump, the replacement of the thrust bearing, thrust plate and impeller, lower cover plate and other parts shall be replaced by mechanical seals at the shaft extension end.(3) the flow of the submersible pump is too large or too smallThe use of submersible pumps flow beyond the scope of use will make the motor overload of centrifugal pump or mixed flow pump, excessive flow, the pump shaft power increases, the motor overload; for the axial flow pump, the flow is too small, the pump shaft power increases, the motor overload. The treatment method is to adjust the valve properly, reduce the flow rate of the centrifugal pump or the mixed flow pump (increase the axial flow pump), and make the flow of the pump in the normal range of use.(4) the shaft of the submersible pump is bent and the bearings are not concentricThis is a serious case of submersible pumps, should be immediately overhauled, straighten the bent shaft, replace the unqualified bearings, re assembled submersible pumps.
Q:How to determine the pump installation elevation, why should we determine the pump installation elevation?
Determination of pump installation elevation: the geometric height between the suction well level and the center line of the pump impeller, plus the hydraulic loss of the suction pipe, is the actual installation height of the pump. (notice: if the suction level is higher than the center of the impeller, it should be negative)To determine the water pump installation elevation reasons: general water pump nameplate on the "NPSH" value, the above calculation of the value must be less than this NPSH value, so as to ensure that water pump is not prone to cavitation.[NPSH] - allowable cavitation margin is to determine the conditions of use of the pump cavitation margin.
Q:Think of several households sharing a pump
Each contactor is connected with each power source in the main circuit, and the lower port is connected to the water pump;Control loop, only draw the wiring diagram of A households, households in other similar first power through the control switch in series contactor several other a normally closed contact and then enter the M contactor coil;In water, leading to various water pipes connected with the electromagnetic valve, and the solenoid valve are connected in series and the two contactor normally open contact is connected to the power supply;As long as one of the closed control switch, the pump will run at the same time, using his own power, and this is the other an open pump closed control switch of their own, will not work, the water will not go into his house, the family will not run electricity; only when the first home after closing the control switch second, if still closed control switch, water and electricity will automatically turn to him.Not understood, of course, that there is one drawback, if one is using a pump, a few other can not be used to solve the problems, it is not difficult, is that every installation of a water tank or like a floor, said each install a pressure tank on it
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
