Q:How to maintain and repair the booster pump of pipeline pump?
4. install "0" ring, tighten the pump body and motor end cover with bolts. Notice that the clearance between the front cover of the impeller and the pump body is 20. 0.5 mm. The impeller inlet, the outer ring and the pump body ensure a certain running clearance.5. the disassembly order is the opposite.
Q:What are the main performance parameters of the pump?
The amount of liquid supplied by a pump in unit time. Volume flow Q, unit m3 / s. There is mass flow G, unit is kg / s.
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
Q:What are the general water pump failure, how to repair?
Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
Q:Advantages and disadvantages of canned pumps
The graphite bearing lubrication medium, make the operation less noise and manual, reduce maintenance costs; in recent years, bearing material added with silicon carbide SIC, super hard, life is better than that of graphite bearing.The vertical structure can be installed on the pipeline like a valve, the installation is convenient and quick, and the motor and the impeller can be drawn out only when the utility model is used, and the pipeline is not needed to be removed.The utility model can be installed and run with a shock absorber or a damping pad, so that the pump is less noisy at running time.
Q:Water pump does not produce water, what are the reasons?
1 check whether the motor is reversed.2, to see whether the export, the entrance blocked, the outlet pressure gauge whether there is pressure.3, whether the pump selection is wrong, you can not suck up the water.
Q:Constant pressure pump working principle
15MPa. 20MPa means that if you enter the 20MPa, the variable mechanism will work, and the flow at this time automatically matches the load. 20MPa used to supply the fuel by maximum displacement.
Q:What are the differences between the sewage pump and the clean water pump?
Sewage pump is a pump and motor conjoined, and at the same time submerged into the work of pump products, and general horizontal pump or vertical sewage pump compared to the sewage pump compact structure, small footprint.The water pump is for the transport of water and physical and chemical properties similar to water and other liquids used, suitable for the industry and the city water supply and drainage, water pressure high-rise buildings, garden sprinkler, fire booster, long-distance transportation, HVAC refrigeration cycle, irrigation, bathroom, cold and hot water circulation pressurization and equipment.
Q:Why is the sewage pump device coupler?
Advantages of installation and arrangement of sewage pump coupling:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device under the condition of fixed installation, such as pump fault maintenance personnel need to unscrew the screw pump lifting water, repair, or other small pump to pump the water down perfect maintenance, if the water is dirty, it would be difficult for people to go to the next, then the overhaul had great difficulty.
Q:What does the impeller on the centrifugal pump mean by the first cutting?
So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.
