Product Description:

Single-Stage Double Suction Water Pump for Irrigation

1.Structure of Single-Stage Double Suction Water Pump for Irrigation Description

End Suction Centrifugal Pump complies fully to the European Standard BS EN733 / DIN24255 of performance and dimensions. They are used for pumping clean water or liquids similar to water, achieving wide application on plants, mines, city water supplies, air-conditioning coolers, firefighting system and irrigation. Pumps of the same model have different performance levels basing on different diameter after impeller trimming. Overall the whole series, there are only four sizes of shaft and five of bearing housing. As long as their bearing housings are of the same size, different pumps can interchange chief parts such as shaft, shaft sleeve, shaft seal, impeller nut, etc.

End Suction Centrifugal Pump is also very easy to be installed and maintained. Back pull-out design, driven through flexible coupling, so that pump casing and motor can remain in position while other spare parts are removed.

Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
Q:What does "efficiency" mean in a water pump catalog?
Pump efficiency: the ratio of the effective power and the pump shaft power
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:How long does the fine stone pump need maintenance? What should I pay attention to?
Daily maintenance of concrete pump, that is, routine maintenance in use, including inspection, cleaning, lubrication, fastening, adjustment, leak hunting, supplement of hydraulic oil, etc.. 8.1 hydraulic components inspection, due to the complexity of the equipment, we recommend practical experts to carry out the inspection of hydraulic system. If a fault is found, check the cause and repair the entire loop before proceeding to any operation. - found that oil has diarrhea, excluding leakage reasons. - inspect safety valves, hydraulic systems, steel tubes and hoses, fittings, cylinders, and find any wear and tear (pipe explosion may cause very serious consequences)
Q:How is the pump level of submersible sewage pump determined?
Pump water level must be higher than the water pump top, so that the motor running in the lower water temperature cooling environment, otherwise long-term operation will burn the machine
Q:What happens when a centrifugal pump is selected?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q:What are the problems that should be paid attention to when using vacuum pumps?
(14) vacuum pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.(15) the vacuum pump has been disabled for a long time. All the pumps should be taken apart and dried. The rotating parts and the joint should be coated with grease and properly preserved.
Q:What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
Q:Any center of the pump
Alignment methods and requirements:1, check two feeler dial gauge or flange coupling the parallelism, usually with clearance between the both ends of the side instead of difference, in the circumferential direction every 900 measure, the maximum and minimum gap gap difference (Ab) less than or equal to 0.3 mm.2, the coupling flanges outside the park up and down, left and right four position to check whether they are in the same line, C less than or equal to 0.1 mm.When looking for a positive C, it will affect (a - b), finding the right (a - b) will affect the C, to balance each other. It's easier for an unskilled comrade to find C (a - b) first, and then find a positive one. Through the adjustment of the motor at the foot of the gasket thickness (Ab) and meet the requirements of C.Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition.It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Q:What is a water pump coupling device?
The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
