Product Description:

Production outline
SLOW two stage/multi-stage split casing double suction pump is specially designed and manufactured by our company for using in the occasions which require large flow and high lift, such as iron works, electric power plants and pump station, etc. In combination with advanced design experience of two stage and multi-stage split casing pump at home and aboard, the products are processed by using special machine tool. This product is applicable for feeding such media as water or liquid similar to water at the temperature from -10 to 80℃.
Production characteristic
1Water inlet and outlet are all installed in pump body. Just hoist the pump cover when overhaul, greatly facilitating maintenance.
2.Primary-stage double-suction and secondary-stage single suction of impeller adopted, greatly improving anti-cavitation performance of pump and decreasing axial dimension of pump.
3.Rotary speed 1480 rpm, avoid vibration caused by high rotary speed.
4,In comparison with single-stage pump, the products have same performance and smaller impeller diameter and stable operation.
5.The pumping chamber adopts double-volute design, reducing radial force.
6.Applying rolling bearing and lubrication with grease or thin oil and facilitating the maintenance of bearing.
7.Designing in virtue of international advanced hydromechanics software, modeling by using 3DM software, and checking the strength with finite element software, ensuring high efficient, stable and reliable operation of pump.
8.Fully mechanical seal ensures no leakage within 8000 h,and packing seal is customizable.
9.The pump turns clockwise, and anticlockwise turning is customizable.
10.This product has applied for national patent (patent number:ZL200520046059.0)

Q:Why does the water pump leak?
The sealing ring is invalid
Q:What does the pump lift mean?
The pump head is the height or length of the distance from the pump to the outlet
Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Mgh=ptIn 1 hours30*1000*10*30=p*3600P=2500 (W)Therefore, the ideal state should be more than 2500W motorWith all kinds of losses, it is recommended to configure more than 3000W motors
Q:What will the water pump reversal situation?
The same will reverse pump water, but the head and the pressure greatly reduced, I just finished debugging a pumping station, Stephen multi-stage pump, installation of equipment: multistage water pump motor power 4 75KW 76% head 100 meters, frequency control, motor nameplate nominal current of 143. According to the direction of the motor steering pump mark OK set the start time of 28 seconds after 5HZ boot head start frequency can reach 50 meters (at that time did not install the pressure gauge cannot observe the water pressure of current) in early 118 about 3-5 minutes after the current is reduced to about 97, there are inspection found no problems, suspected pump problems, suspected foot valve not completely open, the reason cannot exclude the end of valve, almost in despair when the thought is not marked in the direction of the pump, re set to restart the current 129.5A to observe that later installed capacity reached 0.55MPa duct pressure gauge head close to the design requirements, the problem on the manufacturer's mark is reverse.
Q:Water pump part is stainless steel, which part is it?
An overcurrent unit is a part of a liquid that passes through a pump when it is in contact with the liquid. Such as pump body, pump cover, impeller, shaft, shaft sleeve, impeller mother, key and expansion tube, etc..
Q:Pump flow 6M3/H is an hour, how many tons of water?
=1 tons of water 1M3So 6m3/hIt's 6 tons / hour
Q:Power flow conversion of water pump
Upstairs in Wurenzidi, pump power is related to the flow and the head, a simple formula: = /367 * power flow lift efficiency
Q:What's the meaning of a single-stage pump?
In fact, the simplest difference between multi-stage pumps and single-stage pumps is that more than one impeller and one impeller can be summarized.The so-called single-stage pump is the pump inside only one impeller pump, so that we can be referred to as a single-stage pump, which is characterized by the head is not high, but the flow rate could reach thousands of square per hour, the typical model is the ISG type single-stage centrifugal pump.The pump is a pump body which contains a plurality of impeller pumps, pump is characteristic of such a large flow and high lift, traffic can be thousands of square kilometers to the head, but the cost is not low, customers should be chosen according to the actual parameters.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The vacuum meter is used to measure the vacuum degree of the water pump before the water pump pumping, and to a certain degree of vacuum, the water can be sucked into the upward pressure position of the pump.A pressure gauge is used to indicate that the pumping is pressure in the pipe. The size of the pressure is related to the lift head, pipe diameter, atmospheric pressure and so on.
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Look, the direction of the motor is the direction of that arrow. Point to the other side. That's the water out
