Product Description:

<1>Outline :

IS series single-stage end-suction (axial intake) centrifugal pump is an energy-saving pump designed by teamwork in the whole nation, it is improved on a basis on model BA, B and other single-stage water centrifugal pump. The advantages: its hydraulic capability is distributed reasonably, wide option for user, conveniently check and repair, the efficiency and throw is up to advanced international level. This pump is suitable for industrial and city water supply, water drainage, and widely used for agricultural irrigation, transportation pure water or other liquids whihc physical and chemical nature is similar to pure water, and the temperature should not be higher than 80 .

<2>Features:

1)Speed: 2900RPM and 1450RPM;
2)Suction: 50~200mm;
3)Flow/Capacity: 6.3~400m3/h;
4)Head: 5~125m.

<3>Application:

a)Municipal water supply and drainage

b)Water circulation of air conditioner

c)Agriculture hydraulic engineering,such as irrigation,drain flooded fields etc.

d)Industrial water supply system,fire fighting system,drainage of heating system.

e)Transport of clean water or liquid of which physical chemical properties similar as water

<4>Construction

1. IS series single-stage end-suction centrifugal pump is designed ac cording to the capability and size stipul ated i n the internati onal Standard ISO2858, it is composed of pump body,pump cover, impeller, shaft, ring seal, sleeve and suspended bearing units.

2. The pump body and pump cover in IS series are separated from the back of impeller, that is to say in general, back open structure, whose advantages: convenient overhau l,when checking and repairing, the pump body intake pimp,discharge pipe and motor need not to move, just disassemly the middle connector of extended coupling to quit therotor units for overhaul.

3. The pump shell (that is pump body and pump cover)forms the workroom of pump. Impeller, shaft and rolling bearing are the rotors for the pump. Suspended bearing units support the rotors in the pump. The rolling bearing stands the radial load and axial force.

4. In order to balance the axial force of the pump, most of the pumps are designed with sealing rings at the front and back of impellers and a balance hole on the rear impeller cap plate. The reverse of impeller is not designed with sealing rings or balance holes if pump axial force is not powerful.

Q:A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: Such as a large pressure of about 10m or about 0.1MPa} because the most unfavorable point fire hydrant requires more than 0.07MPa (7m) and 0.5MPa (50m) is not greater than the pressure, so unless the pump is located in the 50m Valley is still lower than the garage, or add to the valve (or the use of fire hydrant decompression) otherwise, it is 120m lift pump

Q:How many square cables does the submersible pump for 7.5KW need?: According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.

Q:Does the control cabinet of the fire control pump need to be related to the fire control room?: Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.

Q:The distance from the pump button to the ground: A button is arranged on the surface of the fire hydrant button, and when the fire hydrant is started, the press button can be pressed directly, and the red starting indicator light of the fire hydrant button is on

Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?: In order to make the pump full of liquid, usually in the valve installed at the bottom of the filter screen along the suction pipe, the valve until the end against the valve, strainer prevents the solid material into the normal operation of the pump impeller damage or hinder the pump.

Q:Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?: The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.

Q:What are the meanings of the vacuum pump, the front pump and the main pump?: The main pump and the front pump with the general vacuum unitThe front pump can be understood as a mechanical pump. It can be used by itself, but the pumping rate or the vacuum can not meet the requirements. In this case, we add a booster pump

Q:Metering pumps related matters: 1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal

Q:How to adjust the flow of piston pump?: The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.

Q:Is the flow meter in front of the pump or after the pump?: Agree upstairs. Pump should be straight before the paragraph, 15 times the nominal length of the caliber.
