Type SA pumps are single-stage double-suction centrifugal pumps with horizontally split casing. The pumps are suitable for pumping clean water without solid particles or other liquids whose physicochemical property is similar to that of clean water.

Capacity: Q:90m³/h~7200m³/h

Head: H:9.5m-104m

Temperature: T≤80℃

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: According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion

Q: Troubleshooting of diaphragm pump: The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture

Q: Variable flow pumps are variable pumps: Yes. The variable pump is designed to change the flow rate

Q: What are the functions of a disposable infusion pump?: This is a very professional question, ha!I only know disposable infusion pumpsAttached: intelligent medical infusion pump and its application

Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?: What will happen then? The aquarium glass is an insulator. The water in the fish tank has the same potential as the live wire, and the fish is like a bird standing on the fire line. No electricity flows through their bodies, so they won't get electrocuted. But if you put your hands into the water, you will get an electric shock, because the line voltage through the water, then your body and the earth to form a loop, current flowing through your body you will get (of course, if you stand on the insulator does not get an electric shock)

Q: What does "efficiency" mean in a water pump catalog?: Pump efficiency: the ratio of the effective power and the pump shaft power

Q: How high can the pneumatic diaphragm pump be?: If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.

Q: Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.

Q: What is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?: The unified corrosion resistant design of bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more severe applications;

Q: Which nuclear submarines use the shaftless pump technology?: The team led by academician Ma Weiming of China is now carrying out the research on this technology and has achieved initial success.. This technology is expected to be applied to the next generation of domestic submarines.
