Q:What are the categories of pumps?
Did you say the pump voltage is 220 or 380?
Q:What's the difference between a double suction pump and a single suction pump?
From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
Three in one pump with a hose connected to the oxygen pump as the pipe above the water so that the air will enter the pump, you can spit bubblesYou put it too deep and put the hose into the water too. Without air, you can't spit bubblesIf the pipe is not long enough, you can find a hose for the oxygen pump instead of a long tube, with the hose out of the water and fixed
Q:Can the water from the fire pump enter the roof fire tank? Why?
Here is the concept of "fire water tank", if the roof has fire water tank, fire pump should be able to roof fire water tank water supply, as long as there is sufficient pressure on the line. However, if the roof water tank is only a living water tank, the fire pump is not started, this is the two pipelines.
Q:50 meters deep well with what water pump: home?
For deepwater submersible pumps, ordinary submersible pumps are inefficient.
Q:Does the lift of pump relate to the water level of import and export?
What's the relationship?! When the inlet level is low, the head is slightly higher than the liquid level!
Q:How to introduce water pump?
The so-called Practice makes perfect., read the three hundred Tang poems will not recite poetry.Suggest a good understanding of the basic knowledge of water pumps, industry trends, understand the needs of the industry, as an expert in the industry!
Q:How much is the flow rate of fire hydrant and spray shared water pump?
Fire fire water is superimposed, at the minimum, the lowest 5L/S automatic spraying fire hydrant, light danger level 13.9L/S, the least is 18.9L/S, but the data is useless, the data are not spraying fire hydrant, concrete analysis of high-rise buildings like the dangerous level according to the calculation, the general design, the concrete building needs the high-rise building minimum 20L/S, automatic spraying dangerous level according to the general 30L/S, 50L/S need to flow.Fire hydrant: fire hydrant (English Name: fire hydrant), a stationary fire fighting tool, with 4 iron chains. Fire hydrants are provided throughout the city to provide fire water for firefighters during the rescue. The main function is to control fuel, insulate combustion and eliminate fire source. The fire fighting system includes outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some automatic sprinkler system, water gun system, gas fire extinguishing system, fire detection system, water mist system and so on. Hydrants are mainly fire engines from the municipal water supply network or outdoor fire water supply network to implement fire fighting, but also can directly connect hoses, water cannons, fire extinguishing. Therefore, the outdoor fire hydrant system is also one of the important fire fighting facilities.
Q:Water pump mutual switching device
Now fire control cabinet has several requirements, multi-channel start, failure switch, automatic inspection, etc.Failure switching is when the main pump fails to start, the standby pump is put into operation automatically (and the two pumps are alternate).Mutual investment due to the original selection of different electrical principle is slightly different, but the same is the control of the main contactor, the main contactor when the main pump without electricity and suction time, time relay (or PLC fault detection delay is given by the pump start signal delay conversion) pump operation.You'd better find a fire drawing study.
Q:What is the relationship between pump power, lift and flow?
N= QH/1000 gamma ETA gamma, severe liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / sec.
