Q:Installation position of check valve for water pump
Check valves are normally installed at the pump's exit position!Check valve, also known as check valve, the specific installation needs to determine the direction of the pipeline!If the pipe in the installation position is vertical, you can choose the swing type and pipe type!If the installation position of the pipe is horizontal, you can choose the lifting type!Lift check valve opens and stops at the fastest speed!The swing check valve has the least resistance!The pipe type check valve is mostly in the form of clip type installation, which is suitable for the place where the installation distance is not enough!
Q:Under what circumstances should we set up fire pool and fire pump room? Is it necessary to have a building?
Public construction property
Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
According to the horizontal distance of 10 meters is 1 meters lift, 200 meters is 20 meters and 5 meters height difference of 30 Mega elbow, pump head floating down 10%, should be about 60 meters.
Q:How many kinds of pumps are there? What are the advantages of soft start?
The starting modes of water pump are direct start, star triangle start, reactance start, soft start, step-down start and frequency conversion start.1, direct start, generally suitable for small power motors, generally only in the following 15kw pumps, cheap;2, the buck start is the star triangle conversion start, that is, the start is accelerated two times to reach the rated speed, generally in more than 18.5kw pump use, moderate price;3, soft start is gradually increased to the rated speed, the impact on the pump is very small, the price is relatively high, is generally 3 times the buck start;4, the highest frequency conversion is started, in addition to the advantages of soft start, but also can be set at any speed work, energy saving has significant effect.Advantages of soft start:1, the output torque of the motor can meet the requirements of the starting torque of the mechanical system, ensure smooth acceleration, smooth transition, and avoid the impact of destructive torque;2, the starting current to meet the requirements of the motor capacity, to avoid motor heating, causing insulation damage or burnout;3, make the starting current to meet the grid power quality related standards requirements, reduce voltage sag amplitude, reduce the higher harmonic content.
Q:Multi storey residential buildings also need to set up pressurized water pump room, direct water supply can not be?
Some water pressure is not enough, and since you are multi-storey, you need to add booster pump downstairs
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:Two pumps automatically switch start control circuit,
Can add time delay relay, the key depends on how much time the water is full, if you design is automatic, it is better to use the triode reliable,
Q:How do I know the pump pressure?
That is, the rated pressure minus the pipe loss, and then less inlet pressure (generally suction pump inlet pressure is negligible), that is the working pressure.The head of a centrifugal pump is also called the pressure head of a pump. It is the energy gained by the pump of the unit weight and the fluid. Pump head size depends on the structure of the pump (such as the diameter of the impeller, the bending of the leaves and so on, speed. At present, the pressure head of the pump can not be calculated accurately in theory, usually measured by experimental method.
Q:Pump performance parameters have three sets of data, how to understand the flow, lift, flow speed
Mainly expressed the ability of the pump, mainly as a basis for selecting the pump users.Lift represents the performance of the pump to boost water pressure. Such as the pump head H=38 meters, that the pump outlet pressure normal to 0.38MPa.The flow rate represents the water supply capacity of the pump. Such as 100 m3/h. The general flow pump design, and the corresponding flow, little significance.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Pump selection is based on flow, lift, power to determine, the actual situation is different, the choice of pump specifications and models are different, the key to your needs to choose.
