It's features are simple construction, easy operation, well moving, convenient repairing, high displacement, high efficiency and wide application slope etc.
- Q:About how to calculate the pump installation height?
- See the design manual, town water, volume P312This formula is: NPSHA = HgHzhsZs > NPSHRAccording to the actual installation of NPSHA pump cavitation can provideThe pump NPSH provides NPSHR pump samplesAtmospheric pressure Hg pump installation siteHz liquid under certain temperature saturated steam pressure.The head loss of water pipe HsThe installation height of ZsIt is worth pointing out that, with regard to Hz, with temperature related, and some problems are not given temperature, and that value is also very small, in the calculation should be able to ignore (0 degrees C, 0.06mH2O).And atmospheric pressure, we usually use 10mH2O, in fact, and altitude also related. When the altitude is 0, it is 10.3
- Q:Does the water pump and the circulating pump belong to the centrifugal pump?
- Water pumps are generally centrifugal pumpsThe circulation pump depends on what kind of liquid it is circulatingGrease is generally gear pumps
- Q:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
- The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
- Q:What motor does the pump use?
- Hello, the pump is generally used permanent magnet synchronous motor, and if the motor is not too understand, you can consult the motor suppliers, according to the model to choose their own use.
- Q:Is there a water pump with its own flow regulating function?
- Pump with adjustable flow depends on your useThe ordinary displacement pump, which has a small flow rate, can set the flow rate per second into the system and is widely used in the laboratory.Large flow regulating flow pump is mainly variable frequency pump, through the electrical signal feedback regulation, change the pump water storage flow.The main thing is to see your flow, and then determine what you want to pump!
- Q:Water pump maintenance what should be maintained?
- Bearings, seals, impellers - removing dirt
- Q:How do I calculate the power of the pump?
- Power P (kw) =9.81*Q (second cubic meter) *H (head, unit m) / efficiency;The efficiency can be found on the pump nameplate or sample.This is the rated power, if the head down, the flow increases, the power will increase, so the actual motor power is often much larger than this calculation.Generally buy pumps are equipped with motors, manufacturers can refer to the same model or similar models of motor power.
- Q:Do you need a stop valve for the pump at home?
- It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
- Q:Relationship between pump voltage and lift?
- This is the world's Grundfos pump, if the pump itself support work under the 414V if it didn't need to worry about traffic and Yang Cheng, if the pump does not support the long time operation of the pump must lift and flow impact, and the multi-stage pump if it is Gao Yangcheng in the use of low lift it is also easy to burn the motor,
- Q:Ask the principle of fire truck and pump adapter
- Fire engines have their own hoses. I've seen them. They usually have hydrants. They take water from them. If they don't work, they have their own water
