Q:What are the categories of pumps?
Did you say the pump voltage is 220 or 380?
Q:Fire pump room is required to set up water pump control room?
What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?
The high and low level values are set back.
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:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
It's better not to start directly. It's a great test for your motor and contactor. Do a star three start, conditional on doing a star three plus autotransformer start, reducing the starting current. Reduce future maintenance costs. Since do not think about every day to do pump repair.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
According to the water quality difference, the purpose is to provide the corresponding cooling water, for the system oil cooler, machine seal and other cooling. Open water directly from the circulating water pipe to use, the pump is delivered to the host, the small machine oil cooler, water quality is not very high, the circulating water drainage to the back pipe, water through the water filter filter impurities. The closed water takes the self closing water tank, which is used for removing salt water. General supply pumps, water pumps, sealing cooling water, condensate pumps, sealing water, generator, hydrogen cooler and other requirements of good water quality system, closed water self circulation, and through the cooler and open water circulating water heat exchange.Thermal power plant is referred to as the thermal power plant, is the use of coal, oil and natural gas as a fuel production power plant, it is the basic production process: fuel combustion in the boiler heating water into steam, fuel chemical energy into heat energy, steam pressure and steam turbine rotation, converts heat energy into mechanical energy and steam turbine rotate the generator, the mechanical energy into electrical energy.
Q:Why is the water pump smaller than the pipe diameter?
In order to reduce the water outlet resistance of pump outlet.The statement should be: if your pump has been selected, then the outer outlet pipe caliber than the water pump outlet diameter one.
Q:Diving pump voltage
Absolutely not, because 220V is not the same as the 380V waveform. Submersible pump single-phase motor is generally single-phase capacitor motor. The working principle is different from that of the single-phase 380 motor. If the power capacity is enough, it is recommended that you increase the wire (you can buy a line and go to use, to avoid waste), preferably with copper wire.
Q:30kW what is the flow rate of the pump?
There are many kinds of pumps, so it's difficult to answer you with a 30KW pump.
Q:What's the meaning of a single-stage pump?
I. meaning:Single stage and multistage refers to the number of impellers. Generally equal lift and flow, multi-stage pump than single stage pump power is low, that is, to save power, and high efficiency, long life.Two, how to distinguish?:Water pump said double suction refers to both sides of the water pump has suction port, and single suction pump only from the side of water absorption, single suction pump flow is small, double suction pump flow larger. The axial flow pump blade is a little like the blade of an electric fan. The axial direction of the axial flow pump is smaller, and the flow rate is relatively large, which is mostly used in the first stage pumping station of the water plant. JC is a deep well pump, with a large lift, but the flow is often not large. Centrifugal pumps are the most widely used at present.
