Q:37KW how many contactors does the pump need to start directly?
Direct start requires 250A contactor.Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to power, power distribution and power consumption. Contactor broadly refers to the use of coils in industrial electricity that flow through the current to produce a magnetic field, so that the contacts are closed so as to control the load of the appliance.
Q:How should the water pump breaker be selected?
Schneider circuit breaker is not selected, I do not know how much current to drive the 11kw pump, and there is no other load?
Q:Water pumps are always pumping water, what's the matter?
Is the self-priming pump, not the self-priming pump, the actual suction is too large?How much is the water pump voltage?Inlet pipe leak
Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump.The procedure is to start the fire pump - turn on the return pipe - return the water to the pool.The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.For every hour of the 2m flow fand self-priming pump, a spray gun flow is obviously too small, forced to use the pump load, affect the service life of the water pump.Add a return pipe, split water pressure, the problem is solved, adjust the flow of the return pipe, you can adjust the size of the spray gun pressure.If the spraying, the return pipe also plays a full stirring role.
Q:30kW what is the flow rate of the pump?
Estimated traffic: Q = nP/ (9.8H), =70%*30/ (9.8H), =2.14/H (m^3/s)It is estimated that the efficiency of the water pump unit n=70%, power P to kW as a unit, the head H to m as a unit, you go to check the head H is how many meters, into the formula can be considered the flow rate is how many cubic meters per second.
Q:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The vacuum meter is used to measure the vacuum degree of the water pump before the water pump pumping, and to a certain degree of vacuum, the water can be sucked into the upward pressure position of the pump.A pressure gauge is used to indicate that the pumping is pressure in the pipe. The size of the pressure is related to the lift head, pipe diameter, atmospheric pressure and so on.
Q:Safety head of water pump?
In fact, to prevent pipeline errors, generally take 0.5 meters margin, just in case the pipeline changes, resistance, and do not smoke Sheung Shui
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump power is small, the weight is limited, the pipeline vibration is limited, the general rubber shock absorber will be enough. It's no use. I'm sure you can't use the spring shock absorber.General construction, 7,5KW below is rubber shock absorber, above is spring shock absorber
Q:Pump pumping small is what happened?
Water pump pumping is small because of insufficient water source or pump head is not enough. At the outlet stop to measure the pressure, if there is a certain pressure, that is, the flow is too small, if there is no pressure, that is not enough head, or both small.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on.
Q:Water pump maintenance what should be maintained?
1 by sound to determine whether the bearing is good. If the sound is abnormal, replace the bearing.2, check whether the impeller is worn, if worn, will affect the flow, lift, efficiency, need to be replaced.3, check whether the mechanical seal can continue to use, can not be used, need to be replaced4, check the oil tank is missing oil, such as lack of oil to the appropriate location.
