Q:Fire pump room is required to set up water pump control room?
You can't set it up.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.Fire pump for fire as the name implies, pump, fire pump is the introduction of foreign products, according to different classification, divided into different types to its sealed, no leaks, corrosion-resistant characteristics, widely used in environmental protection, water treatment, fire departments for pumping all kinds of liquid, no leakage, no pollution is to create civilization workshop civilization, the ideal pump factory and pump type fire control system are similar, only the head and the flow are different. The selection of fire pump should be based on the technological process, water supply and drainage requirements, from five aspects to consider. Fire pump performance and technical conditions meet the requirements of the Atlantic pump standard "fire pump performance and test method" standard.
Q:25KW what is the lift of the pump?
Give you a formula for estimating the power of a pump:N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85Explanation is:N, the power unit is kW (kW)Q, flow, in units per liter (L/s)H, the lift is m102 is 1000/g, G, that is gravity acceleration, is a unit conversion0.6~0.85, the efficiency of the pump, the general flow of large values, small flow of small value;0.85, power factorIn addition, there are some general power pump module, since there are: 1.1kW, 2.2kW, 3kW, 4kW, 5.5kW, 7.5kW, 11kW, 15kW, 18.5kW, 22kW, 30kW, 37kW, 45kW, 55kW, 75kW, 90kW, 110kW, 132kW......And generally there is no 25kW pump.
Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
It burns and seals when idling. The individual thinks that it can be indirectly reacted according to the pressure change in the pipeline, and the electric contact pressure gauge can be installed on the suction pipe
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
Strictly speaking, eleven kilowatts or more is not allowed to start directly
Q:TDH what units are present in the pump parameters?
TDH, Total, Discharge, Head, that means the head, the unit is usually feet. 1 feet =0.3048 meters.
Q:Power flow conversion of water pump
Pump shaft power (kw) = water supply (L / s) x lift (m) /102 * efficiency = flow * lift * density * acceleration of gravity.Explanation:102 is the unit collation constant.Pump effective power / pump shaft power = pump efficiency (general 50%--90%, large pump higher)Unit time pump liquid volume flow is, flow by Q, a unit of measure: m3 / h (m3/h), L / S (l/s), L/s=3.6 m3/h=0.06 m3/min=60L/minG=Q G refers to weight - liquid proportionThe energy obtained by pumping a liquid of a unit weight is called a lift. The pump head, including suction stroke, is approximately the difference between the pump outlet and inlet pressure. The lift is expressed in H, and the unit is m.The efficiency of a pump is the ratio of the effective power to the axial power of the pump. ETA =Pe/P pump power usually refers to the input power, the motive power to the pump shaft, it is also called the shaft power, denoted by P. Effective power is the product of pump head and mass flow and gravity acceleration
Q:Water pump is not Sheung reason
The problem you are experiencing is stressThe above answer is only considered in the case of water absorptionJust imagine, two pumps are normal work, the same suction pipe, how can there be dissatisfaction with water or vacuum state?.According to my experience analysisYour system is three sets of parallel, lift and flow should be the same, if not the same, not in this discussion, the topic should be set up.Lift is the same, that is, in two or three units at the same time, the resulting system pressurization is the same, and water will increaseBut now your traffic is increasing at two units, but it will not increase at threeYou have selected pipeline system design, in the design of head flow under single condition is constant, if the increase in open water pump, the pressure is constant, increasing water content, according to the continuity equation Q = A X V, then the flow velocity in the tube will increase;But when the third pumps, 2Q becomes 3Q, normally velocity should be larger, but the Darcy formula shows that the velocity increases, extension resistance and local resistance will be increased, and the double square, so you can open third pumps for reasoning, when the resistance effect caused by the pipeline the increase of water flow in the pipeline can not be reused, the general formula of constant current, now the whole pipeline in turbulent stateThat is, third pumps to do the work in the water and pipe wall friction in the loss, and actually did not play a role in water supplyThe solution is to increase the flow rate by increasing the water supply pipeline
Q:Pump adapter belongs to the system of fire pool equipment?
Does not belong to the fire pool system! Pump adapter is mainly used for fire engines through the adapter system pressure, outdoor fire hydrant fire with one hand, one hand is to provide water for the fire truck. According to the 10~15L/S calculation of each pump adapter
Q:Think of several households sharing a pump
If you want to share the electricity bill, but also to pay their own, but it is difficult ~ but we can change the way ~!First of all, we use a pressure tank or a water tower to let it water automaticallyAn electric meter is installed on the water pump to measure its total power consumption ~!Then each household installed water meters independently and measured their water consumption ~!Then, according to the amount of water consumption, according to their respective proportion of electricity charges ~ but this cost is higher ~!
Q:How to change the frequency of a water pump with a pump?
I have encountered this problem, 1, check the reverse pump outlet single flow valve is damaged2. Check whether the three wires of the motor are in wrong position and reverse when starting
