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:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:Water pump maximum flow and standard flow?
The parameter standard of the pump factory is determined by its efficiency, that is, the efficiency of the pump is highest at that point. All parameters have two curves, that is, a flow curve and an efficiency curve. You can according to your standard flow, see how much the efficiency of the point, the maximum flow efficiency is how much will know.
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:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:Is the pump lift horizontal or vertical?
A vertical, vertical lift is one meter (see environment), usually 5~10 times the horizontal distance
Q:How can the pump be stationary?
1, the pump bearing lubrication interruption, bearing burn.2, locking the rotor is jam.3, foreign body corrosion serious impeller lock.
Q:How does a pump pump water?
Centrifugal pump is centrifugal force, and household deep well pump is primary pressure
Q:What is the difference between a sewage pump and a clean water pump? Why can't sewage be pumped with clean water?
The clean water pump and the sewage pump are different from the design. It also requires different material. Sewage pump requires material of solid phase friction, acid and alkali corrosion resistance, and other high resistance, and clean water pump can ignore these requirements. In addition, the sewage pump in a large proportion of large solids content of the fluid can also work normally, and clean water pump in the design can not meet the long-term use of this environment requirements.Of course, clean water pump can also be used for sewage, but only temporary measures, and the life expectancy, the effect can not be guaranteed.
Q:How to change the frequency of a water pump with a pump?
The water pump with frequency conversion is set correctly and will not burn the motor. If there is a problem, the frequency converter will automatically stop running. The frequency converter can change the positive and negative (frequency changer without this function, change the phase sequence)
