Q:Is the motor with a pump a squirrel cage induction motor?
Not necessarily, mussaurus main motor and conventional motor rotor winding is the difference of mussaurus, can be in series with other equipment, to achieve more functionality!
Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
Q:Fire pump control cabinet installation distance, ground height should be how much?
We know that the fire pump control cabinet has the distinction of floor and wall mounted, wall mounted control cabinet installation height generally is determined by the employer departments, without any special labeling, proposed control cabinet frame under the 120cm from the ground, this is the installation height compared to the commonly used, can be used for your reference.
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:Pump power ratio design is small, the problem is big?
No problem, despite the good use of different water pump factory manufacturing process is different, the product of the rich value of different factors, power difference is inevitable, as long as the flow and head to meet your use requirements.The calculation formula tells you: your flow is 72 tons / hour, lift 90 meters, motor power P=2.73HQ/0.75*1.2=28.5KW
Q:How many pumps does a 50 meter water head use?
Well pump head selection for pump + water depth height (water pressure) + head loss, head loss of water system is not complicated with 3-5 meters can, refers to the depth of pump well pump down into the well depth, generally shallow wells is down to the bottom, is based on deep well pumping well test data to determine the position of the pump.
Q:How can I pump the motor insulation?
A submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the electric box so that the pump shell shake shake, also must be reliable grounding to shake to now, the pump shell grounding not only in the water, it must be a wire connected with a shell or a wire will be immersed in water, this is right insulating shake,
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:What is the difference between a fire pump and a living water pump?
Fire pump and life pump essential difference, simply said: in the materialBecause we are used every day in the life of the pump, so there is no rust phenomenon, and the fire pump can not occur even in a hundred years to spend time, even some of the fire pump until life exceed the standard is not used, only periodically, so in order to prevent emergencies caused economic losses and personnel to design special pump different from the life of pump material as fire pump. Single stage centrifugal pump. The multistage centrifugal pump and pump life principle without any distinction, but the material will cast steel replacing 304, 309 stainless steel or copper materials, different specifications of other fire pump structure, materials should use copper and stainless steel.
Q:What does the temperature range of the pump mean?
Not be too cold or hot water, will be frozen.
