- Q:Domestic pump does not use water, or turn, I do not know why?
- The motor should be kept working, may be the motor switch problem, idling motor pump long time will certainly be bad, ha ha, the solution is to find a water pump maintenance master to work safety first!
- Q:Pump adapter joint net outside tube, what is the principle?
- At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
- Q:Relationship between power and flow of sewage pump
- If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.
- 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:Water pump motor overload
- If the power line is too long or too small, power line is too long or too small will cause excessive current. Valve shut down certainly affect the flow. When the valve is in the semi open state, the water pump out of the water flow down, the power to reduce, so the current drops.
- Q:What is a variable frequency water pump? What's the difference between a variable frequency pump and an ordinary pump?
- Variable frequency water pump refers to the motor, variable frequency pump should be driven by variable frequency motor pumpFrequency conversion, that is, adjustable frequency, frequency conversion motor is able to adjust the speed, adjust the flow, to achieve the purpose of energy saving, but also start small current, maintenance advantages of small workload
- Q:Two pumps automatically switch start control circuit,
- Can add time delay relay, the key depends on how much time the water is full, if you design is automatic, it is better to use the triode reliable,
- Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
- The little air hose is had to pump in pump operation, to play the role of oxygen, generally want to let the oxygen hose head above the water, or to go into the air, and lose the function of oxygen, if the tank is large enough, every day to open the filter pump. Use hose plus oxygen does not matter.
- 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
- Q:What is the relationship between pump power, lift and flow?
- The pump power is more marked discrepancies in the actual application, power flow, power and small traffic hours, head directly determines the flow, high lift flow is small, the power is small. This view is the largest public understanding of the subversion of the original. I 1.1KW a self suction pump the actual operation of the power, it is able to explain this, 1.1KW would say 1.1 per hour of electricity, but I made a note of the meter, the per hour only 0.6 degrees, no wonder people say the true power of pump not so much, such as 1.1KW, said to be only 750W this is true, I believe. The rated power of pump or need to reach the normal traffic to its go to this value, or is the virtual standard, industry inertia. I put the home pump is pumping, water is two hundred or three hundred meters away a shallow river, because of the long distance, flow Volume is not very large, basically only rated 1/3 bar, and I do not know is the flow of low power consumption reduction, or the actual power of the pump did not mark that big, it is still under exploration...
