Q:What are the parameters of the pump price?
First, the brand, brand sound, the price needless to say, second, material, stainless steel and cast iron, of course, not the same priceThird, the size of the motor, the motor determines the parameters of the pump, not motor power, and also imports and domestic.
Q:The flow of the pump will be reduced, the speed will change, the power of the motor will change?
Water pump flow rate, speed will not change, the power of the motor will change in general.Different types of pumps have different flow power curves. Only the most common centrifugal pump is used as an example to illustrate the relationship between the flow rate and other pump parameters. The typical centrifugal pump flow power curve is shown in the P-qv curve (red line) shown below.Turn left and turn right |According to the flow power curve, it can be seen that with the increase of the flow rate, the power increases linearly, and the power decreases linearly with the decrease of flow rate.In fact, the pump shaft power P= P gQH/ (1000 K), including H: head, unit m, Q: flow unit m3/s, ETA: for the efficiency of the pump, general 0.7-0.85, P: shaft power, unit kW, K: matching coefficient, small power is 1.25, P: work is like a water medium density.Therefore, for a specified pump, the power is proportional to the flow theoretically. In fact, as the flow rate changes, the efficiency of the pump changes, so it can only be close to the positive proportion.Running water pump speed generally depends only on the pump, power (motor, diesel, etc.) speed, the flow of water generally can not affect its speed. But in the design of pumps, the flow is related to the speed, and other design parameters remain unchanged, the pump speed is high, the pump flow.
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The motor is sure of electricity, isn't it? Is there a low voltage or broken phase (three-phase motor), these cases will cause the motor does not turn, or low speed (easy to block), so should be measured with a universal meter. Maybe the boot capacitor is broken. Or smell the smell of burning. It might be a short circuit between the motor windings. (bearings should be hard to break). Look for repairs if you suggest. You may not be good. Oh, capacitor. You can measure good and bad with a universal watch. If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter.
Q:What is the difference between self-priming and non self suction?
Non self suction is the ordinary water pump for the water inlet pipe, but the flow of water is small,Self suction for the water inlet no water (that is, 4, 5 floor water, no water on the 6 floor), it uses the principle of negative pressure to suck up the water
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
Water pumps are generally centrifugal pumpsThe circulation pump depends on what kind of liquid it is circulatingGrease is generally gear pumps
Q:The difference between submersible pumps and centrifugal pumps
Submersible pump refers to the installation of pumps in the form of motor and pump body are installed underwater. It can be a sewage pump or a clean water pump or other purpose.Sewage pump to see the name will know, that is, playing sewage, you can use submersible pumps, you can also use other forms of pump.
Q:Diving pump voltage
This is the reason why the line is too long and the power consumption is too large
Q:Pump adapter belongs to the system of fire pool equipment?
Not belong to. They all belong to hydrant water supply system.
Q:What is LG water pump?
LG pump LG refers to the name of the water pump brand, not on behalf of practical significance.LG pump is a high-rise building feed pump.1, LG, LG-B type of high-rise building water supply pump is a vertical multistage type structure, bolt the inlet section, the middle section of the water pump are fixed together, each containing a impeller and the guide vanes, the axial force of the hydraulic balance, the residual axial force by one or a pair of ball bearing;2, the shaft seal adopts special design mechanical seal, so when dismantling mechanical seal, do not need to remove the motor, the middle casing coupling can be removed from the seal, it has the advantages of replacement and convenient maintenance;3, pump transmission is through the shell coupling, vertical motor drive, from the motor side to see, the pump clockwise rotation;4, the suction inlet of the pump is below, the water outlet is above, and its relative position can be chosen according to the user's requirements, 0 degrees, 90 degrees, 180 degrees, 270 degrees for assembly, factory. General pump 180 degrees factory.5, assembly without adjustment, easy disassembly;6, the motor can be equipped with standard Y series of ordinary models.
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.
The company is always devote to innovation and management after founded more than 20 years. The company embarked on the road of a virtuous cycle and operating in scale. The company has professional pump design and developing technicians. And formed a manufacture management, quality management and marketing management system.
