Q:What is LG water pump?
LG water pump refers to high-rise building feed pumpThe water pump in high-rise building adopts vertical and sectional structure, and the operation is safe, stable, long life, small occupation area and convenient installation and maintenance.Two, product features:1, compact structure, small size, small footprint.2, replacement of vulnerable parts (mechanical seal) convenient, that is, "demolition" without dismantling the motor.3, assembly without adjustment, overhaul, convenient maintenance.4. Radial force and axial force are balanced by hydraulic force, and bearing is combined.5 、 noise and vibration are small and the operation is smooth.6. The main wear parts are made of high quality wear-resistant material.7, can be equipped with the same type of ordinary motor.8 、 mechanical seal special design, good sealing, life enhancement.9, using the hot water type mechanical seal, water can be pumped.
Q:What is the water pump population pre rotation, what harm?
The turbulence formation flow entrance, the flow direction is complex, impact, vibration, easy to damage the device before; if there is no water pump entrance pre swirl design will affect the safety and service life of equipment.
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:Submersible pump and self-priming pump which is easy to use?
Pump generally installed at less than 7 meters from the water surface, if not meet this requirement, have to use submersible pumps, such as deep wells. Submersible pump is obviously not good, easy to malfunction, have to use.Self-priming pump is mainly convenient, but the performance is lower than the general centrifugal pump.There are both advantages and disadvantages at the same time, which is not easy to use.The key is where to use and how many parameters............
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
As long as the flow and head to meet what pump can be, the general centrifugal pump applications are more.
Q:The car water pump is broken. What are the symptoms?
Car water pump damage, water temperature will rise sharply
Q:How can I pump the motor insulation?
The cable head in the distribution box should be relieved. What's more, the motor insulation is not the pump insulation. Usually, just shake it in the middle of the water and the ground.
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump
Q:Does the pump accessories have a shelf life?
No, they don't have a shelf life before and after the sale,Before selling, it is infinitely long, and there is no expiration date after the sale
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The home pump does not turn, but the motor is energized:A: there are heard buzzing, but can not move and no death card. It is likely that the boot capacitor is broken and that the capacitor can be measured with a universal meter.Two: if the motor is sure to have electricity, check whether there is low voltage or broken phase (three-phase motor). These conditions also cause the motor not to rotate, or the speed is low (easy to block), so it should be measured with a universal meter.Three: you can smell there is no burning flavor, may be motor winding interphase short-circuit. Bearings should be hard to break, and it's probably not good to find repairs.If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter. If the capacitor is damaged and does not know or can not see the mark parameter, it can be calculated and matched according to the following formula:In C=8JS (F), the capacitance of the C- is S- (F). The current density of the starting winding of J- motor is generally selected from 5 to 7A/ (mm) 2, and the cross section area (mm2) of the starting winding winding. Generally, you can choose 1000W/40 F.
