Product Description:

Deep well submersible electric pump is a direct mounted pump combining the motor and pump together. It can be used as water suction equipment for groundwater, river, reservoir and canal etc. This pump is mainly used for agriculture irrigation, water supply for human and animal in plateau and mountain area, and water drainage in city, factories, railway system, mining area and construction site etc.

Q:Can centrifugal pumps be idle? What's the status of the empty transfers?
The centrifugal pump can not be idle, idle will wear packing (packing seal, mechanical seal is almost not damaged) parts, also caused the seal ring, seal, etc. the balance disc wear quickly, and the temperature will rise sharply, causing damage; air transfer effects caused by transient overload voltage of the motor is large, if the motor can not automatically jump to motor will burn.Centrifugal pump mostly rely on the delivery of liquid lubrication and cooling seal of centrifugal pump, idling is empty load, is to open the inlet valve, close the exit valve operation can move, try reversing or empty load operation should be based on the inevitable time, pump specification shall prevail.
Q:TDH what units are present in the pump parameters?
TDH, Total, Discharge, Head, that means the head, the unit is usually feet. 1 feet =0.3048 meters.
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:Pump flow 6M3/H is an hour, how many tons of water?
Flow 6M3/H, that is, an hour can smoke 6 tons of water. But according to the power, head and flow calculated by formula, the water pump efficiency is 98%, can it be achieved?
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
Not sure about the LZ what is the specific type of hot water pump pump but it is flow and small pressure must be produced liquid vaporization of liquid vaporization two general situation is the pump pressure alternating is under positive pressure immediately into negative pressure is two high temperature liquid into the pump and to absorb mechanical heat due to the higher temperature is the centrifugal pump if so when the liquid from the inlet to the outlet end of the impeller is thrown when in the state of negative pressure and lower boiling point even if did not reach 100 degrees will boilIf the water pressure and flow rate of small vaporization significantly not only reach the requirement of the pump itself also has a lot of damage caused by mechanical damage is suggested to view the instructions to use if this situation is to contact the dealer in the allowable range of temperatureIf no water is not only the problem of vaporization conditions can be detected under normal pressure inlet check instructions when pumps are used in the allowed suction height within the position and I don't know if the pump there may be no open suction valve or discharge valve and pump parts prior to use at the beginning of irrigation is the first inside in order to produce self suction irrigation
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.
Q:Pump impeller diameter plus assembly what changes? What's the effect on the motor?
Two item 1.5 kilowatt type self suction pump original impeller 14.7cm installed 15.5cm may be a problem.After the impeller increases, the flow, head, shaft power will increase (increase in volume see the following formula), the original 1.5KW motor may overload operation.The larger the diameter of the impeller, the greater the lift, the greater the flow rate, because the flow rate of water depends on the centrifugal force generated by the impeller rotation and the line speed on the tangent. The greater the diameter, the greater the centrifugal force and the linear speed. The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment. Vacuum pumping or vacuum pumping two times.The vacuum of the inlet of the centrifugal pump is composed of three parts (the equation of the inlet of the pump and the level of the suction liquid).
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Pump selection is based on flow, lift, power to determine, the actual situation is different, the choice of pump specifications and models are different, the key to your needs to choose.
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:What is the relationship between pump power, lift and flow?
When the power is constant, the kinetic energy theorem is known as P=F*V, that is, W=F*S.In the water pump, it is said that the work done by the unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
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.
