Simple structure, less cost, Submersible

Application

1

Ground water suction equipment

2

Water lifting in rivers, reservoirs and Canals

3

Agriculture irrigation

4

Water supply for human and animal in plateau and mountain area

5

Water drainage in city, factories, railway system, mining area and construction site

6

QJ Deep Well Pump Construction & Features


--- Compact vertical centrifugal multi-stage design with perfect standardization and generalization, easy operation and convenient maintenance.
--- A complete electric submersible pump includes a water pump set, electric motor, a discharge piping, water-proof cable and a control panel.
---Submersible motor filled with clean water for cooling and lubrication. And the pressure regulation switch, located at the bottom of motor, shall automatically operate to balance the pressure fluctuation caused by temperature variations.
---A sand slinger and oil-sealed skeleton are equipped at the upper part of motor to form a closed operating system for the motor, thus preventing any sand to penetrate into the motor.
--- Water injection hole as well as air release hole are designed at the upper part of the motor, and water release hole at bottom (lower) part.
--- Thrust bearing and collar are designed at lower part of motor to stand the weight of the squirrel caged rotor and the axial thrust residual.
--- Water-proof electromagnetic wiring for stator with excellent insulation.

Q:What are the export pumps packed in cartons?
Our exports are packed in specially made export special wooden cases. The water pump bolts are fixed at the bottom of the wooden box through the anchor bolt hole, then wrapped in plastic bags, and then sealed.
Q:Why does the GB/T3216 specify the pump performance tolerance as positive and negative?
Only half a year after graduation. Professional stuff is forgotten...I can't help you...
Q:What is the difference between self-priming and non self suction?
The self-priming condition of the centrifugal pump is that a small water tank is attached to the pump body. Don't use water every time you start. No suction, no water tank. And the use of volumetric Self-priming pumps, such as car cleaning, high-pressure pumps are in this category.
Q:What's the difference between a cold water pump and a hot water pump?
Cold water pump is generally packing seal, hot water pump is generally mechanical seal. If the cold water pump is used to transport hot water, the common trouble is that the shaft seal is easy to leak and the water pump is easy to damage. Generally in the design of building water supply and drainage, cold water pump and hot water pump can be selected according to the cold and hot water. Water supply and drainage design manual (common equipment) and pump manufacturers Water Pump samples can be found.
Q:What does the lift of a pump mean?
Lift lift height = water raise height = total lift lift height + water = water is expressed in M by H (m)
Q:How to identify the motor series of pumps
You can also use the motor speed divided by 50, equal to the motor series.
Q:How to measure the temperature of pump body?
Buy an infrared thermometer
Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
What should have Water Leakage place, check all the toilet faucet is Water Leakage, Water Leakage, water heater and so on, if no problem, to check the pump, which has a check valve, when the valve is broken, can not maintain the pressure, there will be the phenomenon
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:How many lift pumps should be used for 100 meters tall buildings?
35m lift around. HVAC pump lift is generally between 5~50m, the selection of the head is mainly to see the difference between water pressure. As head of 35m as an example, if the inlet height of 60m, so the theory of height =60+35=95m, if all pipe closed air conditioning water system, and resistance of the equipment for water is equal to the pressure difference is equal to the pump head to choose your height, and out of the water is the same, the resistance loss of lift all into the water. The calculated resistance loss is needed to pump lift. The resistance component (1) chiller resistance at 60-100kpa (2) water collector resistance in 120-200kpa (3) 20-50kpa (4) air terminal equipment body resistance is generally not less than 40kpa so 100m building the resistance calculation of estimated value = (1) 80kp+ (2) chiller resistance pipe, the collector resistance (140kpa+ 3) air terminal equipment 40kpa+ (4) body resistance 50kp=310kpa safety factor of 10% 320x1.1=341kpa H= P/ (head of pressure water density * acceleration of gravity g =352000/ (10m) X9.8 =34.8m fand) so we head for 35 meters
