Product Description:
Application:
It is suitable for offshore platform fire-fighting, thermal dissipation, seawater desalinization, seawater lifting, coastal square fountain, mariculture and attemperation as ground source heat pump in coastal area. It also can lift underground drinking water and mineral water,etc.
Material:
QH series stainless steel submersible pump has several kinds of material.
Seawater and strongly corrosive medium: austenitic stainless steel 316, 316L, tin bronze,etc.
Moderately corrosive medium: austenitic stainless steel 304,etc.
Advantages:
CNC lathe precision machining ensures parallelism and perpendicularity of all the castings.
With rigorous testing, well installation and full load performance test, you can feel easy to use it.
Some of our products manufactured by introducing the Germany Ritz technology, improving the pump’s efficiency and making it more energy-saving & environment-friendly.
Motor parameter:
The motor is accord with GB/T2818-2002 pump industry standard, and it is lubricated by water. The motor must be filled with water. The standard length of the extended cable is 3m.
If you need special requirement, we can extend its length. The working temperature should be a little higher than that of common motor because of its poor magnetic conductivity.
Power:
The general power specification we supply you:380v/50Hz±5. We also can provide customised specifications at your requirements. The variation of voltage and frequency ratings and its influence on motor performance and temperature should meet the requirements of GB755(National Standard)
Notes:
We can provide you the suitable products if the actual working condition, the voltage or the frequency are not consistent with above specifications.
Working condition:
The motor should be submerged into water with the depth no more than 70m;
Solid content (mass ratio): ≤0.01%

- Q: What are the general water pump failure, how to repair?
- Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
- Q: What is the minimum continuous flow of a pump?
- The minimum continuous steady flow can be obtained by test and, in general, the pump supplier will indicate(2) minimum continuous heat limited flow (.API) provides minimum continuous heat limit flow, which means the minimum continuous flow that the pump can maintain and that its operation is not impaired by the temperature rise of the liquid being pumpedMinimum continuous heat limited flow can be calculatedIn the formula, the Pe amount of the fixed axis power is.KW;P pump medium density, kg / m3;
- Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
- High speed rotating impeller blade drives the liquid to rotate, and the liquid is thrown out so as to achieve the purpose of conveying. There are many medium for transportation, such as oil, water, chemicals and so on. The pump shaft and the motor shaft are of the same shaft, the pump and the motor are made into an integral body and immersed in water. The medium of transportation is water.
- Q: How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
- The unit of displacement is the milliliter. How many milliliters does the pump rotate per circle? The displacement is the pump, the individual,The unit of flow is generally a liter, a figure added to the displacement of the pump over a period of time,
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q: The working principle of magnetic pump
- Structure characteristics1. permanent magnetPermanent magnet operating temperature range is made of rare earth permanent magnet wide (-45 - 400 DEG C), high coercivity, magnetic anisotropy direction is very good, also won't happen in the same demagnetization phenomenon when is close, is a good source of the magnetic field.2. isolation sleeveIn the metal isolation, isolation sets in a sinusoidal alternating magnetic field, in a cross section perpendicular to the direction of magnetic field lines induced eddy current and converted into heat. Eddy current expression is:. The Pe - K constant; eddy current; rated speed of N - T - pump; magnetic drive torque; F - the pressure inside the sleeve; D sleeve diameter; a material resistivity; and the tensile strength. When the pump design is completed, N, T is the given conditions, to reduce eddy current only from F, D, and so on. Non metallic materials with high resistivity and high strength production isolation, in reducing the eddy current effect is very obvious.
- Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
- The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.
- Q: Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?
- Submersible pump is best in the water, if dry pumping will cause burns.
- Q: What is the distance between the pump and the wall?
- What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
- Q: How long does the fine stone pump need maintenance? What should I pay attention to?
- Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
