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: Fire hydrant pump button, under what circumstances do not need to install?
- General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
- Q: Troubleshooting of diaphragm pump
- The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
- Q: What should I pay attention to when buying a pump?
- There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.
- Q: How to install, operate and maintain the pipeline booster pump?
- When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.
- Q: What does electromechanical vector pump mean?
- Scope of application is;Residents living water: such as high-rise buildings, residential areas, villas and so onPublic places such as hospitals, schools, gymnasiums, golf courses, airports, etc
- Q: What is the function of the heating pump system for the water pump design?
- As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
- Q: Why does the centrifugal pump start and close first when the outlet valve is closed?
- The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
- Q: Why is the sewage pump device coupler?
- Automatic coupling installation of sewage pump is a sewage pump with automatic coupler and a guide rod guide chain fixed installation, convenient maintenance, manual maintenance can be directly hung up by the pump coupling device, ordinary sewage pump is generally Mobile
- Q: How accurate is the metering pump?
- The measuring accuracy of the stable metering pump is as follows:In a diaphragm metering pump, the reciprocating motion of the plunger is passed to the diaphragm through the hydraulic chamber between the plunger and the diaphragm. In order to maintain the normal movement of the diaphragm, the hydraulic chamber is required to keep the volume of the liquid in the space (usually using hydraulic oil) unchanged. In order to ensure that the volume of the formation of membrane movement is always equal to the stroke volume of the plunger pump, so as to maintain the stability of the flow, but in the actual operation of the pump, the plunger seal will inevitably cause leakage at the same time, there may be a gas into the hydraulic chamber
- Q: Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines? Why?
- Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
