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:Water pump does not produce water, what are the reasons?
- The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.
- Q:Common failure treatment of piston pump
- x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
- Q:The water tank of the fish tank does not air out and only has the water outlet
- The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.
- Q:There are second cutting, third cutting, why three times?
- So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.
- Q:What do you mean by the self coupling device on the pump?
- Overview of GAK self coupling device:The utility model relates to a GAK self coupling device, which is an automatic butt joint between a water outlet flange of a submersible electric pump and a water outlet pipe system.In the above additional coupling flange and the water outlet pipe seat inlet flange with a pair of wedge card, under the additional coupling flange and the water outlet pipe seat inlet flange and a pair of wedge cards in a wedge seat below the outlet pipe inlet flange card is made of elastic steel plate is fixed on the lower side of the seat pipe inlet flange. When the submersible pump water falling from above, Kaxianka additional coupling flange at the top of the wedge wedge and seat card outlet pipe above the inlet flange together, in the role of the dignity of the pump and submersible inclined wedge clamp, two flange will be put together in a pair of wedge under additional coupling flange and the water outlet pipe seat inlet flange the card will be in the elastic plate under the action of automatic card together. The utility model can solve the problem that a large amount of water leakage between the two flanges of the coupling is saved when the automatic installation and disassembly of the electric submersible pump is convenient, thereby saving energy.
- Q:Why does the centrifugal pump close the pressure to start?
- The flow is zero (i.e. off dead) minimum, the highest lift power; with the outlet valve opening increases, flow increases, the lift, power and efficiency are increased, the maximum value (usually in the vicinity of the highest rated flow point)
- Q:What are the characteristics of a vertical multistage centrifugal pump?
- Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.
- Q:What is the difference between centrifugal pump and positive displacement pump?
- Positive displacement pump is the volume pump, this type of pump is to rely on changes in volume to compress fluid work, including: diaphragm pumps, gear pumps, screw pumps, etc.;
- Q:Harm of air pump and pump
- Centrifugal pump situationEmpty pump is divided into two kinds, if there is no liquid, then it will cause the mechanical seal of the pump to overheat, wear and even die
- Q:The main factors affecting the performance of centrifugal pumps
- Revolutions required to have. It has the following meanings: 1, similar to the geometry of centrifugal pump, everywhere efficiency at the top of the similar condition; centrifugal pump 2, than the number of different, its geometry must be different than the number; the same pump, its shape is similar, but does not rule out the shape similar situation. The following factors are related to specific speed. The specific speed of centrifugal pump has nothing to do with the nature of the conveying fluid, but has a close relationship with the shape of the impeller and the performance curve of the pump. The pump with high specific speed corresponds to the highest efficiency when the flow rate is large and the head is small
