Product Description:

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;

Water temperature: 20

Solid content (mass ratio): ≤0.01%

Q:Filter backwash pump for what use, what is the principle of work ah?
When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
Q:How do vacuum pumps and pumps work together?
Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".
Q:What's the meaning of the pump head in the water pump, please advise, thank you
According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..
Q:Fire pump and shower pump flow head selection, high resolution.
2, the volume is greater than 10000 is less than 25000, the minimum water consumption of indoor fire hydrant is 15L/s
Q:How is the pump level of submersible sewage pump determined?
Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
Q:What is the difference between centrifugal pump and self suction pump? Which is better?
Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. The centrifugal pump drives the water to rotate through the high speed rotating impeller blade, and the water is thrown out so as to achieve the purpose of pumping water. The impeller rotates at high speed, forcing the liquid at the center of the impeller to be removed at high speeds, resulting in a low pressure at the center of the impeller, and the liquid in the lower trough is continuously sucked.
Q:Which nuclear submarines use the shaftless pump technology?
At present, the submarine has been used in the pump jet technology, the most representative is the United States Virginia class submarine and the Russian North Sea God class submarines.. And shaftless pump is a derivative application of superconducting technology, which is more advanced than pump jet technology..If you want to learn more about shaftless pump technology, you can find relevant papers online.
Q:What is the function of the heating pump system for the water pump design?
Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.
Q:Centrifugal pump flow, why can be adjusted through the outlet valve?
First of all, we know that pump according to the principle of work is divided into speed and volume type, centrifugal pumps are speed type, and reciprocating pumps are volume type.The centrifugal pump can adjust the flow through the outlet valve and outlet valve opening can determine the pump flow and head performance curve parameters such as specific relationship between the outlet flow and pressure can be provided by the data pump manufacturers endplate that even close the outlet valve of the pump pressure will also have a fixed value, but not allow zero flow pump operation, vibration caused by damage to the pump on the mechanical seal is not good and so easy to cavitation, set the minimum reflux line.
