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: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:What is the series of pumps? What's the difference between a unipolar and a multistage?
You're talking about a centrifugal pump. His series says the number of slices of the impeller (excluding the wheel, that is, the wheel)
Q:Any center of the pump
Looking forAlignment means the position of the center of rotation of the pump and motor so that they are in the same line.At least three times after the initial installation or after installation:
Q:Hydraulic pump displacement refers to the pump shaft what?
Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),
Q:Must the water pump in the tank be all soaked in water?
Of course, if the motor is overheated, it will burn, and the temperature of the water will drop down.
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
A standard atmospheric pressure can be 10.33 meters to 30 meters of water, suction is atmospheric pressure there are three standard atmospheric pressure so high? This is impossible in general, remove the vaporization removed 0.5 meters critical yo,
Q:Concrete pump 125 pipe wall thickness
Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.
Q:Troubleshooting of diaphragm pump
In the application of the pump, these conditions are likely to encounter. Each situation can be divided into several possible reasons. This guide lists the causes of failures and gives appropriate corrective maintenance measures. The meaning of all the specific terms in the guide is listed later.Air valves - copper or stainless steel valves are bolted to the center of the pump by four bolts.The piston aluminum cylinder is enclosed in the air valve to control the gas flow.Cavitation - because the pump inlet for the amount of fluid to reduce or lack, the pump discharge is less than the amount of quantitative. In fact, the fluid chamber is full of fluid before it is discharged.Static pressure drop - the inlet pressure from the pump centerline to the free point - the inlet is measured in pounds, including the specific gravity and velocity of the fluid.
Q:Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.
If the water pressure is not enough, the pump can not start, then it must be wrong. Because if the water pressure is not enough, the pump should be running automatically. It's just because the water pressure is not enough.
Q:What is a gear pump for?
Oil pump casing wearIt is mainly the wear of the floating sleeve hole (the normal clearance between the gear shaft and shaft sleeve is 0.09~0.175mm, and the maximum shall not exceed 0.20mm). The gear work is affected by the pressure oil, the gear tip is close to the oil pump casing, and the low pressure chamber part of the pump body is worn. Another kind of wear is the circumferential wear of the work surface in the shell. This kind of wear is mainly caused by the addition of oil which is not clear, so the oil without impurities is necessary.
