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:Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
(1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump
Q:What is a solution pump?
Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
Q:What are the reasons for sealing damage of centrifugal pumps?
The reasons for sealing damage of centrifugal pumps are as follows: six, the specific contents and handling methods are as follows:First, the centrifugal pump water quality is poor, containing particles.As a result of poor water quality, containing small particles and medium hydrochloride content is high, forming abrasive wear, centrifugal pump seal plane or pull the surface, resulting in groove, ring groove and so on.Treatment method: improve water pressure or medium, replace machine seal.
Q:What is the difference between centrifugal pump and rotary vane pump?
This is a classification problem.Rotary is classified by movement, vane pumps are rotary, volumetric pumps are mostly rotary, piston pumps, etc., is reciprocating.
Q:Advantages and disadvantages of centrifugal pumps?
The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.
Q:How to calculate the motor power of metering pump?
The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
Q:What are the starting and stopping procedures for centrifugal pumps?
Operation method and operation procedure of self-priming centrifugal pumpClick number: 440 release time: 2011-7-24Centrifugal pump method, centrifugal pump operation steps, centrifugal pump use steps
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The choice of pressure depends on the size of the load and the type of equipment. Consideration shall also be given to the assembly space, the economic conditions and the availability of components for the actuators.In the case of a certain load, low working pressure, is bound to increase the structure size of the actuator on some devices, the size must be limited, from the perspective of material consumption is not the economy; on the other hand, the pressure to choose too large, the pump, cylinder, valve and other components of the material, sealing and manufacturing accuracy requirements very high, must raise the cost of equipment.
Q:The distance from the pump button to the ground
Yellow warning pop-up, indicating that the fire control room has issued alarm information, fire alarm controller (commonly known as the alarm host)
Q:Know flow and lift how to calculate the pump power?
The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
