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 a vacuum pump for?
In fact, the vacuum pump and high Swiss fan, high Swiss high-pressure blower, high Rui high-pressure pump principle is almost the same
Q:What is the "variable" of a variable pump?
There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).
Q:Attention should be paid to the use of pumps?
To carefully check whether there is a crack impeller, impeller fixed in the bearings are loose, if there are cracks and loose, hungry phenomenon should be promptly repaired, if the pump impeller above the soil should also be cleaned
Q:Fire pump and shower pump flow head selection, high resolution.
Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s
Q:Common failure treatment of piston pump
1) overflow valve regulation is too high, overload after the pump2) the overflow valve spool is blocked, the central hole of the valve core is blocked or the overflow valve is blocked by a damping hole, and the overflow is not overflow3) pump outlet one-way valve installed or spool blocked and stuffy pump4) motor fault x091) adjust the relief valve pressure value2) repair valve boring3) overhaul check valve4) overhaul or replace the motor
Q:How many concrete pump tube diameter
The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone
Q:Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
Four) release bolus dosage method can use automatic release and manual release two ways, the key is to alarm after the infusion must be stopped(five) any kind of pill dose release are not restricted to replace the pill. The total dose limit for in pipe blockage after pill agglomeration process will remove blocking accident, this time will be the rapid infusion of pill dose concentration into the patient's blood, if the total dose pill does not get test and limit, rapid infusion of this accident it may have unimaginable consequences.(six) supplies open type infusion pump overflow on the domestic market for pill characteristic parameters of consumables simply without testing and limitation. Therefore, the risk of accidental pill has become one of the residual risk of open type infusion pump supplies the most deadly.
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:How to calculate the motor power of metering pump?
The motor power of the metering pump is divided into two parts1. mechanical power, this part of the power metering pump design part will be some data, mainly to control the mechanical structure of the metering pump required power
Q:Why can't the centrifugal pump pump the vacuum?
Condition:The pump shell must be filled with liquid under certain installation height and running without leakage.What is the phenomenon of centrifugal pump? What harm does it have? How to eliminate?)
