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:What is the difference between centrifugal pump and self suction pump? Which is better?
- In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
- Q:What is the distance between the pump and the wall?
- What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
- Q:What kind of motor does the hydraulic pump need?
- First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)
- 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?)
- Q:What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!
- The vane pump can be divided into centrifugal pump, mixed flow pump and axial flow pump according to the direction of liquid flow in the impeller.Centrifugal pump is a kind of vane pump, which is the most widely used.
- 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:What are the starting and stopping procedures for centrifugal pumps?
- The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
- Q:What are the important parameters of the pump?
- Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.
- Q:What are the basic technical parameters of the pump?
- The basic parameters of the pump, the basic parameters of the main performance parameters of pump are the following: first, water pump flow Q flow is the amount of liquid in the pump unit time delivery out (volume or quality). The volume of flow with Q that the unit is: m3/s, m3/h, l/s and so on. The quality of flow unit is expressed in Qm. T/h, kg/s and so on. The relationship between mass flow and volume flow is Qm= P Q density in P - liquid (kg/m3, t/m3), room temperature water P =1000kg/m3.
- Q:Why should the pump be closed when the centrifugal pump is started?
- Therefore to close the outlet valve, the pump during starting output water, the minimum pump power, when the pump reaches the rated speed, slowly open the outlet valve, gradually increase the flow of water, the motor current is gradually increased to the rated current.
