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: Fire pump and shower pump flow head selection, high resolution.
- 3, larger than 25000, the minimum water consumption of indoor fire hydrant is 20L/s4, the minimum water consumption is the flow of a fire hydrant.
- Q: Troubleshooting of diaphragm pump
- The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture
- Q: What's the pump? Where can I use it?
- A pump is a machine that transports liquids or pumps liquids. Pumps are ubiquitous in life. They can be used to transport liquids such as water, oil, acid and alkali, emulsions, suspensions and liquid metals, as well as liquids, gas mixtures, and liquids containing suspended solids.
- Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
- If the fish tank is made of metal, the fish tank is grounded or connected to the zero line, and then the fire line is put into the water, then your fish will be electrocuted immediately. Go back to the submersible pump, submersible pump line and the zero line very close, even if the firing line and the zero line at the same time the leakage occurs, fish could not swim between the firing line and the zero line, so the tank submersible pump leakage will cause the following hazards: 1, electric shock. 2, submersible pump short circuit. 3, the submersible pump serious fever, resulting in water temperature tank.
- Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
- These two don't mean the same thing? That is, the pump outlet can be changed
- Q: Concrete pump 125 pipe wall thickness
- Currently mainly divided into gate valve, concrete pump and S valve concrete pump. Another is a pump consisting of a pump body mounted on an automobile chassis and fitted with retractable or bent cloth poles
- Q: Why does the centrifugal pump start and close first when the outlet valve is closed?
- The contact is burned out, the bond and so on the accident, therefore closes the outlet valve, starts the electric machinery, at this time the electric machinery belongs to the no-load current movement, greatly reduces the big current impact
- 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: Types and differences of pumps
- Depending on the flow of the fluid, they can be subdivided into the following:Classified centrifugal axial flow type mixed flow tubular flow typeThe basic principle of impeller centrifugal force generated by the high-speed rotation of the fluid energy rotary vane extrusion propulsion of the fluid increases the pressure to get the energy mix and energy principle of centrifugal and axial and centrifugalSuch as: central air conditioning centrifugal fan, central air conditioning or cold storage axial flow water pump, mixed flow water pump, domestic air conditioner, indoor fanWorking principle of pump and fanI. the working principle of centrifugal pumps and fansThe centrifugal force generated by the high-speed rotation of the impeller fluid power, namely fluid through the impeller, pressure and kinetic energy can be improved, which can be transported to the height or distance. The impeller is arranged in a spiral shell, when the impeller rotates, the fluid axial inflow, and then turn 90 degrees into the impeller and the radial outflow impeller. Continuous rotation of the impeller inlet in the form of vacuum, so that the fluid continuously by the pump suction and discharge.
- Q: Metering pumps related matters
- 2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.
