1. Product overview
QJ series deep well submersible waterpumps are widely used in farm irrigation, sprinkler irrigation, getting water from well, water supply and drainage system for industrial and civil building, water diversion project in hilly and mountain areas water drainage project in at low-lying areas, water supply and drainage in urban and rural's mining enterprisesand various ther kinds of water conservancy facilities. Its features are that the Motor and pump are assembled into a whole, so that it is simple in structure, convenient to assemble and disassemble, easy to use and maintain safe to operate. Otherwise, it covers an small area and does not pollute water.

5. FAQ
(1) Can your pumps mount Eff.1 motors
Currently, only on request though this will shortly be a CNBM standard.
(2) Are your pumps protected against dry running?
No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.
(3)How can I get trained on CNBM products?
Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.
- 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.
- Q: What are the internal losses in centrifugal pumps? How did they come about?
- Hydraulic loss: the loss of water by friction, eddy, impact, etc in a flow;
- Q: The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
- 1. submersible pumpsA very wide range of water treatment tools. Unlike ordinary water pumps, it works underwater, while the pump works mostly on the ground.The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.Basic parameters of submersible pumpIncluding flow, lift, pump speed, matching power, rated current, efficiency, diameter and so onSubmersible pump main application and scope of applicationIncluding construction, construction, drainage, agricultural irrigation and drainage, industrial water recycling, urban and rural residents cited water supply, and even rescue, disaster relief and so on
- Q: Why can the centrifugal pump hold down the pressure?
- Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.
- Q: Water pump does not produce water, what are the reasons?
- 1 check whether the motor is reversed.2, to see whether the export, the entrance blocked, the outlet pressure gauge whether there is pressure.3, whether the pump selection is wrong, you can not suck up the water.
- 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!
- Directly said vane pump on the line, generally do not say rotary vane pump.The centrifugal pump is divided according to the direction of the liquid flow in the impeller
- Q: Is the sewage pump the same as the mud pump?
- The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.
- Q: Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
- By adjusting the amount of oil entering into the hydraulic coupler, the torque of the hydraulic coupler can be controlled
- Q: Harm of air pump and pump
- If the liquid is not full, this situation is generally the suction pipe or pump shell leakage, then easy to cause cavitationHit the pump for centrifugal pumps, centrifugal pump is recommended to start closed, the discharge valve closed, starting is in the state of pump
- Q: What are the failures and causes of the replacement of the fuel pump assembly?
- Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.
