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: What is the difference between swashplate pump and crankshaft pump?
- Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights the advantage of his adopted lookout!!!
- Q: Fire hydrant pump button, under what circumstances do not need to install?
- The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
- Q: How about the depreciation of vacuum pumps?
- (a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;
- Q: How to select metering pump head?
- In metering fluoride, we recommend the use of Viton, sealed PVC pump head. For most chlorination applications, it is better to use EPDM sealed NP (plexiglass) pump head. For hydrogen peroxide mixtures, only PTFE sealed PTFE pump head or stainless steel pump head can be used
- Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
- The diaphragm pump and centrifugal pump refer to the structure of the pump, and the vacuum pump means the use of the pump. There is no comparability between them.Centrifugal is the sign of inertia of an object. As the umbrella turns, water droplets move out of the outer edge of the umbrella and are thrown out. This is what is called centrifugal. Centrifugal pump is designed according to this principle. The high speed rotating impeller blade drives the medium to rotate and is thrown out so as to achieve the purpose of conveying.
- Q: What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
- Should shut down the valve bar, reduce the flow to increase the point of the head, it is best to adjust within the best range of work, otherwise it is easy to cause the current is too large, burning the motor
- Q: Water pump does not produce water, what are the reasons?
- 4. as a water inlet valve, check whether it is normal, whether the silted up.5. the installation height of water pump exceeds the allowable suction height of pump, or the suction pipe is too long.
- Q: How high can the pneumatic diaphragm pump be?
- If the pump material made of polypropylene (PP) material, corrosion resistance, good chemical resistance using PP material produced by pneumatic diaphragm pump can resist medium low cost, good generality, polypropylene material mainly is especially suitable for general acid-base liquid, using poly propylene made of plastic gas diaphragm pump can only withstand the highest temperature to 65 degrees, more than this number of polypropylene plastic deformation.
- Q: The working principle of magnetic pump
- Structure characteristics1. permanent magnetPermanent magnet operating temperature range is made of rare earth permanent magnet wide (-45 - 400 DEG C), high coercivity, magnetic anisotropy direction is very good, also won't happen in the same demagnetization phenomenon when is close, is a good source of the magnetic field.2. isolation sleeveIn the metal isolation, isolation sets in a sinusoidal alternating magnetic field, in a cross section perpendicular to the direction of magnetic field lines induced eddy current and converted into heat. Eddy current expression is:. The Pe - K constant; eddy current; rated speed of N - T - pump; magnetic drive torque; F - the pressure inside the sleeve; D sleeve diameter; a material resistivity; and the tensile strength. When the pump design is completed, N, T is the given conditions, to reduce eddy current only from F, D, and so on. Non metallic materials with high resistivity and high strength production isolation, in reducing the eddy current effect is very obvious.
- Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you
- When the valve is closed, the flow of the pump is close to zero, the power of the pump is very small, which reduces the load that the motor starts to bear and has a protective effect on the motor. Therefore, the valve closed to start the pump.
