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:The function of centrifugal pump
- 4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!
- 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:Why can't the centrifugal pump pump the vacuum?
- Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
- Q:What is an industrial water pump?
- Classification by usagePump, circulating pump, fire pump, pressure test pump, sewage pump, metering pump, sanitary pump, dosing pump, pump, pump, gelatinization defoaming pump, flow pump, oil pump, water pump, drainage pump, drainage pump, dredging pump, sprinkler pump, booster pump, high pressure pump, heat pump high temperature, low temperature, pump pump, condensate pump, heat pump, cooling pump, heating pump, deep well pump, analgesic pump, pump, pump, chemotherapy, blood pump material pumping pump, pump, pump, sulfur removal, shearing grinding pump fuel pump, pump, pump, quillback bath source heat pump, filter pump oxygen pump, pump, shampoo, injection pump, air pump, gas pump, pump, pump, art odorization pump chopped
- Q:How is the pump level of submersible sewage pump determined?
- Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
- Q:What are the internal losses in centrifugal pumps? How did they come about?
- Due to the friction of the bearing, the friction in the stuffing box, and the losses caused by the rotation of the impeller (the loss of the roulette wheel);
- Q:What is a feed pump?
- In general, high lift pumps are required with a front pump (which is similar to the feed pump of the landlord) or a low position;
- Q:Is the flow meter in front of the pump or after the pump?
- Agree upstairs. Pump should be straight before the paragraph, 15 times the nominal length of the caliber.
- Q:Filter backwash pump for what use, what is the principle of work ah?
- But the reverse cleaning can not completely regenerate the filter medium, or there will be some impurities remain, when the regeneration of residual impurities (pressure drop) to set the value, you need to replace the filter (filter media).
- Q:Water pump can not be pumped out, how to maintain water?
- Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.
