5. FAQ

(1).  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.

(2).  Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

(3).  How long is your warranty?

Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications. Either the delivery documentation or the invoice must be provided to prove delivery date. In absence of such documents, the production date appearing on the product label may suffice.

(4) Can your pumps mount Eff.1 motors

Currently, only on request though this will shortly be a CNBM standard.

(5) 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.

(6)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:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Have to know the ratio, pneumatic pump, if high pressure, you can have 2:1,3:1
Q:What is the pump delivery? What's the difference between years and years?
First of all, as a student majoring in insurance, I strongly condemn the first floor of ignoring practice and trampling on real knowledge!!The insurance industry criticized a lot, but it is required for many people, we should face and try to maintain the healthy development of the industry, the first floor of the insurance you have not done, have no contact with the insurance, insurance, not to dictate the nonsense, more should not be here misleading!
Q:What is the nominal pressure of the hydraulic pump and hydraulic motor?
Rated flow refers to the flow under the rated speed and rated pressure input to the motor.Due to leakage loss, the actual flow of the input motor must be greater than its theoretical flow. Actual flow of motor (i.e. inlet flow) leakage flow = theoretical flow of the motor.
Q:What are the starting and stopping procedures for centrifugal pumps?
Before using the centrifugal pump, the operation instructions of the centrifugal pump shall be read carefully and the specific operation procedures shall be understood so as to make proper use of the centrifugal pump products. The first step is the operation of centrifugal pump inlet valve of centrifugal pump centrifugal pump for all open cavity filled with liquid, close the outlet valve, start the motor, the motor speed is normal, can gradually open the outlet valve, to adjust to the desired condition. Pay attention to self suction centrifugal pump starts to open the exhaust valve, outlet valve should be opened quickly in the normal operation of the motor, to prevent air inlet pipe off caused by cavitation phenomenon produces centrifugal pump, centrifugal pump vibration phenomenon leads to noise of the smoke is not on the water.
Q:Why is the submersible pump tripped on an electrical switch?
There should be the following reasons: 1) the setting value of the trip switch is too small, and the operating current of the submersible pump exceeds its setting value, and the switch is tripped
Q:Water pump dead center lift
The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
Q:What is a gear pump for?
Internal wear of oil pumpOil pump parts wear will cause leakage. The large leakage area between the floating axle sleeve and the end face of the gear is the main part of the inner leakage. This part of the leakage accounted for about 50%~70% of the total leakage. The pump efficiency of the gear pump is much lower than the input power when the gear pump is worn and leaked. All of its losses are converted to heat energy, which will lead to overheating of the oil pump. If the joint plane is pressed, the movement of the floating axle sleeve will cause a little wear and tear when the work is in use, so that the farm tools can be lifted slowly or can not be improved, so the floating axle sleeves must be replaced or repaired.
Q:Harm of air pump and pump
Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead
Q:Is vane pump good or gear pump good?
The main working parts of vane pump is provided with a plurality of sliding vane rotor, when the rotor rotates, the eccentric configuration of stator cavity contour or rotor, blade sliding slot in leaves due to volume changes, resulting in the suction effect. The similarities are: 1, rotary type positive displacement pump has self-priming ability, but are not allowed to do; 2, with continuous flow pulsation, but also have flow and pressure; 3, the theory of flow is determined by the working parts of the size and speed, has nothing to do with discharge pressure; 4, rated discharge size, pressure and working parts mainly depends on the pump speed is independent of the sealing parts and bearing capacity; differences: 1) gear pump structure is more simple, reliable, low price; vane pump has complicated structure and high manufacturing precision parts, the blade is easy to get stuck, more sensitive to the oil clean degree and viscosity.
Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?
First, what is cavitation?:When the centrifugal pump shell has air, it produces less centrifugal force because the density of the air is much smaller than the density of the liquid. Thus, suction pressure at the entrance to the top of the tank liquid level and pump is bad enough to the liquid storage tank into the pump, the centrifugal pump self suction capability, the centrifugal pump can not transport liquid, this phenomenon is called "cavitation".When a liquid drops at a certain temperature to the vapor pressure at that temperature, the liquid produces a bubble. The phenomenon of producing bubbles is called cavitation. When the cavitation bubbles, flow to the high pressure, the volume of reduced, so as to burst. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse.
