5. FAQ

1       Are your pumps acid-proofed?

To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

2       Can your pumps mount Eff.1 motors

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

3       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.

Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Pump selection to consider the flow, lift, diameter and power, but also with reference to the actual workload, the design quantity is 1666, how much can actually achieve? Head to refer to pipe length, height difference, elbow number, such as flow in more than 800 of the pump, lift at 35 meters, can generally meet about 200 of the pipeline work needs.
Q:2 inches of water pump is generally equipped with high-power motors
Clean water pump 5.5 kw
Q:Water pump motor often inlet
I don't know what the pump is upstairsThe ordinary centrifugal pump inlet outdoor installation, in order to prevent the motor fan end can be installed in the end of 0.5 with the maple leaf canopy, the sheet can be, the supporting leg can be installed in the wind leaf cover screws; if your motor output is water, and the output end of the motor bearing can be installed with the same motor shaft the outer diameter of the rubber water retaining ring (the market for rubber seal should be easy to buy)Submersible pump (pump) often water, you should consider replacing the good points of the mechanical seal, such as to choose oil resistant, acid and alkali resistant, selected according to the transmission medium and the pump itself, if you can confirm the correct, check whether the pump shaft bending, made into concentric mechanical seal damage. And check whether the casting on the motor side is defective or not;Choose a higher level of protection of sewage pump, preferably in the pump leakage probe, float switch, overload, lack of protection, generally will not burn the motor
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
1.5 kilowatts water pump distance 100 meters, with 2.5 square meters of electricity enough
Q:Flow 70 cubic meters per hour; lift 35 meters, choose what standard water pump?
The flow rate is 70 cubic meters per hour. The head is 35 meters, and the SH type double suction centrifugal pump is adopted.Double suction centrifugal pump for conveying liquid water or similar physical and chemical properties of water, according to the needs of users, by changing the pump structure and the material can be used for transport of muddy sand or various corrosive liquids, this series of pumps are suitable for factories, mines, city water supply and drainage, power plants, farmland irrigation and water conservancy.
Q:4--6 inch deep well pump head? How much per hour out of water?.
Best answerLift pump is the location of the outlet is high, such as wells 5 meters deep, you put the pumping pipe on the bottom, the pump is placed in the vicinity of well, then, the head is 5 meters, the water power how much you buy depends on the pump, the greater the power, the faster the water pumping. The greater the party...
Q:Do you need a stop valve for the pump at home?
Must be connected, in the low-end water pipe, the valve is also called the bottom valve is to prevent the intrusion of water, at the same time, but also to ensure the pump again next time when starting the pump and piping in enough water to prevent idling.
Q:Does the water pump pump the coolant into the engine or pump it out?
The automobile water pump pumps the coolant into the engineThe effect of the water pump is used for cooling the engine; it is the coolant pump in the water tank into the engine of the channel, when the engine temperature is about 93-98 of the body's arrival, the thermostat engine open, cooling fluid from the thermostat back into the tank....
Q:After the pump has a control box, but also the distribution box?
1, after the pump has the control box, do not need the distribution box.2. The control box is not the same as the distribution box.Wiring principle is as follows: from the distribution box power supply into the control box, L1, L2, L3 (usually so); from the control box to connect U, V, W to the water pump.
Q:Pump impeller diameter plus assembly what changes? What's the effect on the motor?
Two item 1.5 kilowatt type self suction pump original impeller 14.7cm installed 15.5cm may be a problem.After the impeller increases, the flow, head, shaft power will increase (increase in volume see the following formula), the original 1.5KW motor may overload operation.The larger the diameter of the impeller, the greater the lift, the greater the flow rate, because the flow rate of water depends on the centrifugal force generated by the impeller rotation and the line speed on the tangent. The greater the diameter, the greater the centrifugal force and the linear speed. The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment. Vacuum pumping or vacuum pumping two times.The vacuum of the inlet of the centrifugal pump is composed of three parts (the equation of the inlet of the pump and the level of the suction liquid).
