FAQ

Q: Are your pumps protected against dry running?

A: 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: How can I get trained on CNBM products?

A: 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: Are your pumps cheaper than those of your competitors?

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

Q: Do you have self-priming pumps?

A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

Q: Is it really necessary to fit a bleed valve for the boxes?

A: It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q: If I increase the power of the motor, must I also increase the power of the inverter?

A: You must select the size of converter that allows maximum absorption of the electric motor.

Q:Why does the water pump leak?
The leakage of water pump is caused by many factors:1, the axial movement of the bearings (axial clearance is too large, resulting in static and dynamic ring open. Leak water.2, and automotive cooling liquid is also related to, if the pH of the coolant is large, will corrode the water seal of the surface, resulting in leakage.3, and the user's use is also related, and some users do not properly maintain, add an unclean coolant, resulting in impurities in the coolant. Accumulation in the water seal surface, destroy the water seal torus, forming water leakage.
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:How to remotely control submersible pumps?
Now the remote control of submersible pumps and pumps is very mature, and the cost is relatively low. We use the Ji'nan Huichi electronic pump remote controller controlled step-down start control cabinet, convenient Clockwork SMS can control the pump start and stop, and return to the working condition of the water pump, water pump overload or lack of power can also feedback fault message to the responsible person
Q:Should the no-load power of the pump be equal to the rated power?
We must first clear the meaning of rated power; rated power is called the reference numerical electrical power consumption in the voltage conditions specified, and the actual power consumption of electrical appliances is different in different situations, the pure resistance (such as lighting, electric) as long as the voltage conditions, the actual consumption of electric power close to or equal to the rated power, and for appliances like motor, electric power consumption, not only related with the voltage, but also with the relevant load. For example, someone with 200 pounds of energy, then the person in the condition of small meal, maximum load of 200 pounds, but if you take as long as he is 100 pounds, of course he relaxed, he would not say must bear 200 pounds!You measure the pump power is less than 1200W, first you did not mention your use of voltage is not rated voltage, then you don't want him full load, the suction is far less than 8 meters, there is no mention of whether you send water to 50 meters (Yang Cheng), there may be insufficient voltage, and you have don't need it so much power consumption. Of course, one advantage is that it doesn't burn easily. It is easy to burn if it is used at full load.
Q:What is the 10KV pump unit?
As the name suggests, the water pump unit is a number of pumps, and 10kV is the voltage level. According to the voltage level, what you call a water pump should be a pump with relatively large power
Q:How to determine the pump installation elevation, why should we determine the pump installation elevation?
Water pump installation elevation should be in accordance with the water pump suction head, taking into account the water level of water intake and fall. The minimum water level at the water intake point must be less than the suction head of the water pump, otherwise the water intake will not be enough.
Q:Water pump mutual switching device
The main purpose of the control is to make sure that the pump outlet has a nominal pressure.Control requirement: 1. Start single pump manually.2, two pumps should alternate.3, the pump exports to achieve certain pressure, the normal operation of the motor, and the pressure is too low, the operation is meaningless.Device: AC contactor, intermediate relay, etc..Principle: 1, detect a pump fault (usually take the motor main contactor, auxiliary contact), interlock another pump to start.2, pump outlet pressure detection device detects low pressure, can start another pump at the same time, to ensure the normal export pressure!
Q:Pump head is too high what's the impact?
Measure the height of 50m, using 100m lift pump, the disadvantage is a waste of energy, such as the selection of 100m lift pump, flow of 10 cubic meters, motor power 5KW, with less than 5 0m lift pump, flow of 10 cubic meters, motor power 5KW, so that the lift ratio measurement height is greater than 10-20%, on the same pump motor power next, the pump head is larger, less water.If the height of 50m is measured, the pump with 100m lift head is used, but what is the influence of the flow rate on the pump or pipe?.
Q:(flood control emergency plan) what type of water pump should be used for flood control? How to choose
Select the QW submersible pump, which is potential water, (flow, lift, bore, power)Flow, how many tons of water pump an hour to play, you choose how much?Lift, water pump from the destination is a few meters, how many meters?,Caliber, this pump potential water, without flange connection, only flow, head can reach.Power, look at the flow and lift is how much, and then choose the right motor (this is regular)The voltage is usually 380V.You can move, it is best to fix a seat, weight, this pump is basically a person can not move, and small can take.Brand, regular manufacturers can.Model, (caliber, flow, lift, power, voltage) tell the manufacturer.
Q:Why is the water pump usually used multi-stage pumps, while the circulating pump is usually a single-stage pump?
Mainly determined by the function of the water supply pump and the circulation pump.Replenishment pump is mainly to supplement the loss of the system, so the general flow is smaller, larger head, single pump water model in a small flow situation, many are not up to the required head, can only use multi-stage pumps.Circulating pumps are generally large flow, low lift, heavy efficiency, economic operation, and hydraulic model point of view, are single-stage pumps more appropriate, especially single stage double suction pump.
