Q: Are your pumps acid-proofed?

A: 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.

Q: Can your pumps mount Eff.1 motors

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

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:Two pumps automatically switch start control circuit,
Can add time delay relay, the key depends on how much time the water is full, if you design is automatic, it is better to use the triode reliable,
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).
Q:2 inches of water pump is generally equipped with high-power motors
Clean water pump 5.5 kw
Q:Water pumps are always pumping water, what's the matter?
Cause analysis of water pump without waterThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.(2) in contact with the water pump inlet of the horizontal application of reverse flow direction, fell more than 0.5% slope, connect one end of the highest import pumps, do not completely level. If the upward tilt, the intake pipe will retain air, reducing the water pipes and pumps in the vacuum, water absorption.(3) pump packing has been used for long-term wear or packing pressed too loose, discharge gap caused by the large amounts of water from filling with the shaft sleeve, the external air gap into the pump from the inside, affected the water.(4) because of the long latent water and the corrosion of the pipe wall, the water inlet of the water inlet is constantly dropping. When the holes appear above the water, the air enters the water inlet pipe from the hole.(5) there is a crack at the bend of the inlet pipe, and there is a small gap between the inlet pipe and the water pump, which may cause the air to enter the inlet pipe.
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed water pump is the water pump for the entire boiler, and the water needed by the boiler is supplied by a feed pumpThe condensate pump is supplied to the deaerator after condensing the condensate from the turbineVacuum pump water jet pump should be said, to ensure the turbine vacuum pumpThe low drain pump is the power pump of the low temperature heater
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
When you buy the pump, you can ask the manufacturer to give you an FM curve so that you can see the change in the efficiency of the pump as the frequency is adjustedSend you a document in the hope that I can help you
Q:1.5 kW three-phase pump with 600 meters line, should match what big line?
Do you want to see the line loss how much pressure drop, if you want to ensure the working voltage of certain you pump, 600m pressure drop should be two-way, namely power press 1200m, press 380V, 1.5KW working current is calculated according to 3A R=, according to the resistivity * length / cross-sectional area of =0.0175*1200/S=21/S, and the loss of pressure drop =R*I=21*3/S=63/S, S take 3, loss of pressure drop is about 20V, the comprehensive economic cost, take 3 more appropriate, if you are willing to take 5, 6 are never mind, the thicker the loss is smaller.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:QDX is a submersible pump. What does "X" mean?
QDX is a submersible pump model, its specific meaning is:1.Q: submersible pump.2.D: single-phase power supply, three-phase electricity is not marked.3.X: pump, pump type is not marked.Complete submersible pump model will generally add rated flow, rated lift and motor power rating. For example: QDX40-8-1.5, meaning with single-phase 1.5KW motor, rated flow of 40 cubic meters / time, the rated lift of 8 meters under the pump submersible pump.According to the different relative position of pump and motor, submersible pump is divided into pump type and pump type. The pump submersible pump motor in the above, below, this structure greatly reduces the radial size of the pump, so much for submersible pump and small submersible pump operation. Submersible pump submersible pump on top of the pump in the following, it is divided into two types of internal and external type. The submersible pump carries the liquid through the annular flow passage around the motor, then cools the motor and then flows out of the pump outlet. Even though the pump is near the drain sump, there is no need to worry about the temperature rise of the motor, so the application is becoming wider and wider. External pump submersible pump directly from the pressurized water chamber after the impeller or diffuser outlet of discharged liquid, motor is cooled by liquid pumping. As the lower pump structure can work in a relatively shallow liquid, it is often used in submersible pumps for operating surfaces, especially the main structure of large caliber submersible pumps.
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.
