4. FAQ
1) Are CNBM pumps available in DIY stores?
Yes, currently, we’re available for DIY stores all over the world.
2) Where do I have to send pumps for service?
You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.
3) 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.
- Q: What are the characteristics of a pipe shield pump?
- Two, reverse circulation type of shielding pump, its bearings, lubrication, cooling and motor cooling fluid flow direction and the basic type is the opposite. The main characteristic of reverse circulation pump is that it is not easy to generate cavitation. It is suitable for conveying liquid which is easy to vaporize. Sometimes it is also called "easy to vaporize" type. Three, high temperature medium temperature of up to 450 degrees. The cooling water jacket is usually added outside the shielding motor, and a cooling sleeve is added to the outer circulation pipe to cool the high temperature circulating liquid to reduce the temperature of the motor and the bearing. In the case of less power, some manufacturers do not use cooling liquid, but the outside of the motor is equipped with fins and the special winding to adapt to the working conditions, the use of temperature generally can not exceed 400 degrees.
- Q: How to select metering pump head?
- The main index affecting the selection of the pump head is the composition of the medium to be transported and added, as well as the pressure and the temperature of the external environment
- Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps
- The diaphragm works by changing the size of the diaphragm. When the cup is covered with an eraser and the edge is airtight, then pressing the rubber or pulling the rubber outward will make the pressure in the cup increase or decrease. Use this principle, in the pressure of an hour from a hole suction medium, when the pressure is large, from another hole extrusion medium, so as to achieve the purpose of conveying.
- Q: There are second cutting, third cutting, why three times?
- So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.
- Q: Why should I pump the pump before starting the centrifugal pump?
- Only centrifugal water can be pumped out of the centrifugal blade to generate negative energy at the entrance. There is no water diversion. Only the negative pressure produced by the air is too low to absorb the well water.Water pump has been pumped, centrifugal pump or can not start normally, mostly because of the water pipes and air
- Q: Harm of air pump and pump
- If the liquid is not full, this situation is generally the suction pipe or pump shell leakage, then easy to cause cavitationHit the pump for centrifugal pumps, centrifugal pump is recommended to start closed, the discharge valve closed, starting is in the state of pump
- Q: If the calculation of the required pump flow is 45, lift 110, and the actual pump flow 100, head 125, what will happen in operation? Can I use it properly?
- Centrifugal pumps are too big to measure.There is a reason why the centrifugal pump does not measure up:The pump inlet pipe blockage, leakage.The pump inlet pressure is too low.
- Q: What are the main performance parameters of the pump?
- RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power
- Q: Which nuclear submarines use the shaftless pump technology?
- Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
- Q: When the water pump is started, why should it start when the outlet valve is closed? Thank you
- And the pump at the start, if the valve opening pump, then the pump outlet pressure (head) is very small, so the pump flow will be great, the pump power is very large, causing the start-up current is very large. In addition, the starting current of the motor itself is also very large. These two factors add up to the possibility of overloading the motor, resulting in failure to start or even burn the motor.
