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 is the difference between swashplate pump and crankshaft pump?
- In hydraulic system:Axial piston pump is the use of parallel with the transmission shaft in the plunger plunger reciprocating movement of the volume changes generated by the work. As the plunger and the plunger hole are circular parts, processing can achieve high accuracy with the high volume efficiency, stable operation, good flow uniformity, low noise, high working pressure, but the hydraulic oil pollution is more sensitive, more complicated structure, high cost.
- Q: What are the causes of pump shock?
- Troubleshooting cause1. bearing damage, replace new bearings2., coupling pin, bolt damage, rubber column or metal bolt wear, change
- Q: What should I pay attention to when buying a pump?
- There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.
- Q: What is the pump, how to classify, mainly used in where?
- Classification of pumpsAccording to the principle of division:1. displacement pumpDepending on the movement of the work parts, the volume of the work increases periodically and reduces the suction and discharge of the liquid, and the pressure of the liquid increases directly by the extrusion of the working partsAccording to the different movement of moving parts, it can be divided into two types: reciprocating pump and rotary pumpAccording to the structure of the moving parts are different: piston pump and piston pump; there are gear pumps, screw pumps, vane pumps and water ring pump
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.
- Q: Concrete pump 125 pipe wall thickness
- Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.
- Q: What is the difference between centrifugal pump and positive displacement pump?
- The centrifugal pump is to rely on high-speed rotation of the impeller to do work on the fluid. These two types of pumps are also the most widely used.
- Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
- (three) infusion limited number of pills produced after the dose of obstruction by infusion pump and specification of the matching test, will reach acceptable when the storage pressure of the pressure to determine the alarm blocking. Thus, some have restrictions on the infusion tube blocked after the maximum dose pill may have blocked the trigger before the alarm.
- Q: How high can the pneumatic diaphragm pump be?
- Diaphragm capacity, high temperature, pneumatic diaphragm pump ability, high temperatureMany users do not know how high the temperature resistant diaphragm pump, diaphragm pump either electric diaphragm pump or pneumatic diaphragm pump products it cannot do without diaphragm attachments, diaphragm materials mainly fluorine rubber, rubber, rubber, polyether road three EPDM, PTFE several, if not considering the gas temperature resistant diaphragm made of stainless steel. The temperature to 600 degrees of diaphragm pump diaphragm pump, but must use the diaphragm, so the diaphragm pump can Naiduo high temperature depends entirely on the diaphragm was affected by temperature, following to share various diaphragm pump diaphragm material and different material temperature choice diaphragm pump product right:
- Q: What is the distance between the pump and the wall?
- What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
