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: Why does the centrifugal pump close the pressure to start?
- The flow is zero (i.e. off dead) minimum, the highest lift power; with the outlet valve opening increases, flow increases, the lift, power and efficiency are increased, the maximum value (usually in the vicinity of the highest rated flow point)
- Q: What are the reasons for sealing damage of centrifugal pumps?
- Three, water shortages caused by running dry grinding damage.This phenomenon is more common in mounted form inlet pressure, inlet air, air cavity pump, pump boot, high temperature operation of the mechanical seal friction at high speed, can not be cooled, check the mechanical seal, the spring tension is normal, the friction surface of charred black, rubber hard cracking.Treatment methods: exhaust the pipe and pump cavity air, replace the machine seal.Four, install too tight, observe the mechanical seal of dynamic and static ring plane, if there is serious burning phenomenon, flat black and deep traces, sealing rubber hardens, lose elasticity.This phenomenon is due to tight installation.Treatment methods: adjust the installation height, impeller installed, with a screwdriver to move the spring, the spring has a strong tension, release after the reset, there is 2-4mm moving distance can.
- Q: Advantages and disadvantages of centrifugal pumps?
- The centrifugal pump has no valve, so it is suitable for conveying suspended liquid, and the special design can also transport large solid suspensionThe pump can be made of chemical resistant material, which is suitable for conveying corrosive solution.The utility model has the advantages of simple structure, few parts, little failures, durability, low maintenance cost, convenient management and reliable work.The output can be adjusted even by the discharge valve fully closed, there is no danger of infinite rising pressure head.The liquid is transferred to a large quantity. And the pressure head does not require large, most suitable for centrifugal pump.
- Q: Why should I pump the pump before starting the centrifugal pump?
- 1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)
- Q: What's the difference between non negative pressure and variable frequency water pump?
- When peak water is used, the fluctuation of water pressure will be the same for customers! Because the key to the fluctuation of hydraulic pressure is the flow rate of the pump and the lift of the pump. As long as the flow of the selected pump is large enough, the tank is large enough, the lift head is suitable, and the pressure fluctuation is relatively small. And the selection of non negative pressure and frequency conversion pump group is not directly related. If the municipal tap water pressure and water sufficient (large enough diameter), the use of non negative pressure is better. If the municipal tap water pressure and water shortage, you can only use the frequency converter pump + water tank, no negative pressure can not be used.
- Q: What is the difference between centrifugal pump and positive displacement pump?
- Positive displacement pump is the volume pump, this type of pump is to rely on changes in volume to compress fluid work, including: diaphragm pumps, gear pumps, screw pumps, etc.;
- Q: Is the sewage pump the same as the mud pump?
- The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.
- Q: How high can the pneumatic diaphragm pump be?
- Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.
- Q: Is the centrifugal pump large or small?
- NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.
- Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
- Pigment pressure is less than 0.4mpa,About 0.3. Go up.As the pump diaphragm is in the middle of a connecting rod, equivalent to the cylinder cavity, the pressure will be reduced; and because of the loss of pigment tube pressure will be reduced.
