Q: The function of centrifugal pump: 4, bearings are set on the pump shaft supporting the pump shaft components, there are two kinds of rolling bearings and sliding bearings. Rolling bearings use butter as a lubricant, refueling should be appropriate, generally 2/3 ~ 3/4 of the volume is too much, will heat, too little, there is noise and fever! The plain bearings are made of transparent oil as a lubricant and fill up to the oil level. Too much oil will leak out along the pump shaft and float *, too little, the bearings will overheat and burn out, causing accidents! In the pump running process, bearing temperature is highest in 85 degrees, generally run at about 60 degrees, if higher, will find the reason (whether there is impurities, whether the oil is black, whether water) and timely processing!

Q: Is the diaphragm pump and the drain pump one?: First of all, there's something wrong with your concept.Diaphragm pump is in accordance with the way the pump classification, drain pump is in accordance with the use of pumps classification.

Q: What is double hydraulic pump?: Two hydraulic pumps installed on one shaft can be connected to increase output flow, and can also be connected to increase output pressure. See how the demand is. The system can change the mode of application at any time.

Q: How many kinds of pumps are available and the operating principles of various pumps?: There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..

Q: What are the application areas of pumps?: 1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system

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 is the main difference between SK water ring vacuum pump and 2BV water ring vacuum pump?: SK vacuum pump is a single-stage water ring vacuum pump, vacuum pump and motor separation, coupled with couplings, vacuum relatively low.

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?: First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.

Q: Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?: Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa

Q: Why can't the centrifugal pump pump the vacuum?: Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.
