Q: Fire hydrant pump button, under what circumstances do not need to install?: There are four things to do:Fire hydrant button to meet the requirements of national standards.In addition to pumping, it can show the location of fire.

Q: What are the internal losses in centrifugal pumps? How did they come about?: Due to the friction of the bearing, the friction in the stuffing box, and the losses caused by the rotation of the impeller (the loss of the roulette wheel);

Q: The function of centrifugal pump: 2, pump body, also known as pump shell, it is the main body of the pump. The utility model is provided with a supporting and fixing function and is connected with a bracket for mounting the bearing.3, the role of the pump shaft is to use the coupling and motor connected, the motor transfer distance to the impeller, so it is the transfer of mechanical energy of the main components.

Q: What is the pump lift voltage? And how to suppress the pumping voltage rise?: [suppression of pumping voltage] the general use of the installation of absorption resistance to absorb the pump voltage rise. The simplest way to control the pump voltage is to connect the DC bus with an energy consumption resistor before releasing the pump voltage.

Q: What is the name of the day pump and ground pump? Specific introduction: PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.

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: Operating procedures for measuring pumps: Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload

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: What are the parts of a pump? How do you classify it?I just want to know: The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,

Q: What are the failures and causes of the replacement of the fuel pump assembly?: Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.
