- Q: Why does the centrifugal pump close the pressure to start?
- The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.
- Q: What is a water pump coupling device?
- The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
- Q: Fire hydrant pump button, under what circumstances do not need to install?
- The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
- Q: What is a solution pump?
- Principle and structure features of canned motor pumpThe ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and drive the rotor. This structure eliminated the traditional centrifugal pump with a rotary shaft sealing device, it can do no leakage.The pump and motor pump together, motor rotor and pump impeller fixed on the same shaft, use of shielding the rotor and the stator of the motor rotor separated in the medium, its power is transferred to the rotor through the stator magnetic field.
- 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: Brief description of centrifugal pump on / off operation
- First, the preparation before the start(1) carefully check the inlet and outlet pipe line, valve, flange and pressure gauge joint of the pump, whether the installation is safe, comply with the requirements, whether the flow is correct, whether the anchor bolt and other connecting parts are loose or not.(2) add lubricating oil to the bearing case, and the oil level is 2/3 of the gauge of the bearing box.
- Q: Difference between pump and compressor
- A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. The pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, and also can transport liquid, gas mixture and liquid containing suspended solid. Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to classification according to the working principle, it can be classified and named according to other methods. For example, according to the driving method can be divided into the electric pump and the turbine pump; according to the structure can be divided into single-stage pump and multistage pump; use can be divided into the boiler feed pump and the metering pump; according to the nature of transmission fluid can be divided into water pump, oil pump and mud pump etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps.
- Q: What are the main performance parameters of hydraulic pumps?
- Displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
- Q: What is an industrial water pump?
- Industrial water pump, water pump for industrial production.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
- Q: Significance of water pump model ISO50-160
- According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
