Q:What are the basic technical parameters of the pump?
Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;
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:What is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:Common failure treatment of piston pump
1) overflow valve regulation is too high, overload after the pump2) the overflow valve spool is blocked, the central hole of the valve core is blocked or the overflow valve is blocked by a damping hole, and the overflow is not overflow3) pump outlet one-way valve installed or spool blocked and stuffy pump4) motor fault x091) adjust the relief valve pressure value2) repair valve boring3) overhaul check valve4) overhaul or replace the motor
Q:Why is the sewage pump device coupler?
Automatic coupling installation of sewage pump is a sewage pump with automatic coupler and a guide rod guide chain fixed installation, convenient maintenance, manual maintenance can be directly hung up by the pump coupling device, ordinary sewage pump is generally Mobile
Q:What is the lift of diaphragm pump?
Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
The elevator is mainly used by the power grid through the rectifier, filter, inverter and other transmission to the motor. The motor in high speed when the brake suddenly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power, the reverse voltage and torque original electric state torque instead, and the motor with brake strong torque, forcing the rotor to stop fast but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible and therefore cannot go back to the grid, energy will be accumulated in the filter capacitor, produce pump voltage, this phenomenon of pump voltage converter has great destructive power.
Q:How is the pump level of submersible sewage pump determined?
Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
Q:5 floor water pressure is too low, what kind of water pump is better?
Installed pump flow, lift did not meet the requirements, this will need to re type selection, calculation;
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
The working principle of submersible pumpBefore the pump is opened, the suction pipe and pump must be filled with liquid. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuously from the outflow discharge tube.
