Introduction to the Suction principle of IS ISR End Suction Pump
The Suction principle of IS ISR End Suction Pump means to start the pump when the suction pipe does not need to be filled with liquid (but there must be enough liquid in the pump body). The pump itself can automatically remove the gas in the suction pipe and then enter the normal operation; Enough liquid must be filled at the first start, and the liquid stored in the pump body will ensure that the pump can start again when it is started later.
The Suction time of IS ISR End Suction Pump refers to the shortest time required from the start of the pump to the pressure stabilization when the pump is pumping clean liquid at room temperature and the installation height is the allowable suction vacuum minus 0.5, that is, the pump exhausts the air in the suction pipe The time required. For the centrifugal IS ISR End Suction Pump, the length of the suction pipe between the suction surface and the pump inlet should be less than the pump installation height plus 20D (the diameter of the suction pipe hole); for the vortex IS ISR End Suction Pump, the suction surface and the pump The length of the suction pipe between the inlets should be less than the installation height of the pump plus.
Ordinary centrifugal pumps are equipped with a bottom valve at the lowest end of the suction pipeline, and more water is needed to fill the entire suction pipeline before starting. The bottom valve often fails due to inclusion of debris or loose closure of itself. Eliminate these failures Sometimes it takes a lot of labor, especially in winter.
The suction port of IS ISR End Suction Pump is generally higher than the impeller suction port. It can be started as long as the pump body is filled with water, without the above-mentioned defects. For labor, it is very convenient to use IS ISR End Suction Pump for mobile irrigation, mobile work, frequent startup, and difficult watering situations. IS ISR End is used in many places such as agriculture, construction, tank truck unloading, oil depots, firefighting, and shipbuilding. Suction Pump.
