Skirt valve delivery pump drag pump and pump truck to the conveying of building top containing the concrete of stone time,
It is possible to that this thing happens.
3. the build-ups of pressure such as pumping equipment, conveyance conduit and pipeline valve can be impacted by the pressure of pulsation, and
And the material backflowed in the duct also can produce bigger because of water hammer effect when stopping or commutating suddenly
Impulsive force, make pumping equipment, conveyance conduit, pipeline valve etc. by more violent impact.
The pressure of pulsation and the impulsive force of water hammer effect make stressed member be susceptible to fatigue and damage, and then
Affect its reliability and service life, and bring serious potential safety hazard.
4. in some application material, it is desirable to have metastable when with pipeline conveying material
Pressure or flow, these twin-tub delivery pumps existing are due to inevitable pressure and flow pulsation, it is clear that also
Can not be met it and use requirement, such as when for coal water slurry boiler conveying coal water slurry fuel, if it occur that flow
Pulsation, may result in when flow-reduction or interruption and interrupts burning because of undercharge, cause blowing out event
