Harish Techno ask every Piston pump users to take down the following items:
Filter hydraulic oil, every month and change hydraulic oil every three months.
Pump should not be started if no cooling water feeding into the pump, in order to prevent ceramic plunger breakage and rubber gasket damage due to overheat or overcool suddenly. Besides ,the cooling water also can be used in ceramic cleaning to prolong plunger and gasket service time.
Sealing ring should not be pressed too tightly, just press it when no leakage.
If plunger pump is not in use in cool winter, please pump out slurry completely from the plunger pump, prevent plunger pump freeze damage
Replace sealing units of hydraulic system and slurry pump on regular interval.
Make sure the plunger pump stroke is long enough, so that the plunger should not impact with the hydraulic cylinder end or changing its direction swiftly
When pressure value is over 0.2Mpa which showed on the air tank pressure gauge, please stop the plunger pump as soon as possible, open the lower valve ,discharge slurry, feed air again.
