Daily Cleaning Methods

Each time after the completion of construction, the remaining concrete in concrete pump pipe should be timely cleaned. Daily cleaning will greatly extend the service life of the concrete line pump truck.

Before cleaning, it is recommended to pump 0.52-1m3 of mortar. Stop after all pumping. Flip the plate valve switch and then remove the pressure of the accumulator.

There are two cleaning ways, water cleaning and air cleaning. It is worth mentioning that no matter in which way, the valve box and the hopper should be thoroughly cleaned.

Air cleaning with certain danger, requires strict pipe tightness and the cleaning length is not too far.

While water cleaning is easy and safe, which is recommended widely.
