Before cleaning delivery line, it is best 0.5-1m3 mortar pumping, and then finished all down, then flip the switch plate valve, remove the accumulator pressure.
There are two ways to clean concrete pump bend pipe that water wash and gas wash , whether water or gas wash, should the valve housing and hopper clean. When washing, you should open the cone and cleaned, soaked with water and then tied into a cylindrical cement bags and cleaning the ball has been cleaned of the cone into the tube, followed by back taper pipe and tubing, closed Doumen unloading, again hopper filled with water (water should be kept constant); pumping water until clean ball out from the front of the duct so far.
Water Wash, requires cutting ring and eye plate (butterfly valve plate valve and the pump is Tied up and down wearable pieces) gap is smaller, the need for large amounts of water, tightly sealed, so that water does not penetrate after cleaning ball forward . When washing the end, we should pay attention to the line in the water, do not place concrete pouring flow through to avoid affecting the quality of the concrete. This method is simple, less dangerous, more commonly used.
Gas wash, which uses compressed air purging, it is soaked in water before washing ball into the air wash joints, followed by contact with adjustable straight first root canal, and at the end of the pipe connected to the safety cover, (safety cover opening is down). When the gas washing, control air pressure must not exceed 0.8MPa; slowly open the valve, when the concrete can be successfully open a large outflow valve; after air wash is completed, the valve must close immediately. Air compressor with air wash needs to operate in strict accordance with the regulations, require concrete pump pipeline tightness, but could not wash the air wash long lines, long-distance pipeline should be segmented for cleaning, this method should be careful operation, more dangerous, so the construction workers to stay away from export orientation to prevent pellets or cleaning ball flying wounding.
