How to clean the concrete pump pipeline Before cleaning the pipeline, it is best to pump 0.5-1 cubic meters of mortar, and all pump finished. Finally shut down, turn the plate valve switch, remove the accumulator pressure. There are two ways to clean the pipe: washing and air washing. Whether it is water or air wash, the valve box and hopper should be cleaned. Washed, the water soaked cylindrical cement bag and cleaning balls have been installed into the cone has been cleaned, connected to the cone, pipe, close the discharge door, and then filled with water to the hopper (to be maintained Water constantly). Pump water until the cleaning ball exits the front of the duct. Air wash that is compressed air purge, the soaked water cleaning ball first plug into the gas wash joint, and then connected to the adjustable tube of the first straight pipe, and the end of the pipe connected safety cover, safety cover The orifice should face down. Control the pressure of compressed air does not exceed 0.8MPa, the valve should be slowly opened, when the concrete can flow out smoothly before opening the atmosphere valve. Air wash is completed, to immediately close the valve wash requires cutting ring and the eye plate (butterfly valve pump is required plate valve and tie rod and the upper and lower wear-resistant film) the gap is small and requires a lot of water, to seal the ball clean After the water does not penetrate forward. Near the end of the washing, pay attention to the water pipe, do not flow to the concrete pouring sites to affect the quality of concrete. This method is simple, less dangerous, more commonly used. Air washing need to be equipped with air compressors, to be strictly in accordance with the provisions of the operation. Require good pipe sealing. But not too far, long-distance cleaning can be segmented. This method of operation cautious, dangerous, so construction workers should be far away from the exit direction, to prevent the pellets or ball cleaning flew wounding.
Grooved Pipe Fittings are the part that plays the role of connecting, reducing, turning and branching in the pipe system. The pipe used for the connection of the fire-fighting pipe is the fire-fighting pipe.
