The function of the dust ring is to prevent dirt in the washing chamber from entering the concrete seal assembly.
● Before each pumping, fill the washing room with clean tap water. When the outside temperature is below 30 degrees, you can add about one-third of waste hydraulic oil to improve the lubrication effect.
● Keep the washing room clean and do not allow any deposited dirt, otherwise it will easily cause damage to the cylinder piston rod and the delivery cylinder.
● If the water in the washing room is turbid, the concrete seal should be replaced immediately.
● If the water temperature is too high during pumping, please replace it with new water in time, otherwise it will easily wear the concrete piston and delivery cylinder.
● After pumping, unscrew the water-draining rubber plug, drain the water in the washing room, remove the piston for cleaning and inspection, and apply grease on the concrete piston when putting it in.
● When the ambient temperature is below 0 degrees, the water in the washing room must be drained after the construction is completed.
Special tips:
● The best time to replace the concrete seal: when the water in the washing room is extremely turbid and mortar leaks during pumping.
● The best time to replace the delivery cylinder: when the service life of the concrete seal is about 4,000 cubic meters and the delivery cylinder is worn
