Maintenance of agricultural water pumps (1) After the agricultural water pumps are stopped, they must drain the water left in the pumps and pipes and clean them up. The stainless steel water pumps should also clean the external mud at the same time so as to prevent the frozen water and frozen pipes from bursting the pump body and water pipes. .
(2) For cast iron parts such as bottom valve and elbow of the pump, the iron brush shall be brushed with a wire brush, painted with anti-rust paint and then painted. After drying, it shall be placed in a dry room or storage room for ventilation.
(3) Belt-driven, after the belt is unloaded, rinse it with warm water, dry it, hang it in a dry place with no direct sunlight, and do not store it in places with oil, corrosives, and smog. Under no circumstances should the belt be covered with oils such as oil, diesel or gasoline, and do not coat the belt with rosin and other sticky substances. Before the belt is used for the next year, it is absolutely necessary to thoroughly remove the bai powder from the belt contact surface.
(4) Check ball bearings, such as inner wear, tamping, ball wear, or spotted surfaces. Replace the bearing with the available gasoline or kerosene that does not need to be replaced, butter it, and reinstall it.
(5) The screws and bolts to be removed should be cleaned with a wire brush and diesel oil, and coated with oil or butter, re-installed or wrapped in plastic cloth, or they can be stored in diesel oil to avoid rust or loss.
Chloromethane also called Methyl Chloride. It was once widely used as a refrigerant. It is a colorless extremely flammable gas with a mildly sweet odor. Due to concerns about its toxicity, it is no longer present in consumer products. Chloromethane was a widely used refrigerant, but its use has been discontinued due to its toxicity and flammability. Chloromethane was also once used for producing lead-based gasoline additives. The most important use of chloromethane today is as a chemical intermediate in the production of silicone polymers. Smaller quantities are used as a solvent in the manufacture of butyl rubber and in petroleum refining.
