The thrust bearing of the flat valve of manual water well drilling rig accessories uses lithium-based grease. The consumption of grease should be checked after each maintenance. If it is found to be deteriorated, contaminated or missing, it should be replaced or replenished immediately. The valve cavity should be replaced in time during each maintenance. Flush and refill sealing grease to lubricate the valve plate and valve seat. During the maintenance process, if slight leakage occurs at the valve stem seal packing seal, sealing grease can be injected through the sealing grease injection valve on the valve cover to prevent leakage, but the seal should be replaced in time after the construction is completed. Before refilling the valve with sealing grease, you must first consider the internal pressure of the valve body. The pressure of the high-pressure injection gun used must be greater than the internal pressure of the valve to successfully inject sealing grease. Load 7903 sealing grease into the injection gun and connect it to the injection valve on the valve cover through a hose. Operate the injection molding gun and inject sealing grease.
