Petroleum drilling rigs are used for identifying geologic reservoirs and for creating wells for extraction.The mud pumps of drilling rigs are operated g35 coupe fender at high mud rates to make possible the drilling process.The durability of the mud pump valves to erosive wear, due to the action of abrasive drilling fluid containing solid particles, depends on their constructive markbroyard.com form and on the mud flow velocity.This paper analyzes a few methods of increasing the wear resistance of mud pump valves.
