多年来我国煤田钻探的泥浆泵安全阀,结构陈旧,零件容易损坏,现场常因泥浆泵无可靠的安全防护,造成机械事故。针对这一问题,我们在参考国内外各种泥浆泵安全阀的基础上,设计试制成功弹簧滚轮式安全阀。本文就其特点、结构原理及设计计算问题作一介绍。 Over the years our coal mine drilling mud pump safety valve, outdated structure, easy to damage parts, the scene often due to mud pump without reliable safety protection, resulting in mechanical accidents. In response to this problem, we reference a variety of mud pump safety valve at home and abroad on the basis of the design of a successful spring-loaded safety valve. This article on its characteristics, structural principles and design calculations made an introduction.
