摘　　要：泥浆泵是地质钻探设备的心脏,它是固井、压裂、酸化等作业中的关键设备之一,在矿山开采行业中起着重要作用,泥浆泵的性能、结构、可靠性、适应性、经济性以及使用寿命直接影响着矿山开采质量的好坏。泥浆泵早期的典型结构是双缸双作用泵,这种泵在使用时,可靠性较高,但是重量和体积都偏大,而且压力波动大、效率低。随后出现的矿用三缸单作用泥浆泵较好地解决了这些问题,经过三十多年的不断改进和完善,在性能、结构、可靠性、适应性与经济性等方面,已经走向成熟,使用效果也很显著。但是,这种泵也有其本身无法克服的缺点,比如:冲程短,冲次高,在不适合的冲次范围内工作,致使液力端寿命短;泵压偏低,不能完全满足现代矿山开采的需要。为解决现有泥浆泵的主要缺点,提高泥浆泵使用效率,主要应进行基本参数的合理选择和结构设计优化。Mud pump is the heart of geological drilling equipment. It is one of the key equipment in cementing, fracturing,acidizing and other operations, and plays an important role in the mining industry. The performance, structure, reliability,adaptability, economy and service life of mud pump directly affect the quality of mining. The typical structure of the early mud pump is a double cylinder double acting pump. When using this type of pump, its reliability is high, but its weight and volume are relatively large, and its pressure fluctuation is large and its efficiency is low. The following mining triplex single acting mud pump has solved these problems. After more than 30 years of continuous improvement and improvement, it has become mature in terms of performance, structure, reliability, adaptability and economy, and has achieved remarkable results. However, this kind of pump also has its own shortcomings that cannot be overcome, such as: short stroke, high stroke, working in an unsuitable stroke range, resulting in short life of the hydraulic end;The pump pressure is too low to fully meet the needs of modern mining. In order to solve the main shortcomings of the existing mud pump and improve the use efficiency of the mud pump, the reasonable selection of basic parameters and structural design optimization should be mainly carried out.
