Description
技术领域
本实用新型涉及一种带有蜗轮蜗杆减速器的油井作业用三缸柱塞泵。
背景技术
在现有技术中,油井作业用三缸柱塞泵是由外部动力输入到齿轮副减速器,然后传递到曲轴,由曲轴连杆十字头机构将曲轴的回转运动转化为十字头的直线往复运动,利用柱塞在密闭腔内的往复运动经吸入阀吸入液体,排出阀排出至作业管路。这种设备的减速器为齿轮副减速器,客观上存在:减速比小,无法传递大扭矩。因此,限制了泵的排出压力和排出功率,使用范围窄。
实用新型内容
本实用新型的目的是提出一种带有蜗轮蜗杆减速器的油井作业用三缸柱塞泵,来解决背景技术存在的:齿轮副减速器减速比小,无法传递大扭矩,从而限制了泵的排出压力和排出功率,导致使用范围窄。解决上述问题所采用的技术方案是:一种带有蜗轮蜗杆减速器的油井作业用三缸柱塞泵,由减速器、滑动于泵阀箱内的柱塞盘根系统、将减速器的回转运动转化为柱塞的直线往复运动的曲轴连杆十字头机构组成,曲轴连杆十字头机构包括十字头缸体以及在其内滑动的十字头,曲轴为四点支撑,其特征在于减速器为蜗轮蜗杆减速器,泵阀箱为分体式,吸入阀和排出阀集成于泵阀箱内。其中,蜗轮蜗杆减速器设置于泵体的一侧。曲轴用四个轴承支撑。本实用新型与背景技术比较所具有的有益效果是:由于采用上述技术方案,利用蜗轮蜗杆减速器减速比大,适合传递大扭矩的特点,增加了泵的排出压力和排出功率,使得使用范围拓宽。并且泵的泵阀箱为分体式,吸入阀、排出阀集成于泵的内部,因此其体积小,重量轻,易于拆装,特别适合野外油井作业和海洋平台油井作业。
