FIELD: engines and pumps. ^ SUBSTANCE: device refers to hydraulic machines for volume driving, more specifically to driven devices including hydraulic and pneumatic assemblies and can be used for lifting of liquid from a considerable depth. A hydraulic drive of a well pump comprises driven cylinder equipped with a frame to assemble the said cylinder on a well, pipe line for working liquid supply connected to the pipe, and pipe line for working liquid drainage. The frame made as a tripod fabricated of pipes, one of which is a component of the working liquid supply pipeline, while the second or the rest two are components of the drainage pipe line. ^ EFFECT: increased usability of assembly and maintenance of a drive at operation, reduced effect of compressing loads and intensive cooling of worked out working liquid. ^ 2 dwg |
