手动试压泵体积小、重量轻、运输方便、操作简单、使用方便、维护简单,广泛应用于煤炭、冶金、石化、电力、机械等行业,是一种简单方便的液压动力源。市场上现有手动试压泵一般为柱塞泵,有单级与双级两种形式,它的所有阀通常都集中在柱塞泵上,结构相对紧凑。换向阀与柱塞泵分为2个独立的部件,但可组合使用。单级柱塞泵的结构相对简单;双级柱塞泵有两种不同的结构形式,一种是串联形式,另一种是并联形式。
Manual pressure test pump is small, light weight, easy to transport, easy to operate, easy to use, easy to maintain, widely used in coal, metallurgy, petrochemical, power, machinery and other industries, is a simple and convenient hydraulic power source. Existing manual pressure test pump on the market is generally a piston pump, a single-stage and two-stage two forms, all of its valves are usually concentrated in the plunger pump, the structure is relatively compact. Directional valve and piston pump is divided into two separate components, but can be used in combination. Single-stage piston pump structure is relatively simple; two-stage piston pump has two different forms of structure, one is in series, the other is in parallel.
