Abstract

The invention provides a four-column guiding type pressurizing device of a hydrostatic testing machine. The four-column guiding type pressurizing device comprises four guiding columns which are vertically arranged, wherein a pressure bearing plate, a lifting plate and a positioning plate are sequentially installed on the four guiding columns from top to bottom. A second hydraulic cylinder and at least two return stroke standard hydraulic cylinders are installed at the lower end of the positioning plate, a first hydraulic cylinder with no oil port is arranged in the second hydraulic cylinder, the upper end of the first hydraulic cylinder is fixedly connected with the lifting plate, a tubular plunger is vertically arranged in the first hydraulic cylinder, the upper end of the plunger sequentially penetrates through the positioning plate, the lifting plate and the pressure bearing plate to be fixedly connected with the pressure bearing plate, the lower end of the plunger is arranged in the first hydraulic cylinder, the return stroke standard hydraulic cylinders are all connected with the lifting plate and drive the lifting plate to drive the first hydraulic cylinder to move vertically in the vertical direction. The four-column guiding type pressurizing device improves the pressure in a tube to testing pressure fast and stably by adopting an automatic speed control pressurizing mode, is novel and compact in structure, reasonable in layout, high in specific pressure, large in capacity, fast and stable in boosting and improves the safety and stability of the system.

Description

Technical field [0001] The present invention is the technology field of hydraulic testing equipment. It involves a supercharged device necessary to resist the pressure test for boiler steel pipes, petroleum oil well pipes, pipeline pipe pipes, etc., and specially involves a four -column -guided voltage booster device of a hydraulic test machine.Essence Background technique [0002] With the growth of the industrial and agricultural production and service industry worldwide, the development of the transportation industry, and the improvement of people's living standards, the market demand for energy such as oil and natural gas such as oil and natural gas has expanded.In recent years, oil exploration and development, especially natural gas development, has continued to expand the demand for oil pipes and pipes.According to the requirements of the SY / T 6194 "sleeve and oil pipe", oil oil use of oil, the suite factory, and before using the static water pressure test.Due to the develo...
