A pneumatic steel pipe hydraulic testing machine

Abstract

The invention belongs to the technical field of using hydraulic test machine tools, in particular to a pneumatic steel pipe hydrostatic testing machine which comprises a base plate, wherein the base plate is provided with a support which is provided with a cylinder, the cylinder is connected with an upper clamping die, a lower clamping die is arranged at the position, below the upper clamping die, on the base plate, and the upper clamping die and the lower clamping die are mutually clamped in a matched mode; a shaft is fixed on the lower portion of the base plate, and shaft wheels are arranged at two ends of the shaft; a plurality of L-shaped limiting plates are arranged on the side portion of the base plate, and the L-shaped limiting plates are provided with side wheels; and the base plate is provided with a sealing seat which is provided with a threaded rod, a sealing plate is arranged at one end of the threaded rod, and the upper clamping die and the lower clamping die are closed and then arranged beside the sealing plate in a coaxial mode. By means of the pneumatic steel pipe hydrostatic testing machine, the position of the overall hydrostatic testing machine can be very conveniently and fast adjusted in a labor-saving mode according to the requirements of actual testing tubes, and therefore the tightness of the overall hydrostatic testing machine is enabled to be excellent.

Description

technical field [0001] The invention belongs to the technical field of hydraulic testing equipment, and in particular relates to a pneumatic steel pipe hydraulic testing equipment. Background technique [0002] The hydraulic testing machine is to inject water into the steel pipe through the water pump, so that the water pressure in the steel pipe reaches the test pressure, and check whether the container is leaking. And the structure of the hydrostatic testing machine that is used for detection in the present steel pipe enterprise generally comprises a positioning plate, is then provided with threaded rod on the positioning plate, and one end of the threaded rod is connected with seal. When in use, the entire positioning plate is fixed in a water tank, the positioning plate is fixed by the splints on both sides of the water tank, and then the threaded rod is rotated to seal the pipe. This type is a relatively simple hydraulic testing machine, which can adjust the position o...
