Problems solved by technology

When the diameter of the ductile iron pipe is greater than DN1600mm, due to the large geometric size of the ductile iron pipe, the structure of the hydraulic machine is also huge. When the hydraulic test level is increased, the difficulty of equipment transformation is also increased. At the same time, the existing hydraulic test technology is in the In the test of large-diameter ductile iron pipes, the problems of large water intake, long time and low efficiency

Abstract

The invention discloses a supercharging test apparatus and a use method thereof, and relates to the technical field of hydraulic pressure test apparatuses. The apparatus comprises a jack floating seal assembly, a bell mouth seal assembly and an inner container, the jack floating seal assembly is arranged on the push head of a hydraulic pressure testing machine, the bell mouth seal assembly is arranged on a fixed baffle wall arranged at one end of the hydraulic pressure testing machine, and the inner container is arranged in the chamber of a tube to be tested. The apparatus greatly shortens the water feeding and draining time in the hydraulic pressure test process in order to shorten the integral time of the hydraulic pressure test and improve the efficiency of the hydraulic pressure test, and also can improve the grade of the hydraulic pressure test.

Description

technical field [0001] The invention relates to the technical field of hydraulic test devices, in particular to a booster test device and a method for using the same. Background technique [0002] In order to ensure the quality and mechanical properties of ductile iron pipes, GB1325-2013 stipulates that ductile iron pipes must be hydrostatically tested one by one according to the specified pressure. When the diameter of the ductile iron pipe is greater than DN1600mm, due to the large geometric size of the ductile iron pipe, the structure of the hydraulic machine is also huge. When the hydraulic test level is increased, the difficulty of equipment transformation is also increased. At the same time, the existing hydraulic test technology is in the The test of large-diameter ductile iron pipes showed the problems of large water intake, long time and low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a ...
