Embodiment Construction

[0015] The present invention will be further described below in conjunction with specific embodiments.

[0016] Such as figure 1 , this example includes a horizontally arranged disc-shaped turntable 9, and the turntable 9 has a central axis mechanism 3 connected to its installation station. Below the turntable 9, a pool is arranged. An autorotation machine 5 for driving the rotation of the turntable is installed on the turntable 9. The autorotation machine 5 includes a motor and a reducer connected with the motor transmission. The reducer drives the central axis mechanism 3 through gears to drive the turntable 9 to rotate.

[0017] Several test benches 1 for testing the hydraulic pressure of steel cylinders are installed in the circumferential direction near the outer edge of the turntable 9 . Such as figure 2 As shown, the test bench 1 includes a fixed bracket 16 fixed on the turntable 9 , and an overturn bracket 17 connected to the fixed bracket 16 through an overturn sh...

Abstract

The invention provides a rotary hydrostatic testing machine for steel bottles of liquefied gas, which comprises a horizontally arranged disc-shaped turntable (9); a plurality of test beds (1) for testing hydraulic pressure of the steel bottles are arranged on a position of the turntable (9) close to an outer edge in the circumferential direction; and the turntable (9) is also provided with a high-pressure hydraulic pump (2) connected with the test beds (1) through water pipes, a hydraulic station (4) connected with the test beds (1) through oil pipes, a self-rotating machine (5) used for driving the turntable to rotate, and a self-sucking pump (8) connected with the test beds (1) through water pipes. The prior (8hr) 600 steel bottles per shift are improved to 2,400 steel bottles per shift in hydrostatic tests for the steel bottles of liquefied gas. The rotary hydrostatic testing machine greatly lightens the labor intensity of operators; and the test process is more standard, and test results are more reliable.

Description

(1) Technical field [0001] The invention relates to a hydrostatic testing machine for a liquefied gas cylinder, in particular to a rotary hydrostatic testing machine for a liquefied gas cylinder. It is mainly used to continuously test the water pressure resistance of liquefied gas cylinders. (two), background technology [0002] As a pressure vessel with high safety requirements, the test of liquefied gas cylinders includes hydrostatic test. The main purpose of the hydrostatic test is to check whether the bottle body and welds have leakage and whether the bottle body has macroscopic deformation. [0003] At present, there is no testing machine with a high degree of automation for the hydraulic test of liquefied gas cylinders. The current test method relies more on manual operation, which not only has high labor intensity and low work efficiency; but also has poor operation standardization and unsatisfactory accuracy of test results. (3) Contents of the invention [0004...
