Abstract
The invention relates to a hydraulic testing machine and a testing method of a pressure gas cylinder, which can carry out automatic pressure measurement and evacuation on the pressure gas cylinder. The testing method comprises the following steps: firstly, a central tube is inserted into a steel cylinder by a central tube joint and then is positioned at a cylinder opening, a controller commands an abutting air cylinder to enable a pressure test head to press the cylinder opening and close an air inlet valve and a drain valve simultaneously as well as open an exhaust valve and a water inlet valve to pour water into the cylinder, the controller commands to close the exhaust valve and the water inlet valve when the effluent water of an exhaust tube does not carry gas, a pressure test pump is started for boosting and automatically stops when the pressure reaches 3.2MPa, the pressure is kept, a condition that the steel cylinder has no leakage is checked after the pressure is kept for 0.5-2 minutes, then pressure relief can be carried out, the drain valve and the air inlet valve are sequentially opened to carry out pressure relief and drainage, the air inlet valve is closed when a drainage outlet is completely drained and only air exists, the pressure test head is raised to carry out the pressure test of the steel cylinders of the next batch, and the operation is circularly carried out in such a way.
Description
Technical field
The present invention relates to a kind of pressure gas cylinder hydrostatic testing machine and the test method that can carry out automatic voltage measurement, emptying to pressure gas cylinder, belong to band air bottle test unit and make the field.
Background technology
At present, to the detection of existing pressure gas cylinder, employing be that manual detection cooperates detection with tensimeter.Its weak point: the one, accuracy of detection is not high, poor reliability; The 2nd, can't realize the emptying of bottle interior air, not only influence the volume of rock gas, and have huge potential safety hazard.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind ofly can detect automatically pressure gas cylinder, emptying and precision height, pressure gas cylinder hydrostatic testing machine and test method that reliability is high automatically.
Design proposal: in order to realize above-mentioned purpose of design.The application aims at and makes and overhaul the usefulness that liquefied petroleum gas steel cylinder is done water pressure test for strength, be applicable to the hydraulic testing of YSP-15 and YSP-10 shaped steel bottle, on structural design, the application is by host rack, clamping cylinder, pressure text head, gas, water lines, valve, controller compositions such as (promptly handling screen), test pump is joined in addition; By hydraulic pressure sensor, negative pressure transducer and pressure transducer are set at pressure text head, the signal of hydraulic pressure sensor, negative pressure transducer and pressure transducer collection is inputed to controller and handles, compares, assigns instruction by host CPU in the controller, and by being built in the driving circuit in the controller, the control test pump air pump that opens or closes, controls that reaches the feed pipe water supply valve that whether supplies water opens or closes, controls clamping cylinder pressure size to the vacuum tightness value of gas cylinder negative pressure ventilation and air valve.
Technical scheme 1: the pressure gas cylinder hydrostatic testing machine, frame is provided with the person in charge, and clamping cylinder is positioned at the frame upper surface, and the piston rod end in its clamping cylinder is connected with pressure text head, and the pipe core joint is positioned at the below of pressure text head and supporting with the pressure gas cylinder mouth.
Technical scheme 2: pressure gas cylinder hydraulic test method; earlier pipe core is inserted in the steel cylinder by the pipe core joint; in place then and bottleneck is located; the controller instruction holds out against cylinder pressure text head is compressed bottleneck simultaneously; close gas admittance valve and draining valve; open vent valve and water intaking valve is poured water in bottle; when treating that the gas outlet water outlet does not have gas entrainment; vent valve and water intaking valve are closed in the controller instruction; starting test pump boosts; test pump auto stop pressurize when making pressure to 3.2MPa; pressurize checks after 0.5～2 minute that the steel cylinder ne-leakage gets final product pressure release, opens draining valve more successively; gas admittance valve carries out the pressure release draining, when treating that the whole emptyings of freeing port have only air; close gas admittance valve; pressure text head is risen, carry out the pressure testing of next group steel cylinder, so circulation is carried out.
The present invention compares with background technology, and the one, by hydraulic pressure sensor, can accurately know the gas cylinder artesian condition, guarantee the safe reliability that gas cylinder uses; Two by pressure transducer, can accurately know the phenomenons such as whether producing gas leakage that cooperates between pressure text head and the pipe core joint, guarantees to detect the reliability of data; The 3rd, compare by the gas cylinder vacuum values of negative pressure transducer and setting in advance, can guarantee the once more gas injection of gas cylinder under the emptying situation, avoided unsafe hidden danger.
