Equipment usage, working principle and characteristics
The external test method hydraulic test line is a test equipment used to detect the residual deformation rate of gas cylinders, including weighing, watering, testing (measurement of residual deformation rate), loading and unloading, water discharge, and drying.
The hydraulic test section of the pipeline should be automatically carried out by the computer controlled test process, and automatically complete the pressure increase (self-tightening pressure), pressure holding, pressure relief, pressure increase (water pressure test pressure), pressure holding, and pressure relief; through the computer Collect hydraulic test pressure data and pre-tightening pressure data, and automatically calculate the residual deformation rate. The entire hydraulic test process is automatically completed, and related test data and graphs can be stored.
Its working principle is: put the test bottle in a special water jacket, and use a high-pressure pump to pressurize the test bottle.
After reaching the set pressure, it automatically enters the pressure-holding state, and the pressure test is performed on the tested bottle. At the same time, the gas cylinder expands under the test pressure, squeezing a part of the water in the water jacket into the measuring cup, so that the The amount of water increases, and the increased amount of water is the full deformation of the cylinder (automatically transmitted to the industrial computer). After the cylinder is depressurized, the elastic deformation disappears, so the water in the measuring cup returns to the water jacket, but the water in the measuring cup is still It is more than before the cylinder is pressurized. The extra water is the volume residual deformation of the cylinder (automatically transmitted to the industrial computer), and the ratio of the volume residual deformation to the total deformation is the volume residual deformation rate of the cylinder.
The flexible guide rail conveying hydraulic test line is equipped with a smart flexible guide rail suspension conveyor, which can realize manual fixed-point horizontal conveying, electric hoist lifting, easy, convenient, stable and reliable.
This machine is simple to operate and easy to maintain. It is fully developed in accordance with the national standard GB/T9251-2011 "Cylinder Pressure Test Method" and the American DOT standard. It is an ideal selection equipment for natural gas cylinders and seamless gas cylinder manufacturers and testing units.
