Water pressure weighing and drying method for gas cylinder

Abstract

The invention discloses a water pressure weighing and drying method for a gas cylinder. The water pressure weighing and drying method comprises two main procedures, namely a water pressure test accompanying weighing and water pouring and drying after the water pressure test is completed. A turbine elevator is mounted on a water pressure roll-over stand of a testing machine, and a pressure sensor module is fixedly mounted on the inner side of the top of the turbine elevator, so that the turbine elevator is used for controlling the height lifting of a gas cylinder, and a water pressure test and two times of weighing before and after the water pressure test are realized under the condition of single hoisting and feeding; and ventilation switching control and flow direction of drainage drying are improved, so that complete drying and discharging of an inner cavity can be completed at a high speed. According to the application of the method, two times of automatic weighing and reading after hoisting and feeding are achieved on the premise that an existing water pressure test is normally carried out through equipment transformation, meanwhile, the drying process is improved for the gas cylinder subjected to the water pressure test, the drying time is shortened by 50% or above, and better product drying quality and interior appearance quality are obtained with lower production cost and safety risk.

Description

technical field [0001] The invention relates to post-processing equipment for manufacturing industrial gas cylinders, in particular to an improved method for centralized hydraulic testing, weighing and drying of high-weight, long-bodied steel gas cylinders. Background technique [0002] With the improvement of people's requirements for environmental protection, new energy sources such as natural gas and hydrogen will be further developed and utilized. In order to make use of these new energy sources more conveniently, industrial gas cylinders dedicated to storing special gases have been developed, and industrial high-pressure gas cylinders matching them have emerged as the times require. As a special high-pressure container, this kind of industrial high-pressure gas cylinder not only needs special production technology and customized equipment to produce, but also has supporting technical solutions for testing whether these gas cylinders meet the standards, hydraulic pressur...
