Equipment Description:
The YS-8C/12 type liquefied petroleum gas cylinder hydrostatic test machine is primarily used for conducting pressure resistance strength tests on liquefied petroleum gas cylinders. The equipment is designed and manufactured in accordance with GB/T9251-2011 "Hydrostatic Test Method for Gas Cylinders" and GB5842-2006 "Liquefied Petroleum Gas Cylinders". It is a fully automated device specifically designed for hydrostatic testing of liquefied petroleum gas cylinders. The equipment has the following main functions:
The equipment employs PLC programming control, automating all operations.
Throughout the testing process, the subject cylinder is positioned and clamped once, sequentially completing the steps of filling the cylinder with water, conducting the hydrostatic test, and draining the water.
The equipment is equipped with an electric contact pressure gauge, which allows for timely pressure relief in case of overpressure. Thanks to these multiple protective features, the safe operation of the equipment is ensured.
The device mainly consists of a frame, a hydrostatic test pipeline system, a pneumatic control pipeline system, a cylinder positioning device, a cylinder conveying system, a water circulation and filtration system, an electrical control system, and a software system.
1. Frame
The frame serves as the installation carrier for all components of the equipment.
2. Hydrostatic Test Pipeline System
2.1 The hydrostatic test pipeline system includes all pipelines, valves, and the water filling pump required for filling, hydrostatic testing, and draining.
2.2 The configuration of the pipeline system enables the operations of filling the cylinder, conducting the hydrostatic test, and draining the water to be completed under a single positioning and clamping condition. Through coordination with the electrical system, the automation of these actions can be achieved.
2.3 In the pipeline system, the central rod adopts an elastic and retractable structure, which can adapt to a certain degree of deviation in cylinder height, ensuring that the water inside the cylinder is completely drained after the hydrostatic test.
2.4 In the pipeline system, the test pressure inside the cylinder is displayed with a one-gauge-one-valve configuration for each cylinder, allowing for accurate and independent monitoring of the pressure retention status of each tested cylinder.
2.5 The pipeline system is equipped with a precision pressure gauge, which can be used to calibrate other pressure measurement instruments in the system.
2.6 The pipeline system is equipped with an electric contact pressure gauge, enabling overpressure protection for the system.
