Language：
The pipeline disassembly and assembly equipment system is m*nly composed of cont*ners, pumps, pipelines, valves, instruments, disassembly and assembly tools, pressure testing equipment, tool and material shelves, etc. The system not only exercises the pipeline disassembly and assembly capabilities of chemical equipment, but also tr*ns the installation of chemical automation instruments and pump bodies.
1. System features
(1) Used to tr*n students to disassemble and assemble common pipelines and fittings in chemical production.
(2) The system facilitates the assessment of students’ ability to select accessories, disassemble and assemble, operate the device, complete tasks, etc., and has corresponding judgment criteria and methods.
(3) The system provides sufficient optional accessories, disassembly and assembly tools, equipment for inspecting operation, etc.
(4) Parts that are frequently disassembled and assembled must be solid and durable, convenient for students to use for a long time, and able to provide updated equipment.
2. Functions of the system
(1) Reading of flow charts.
(2) Be able to accurately fill in the material list of specifications, models and quantities of pipes, fittings, valves and instruments required for pipeline installation based on the provided fluid transportation flow chart.
(3) Be able to correctly collect the required materials according to the materials list.
(4) Be able to accurately list the tools and consumables required for assembling pipelines and collect the tools and consumables correctly.
(5) Capable of assembling pipelines.
(6) Capable of conducting pipeline pressure testing.
(7) Capable of dismantling pipelines.
(8) Ability to comply with safety regulations during pipeline disassembly and assembly.
3. Pipeline disassembly and assembly tr*ning content
(1) Pipeline assembly
(a) Processing of pipe threads and use of dies.
(b) Install the pipeline according to the pipeline schematic diagram. During installation, ensure that it is horizontal and vertical, with a horizontal deviation of no more than 15 mm and a vertical deviation of no more than 10 mm.
(c) When flanges and threads are connected, the parallelism and concentricity of each p*r of flanges must meet the requirements. When threads are connected, the direction of the raw tape winding must be correct and the thickness must be appropriate. When the threads and pipe fittings are engaged, they must be aligned and aligned, and the tightening force must be moderate.
(d) Valve installation: Before installing the valve, clean the inside of the valve and close it before installation. Directional valves must match the flow direction of the medium. The handwheel position of the installed valve must be convenient for operation.
(e) Installation of flow meter, pressure gauge and filter should be carried out according to specific installation requirements. Pay attention to the flow direction and make sure the position of the scale is easy to read.
(2) Water pressure test
Be able to use a hand-operated pressure test pump and complete the pressure test operation according to the required pressure test procedure. There is no leakage at all interfaces of the pipeline under the specified pressure and within the specified time.
(3) Pipeline disassembly
The process can be carried out in order, generally from top to bottom, first the instrument and then the valve. The pipe fittings and instruments must not be damaged during the disassembly process. The disassembled pipes, pipe fittings, valves and instruments should be classified and put away.
4. System configuration list
The system consists of the following five parts: 1. Pipeline disassembly and assembly object system; 2. Pipeline disassembly and assembly tools (including pressure test and leak detection equipment); 3. Pipeline disassembly and assembly shelves; 4. Pipeline disassembly and assembly spare parts.
