Analysis: installation and debugging equipment flow of chemical fiber multifunctional composite spinning testing machine

The following is an analysis of the installation and debugging equipment flow of the multifunctional composite spinning testing machine for chemical fiber:

Preparation before installation

Site preparation: Choose a suitable installation site, requiring the ground to be flat and dry, the surrounding environment to be clean, free from vibration sources and strong electromagnetic interference, and sufficient space to facilitate the installation, operation and maintenance of the equipment.

Equipment inspection: After the arrival of the equipment, carefully count all parts according to the delivery list, check whether the equipment is damaged, deformed or missing parts, and check whether the accompanying technical materials, such as instructions and drawings, are complete.

Preparation of tools and materials: Prepare tools needed for installation, such as wrenches, screwdrivers and vernier calipers, and necessary materials, such as gaskets, bolts, nuts and sealant.

Installation process

Foundation installation: according to the requirements of the equipment manual, pour the equipment foundation to ensure that the size, flatness and levelness of the foundation meet the specified standards. After the foundation is solidified, all parts of the equipment are hoisted to the corresponding positions, the equipment is leveled by adjusting the shim, and the equipment is fixed on the foundation with anchor bolts.

Assembly of mechanical parts: according to the equipment drawings, install the spinning box, metering pump, spinneret assembly, winding mechanism and other mechanical parts in turn to ensure that the installation positions of all parts are accurate, the connection is firm, and the transmission parts are flexible and free from sticking. In the installation process, it is necessary to use measuring tools for measurement and calibration to ensure the installation accuracy of all components.

Electrical system installation: the electrical lines connecting the equipment, including power lines, control lines, sensor signal lines, etc. Install the electrical control cabinet, and install all electrical components in the cabinet, wiring and wiring according to the circuit diagram. After the wiring is completed, check whether the wiring is firmly connected, whether there are any problems such as short circuit and open circuit, and conduct insulation tests to ensure the safety and reliability of the electrical system.

Installation of pipeline system: install pipeline system for conveying chemical fiber raw materials, cooling medium, compressed air, etc. The installation of pipelines shall conform to relevant standards, and ensure the tight connection of pipelines without leakage. After the pipeline installation is completed, pressure test and cleaning are carried out to remove impurities and dirt in the pipeline.

Instrument installation: install various measuring and control instruments, such as temperature sensors, pressure sensors, flow sensors, etc., to ensure the correct installation position of the instruments, accurate wiring, and accurate measurement and display of various parameters during the operation of the equipment.

Debugging process

No-load debugging: after the equipment installation is completed, first carry out no-load debugging. Turn on the power supply, start the equipment, and check whether the rotating parts of motors, fans, pumps, etc. turn correctly, run smoothly, and have abnormal noise and vibration. At the same time, check whether the control systems and instruments work normally and whether the parameters are displayed accurately. Test all the actions of the equipment, such as the temperature rise of the spinning box, the speed adjustment of the metering pump, the start and stop of the winding mechanism, etc., to ensure that all the functions of the equipment can be realized normally.

Load debugging: after the no-load debugging is normal, carry out load debugging. Chemical fiber raw materials are added to the equipment, and various parameters, such as spinning temperature, pressure and rotating speed of metering pump, are set according to the process requirements, and simulated spinning experiments are carried out. During the test, closely observe the operation of the equipment, check whether the transportation, metering and spinning of raw materials are normal, and whether the fiber forming quality meets the requirements. According to the test results, the parameters of the equipment are adjusted and optimized until the equipment can stably produce chemical fiber products that meet the quality standards.

Performance test: after the load debugging is stable, test the performance of the equipment. Test the production capacity of the equipment, the physical properties of the fiber (such as strength, elongation, fineness, etc.), the operational stability of the equipment and other indicators, and evaluate whether the equipment meets the design requirements. If it is found that the performance index of the equipment does not meet the requirements, it is necessary to analyze the reasons, find out the problems, and make corresponding adjustments and improvements.

Safety inspection: always pay attention to the safety performance of equipment during equipment debugging. Check whether the protective devices of the equipment are complete and effective, such as emergency doors, emergency stop buttons and leakage protection devices. At the same time, the operation process of the equipment is evaluated to ensure that the equipment can ensure the safety of operators and equipment in normal operation and unexpected situations.

check before acceptance

Data acceptance: check whether the technical data such as installation and debugging records, operation manuals and maintenance manuals of the equipment are complete and accurate, and whether they meet the requirements of relevant standards and specifications.

Equipment acceptance: according to the equipment acceptance standard, comprehensively inspect and evaluate the appearance, installation quality, operation performance and product quality of the equipment. During the acceptance process, equipment suppliers, user representatives and relevant technical experts shall be invited to participate in the acceptance of the equipment.

Acceptance report: After the acceptance is completed, prepare the acceptance report, and record the acceptance process, results and existing problems in detail. For the qualified equipment, both parties sign the acceptance report, and the equipment is officially put into use; For the unqualified equipment, the rectification measures and time limit shall be specified, and the equipment supplier shall be responsible for rectification until the equipment passes the acceptance.
