1Overview

1.1Product Features

During the processing and molding of rubber and plastic materials, their flowability is almost always involved. For example, in processes such as extrusion, injection molding, blown film, and rolling, the flow behavior of materials is crucial. The fluidity of materials not only affects processing behavior, but also affects the mechanical properties of the final product. For example, molecular orientation has a significant impact on the mechanical properties of molded products, films, and fibers. The type and degree of molecular orientation are mainly determined by the characteristics of the flow field and the flow behavior of the material during the processing.

3. Installation technicians should be familiar with the drawings, master the construction standards and specifications, conduct equipment technical disclosure, and enable operators to operate according to the process requirements.

4. Adhere to the "three inspections and three pre controls", namely self inspection, mutual inspection, and special inspection. Quality is mainly based on pre control, and dynamic tracking inspections are carried out during program construction. When the previous program is completed, static inspections of program quality are conducted, and then the next process is carried out to strictly pre control quality factors.

1Ensure safety organizational measures

1) Debugging and installation personnel should strictly comply with the safety and fire prevention regulations of the demand unit, and those who violate them will be punished.

2) During the debugging and testing period, if there is hot work, it is necessary to apply for a hot work notice from the relevant department of the construction unit and obtain approval before hot work can be carried out.

3) All debugging and installation personnel are not allowed to smoke in flammable and explosive areas.

2. Technical measures to ensure safety

1) Electricity safety measures

a. Temporary power circuits must be installed on site using insulated flexible cables and installed according to regulations. Random placement and connection are not allowed. Temporary power lines should be installed at high altitudes as much as possible, and protective measures should be taken for corridors and turns. Markings should be placed underground. b. When there is a temporary power outage on site, all power sources should be immediately cut off.

c. Various specialized electrical equipment on site should be used by dedicated personnel.

3. Fire safety measures

a. To prevent fires and provide serious training to equip them with certain firefighting knowledge and skills, to prevent or reduce the occurrence of fires, and effectively control the spread of fire.

4、 Debugging and acceptance plan

1. Equipment debugging

1.1 Inspection before Debugging

Before debugging, organize relevant personnel to familiarize themselves with the drawings, carry out technical disclosure work, and ensure the safety of equipment and personnel during the debugging process.

After completing the wiring work between the computer and various devices, first check and verify the internal wiring and input/Output wiring. Before powering on the local control unit, perform insulation inspection on the cabinet and cables. Confirm correctness and proceed with power on for static debugging of the computer.

1.2 Static debugging

Perform the following checks through computer-controlled static debugging:

a. Whether there is a short circuit phenomenon;

b. Whether the signal display and alarm display on the simulation screen are correct;

c. Are all output relays operating normally;

d. Are all feedback signals functioning properly;

e. Whether all operation buttons and switches are operated correctly;

f. Does the program design comply with the required process control flow;

g. Whether the signal and alarm functions are normal;

h. Whether the simulation tests of system processes, such as simulating faults and accident shutdown processes, are normal;

i. Is the system linkage debugging running normally;

j. And verify the correctness of each process, preliminarily determine the optimal coordination time for each step;

1.3 No load and load debugging

The automatic control power on commissioning of the equipment system shall be carried out according to the procedure of commissioning the control circuit first, then the main circuit, and the no-load operation first, then the load operation.

Power on debugging of control circuits is to check whether the wiring of electrical control and distribution equipment is correct. During the experiment, the main circuit does not supply power, only the control power is turned on, and then the corresponding buttons or other main electrical appliances are sequentially turned on according to the actual working program. Each operation checks whether each corresponding electrical component has acted according to the prescribed program(such as whether the corresponding signal light is on, whether the contactor is closed or separated, whether the action sequence and delay situation meet the design requirements, and whether there are other abnormal situations, etc.). When necessary, perform manual simulation of fault signals for inspection, such as pushing the contactor core to check if the interlock is effective, simulating the action of limit switches to check if the protection is reliable, pressing the emergency stop button or connecting the power supply of the shunt release coil to check the emergency stop and fault disconnection functions, etc. After several power on tests, all electrical components operated normally and the computer's fault diagnosis function was functioning properly; The fault protection function of the local station is reliable; The simulation tests of the system process, including the simulation of faults, accident shutdown processes, etc., are all normal; Prove that the wiring of the control part is correct and can be used for no-load testing.

Before powering on the main circuit, confirm again the correctness of the main circuit wiring and conductor selection; During the trial operation, inspect the electrical control and distribution equipment, including the inspection content; When the system is conducting linked load debugging and running, determine the optimal coordination time for each step;

2. Online debugging;

(4) Perform full load linkage debugging

Before powering on the main circuit, confirm the correctness of the main circuit wiring and conductor selection again, and check whether the short-circuit and overload protection devices meet the requirements. After no-load testing, the computer program can control according to the required process control flow, and whether all output relay actions are normal; Are all feedback signals functioning properly; Whether the signal and alarm functions are normal, and whether the signal display and alarm display on the analog screen are correct; The no-load current of the motor is normal and can be tested for load operation.

During the trial operation, inspect the electronic control and distribution equipment, including checking the data of each indicator instrument and whether each electrical component is working properly, whether the conductor contact points are loose, overheating, and other abnormalities. After inspection, there were no abnormal phenomena.

When the system performs linked load debugging and operation, determine the optimal coordination time for each step, and further adjust and improve the application software.
