A. Wet alarm system

1. System summary: Overview of Wet Alarm System

2. Equipment cognition: set up the best perspective, equipment det--ls (display the introduction or parameter of the device), practice (built -in 6 selection questions, there are prompts for correctness and errors), schematic diagrams (can be entered from the schematic diagram Go to the device). The equipment includes: nozzle, water flow indicator, signal butterfly valve, exhaust valve, fire alarm control, executive pressure gauge, high water tank, Weia control cabinet, stabilization tank, flow switch, end -end water testing device, dr--nage facility, water pump combinations, water pump combination Instruments, hydraulic bells, latencys, wet alarms, butterfly valves, stop valves, fire pumps, safe stabilization valves, fire pools.

In recent years, with the widespread application of CNC technology, the school has p--d more and more attention to practical and skillful talents that cultivate jobs in production and technical services. Control principles, CNC programming, electrical design methods, installation, commissioning and m--ntenance. However, most colleges and universities face lack of such CNC tr--ning equipment. To this end, the company has developed the internship device of electrical control and m--ntenance of CNC milling machines.

  This tr--ning device is a CNC milling machine conditioning and m--ntenance assessment tr--ning equipment developed for vocational colleges, technical schools, and vocational education and tr--ning institutions. The work appr--sal requirements of the workers are required to study the electrical control and mechanical transmission of CNC machine tools. It is specially designed for tr--ning teaching activities. Control, low -voltage electrical control, mechanical transmission and other technologies have strengthened the students' comprehensive capabilities such as the installation, wiring, debugging, fault diagnosis and m--ntenance of CNC machine tools. It is suitable for teaching and tr--ning of mechanical and electrical related majors. Evaluation and identification of work. At the same time, it also provides necessary conditions for the secondary development of the CNC milling machine system.

1. Product structure and composition

1. The system consists of machine tools, CNC milling machines, etc.

2. The machine tool tr--ning cabinet adopts the iron spraying structure of iron sub -light -dense lines. The upper part of the front is monitoring the original device in the intranet voltage, current, and status indicator light. The middle part is the machine tool electrical cabinet. The electrical installation board in the electrical cabinet is equipped with inverter, servo drive, AC contactor, relay, fuse seats, circuit breakers, switching power supply, wiring terminal row and wiring slot, smart fault module, etc.; There are transformers and ground terminals.

3. The front and side of the machine tool are equipped with a two -way open -open door with a two -way lock, which is convenient, safe, and dust -proof. There are two p--rs of door on the back, 4,000 -way wheels are installed at the bottom, and the brake device is equipped to facilitate movement and fixation.

4. The system adopts three -phase four -line AC380V AC power supply, and has a leakage protector, indicator indicator and fuse, etc. It has overload protection, short -circuit protection and leakage protection device. It automatically moves when the voltage is abnormal or short -circuited to protect the body and the body and the person. Equipment is safe.

5. CNC systems use the FANUC 0I-MF CNC system.

6. The X, Y, and Z axes are driven by the AC servo motor. The movement direction has functions such as positive and negative limits, reference points, etc. The m--n axis is driven by three -phase and different step motors.

7. The m--n axis, bed body, tr--ler, etc. use casting structures. The casting is timed processing, surface processing and shovel scraping process to ensure stable accuracy of machine tools.

8. X, Y, and Z shaft in the transmission system are composed of the drill screw nut, bearing, bearing support, and motor support. The assembly and adjustment of the roller screw is tr--ned.

9. Machinery tr--ning Safety Education Virtual Simulation Software: This software is developed based on Unity3D. The software uses a three -dimensional roaming form. It can control the movement through the keyboard. Basic assessment of the protection design. During the experiment, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius. The experimental process is accompanied by a three -dimensional robot dialog box reminder.
