- Good morning students. Theme of our program is: «Assembling, repair and technical service set-regulate apparatus». Theme our lesson is: «Assembling chains operate set асинхронный electric engine electromagnets actuator». Form habits by fulfilment electro assembling works, chains manage electromagnets actuator, develop creative approach by fulfilment works, and bring up punctual attitude by equipments and instruments.
- Let`s repeat questions theoretical материал
1. Purpose electromagnet actuator
2. Purpose thermal relay
3. Purpose push-buttons of manage
4. Mark electromagnet actuator on the scheme
5. Mark push-buttons of manage on the scheme
6. Mark thermal relay on the scheme
7. Brand of electro assembling wire
- Please, show us how to take off insulation and cleaning veins of wire.
- All metal-cutting machine-tools, lifting-cranes, conveyors, pumps, компрессоры, set in motion of electro drive, which control electromagnet actuator.
- Present work will be manage at this stands. This is working electromagnet stand. Electric scheme.
- Now, I`d like to tell you about consistent fulfilment operation on instruction-technological map:
1. Preparation wire by assembling
2. Connection net-wire by push-button “Stop” and winding actuator
3. Connection blockading contacts by contacts push-button
4. Connection push-button “Start up”
5. Combination contact actuator with winding actuator
6. Check up capacity for work of scheme
- Well, I show you ways fulfilment of work and organization working place:
1. Connection net-wire by thermal relay and winding actuator
2. Unit push-button “Stop” and actuator
3. Unit push-button “пуск” and actuator
4. Check up capacity for work of scheme
5. Advanced methods electro assembling works
Self-control in time fulfilment of work:
Work fulfil in conformity with instruction-technological map, with check up every element.
Rules of technology safety in fulfil of works:
Punctually treatment with electro assembling knife and instrument. Switching on educational stand only with permission chief of the room.
Typical mistakes: Mistakes into unit push-buttons and actuator
Kind of spoilage: Breakage contacts of actuator and push-buttons of fulfilment.
Please repeat methods fulfilment of works and technology safety.
Rate of the time at fulfilment of work 4 hours.
Estimation “5” - if you make capacity for working scheme and qualitative assembling
Estimation “4” - if you make capacity for working scheme, but not qualitative assembling
Estimation “3” - if you make only 1 mistake in assembling on scheme
Our lesson is over. Do you have any questions? Well, I`m very glad your work.
