Washing machine system diagram front loading parts

Washing machine system diagram front loading parts: 1. Electronic board 2. Detergent dispenser 3. Tub suspension spring 4. Tub 5. Pressure switch 6. Detergent entry tube 7. Tube between solenoid and detergent dispenser 8. Solenoid 9. Water fill hose 10. Rear counterweight 11. Drum pulley 12. Bearings 13. Heating element with NTC 14. Drain hose 15. Motor pulley 16. Motor 17. Damper 18. Drain pump 19. Pressure chamber 20. Drain filter 21. Tube between tub and filter body 22. Eco-ball 23. Door safety interlock 24. Door 25. Door seal 26. Front counterweight In a washing machine, the dirt in the fibres is removed by a combination of mechanical and chemical actions. The solenoid valve ducts water through the detergent dispenser, where it collects the detergent and passes into the tub. The correct water level is controlled by one or more pressure switches. The fabrics loaded into the drum are maintained in cons...

Motor Speed Control triac schematic

Double-time-constant schematic diagram for Incandescent Light Dimming, Heat Control, and Motor Speed Control The schematic shown is a doubletime- constant circuit which has improved performance. This circuit uses an additional RC network to extend the phase angle so that the Triac can be triggered at small conduction angles. The additional RC network also minimizes any hysteresis effect.

Fluorescent Lamps electronic starter and ignition schematic

Standard conventional and circular fluorescent lamps with filaments can be ignited easily and much more quickly by using Thyristors instead of the mechanical starter switch, and solid state Thyristors are more reliable. Thyristors produce a pure solid state igniting circuit with no mechanical parts in the fluorescent lamp fixture. Also, because the lamp ignites much faster, the life of the fluorescent lamp can be increased since the filaments are activated for less time during the ignition. The Thyristor ignition eliminates any audible noise or flashing off and on which most mechanical starters possess. Figure shows a circuit for igniting a fluorescent lamp with 240 V line voltage input using Triac and DIAC networks. Figure illustrates a schematic using a SIDAC phase control network to ignite a 240 V ac fluorescent lamp. The one major change is that two K2400E devices in series are used to accomplis...

Soldering station with hot air

Based on features and cost, I selected the X-TRONIC 4000 rework station for my use. I ordered one and received it three days. If you've never used one of these stations before, may I suggest that you practice on a scrap PCB that has both large and small SMDs on it? I used an a old, discarded printer PCB. The soldering iron works very well and it's temperature controlled and is also ESD safe. As for the hot air nozzle, I removed small SMD devices with ease. I applied some rosin flux to the leads of a 100-pin IC and then I slowly moved the hot air nozzle (temp set to 300 degrees C.) around the it to preheat the IC's soldered leads. After about 30 seconds, I increased the hot air temperature to about 400 degrees C and continued moving around the IC, melting the solder. Using the "IC popper" gadget, I gently lifted the IC away from the pcb. The magnifying lens/lamp helped my old eyes to see the more clearly. "X-TRONIC" MODEL #4040 - 4000 SE...
