Actuator related technical knowledge:
I. principle:
The coil is connected with the direct current, and the oblique end of the armature (outer end) generates torque to balance with the spring force, and drives the rotor oil hole to rotate,
Adjust the amount of oil has reached the purpose of controlling speed. Change the speed of the - engine.
Two, structure:
Actuator is a high-precision device, the key to accuracy, in the relative movement of the friction surface gap, requiring rotation is very flexible, very small gap,
Corrosion resistance, smooth finish, high hardness and long service life.
Three, varieties:
Oil supply mode:
Divided into normally open and normally closed two categories, open parking often open hole, normally closed throttle switch.
Unit power:
Is divided into small flow 200 ~ 300KW, medium flow 400 ~ 600KW, large flow 800KW or more use, flow size by oil hole
Size is determined, and the executor has the same overall structure.
Four, specifications:
Voltage: 24V, coil resistance 22, 7.2 + 0.4 ohms, inductance: 120 + 20 milli, reaction time 15 milliseconds.
Operating temperature: 38, 7.7, 94, 9.6, maximum operating temperature 125, 10.6.
Five, normal work: when opening the power supply: there are agile, crisp, small sound, often open type 1 ring, usually closed type 2 ring. If the actuator is hairpin, the sound is hoarse or not loud.
Six, matters needing attention:
The fuel must be cleaned and the oil filter must be replaced regularly.
Loading and unloading must be made according to the prescribed procedures and the order of the screw position. Replace the new O ring each time handling.
The normally open or normally closed type actuator must be matched with the same type of control board, otherwise the starter can not speed up or drive to the high speed.
This has nothing to do with the panel and the big bottom.
Size: 8 (L) *8 (W) *9.5 (H) cm
