 electronic actuator ADB225

An overview:

External type actuator, long service life, low price, although the work was slow, but can meet the vast majority of mining, transportation, business and civil life requirements, particularly suitable for Luqiao, infrastructure, sand, turbine with low quality, large impact load, and open operation, environment engineering, use and train, ship and so on for several days and nights, long-term operation of generating units. It sets the price of electronic speed governor fell 70%, and prolonging the service life of 20

50 times, the operation cost by 1 yuan / hour, down low to 1 points per hour. In Guangdong, Fu

The construction of the coastal areas and a plurality of railway bureau already extensive refitting. The installation, use two:

External type actuator is mounted on a mounting plate, the mounting plate is installed in the PT pump and diesel

Outside the machine between the two bolts. Execution among leading rod and PT pump throttle lever with three section rod connection, very convenient. The same and control method of plate.

Outside the company manufactured actuator, three sections of transmission rod is made of hard materials, light weight, fast response than imports; transmission structure adopts double ball bearing, a little shift, will not have the card wipe phenomenon, than the imported flexible.

External type actuator is mounted in a special iron plate, installing accelerator is installed between the PT pump and diesel engine plate

Two bolts. Execution of an output shaft of the pump and PT between the throttle shaft three section rod, the transmission link. Adjustable speed adjustable idle

1 from the PT pump out the built-in actuator, gambling change with O ring and M6 bolts and cover.

The throttle shaft 2 check PT pump positive no impact bending.

3.PT pump with built-in actuator, throttle lever is fixed on the outside the maximum position throttle (left), release the left side of the throttle lever two check head screw, a rotating shaft whether a card or loose. (pictured above)

The right to adjust the screw speed, about 650 to 750 rpm, locking. Adjust left screw to the high-speed, about 1700 to 1750 rpm, locking.

4 normally closed and normally open mode determined: external type actuator, the three section rod, pump shaft three.

Well, promote the actuator linkage, PT pump throttle lever to the left is normally closed (figure, right axis), the right is normally open (below, left axis, not recommended).

When parking, PT pump throttle lever position: normally closed on the right, often open on the left.

5 adjust the length of the intermediate lever, the throttle opening in 50% (70~80% load), the three section rod close to the square or rectangle, the two transmission rod and a shaft screw locking. Two rotating shafts should be strictly parallel, three transmission rod activities in the same plane

, rotate flexibly, without card of feeling.

Electric actuator 6 external connection to the original built-in actuator wire.

Normally open type

(not used)

The three section rod

The 7 controller: put in the original instrument box. Connection type (Modular), the side can be mounted on the instrument box, even good corresponding to each line.

The plug-in can be installed in situ, but the internal parameters to be modified, and external type actuator matching.

8 use normal, users are advised to do a cover shell, debris and dust pollution into the door.

9 normal use, pay attention to dust, regular cleaning, check fastening locking screws, bearings with a drop of high quality oil can.
