Abstract

DC60 (27/09/47) When SW starter 3 is depressed, the single shot multivibrator 15 will open and the pulse chimney. A pulse is sent to the self-holding circuit 16, which continues in self-holding mode. and release H-level output continuously until being re-established This will cause transistor 17 to open and actuate the piston moving relay down R1. When the piston reaches the lower limit of its displacement, the lower LS 4 is opened causing the self-locking circuit 21 to generate an H level signal based on the multivibrator output. Single-shot router 18 The H level signal from the self-locking circuit 21 is delayed by the delay circuit 22 and the transistor 23 is turned on as a result. The piston-up relay R2 is triggered because of the function of the single-shot multivibrator circuit 15, the piston will not start again. When SW starter 3 is continuously pressed low, the delay circuit 22 will provide a service life of the switch mechanism. The flap thrust is also longer where a combination of another delay circuit 19 and a logical multiplication circuit 24 is provided to prevent any faults caused by the collision of the lower LS 4 when SW starter 3 is depressed, single shot multivibrator 15 opens and pulses chimney. A pulse is sent to the self-retaining circuit16. which will stay in self-holding mode and release H-level output continuously until being re-established This will cause transistor 17 to open and actuate the piston moving relay down R1. When the piston reaches the lower limit of its displacement, the lower LS 4 is opened causing the self-locking circuit 21 to generate an H level signal based on the multivibrator output. Single-shot router 18 The H level signal from the self-locking circuit 21 is delayed by the delay circuit 22 and the transistor 23 is turned on as a result. The piston-up relay R2 is triggered because of the function of the single-shot multivibrator circuit 15, the piston will not start again. When SW starter 3 is continuously pressed low, the delay circuit 22 will provide a service life of the switch mechanism. The thimble of the flap, the longer direction also the combination of another delay circuit 19 and the logic multiplier circuit 24 is provided to prevent any faults caused by the collision of the lower LS 4.

1.Hydraulic driven instrument control device to drive up and down the ball. Pumped in the cylinder by the use of hydraulic power And drill a hole in the workpiece with a bore attached to the lower end of the piston, which at least consists of Lower limit measuring path To measure the lower limit of piston movement Valve control path that responds to the measuring signal from the lower limit sensing path. To change the hydraulic oil flow acting on the piston from downward motion to upward motion and trajectory generating a pause time. To provide a pause period according to the amount of time Predefined switching between descending and descending movements. Where the way of control Flap, including first and second solenoids And the first and second push rods that are driven by First and second solenoids respectively. And was located on both sides of the valve So that the flow Of hydraulic oil acting on the piston Can be switched from downward motion As an upward movement The push lever is driven to switch the valve between the first and second positions.
