The hole hydraulic console for Jiangsu Changli hydraulic cylinder Co. Ltd. is Marlin company's own design and debugging, the outsourcing console, the end user is Chinese Petroleum Pipeline Bureau dimensional repair branch.

        The system realizes the driving control of the cutting motor and the feed motor during the opening process, and is the renovation project of the original hydraulic station. The system uses two encoders to measure the rotational speed separately, and sends the read signals to the MCU and trigger chip respectively. The trigger is used to provide the signal to determine the direction of rotation to the microcontroller, and to calculate the positive and negative speed by single chip microcomputer 

Holes drilling hydraulic control desk is made for Jiangsu Changli cylinder co.,Ltd., which is design and commission by Marlin Engineered Technologies(Shanghai) outsourcing process control desk,the end customer is China petro natural gas piping system maintenance Co.,Ltd.

System realized cut motor and feed motor driven and control, which is original hydraulic station upgrade system.System detects motor speed from two encoders,pass the input signal to single chip microcomputer and trigger chip,trigger generates rotation direction signal to single chip microcomputer(abb. SCM),then SCM calculates clock wise and counter clock wise running speed.
