PRODUCT FEATURES
PRODUCT DETAILS
W (z) T series oil-free electric rotation microcomputer governor is a safe and reliable microcomputer governor composed of imported industrial controller PLC / PCC as the control core, servo oil-free electric rotation as the electro-hydraulic conversion link and mechanical hydraulic system as the actuator. It is applicable to the regulation and control of large and medium-sized water turbine generator units.
Electrical control system:
◆ the microcomputer adopts imported PLC or PCC, and dual PLC or PCC can be selected
◆ imported stepping motor or AC servo motor and driver can be selected
◆ oil free electric rotation adopts unique absolute positioning control, with high precision and fast response
◆ residual voltage frequency measurement and gear disk frequency measurement are used for frequency measurement, which are primary / standby to each other
◆ absolute encoder, linear displacement sensor, potentiometer, etc. can be selected for electrical feedback
◆ friendly man-machine interface
Mechanical hydraulic system:
◆ the hydraulic system adopts integrated block design and direct connection structure, without exposed pipe and lever
◆ the valve body of the main pressure distribution valve adopts the structure of fully forged steel parts, with small volume, high strength and large flow area
◆ it has a pure mechanical manual operation mechanism
◆ the electro-hydraulic converter adopts a patented product with independent intellectual property rights. Patent number: ZL 2017 2 0632025.2. It automatically resets after power failure, has no fuel consumption and jam, is less affected by temperature, and has strong oil resistance
◆ double oil filter
◆ optional double oil-free electric rotation, switching without disturbance
◆ oil pressure grade: 2.5MPa, 4.0Mpa, 6.3MPa
◆ diameter of main distribution valve: ф 60、 ф 80、 ф 100、 ф 150、 ф 200、 ф two hundred and fifty
