1720-713 Woodward Ship Spare Parts

The 1720-713 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 1720-713
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 1720-713 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

What is a logical drive

A logical drive is a virtual drive in an array that can occupy more than one physical disk.

Logical drives divide the array or disks across the array into contiguous storage spaces, which are distributed across all disks in the array.

The NetRAID controller can set up to 8 logical drives of different capacity sizes, and at least one logical drive must be set up in each array.

Input/output operations can only run when the logical drive is online.

There are three types of hard disk partitions: primary disk partition, extended disk partition, and logical partition.

A hard drive can have one primary partition, one extended partition, or only one primary partition without an extended partition. Logical partitioning can be multiple.

The primary partition is the boot partition of the hard disk, which is independent and the first partition of the hard disk. If divided normally, it is the C drive.
After dividing the main partition, the remaining part can be divided into extended partitions. Generally, the remaining part can be fully

divided into extended partitions or not fully divided, and the remaining part will be wasted.

But extended partitions cannot be directly used, they are used in a logical partition manner, so extended partitions can be divided into several logical partitions.

Their relationship is an inclusive relationship, and all logical partitions are part of the extended partition.
