5464-444 Woodward Ship Spare Parts

The 5464-444 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 5464-444
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:
- 5464-444 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.

The fire linkage controller can set a delay for specific control output functions, with a maximum delay time of no more than 10 minutes. During the delay period,

the control output can be manually inserted and immediately activated.

7) The fire linkage controller with control function for the gas fire extinguishing system in the pipeline network can display the manual and automatic working status

of the gas fire extinguishing system in the pipeline network; Corresponding fire sound and light alarm control signals are issued during the alarm and spraying stages of the gas fire extinguishing system.

8) A fire linkage controller with information recording function can record at least 999 relevant information and maintain it for 14 days after the fire linkage controller is powered off.

9) The fire linkage controller has a fault alarm function. When there is a fault signal in the external connection and controller power supply, it can emit sound and light fault signals

within 100 seconds. Any faulty part does not affect the normal operation of non faulty parts.

10) The fire linkage controller has a self checking function to check the functionality of the machine.

11) The power supply of the fire linkage controller includes a main power supply and a backup power supply conversion device. When the main power supply is cut off,

it can automatically switch to the backup power supply; When the main power supply is restored, it can automatically switch to the main power supply.

2. Performance

1) Capacity:

The capacity of the fire linkage controller refers to the sum of the number of addressing devices that can be connected to the fire linkage controller bus and the number

of dedicated control circuits. The number of addressing devices that can be connected to the fire linkage controller bus is represented by “M”. Generally, two related parameters are given,

one is the number of bus circuits that the fire linkage controller has, represented by “F”; The other is the number of addressing devices in each bus loop, represented by “N”. The bus capacity is

equal to the number of loops multiplied by the number of addressing devices in each loop, that is, M=F × N.
