Introduction
In this article, Faraz Shiraz Fan, an expert in industrial balancing services in Iran, will comprehensively review the process of ship propeller balancing, its advantages, types of methods, and its specialized points.
What is propeller balance and why is it important?
Balance of the ship's propeller means creating a weight and geometric balance between the blades and different parts of the propeller so that pressure and force are evenly distributed when rotating in the water.
The reasons for the importance of ship propeller balance:
Prevention of dangerous vibrations in the power transmission system
Decreasing depreciation of bearings, shaft and motor
Increasing motor efficiency and reducing fuel consumption
Prevention of high noise emissions in the water environment (important for research and military ships)
Increasing the safety and longevity of marine equipment
Problems of ship propeller imbalance
1. Excessive vibration
One of the first signs of incorrect balance is unusual vibration and noise from the propulsion part of the ship.
2. Uneven pressure on bearings
Asymmetrical weight causes excessive stress on the bearings and shaft.
3. Corrosion and cracks on the blades
Incoherent dynamic stresses over time cause premature failure or corrosion of blades.
Types of propeller balance methods
1. Static balance
In this method, the propeller is checked in a fixed state and balance is created by adding or removing weight.
2. Dynamic balance
In this method, the propeller is balanced in the simulated rotation state, which has higher accuracy.
3. On-Site Balancing
For ships whose propellers are difficult to remove, balancing is done on site with mobile equipment.
Procedures for balancing the propeller of the ship in Faraz Shiraz Fan
In Faraz Shiraz Fan, ship propeller balance is done using the most advanced industrial balance devices and expert skills. The general steps include:
- Preliminary inspection and vibration analysis
- Cleaning and preparation of the impeller
- Measurement of unbalance with the testing device
- Applying weight corrections with micron accuracy
- Final test and performance verification
Advantages of using the services of Faraz Shiraz Fan
Expert team with work experience in industrial and marine projects
Balance equipment with ISO 1940 standard
Possibility of balance at the ship location or central workshop
Reducing future repair costs and increasing propeller life
Key tips to increase the lifespan of a ship's propeller
- Annual inspection and preventive maintenance planning
- Cleaning marine sediments from the propellers
- Avoid hard objects hitting the propeller
- Balance after every repair or welding
Why balance ship propeller is an economic necessity?
The imbalance causes the ship's engine to use more power to overcome the resistance. This directly increases fuel consumption and running costs. According to estimates, the correct balance can reduce fuel consumption by up to 15%.
