Oval Type Suction Bell Mouth

An oval type suction bell mouth is a type of mouth installed on a ship to suck in water and air. The oval type suction bell mouth has a large opening area and can provide a relatively large liquid intake. The flow characteristics of the oval type suction bell mouth are better, the flow of liquid in the elliptical pipe is relatively smooth, and its structural stability is strong.

Overview

How to choose a Marine suction bell mouth suitable for different liquid properties

1. Liquid properties: Understand the nature of the liquid that needs to be inhaled, such as fuel, water, sewage, etc. Different liquids may have different characteristics such as corrosion, density and viscosity.

2. Material compatibility: According to the nature of the liquid, choose the right material to make the suction bell mouth. Common materials include stainless steel, copper, aluminum alloy and so on. Ensure that the material of the suction bell mouth is compatible with the liquid in contact to prevent corrosion and leakage.

3. Sealing performance: The nature of the liquid may have requirements for sealing performance. For example, for flammable or toxic liquids, it is necessary to ensure that the suction bell mouth has a good seal to prevent leaks and safety incidents.

4. Size and flow: According to the design of the ship and the flow requirements of the liquid, choose the appropriate size of the suction bell mouth. Make sure that the diameter of the inlet meets the required flow rate while avoiding too large or too small a size.

5. Installation method: Consider the installation method of the suction bell mouth, such as flange connection, thread connection or other connection methods, to ensure that the installation is firm and reliable.

6. Corrosion resistance: If the liquid is corrosive, it is necessary to choose an suction bell mouth with corrosion resistance. For example, for more corrosive liquids such as seawater, special stainless steel or coating materials can be selected.

7. Regulations and standards: Comply with relevant ship regulations and standards to ensure that the selected suction bell mouth meets the requirements. These regulations and standards usually relate to safety, environmental protection and performance.
