Water seals utilize V-shaped rubber suitable for rotary shafts to prevent contaminants from entering, providing dust and water resistance. So, what are the different types of water seals available?

Types of Water Seals:

V-ring seals come in various standard cross-sections to meet different spatial and application requirements. Some cross-sections increase with shaft size, while other types maintain the same section throughout the diameter range.

Structural Design of Water Seals:

The design principles for water seals are as follows:

1. Select the appropriate structure and material based on working conditions.

2. Control the thickness and angle of the lip during structural design. Excessive lip thickness can exacerbate wear, while too thin may compromise sealing effectiveness. The lip angle also impacts the sealing effect. Additionally, control the thickness of the waist and the strength of the main body.

3. Control the amount of stretch during water seal installation based on the tensile properties of different materials.

V-shaped Water Seals:

GVA, GVAX, GVL, and GVE types belong to V-shaped water seals. Taking the most commonly used GVA type as an example, let's explore the structure of water seals. GVL, GVAX, and GVE have fixed cross-sections suitable for medium to large shaft diameters. The GVS type water seal has a thicker support matrix, offering a stable structure.

R-shaped Water Seals are generally used for large shaft diameters with fixed cross-sections. To facilitate installation and save costs, a structure with an opening and clamping belt is chosen.

Therefore, based on the primary applications of water seals such as various mechanical lubricants, water, dust, oxide scale, water in the neck of rolling mill rolls, etc., suitable types of external skeleton oil seals can be selected by choosing the appropriate structure and material.
