The rubber diaphragm is a flexible membrane that divides and seals the two connected chambers. It protects the pressure sensors from the fluid in which the pressure is measured. This thin rubber diaphragm can last in a high-pressure environment while maintaining responsiveness in minor pressure discrepancies. Typically you will see this diaphragm that uses valves, compressors/pumps, hydro/liquid accumulators, regulators, and any industrial machinery part of their day-to-day operations. There are many options for creating this rubber diaphragm, whether for individual or general purposes, but we use elastomer to maintain its flexibility to fulfill its job. Every application is different, so basically, the rubber diaphragm is not created equally, and we made them according to its implementation and specification to ensure quality and effectiveness. It can be made in a wide range of compound materials, depending on what needs to be sealed. One of the most critical components of a fuel pump is the diaphragm. Our diaphragm has a high chemical and corrosion resistance, making it the ideal material for this application. It must withstand the high temperatures and pressures in the fuel pump.
RK Rubber Philippines has extensive experience in creating rubber diaphragms for various applications. We offer a wide range of compounds like EPDM, Nitrile, Styrene, Silicone, Polymer, and Fluorocarbon to meet the industry’s specifications.
We can assist our clients with design reviews for manufacturability and feasibility, compound selection or development, prototyping, support for design, and application testing.
Manufacturing Process of Diaphragm
The manufacturing process of a rubber diaphragm begins with selecting the correct type of rubber. The rubber is then cut into the desired shape and size, trimming the edges. Next, the rubber is placed in a mold and heated until it softens. The mold is then removed, and the rubber is cut into the final shape. In some cases, the mold may be reused for several diaphragms. Rubber diaphragm shapes are limited only by imagination, and many different designs are available.
Advantage and Disadvantage
They offer some advantages and disadvantages that should be considered when selecting a diaphragm type. Benefits of rubber diaphragms include:
- Easy to install
Some disadvantages of diaphragms include
- Susceptibility to heat
- Ozone degradation
- Limited temperature range
Features of Rubber Diaphragm
- Tear and wear resistance
- Minimal to n friction and lubrication required
- Durable in terms of handling high pressures
- No friction
- Plain looking and flexible
- High chemical resistance
- Perfect fit for effective sealing
In conclusion, the rubber diaphragm is essential to the pressure sensor. It separates and seals the two connected chambers while protecting the pressure sensors from the fluid in which the pressure is measured. Without a rubber diaphragm, these sensors would not be able to function correctly.
