Part 1 of a 3-part series on Compressors

Introduction

When dealing with various applications, the use of a disk check valve is common for many systems. However, it's essential to recognize that in certain situations, merely having a discharge check valve may not suffice. Many individuals mistakenly believe that a discharge check valve is a fully sealed component; in reality, it often operates as a floating valve. This distinction becomes crucial, especially when attempting to pump down a system.

Understanding the specific type of compressor you are working with is vital. Different compressors may require different configurations to achieve optimal performance. For example, if you encounter issues while working with a system, you might find that there's the need to add an extra discharge check valve. This practice isn't uncommon, but it can lead to confusion if you're not well-versed in the requirements of the compressor in question.

Consulting the manufacturer’s manual is paramount. Manuals from manufacturers such as Tecumseh, LG, Bitzer, and Danfoss provide critical insights that can clarify the necessary components for specific applications. By referring to these manuals, you can avoid frustrations and unnecessary troubleshooting efforts commonly associated with a lack of understanding regarding the compressor type you’re dealing with.

In summary, comprehension of the specific compressor you're charging or working on greatly reduces the chance of running into problems. It's imperative for technicians and engineers to familiarize themselves with these details, as it can save valuable time and resources in the long run.

FAQ

1. Why may I need an extra discharge check valve even if I have a disk check valve?
You may need an extra discharge check valve because a discharge check valve is usually not fully sealed; it operates as a floating valve. This can pose challenges when pumping down a system.

2. Where can I find specific information regarding the compressor I'm working on?
Manufacturer manuals from companies like Tecumseh, LG, Bitzer, and Danfoss offer valuable insights about the compressor. Consulting these manuals can provide clarity on necessary components.

3. What are the potential problems of not understanding the compressor type?
A lack of understanding can lead to confusion, unnecessary troubleshooting, and potential issues with system performance. Familiarizing yourself with the specific requirements of the compressor can save you time and resources.

4. How does a floating valve differ from a fully sealed valve?
A floating valve, like many discharge check valves, is not fully sealed, which means it can lead to a backflow or leakage under certain conditions, unlike a fully sealed valve that would prevent any backflow entirely.

5. What should technicians do when they encounter problems with a compressor system?
Technicians should first refer to the manufacturer's manuals for troubleshooting guidance. Understanding the specifications and requirements of the compressor tools is essential for effective problem-solving.
