Mechanical seals are critical components in a wide range of machinery and industrial equipment. These devices play a crucial role in ensuring the integrity and efficiency of machines such as pumps, compressors, motors and more.
In this article we will try to highlight the three main types of mechanical seals on the market.
Before we begin, however, it is essential to have the concept of a mechanical seal in mind. As detailed in this article, a mechanical seal is a device designed to prevent the escape of fluids from a rotating mechanical system. This is vital in a wide range of industrial applications, where even a small leak can cause serious operational and environmental problems.
There are basically three main types of mechanical seals: cartridge seals, component seals and air seals. Each of these seals has unique characteristics and specific applications, which make them essential for ensuring the integrity and functionality of various devices and machinery.
Let us analyse each type in detail.
A cartridge mechanical seal is a device designed to provide an airtight seal between two rotating surfaces or between another moving surface and a fixed surface within industrial machinery or mechanical equipment. It is called a 'cartridge' because all of its essential components, including the gland, the sleeve and the necessary hardware, are contained in a single self-sufficient unit, called a 'cartridge'. This configuration offers several advantages:
Mechanical component seals are devices used to seal two rotating or fixed surfaces in a mechanical system. This seal consists of two main parts: a separate rotating component and a fixed seat, both mounted in a gland or housing. Unlike cartridge mechanical seals, which are already pre-set and easier to install, component mechanical seals require a greater degree of experience for installation and maintenance.
These types of seals can be more complicated to handle, but offer greater flexibility and adaptability in some specific mechanical applications.
Mechanical air seals are devices designed to seal rotating shafts without coming into direct contact with them. These products are usually used in applications involving dry dust. Their principle of operation is based on the use of minimal quantities of air or inert gas, in order to prevent product leakage, reduce pollutant emissions and prevent contamination.
Mechanical air seals offer several advantages:
In conclusion, we focused on the three main types of mechanical seals, revealing their crucial role in ensuring the integrity and efficiency of a wide range of machinery and industrial equipment.
