AS-C5600DP Double Cartridge Mechanical Seal

AS-5600DP seal，together with AS-C5600D seal， is the first truly universal Dual Cartridge O-ring Seal. Since the 5600 Series parts are interchangeable, you can apply one seal family throughout your plant. This gives you the ability to apply the seals in more applications with less inventory, which means your maintenance is simplified, downtime is cut down, plant operating efficiency is increased and costs are reduced. Designs available conform to API 682, Category 1.

Features:
Includes a rubber O-ring as the secondary sealing unit
Primary ring and mating ring reverse balance designs allow for ID or OD pressurization, which allows the double seal to operate as a low-pressure barrier tandem seal or a high-pressure barrier double seal.
OD pressurization of the outboard seal avoids subjecting components to high tensile stresses and achieves better cooling. On vertical installations, it allows venting of entrapped air.
Non-clogging wave spring outside the product.
Optimized primary ring design for greater reliability.
Tangential outlet and inlet pipe connections below 3.000"/75mm.

Mechanical seal end face temperature test technologies of non-contact type
In recent years, great progress has been made in the research on temperature characteristics of friction end faces of mechanical seals. At present, the end face temperature test technologies can be divided into two categories: contact type and non-contact type.

Mechanical seal end face temperature test technologies of non-contact type mainly includes infrared thermometry and acoustic thermometry.

Infrared thermometry is a method of measuring the temperature using infrared spectroscopy. The method can realize continuous and real-time measurement without disturbing the measured temperature field. Infrared temperature measurement can easily measure the surface temperature of moving objects, and can solve the problem of surface temperature measurement of high-speed rotating parts.

However, due to many factors such as surface emissivity，surrounding environment and so on, its temperature measurement accuracy is usually lower than that of thermocouples. In addition, thermal imaging cameras are expensive and it is difficult to popularize them.

The basic principle of the acoustic wave detection method is to collect the acoustic waves generated by the friction of the sealing faces of the mechanical seals and process them accordingly to obtain contact information of the sealing faces.Acoustic waves have advantages such as non-invasiveness and faster response time. Over the past few decades, acoustic thermometry has gradually evolved into a new temperature measurement technology in environments where conventional means such as thermocouples cannot meet the requirements. It is a very meaningful direction in studies of the end face temperature measurements of mechanical seals in the future. Besides，how to distinguish the source of acoustic information is an important task in the future research on acoustic thermometry.
