Field Requirements for Floating Seals Application

Preventive measures against leakage during the trial operation of floating seals:

Check if the air filter is clogged, causing the housing to over-pressure.

(2) Check the compression of the "O" ring or the "A" value (size) for suitability.

(3) Inspect the working medium for granular substances that may enter the friction components during operation, causing wear to the DO0900 tunneling machine floating oil seal and the sealing ring.

(4) Verify if there are any errors in design selection, such as if the sealing face is too low or if the sealing material has excessive shrinkage.

This phenomenon often occurs during the trial operation, and is usually eliminated by appropriately adjusting the "A" value, or may require disassembly and replacement of the seal.

2. Measures to prevent flashing due to the seal during operation, which may cause wear and bonding of the sealing face:

(1) Verify sealed product conditions based on original criteria.

(2) Check if the machine's lubricant level is sufficient.

GNL Floating SealInstallation Instructions

Thoroughly clean the cavity parts, removing any residue, ensuring all edges of the grooves are smooth.

Only the original packaging of the floating oil seal can be opened before installation to remove the sealing part.

Check the position of the O-ring, ensuring it is not distorted. Place half of the sealing ring into the cavity entrance and evenly press it into the cavity. Use anhydrous ethanol to moisten the grooves and rubber rings for easier installation. DO0900 Excavator Floating Oil Seal model. Absolutely prohibited to use lubricating oil or grease for assistance in installation.

Check that the outer surface and sealing face of the groove after installation are parallel; a significant deviation is 1MM. The O-ring must have no undulations or protrusions within the groove.

Why can't a floating oil seal be installed with oil?

Some users of floating oil seals improperly apply a layer of oil to the O-ring during installation for ease of assembly, and even worse, some even coat the cavity of the floating seal seat with grease. This is entirely incorrect.

Its safety hazard is:

1. Floating oil seals are rotating, but both rings are stationary; DO0900 Tunneling Machine Floating Oil Seal Manufacturer, if oil is present, it's prone to distortion and sliding.

2. NBR rubber rings have good oil resistance, but it's within a certain range. The installation gap for the DO0900 tunneling machine's floating oil seal accelerates the aging of the rubber ring after lubrication. Floating seal ring manufacturer.

Proper installation should be: Clean the floating oil seal ring, iron ring, and conical surface of the seat cavity with alcohol during installation, leaving no oil residue.

After proper use, the anti-slip performance, anti-aging properties, and service life will be significantly enhanced.
