The PLAN32 scheme involves injecting an external flush liquid into the mechanical seal, with the flush liquid being transported along with the pumped liquid. This solution is particularly suitable for conditions with extremely high particulate matter, common applications in pulp pumps, and flushing solutions for high-temperature heavy oil pumps.

Detailed Description:In the PLAN32 scheme, an external clean source is used to flush the mechanical seal, and the flush liquid travels along with the pumped liquid. It is crucial to carefully choose the source of the flush liquid to eliminate issues such as liquid evaporation or contamination by the pumped liquid.

Reasons for Adoption:This scheme is adopted to achieve the following objectives:

Heat Removal from the Seal Chamber:The external flush liquid helps remove heat from the seal chamber, contributing to the cooling of the mechanical seal.

Removal of Process Fluid or Solids from the Seal Chamber:The flush liquid aids in eliminating process fluids or solids from the seal chamber, enhancing the pressure within the seal chamber and broadening the fluid vaporization critical range.

Application Scenarios:The PLAN32 scheme is suitable for the following scenarios:

Conditions with Extremely High Particulate Matter:Particularly effective in scenarios with super-high particulate content, where the flush liquid assists in maintaining the seal's integrity.

Common Applications in Pulp Pumps:Widely employed in pulp pumps, where the presence of fibers and solids requires a robust flushing solution.

Flushing Solutions for High-Temperature Heavy Oil Pumps:Applicable in high-temperature conditions, especially in heavy oil pumps where efficient flushing is essential.

The PLAN32 scheme, involving external flush liquid injection for mechanical seals, provides an effective solution for challenging conditions with high particulate matter, common pulp pump applications, and high-temperature heavy oil pump flushing. Careful consideration of the flush liquid source is crucial to prevent issues like evaporation or contamination, ensuring optimal performance and reliability of the mechanical seal in diverse and demanding operational environments.
