Guide bearings made from conventional materials often encounter issues such as wear, vibration, seizure, cracking, and adhesion during operation, leading to component damage or even forced shutdowns.
Our company has developed a new type of guide bearing made from a self-lubricating material using the conveyed medium. This innovation addresses the following common problems:
Wear, erosion resistance, and corrosion resistance: Conventional materials often fail to meet the operational demands in these areas.
Thermal expansion and contraction: The design clearance of dynamic and static parts can be compromised due to the effects of temperature changes.
Cracking under extreme conditions: Special operating conditions, such as extreme cold or heat, can cause the material to crack.
These guide bearings are mainly used in turbines, large vertical pumps, and similar equipment, offering enhanced durability and reliability.
A: We deliver customized sealing solutions to diverse industrial sectors,including:
·Oil and Gas
·Refining
·Chemical and Petrochemical
·Water and Wastewater Treatment
·Pharmaceutical
·Power Generation
·Marine
Our products are designed to perform reliably in demanding environments across multiple industries.
A: HQ Seals provides custom sealing solutions customized for your working conditions. We manufacture seals according to:
· Technical drawings
· Physical samples
· Special material & performance specifications
· Non-standard sizes
We maintain close communication with clients to guarantee all finished products satisfy operational and environmental requirements.
A: First, identify the optimal configuration (single or double seal) according to the process fluid. Then verify operating parameters — pressure, temperature and shaft speed — to select the appropriate seal type and materials. Lastly, confirm available installation dimensions, and opt for either a component or cartridge seal subject to customer requirements and relevant standards. Seal selection is normally carried out by qualified technicians.
A: For mechanical seals that have been stored for a long period: we can grind the rotating and stationary rings, replace secondary sealing O-rings, conduct air tightness testing and issue the pressure test report.
We can provide on-site installation guidance service. For failed mechanical seals, we are able to deliver failure analysis reports.
A: Yes, repairs are available. Depending on the damage condition of the mechanical seal, we classify the overhaul into Level 1, Level 2 and Level 3 repair.
