Check valve H41H-10C (HSNH440Q2-46NZ Air-side Sealing Oil Pump Mechanical Seal Maintenance Guide)

Product Introduction

Key Operation & Maintenance Requirements (for HSNH440Q2-46NZ Mechanical Seal)

• Reliable Flushing & Cooling: The HSNH440Q2-46NZ mechanical seal generates significant frictional heat under high pressure and high speed, so reliable flushing and cooling are essential. Connect a low-pressure sealing oil line to the sealing cavity to continuously flush the end face, which removes heat and impurities. Ideally, the oil temperature should be controlled below 40℃; if it exceeds 50℃, check the cooling water pipes for blockages.
• Precise Installation Control: During installation, the end face pressure should not be too high. The spring compression must follow the instructions, generally 5-8 mm, and should be measured accurately with a depth gauge. Excessive pressure will accelerate wear, while insufficient pressure will cause leakage. The contact surfaces of the moving ring and stationary ring must be smooth; before installation, touch them by handthere should be no scratches, otherwise leakage will occur immediately after startup.
