Mechanical insert rim HSNH80Q-46NZ is a high-performance mechanical seal widely used in hydrogen side sealing oil pumps of generators. Its main function is to provide sealing oil for the hydrogen side sealing system to ensure the purity of the gas inside the generator and maintain the appropriate gas pressure.

Features of mechanical insert rim HSNH80Q-46NZ

• Sealing surface: It consists of a fixed sealing ring and a rotating sealing ring, which is the main part to prevent liquid or gas leakage.

• Elastic element: Maintains the pressure between the fixed sealing ring and the rotating sealing ring to ensure a good contact state between the sealing surfaces. Commonly used elastic elements include bellows, springs and O-rings.

• Sealing gasket: Installed on the sealing surface to fill the gap between the sealing surfaces to ensure the sealing effect.

• Fixings: Used to fix the various parts of the mechanical seal to ensure that the sealing parts will not loosen or fall off. Commonly used fixings include screws, clamps and flanges.

• Auxiliary devices: Including cooling water pipes, flushing pipes, exhaust pipes, etc., used to ensure the normal operation and maintenance of mechanical seals.

Application areas of mechanical insert rim HSNH80Q-46NZ

• Generator hydrogen side sealing oil pump: ensure the purity of the gas inside the generator and maintain the appropriate gas pressure.

• Air side oil pump: used for the air side sealing oil system to prevent air from entering the generator.

• Starting oil pump: used for sealing oil supply during startup.

• Ignition oil pump: used for sealing oil supply during ignition.

Maintenance and care

• Pre-startup inspection: ensure that all heating/cooling/flushing/pressure relief systems are in operation. At startup, the exhaust valve installed on the outlet side of the system must be opened until the air on the suction side of the pump is exhausted.

• Steering check: The direction of rotation of the drive motor should be consistent with the direction of rotation arrow on the pump. The direction of rotation can be checked by opening the inlet and outlet valves and instantly connecting the motor. If the direction of rotation is wrong, the pump has no suction, which will damage the pump body components.

• Regular maintenance: Regularly check the wear of the sealing surface and elastic elements, and replace severely worn parts in time.

Mechanical insert rim HSNH80Q-46NZ plays a key role in the sealing system of the generator, ensuring the safe and stable operation of the generator by providing appropriate sealing oil.
