Installation and pressure testing protocols for Lehengoak hydraulic hoses

When routing Lehengoak high-pressure flexible hoses across hydraulic power units and heavy machinery, technicians must avoid twisting the hose around its longitudinal axis.

Assembly personnel follow the continuous embossed layline printed along the outer synthetic rubber cover to ensure straight alignment without torsion.

Minimum bend radius ratings are verified against dimensional engineering charts with an additional ten percent margin, preventing wire braid fatigue cracking during peak hydraulic pressure surges.

Where hoses route adjacent to structural steel framing, heavy-duty polymeric spiral wrap or thermal fire sleeves are secured. Routine inspection of swivel hex nuts and monitoring for outer jacket weeping prevents unexpected pressure loss in fluid power loops.

Assembly standards for DIN 2353 bite-type fluid fittings

Proper installation of DIN 2353 metric bite-type hydraulic tube fittings demands a square cut of precision steel tubing and thorough deburring of internal and external tube rims.

Prior to pre-assembly, assembly lubrication is applied to body threads and the cutting ring wedge cone to reduce friction torque. The union nut is tightened manually to a snug fit, followed by an additional one-and-a-quarter turn with a wrench.

This movement drives the cutting edge of the ring into the outer tube surface, producing a visible retention ridge. Following preliminary assembly, the connection is inspected to confirm uniform ring engagement around the entire circumference.

Final reassembly into the fluid line involves a thirty-degree wrench pull.

Maintenance of mechanical shaft closures and pump fluid seals

Reliable operation of Lehengoak mechanical shaft face seals in process pumping machinery depends on proper flush cooling and effective heat dissipation from sliding friction pairs.

When pumping fluids laden with abrasive fines, an external clean barrier fluid is supplied following API Plan 11 or Plan 53 piping configurations. Prior to electric drive energization, shaft axial float and smooth impeller rotation are checked by hand without binding.

The microscopic lubricating liquid film between the stationary graphite face and silicon carbide rotating ring must never run dry. Routine inspection protocols include checking pump bearing housing temperatures, monitoring seal drainage ports and confirming secondary elastomer O-ring flexibility.

Vibration damping and pipe retention using modular support clamps

To minimize cyclic fatigue stresses across extended hydraulic tube runs, technicians install Lehengoak polypropylene and aluminum modular clamps. Support intervals follow pipe outer diameter guidelines, maintaining spacing under one and a half meters for lines up to twenty millimeters in diameter.

On high-pressure hydraulic circuits, clamps are anchored immediately ahead of pipe bends and in close proximity to manifold block connection ports. The ribbed polypropylene clamp halves absorb mechanical vibration and accommodate thermal expansion of steel piping.

Mounting fasteners are tightened with calibrated torque tools to prevent crushing or out-of-round deformation of thin-walled tubing.

Pressure gauge protection and pulsation damping procedures

Process pressure gauges and pressure switches installed on hydraulic power delivery lines encounter high-frequency pressure pulsations generated by piston pumps.

To prevent premature wear of internal pointer gear mechanisms and Bourdon tube fatigue rupture, instruments are equipped with internal restrictor screws or external coil snubber tubes.

Gauge housings are filled with dampening glycerin or silicone oil, which stabilizes pointer oscillation and cushions internal linkage movement. Zero-point pointer alignment is verified during maintenance shutdowns when line pressure is fully vented.

Annual inspection involves dismounting the units for calibration against deadweight testers to generate traceable verification protocols.

Spray nozzle orifice cleaning and pulverization pattern alignment

The cooling efficiency and tank washing performance of Lehengoak spray nozzles relies on maintaining clean calibrated discharge orifices.

When spray fan uniformity degrades or droplet distribution distorts, nozzles are removed for ultrasonic cleaning in mild solvent baths to remove scale and mineral deposits.

Technicians must never ream nozzle orifices with steel wire or metal picks, because minor scratches on precision edges alter spray angles and increase fluid consumption. Fine mesh line strainers are installed upstream of distribution headers with mesh openings sized at half the orifice diameter.

Regular spray pattern verification ensures complete target area coverage without dry shadows.
