What standards do these deck frame air line parts comply with? Are they compatible with ZJ40 truck-mounted drilling rigs?

All parts comply with API Spec 7K (drilling equipment standard) and EN ISO12100:2010 (mechanical safety standard), which are authoritative standards for oil and gas drilling equipment. They are specifically designed for ZJ40 truck-mounted drilling rigs, with precise dimensions and good compatibility, ensuring direct replacement and stable operation without modification.

2

How often should the key components (such as hose assemblies and filter elements) be replaced under normal drilling conditions?

Under normal drilling conditions (8 hours of daily operation, moderate environmental corrosion), hose assemblies should be replaced every 12 months; filter elements of the filter assembly should be replaced every 6 months; the adsorbent of the drier assembly should be replaced every 12 months; rubber gaskets of pipe clamps should be replaced every 8 months. For harsh environments (high temperature, high corrosion, high vibration), the replacement cycle should be shortened by 30%.

3

What should I do if air leakage occurs in the deck frame air line system? How to quickly locate the fault point?

First, turn off the air supply and release the residual pressure in the system. Then, apply soapy water to the connection points (bushings, fittings, hose joints), and the position where bubbles appear is the air leakage fault point. Common causes include worn bushings/fittings, damaged sealing rings, loose connections, or cracked hoses. Replace the worn parts, tighten the loose connections, or replace the cracked hoses to solve the problem. For complex faults, refer to the on-site maintenance case mentioned above or contact our technical team for support.
