- Combined structure of steel hard pipe and flexible rubber hose, rigid pipe keeps pipeline shape, hose absorbs frame vibration, reduce fatigue cracking risk at welding positions.
- Smooth inner pipe wall, low flow resistance, reduce cooling circuit back pressure, guarantee stable circulation of transmission oil and improve heat dissipation efficiency of dual variator system.
- Multi-layer steel wire braided hose and high-temperature resistant nitrile rubber seal, good resistance to transmission oil corrosion and pressure pulse, effectively prevent oil leakage under high oil temperature.
- Strict welding and surface anti-corrosion treatment for steel pipes, strong rust resistance, adapt to dusty, humid construction site environment, extend pipeline service life.
- Complete assembly with pipe clamps, gaskets and joints, one-piece delivery, convenient for on-site maintenance and rapid replacement.
- Reasonable pipeline layout without sharp bends, reduce air accumulation inside the loop, avoid local overheating and cavitation of dual variator system, protect clutch friction plates.

FAQ 

Q1: Is this dual variator oil cooler pipeline assembly compatible with both ZL50G and ZL50GL?
A1: Yes. This pipeline assembly is customized for XCMG ZL50G and ZL50GL wheel loaders. Pipe layout, flange size and connector specifications are universal for the two models.

Q2: What are typical symptoms that the dual variator oil cooler pipeline needs to be replaced?
A2: Oil leakage at welding seam or hose joint, hose bulging, cracks and oil seepage, hard pipe serious corrosion or deformation, pipeline blockage which leads to continuous high transmission oil temperature and power weakness during shoveling.

Q3: What routine maintenance should be carried out for dual variator oil cooler pipeline?
A3: Regularly inspect pipeline surface for cracks, swelling and oil leakage; check tightness of pipe clamps and flange bolts; avoid external collision and extrusion of pipeline; keep pipeline surface clean, regularly check transmission oil quality.

Q4: Is pressure test and leakage inspection carried out before delivery?
A4: Every pipeline assembly will pass hydraulic pressure test and sealing leakage inspection before leaving factory to ensure no leakage under rated working pressure.

Q5: Can high-pressure water gun directly wash the dual variator oil cooler pipeline?
A5: Not recommended. High-pressure water may impact the hose surface and sealing joints, accelerate aging of rubber parts. Clean dust with compressed air or wet rag.

Q6: What hazards will occur if the pipe clamp is loose for a long time?
A6: Loose pipe clamps will cause pipeline shaking and resonance during operation, resulting in fatigue fracture of welding seams or hose joints, leading to sudden transmission oil leakage, power drop and affecting machine safety.
