O conjunto de cilindro de caçamba hidráulica is an essential part of an excavator’s attachment system, enabling the machine to pick up, carry and dump loads. Proper maintenance and timely replacement of hydraulic cylinders and related parts is critical for optimal excavator performance and productivity.
Function Of The Bucket Cylinder Assembly
The bucket cylinder assembly consists of:
- O próprio cilindro hidráulico – Which actuates the linkage system
- Conexões de pino – Attaching the cylinder to the boom and bucket
- Buchas, vedações e rolamentos – Dentro dos pinos e da haste do cilindro
The hydraulic cylinder works by extending and retracting its rod in response to hydraulic pressure from the excavator’s pump. This motion:
- Raises and lowers the excavator bucket
- Opens and closes the bucket to grab and release material
Components Of Excavator Hydraulic Cylinders
Hydraulic cylinders used in bucket assemblies include:
- Pistão – Atua no líquido hidráulico para estender ou retrair a haste
- Haste – Connects to the bucket linkage and transmits force
- Tubo do cilindro – Abriga a montagem do pistão e haste
- Selos – Evite vazamento de fluido ao redor do pistão e haste
- Buchas – Reduzir o atrito nas conexões do PIN
Maintaining About Excavator Hydraulic Cylinders
Regular maintenance should include:
- Checking for leaks – Em torno das focas, mangueiras, fittings and cylinders
- Inspecting rods/tubes – Para amassados, arranhões ou desgaste excessivo
- Lubricating bushings and pins – Com graxa cada 50 horas
- Checking hoses/fittings – Para rachaduras, danos ou acessórios soltos
- Testes para amplitude de movimento total – Os cilindros devem se mover livremente
Signs It’s Time To Replace Cylinders:
- Rods bent or dented
- Seals leaking excessively
- Rod/piston extending unevenly
- Excess friction and binding
- Lack of full range of motion
Benefits Of Replacing Worn Cylinder Assemblies:
- Improved digging and lifting power
- Faster cycle times for faster productivity
- Smoother, more controlled bucket movement
- Reduced hydraulic system strain and wear
- Less unexpected breakdowns and downtime
