The boom and arm cylinder assemblies are critical components of an excavator’s lifting and digging system. Proper maintenance and timely replacement of hydraulic cylinders and related parts ensures optimal excavator performance and productivity.
Function Of Boom and Arm Cylinder Assemblies
O conjunto do cilindro da lança consists of:
- The hydraulic cylinder – Which pivots the boom up and down
- Pin connections – Attaching the cylinder to the boom and the base
O Conjunto do cilindro do braço inclui:
- The hydraulic cylinder – Which actuates the articulating arm linkage
- Pin connections – Attaching the cylinder to the arm and boom
The hydraulic cylinders work by:
- Estendendo e retraindo suas hastes em resposta à pressão hidráulica
- Aumentar e abaixar o boom e os braços
- Abrindo e fechando o braço articulado na junta
Componentes de cilindros hidráulicos de escavadeira
Os cilindros hidráulicos usados nos conjuntos de lança e braço incluem:
- Piston – Acts on the hydraulic fluid to extend or retract the rod
- Rod – Connects to the boom or arm and transmits force
- Cylinder tube – Houses the piston and rod assembly
- Seals – Prevent fluid leakage around the piston and rod
- Bushings – Reduce friction within the pin connections
Mantendo cilindros hidráulicos da escavadeira
A manutenção de rotina deve incluir:
- Verificando vazamentos em torno de focas, cylinders and hoses
- Inspecionando hastes/tubos para amassados, arranhões ou desgaste excessivo
- Buchas lubrificantes e alfinetes com graxa a cada 50 horas
- Verificando mangueiras/acessórios para rachaduras, danos ou acessórios soltos
- Testing for full range of motion – Cylinders should move freely
Proper maintenance and timely replacement of the boom and arm cylinder assemblies is critical to maximizing the performance, productivity and life of an excavator. Cilindros hidráulicos negligenciados ou desgastados podem reduzir drasticamente a eficiência da escavadeira, Operadores de custos tempo e dinheiro.
