The гидравлический цилиндр ковша в сборе is an essential part of an excavator’s attachment system, позволяя машине подбирать, перевозить и разгружать грузы. 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:
- The hydraulic cylinder itself – Which actuates the linkage system
- Штыревые соединения – Attaching the cylinder to the boom and bucket
- Втулки, seals and bearings – Within the pins and cylinder rod
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:
- Поршень – Воздействует на гидравлическую жидкость, выдвигая или втягивая шток.
- Стержень – Connects to the bucket linkage and transmits force
- Трубка цилиндра – Вмещает поршень и шток в сборе.
- Морские котики – Предотвратите утечку жидкости вокруг поршня и штока.
- Втулки – Уменьшите трение внутри штифтовых соединений.
Maintaining About Excavator Hydraulic Cylinders
Regular maintenance should include:
- Checking for leaks – Around seals, шланги, fittings and cylinders
- Inspecting rods/tubes – For dents, scratches or excessive wear
- Lubricating bushings and pins – With grease every 50 часы
- Checking hoses/fittings – For cracks, damage or loose fittings
- Тестирование полного диапазона движений – Цилиндры должны двигаться свободно
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
