Application of excavator hydraulic cylinder: For Daewoo Cylinder Seal Kit,For Daewoo Riser Repair Kit,Riser Repair Kit,Rotary Motor Seal Kit Safe Seal Technology Co., Ltd. , https://www.jolseals.com
1. ApplicationÂ
 It applies to delivering non-corrosive lubricating -oil ior equivalent liquid without solid particles and fibres at temperature below 300ºC and with the viscosity of  5~ 1500 cst.
 Reducing the speed, the pump can delivery the liquid that the viscosity can be up to 5*10000 cst.
2.Application Scope
 It can give performanceas transfer pump or booster pump in oil delivery system. It can be also applied as fuel pump for delivery system, pressurization and injection in fuel supply system and in all industry fields as lubrication pump.
 KCB series gear pumps are mainly composed of gears, axles, pump body, pump cover, safety valve and axle-end seals etc. The heattreated gears have the advantage of higher hardness and intensity, and rotate with the axles inside the replaceable bearing sleeves. All of pump's parts can be lubricated by delivered medium when working.
 The pump is properly designed with leakage and return chute, which lets the gears bear the least torque force and reduces load and wear on bearings in order to raise pump's efficiency.
 It is alsp disigned with safety valve for protection against overload.The full return flow pressure of the safety valve is 1.5 times higher than the rated exhaust pressure of the pump. It can be also adjusted within the allowance of exhaust pressure range according to circumstances. But  please note the safety valve can not be applied as pressurereducing valve for long time.Â

The hydraulic cylinder of an excavator is an important component, mainly used to control the movement of the excavator's mechanical arm, stick, bucket head, and other parts. Specific application scenarios include:
1. Construction engineering: Excavator hydraulic cylinders can be used for excavation and transportation of earthwork, excavation of foundation pits, road construction, pipeline laying, and other construction projects.
2. Mining: Excavator hydraulic cylinders can be used for ore mining, blasting, transportation, and loading in mining.
3. Agricultural production: excavator hydraulic cylinder can be used for Land consolidation, irrigation and drainage, ditch excavation, crop harvesting and other work in agricultural production.
4. Hydraulic engineering: Excavator hydraulic cylinders can be used for river dredging, embankment construction, reservoir construction, and other work in hydraulic engineering.
5. Garbage treatment: The excavator hydraulic cylinder can be used for garbage cleaning, compression, transportation, and landfill in garbage treatment.
In summary, excavator hydraulic cylinders are widely used in various engineering and production fields, and are important tools for improving work efficiency and production efficiency.
