动力端power end

⑴ 机架采用钢板焊接件,强度高,刚性好,重量轻。

The frame adopts the steel plate weldment with high strength, good rigidity and lighter weight. 

⑵ 整体人字齿轮传动,运转平稳. 

One-piece herringbone gear drive with smooth running.

⑶ 合金钢曲轴。可更换的十字头导板。 

Alloy steel crankshaft and changeable crosshead guide. 

⑷ 采用滚子轴承,提高了运转时的平稳性和承载能力。 

Adopt roller bearing and improve the running stability and load capacity. 

⑸ 中间拉杆盘根采用先进密封结构,密封效果好。 

The extension rod adopts advanced packing structure with good seal performance. 

⑹ 动力端齿轮、轴承、十字头等部位采用强制润滑和飞溅润滑相结合的润滑方式。 

Gear, bearing, crosshead and some other parts at power end adopts forced lubrication and splash lubrication mode. 

⑺ 应用施必牢防松螺母,拆装方便。 

Adopts Spiralock self-locking nuts and easy to assembly and disassembly.

液力端hydraulic end

⑴ 液缸采用直通式布置,可使液流平稳、结构紧凑、容积效率高。 

The cylinder adopts the go-through laying (over & under valves-front loading) to make the flow smooth, structure compact and with high volumetric efficiency. 

⑵ 三个液缸具有互换性。 

The three cylinders are interchangeable. 

⑶ 缸盖和阀盖能快速旋紧,装拆方便。 

The cylinder cover and valve cover can be screwed down quickly and convenient to disassembly and assembly.

⑷ 吸入阀和排出阀能通用互换。

Suction valve and discharge valve can interconvert. 

⑸ 采用敞开式的活塞与缸套内腔结构,便于观察。 

Adopt the opened piston and cylinder liner structure and convenient to observe.
