设计特点Design Features

    1.动力端：壳体为钢板焊接结构，焊后消除内应力。动力端传动齿轮为渐开线齿型，运转平稳、效率高、寿命长。曲轴为空心整体铸件。动力端润滑方式为飞溅润滑

    2.液力端：吸入、排出法兰符合ANSI和API规范。

    3.活塞杆与介杆为卡箍连接，可实现快速拆卸。

    4.阀装孔的底部带有台阶，防止阀座下沉。活塞和缸套由一个独立的喷淋泵装置冷却和润滑，使用寿命长。

    5.易损件通用性强。

The power end :The frame is welded steel-plate construction. It is stress-relieved after welding. The drive gears are involute type gears which allow smooth operation, high efficiency and long life. The crankshaft is a hollow one-piece steel casting. The power end is either splash or pressure lubricated.

The fluid end: The suction and discharge flanges conform to ANSI and API specifications.

The piston rod includes an intermediate rod, that allows quick assembly & disassembly.

The valve seat bores have a bottom shoulders. The pistons and liners are spray lubricated and cooled, which allow an extended service life

Damageable pieces have strong currency.
