■ 特点Features

l   泵内置式密封润滑结构，密封循环水对泵密封系统的润滑、冲洗更为直接、有效。

l   直线型的外观并在泵盖上附加加强筋，内置式密封润滑结构使泵整体结构浑然一体，灵活的结构设计使泵更加精美大方。

l   泵体吸入口与吐出口均在泵体的下方，这样可以再不拆卸系列管道的情况下取出转子，维修方便，大部分泵体采用双流道设计，以减小径向力。

l   泵体、泵盖均采用树脂砂板模造型，保证了外观及流到尺寸以及泵的水力效率（不同于一般S、SH干模沙造型）。

l   叶轮进行平衡，确保了泵的运行平稳，噪声降低。

l   轴缩短轴间距，增加轴径，以延长轴承和机械密封的使用寿命，轴为全封结构，确保了不与介质接触，不锈蚀，使用寿命长。

l   轴套根据不同用户的需求可采用多种不同的材料，以防止轴的磨损和锈蚀。

l   轴封采用填料密封或机械密封，可以再不拆卸泵盖的情况下更换密封装置。

l   轴承及润滑采用脂润滑。传动通过弹性联轴器由电动机驱动。

l   旋转方向：正转为从驱动端看为顺时针方向旋转，反转为从驱动端看为逆时针方向旋转。

Pump inner sealing lubrication structure, the sealing circulation water can lubrication and wash the pump sealing system more directly and effect.

The linear appearance and adding strong then on the pump cover, the inside seal lubrication structure make pump structure more beautiful, and the flexible structure design action make pump look more perfect. The inlet and outlet located under the pump, therefore you can take the motor out without disassemble series pipe, it’s convenient to maintain, the most casing adopt double flowing passage designation, so that reduce the caliber direction force.

The casing, pump cover adopt resinic sａnd board mould sculpt, that ensured appearance more beautiful, passing dimension precision and pump’s water power efficiency (It’s different form common S、SH type sculpt).

The impeller is balance, that ensured pump operate reposefully, and have lower noise.

The shaft shorten shaft clearance, long than shaft caliber, in order to prolong the life of bearing and mechanical seal, the shaft is the whole sealing structure, that ensured it not contact with medium, can’t be eroded and prolonged using life.

The shaft cover adopts kinds of different material according to different users’ demand, that prevent shaft be frayed and eroded.

The shaft seal adopts padding seal or mechanical seal, can exchange seal device that needn’t disassemble pump cover.

The bearing and lubrication adopt resinic lubrication. It’s drived by motor through spring coupler.

Rotating direction : it’s clockwise, if seen from driving , and it contra rotate if seen from driving end for opposite rotation.

MSS结构图及主要零部件表

MSS内置密封、润滑、冲洗原理图 (Principle drawing of inside sealing, Lubrication and flushing)：

l   密封冷却、润滑管路一反传统的双吸泵外循环结构，而直接做在泵盖和密封架里，水从泵压出室沿管路进入机械密封腔室（填料），实现了冷却、冲洗、润滑作用，同时防止在泵起动时，空气沿密封处进入吸水室，保证了机组的良好运行。

Sealed cooling and lubrication pipeline departs from the traditional outside-circulation structure of double-suction pumps. It is directly set in the casing cover and stuffing housing. Water from de pump chamber enters into the mechanical seal housing (packing) along the pipe to realize the function of cooling lubrication meanwhile, it prevents the air from entering into the suction room through the seal when pump is started. This ensures a good operation of whole machine.

l   此内置的冷却、润滑、冲洗密封管路结构简单、工作稳定，省掉了繁琐的外循环管路装置，以及因此带来的泵件结构变化。实现了整体结构的紧凑，外形美观。

    The inside cooling 、lubrication and flushing sealed pipeline has a simple structure and stable operation. It reduces the complicated, outside-circulation pipe device as subsequent structure changes of the pump. The more important is it realizes the compactness of whole structure and a nice outline
