由于这种泵的结构和螺杆间存在的侧间隙，它可以输送非润滑性介质。
Owing to the pump structure and side clearance between screw, it can transport non-lubricative medium.
所以选择不锈钢材质的高粘度泵是一定要注明具体的使用温度，及介质的润滑性。
So choose stainless steel high viscosity pump is must indicate the specific temperature, and medium lubricity.
润滑脂：普通润滑脂或泵用重水润滑脂。
Lubricating grease: General grease or heavy water grease used for pump.
注入润滑脂时必须旋转泵轴，以使其充分进入填料腔，直到填料压盖端有油脂渗出为止。
Sure to rotate the pump shaft when pouring lubricating grease, in order that the grease can get into packing cavity fully until have grease oozed out from gland.
因此，提高推力瓦、镜板检修质量；改善润滑性能、冷却器冷却效果等对解决大型立式循环泵推力瓦轴承磨损有重要意义。
Therefore, the improvement of repairing quality, lubrication and cooling performance of cooler is very important for the abrasion problem of thrust bearing to be solved.
正常情况下使用普通润滑脂，泄漏过大则最好使用泵用重水润滑脂。
Under the normal condition use general lubricating grease, you had best use heavy water lubricating grease for pump if too much leakage loss.
为了实现润滑脂在管路中输送的无流量脉动，研制了一种低流量脉动泵。
In order to realize the transportation of grease without flux pulse in the tube, a low-flux pulse pump was developed.
⤤高粘度泵容易出现的另一个问题就是从动齿轮的销轴容易磨损，特别是对于输送没有润滑性的介质时，销轴磨损特别快。
Another problem of the high viscosity pump is driven gear pin easy to wear and tear, especially for conveying without lubrication medium, pin shaft wear particularly fast.
所有润滑脂油嘴均安装在泵支撑板顶部。
All grease fittings are installed on top of the pump support plate.
高粘度泵可以输送高粘度、高浓度无固体颗粒或细小软颗粒的润滑性介质；
High viscosity pump can transport high viscosity, high concentration without solid particles or small soft particles lubricity medium;
齿轮泵适用于输送不含固体颗粒、无腐蚀性、粘度范围较大的润滑性液体。
The gear pump is suitable in the transportation does not contain the solid particle, non-corrosiveness, the viscosity scope big lubricating ability liquid.
高粘度泵容易出现的另一个问题就是从动齿轮的销轴容易磨损，特别是对于输送没有润滑性的介质时，销轴磨损特别快。
Another problem of the high viscosity pump is driven gear pin easy to wear and tear, especially for conveying without lubrication medium, pin shaft wear particularly fast.
