镀锌专用抽锌泵

Special Galvanizing Zinc Pump

　　热镀锌厂家因锌锅正常维护保养和锌锅渗漏抢险等特殊情况须将锌液全部滔出来，往常只用人工从锌锅中滔出，其劳动量之大，劳动强度之高，一般人是难以承受的。如果改用抽锌泵来抽取锌液，按***低流量30吨/小时来计算，抽100吨锌也只不过3个多小时，这样不但大大的缩短了时间，提高了生产效率，而且也把工人从繁重的体力劳动中解放出来，极大的减轻了工人们的劳动强度，同时也避免了高温、锌液飞溅对人们的伤害，提高热镀锌厂家的经济效益。

Hot-dip galvanizing manufacturers must remove all the zinc liquid due to the special conditions such as the normal maintenance of the zinc kettle and the leakage of the zinc kettle. Usually, they are only manually removed from the zinc kettle. The labor is large and the labor intensity is high. It is unbearable. If you use a zinc pump to pump zinc, according to the minimum flow of 30 tons / hour, pumping 100 tons of zinc is only more than three hours, which not only greatly shortens the time, improves production efficiency, but also puts workers liberation from heavy physical labor, which greatly reduced the labor intensity of workers, and also avoided the damage of high temperature and zinc splash to people, and improved the economic benefits of hot-dip galvanizing manufacturers.

　　抽锌泵主要是利用高速旋转的叶轮所产生的离心力将锌液甩出，它和普通离心泵不同的只是其工作介质有所区别。抽锌泵的叶轮、壳体、密封套等主要部件全部采用德国进口的耐锌蚀合金钢制造，有效地控制了锌液在泵中的流速、温降、材料的热膨胀系数等各项指标，满足长时间反复循环使用的特殊要求，深受热镀锌单位的欢迎和青睐。

The zinc pump is mainly used to extract the zinc liquid by the centrifugal force generated by the high-speed rotating impeller. The difference from the ordinary centrifugal pump is that the working medium is different. The main components of the impeller, casing and sealing sleeve of the zinc pump are all made of zinc-resistant alloy steel imported from Germany, which effectively controls the flow rate, temperature drop and thermal expansion coefficient of the zinc in the pump. It meets the special requirements of long-term repeated recycling and is welcomed and favored by hot-dip galvanizing units.

主要特点 Main features：

　　1、采用立式长轴转动方式(一般在2米以上)，以使驱动电机远离热源，确保电机能够长时间的正常工作。

  Adopt vertical long-axis rotation mode (generally more than 2 meters) to keep the drive motor away from the heat source and ensure the motor can work normally for a long time.

　　2、泵体与驱动装置间采用开放式框架结构，以便观察锌液面低漫时泵轴与外壳间的粘联情况。

An open frame structure is adopted between the pump body and the driving device to observe the adhesion between the pump shaft and the outer casing when the zinc liquid surface is low.

　　3、在泵轴上装有手轮，随时防止并检测锌泵叶轮、壳体是否被低温锌液抱住。

Install the hand wheel on the pump shaft to prevent the zinc pump impeller and the casing was caught by the low temperature zinc liquid at any time.

　　4、锌液泵叶轮、壳体采用耐锌蚀的特殊合金钢，具有耐高温、防腐蚀、耐磨等特点、以延长锌泵的使用寿命。

The impeller and shell of the zinc liquid pump adopt special zinc alloy corrosion resistant alloy steel, which has the characteristics of high temperature resistance, corrosion resistance and wear resistance to prolong the service life of the zinc pump.

　　5、采用长间距、双列调心轴承，以提高锌泵的运转平稳度。

Use long-pitch, double-row self-aligning bearings to improve the smoothness of the operation of the zinc pump.

　　抽鋅泵使用方法 Zinc pump instructions：

　　抽锌泵是在考虑了锌液温度高、比重大、且易凝固等诸多因素而设计的，正确的使用方法，将是确保其能够长期使用的前提保障。

The zinc pump is designed with many factors such as high temperature, large specific gravity and easy solidification. The correct method of use will ensure the long-term use of the zinc pump.

　　其操作步骤说明如下The operation steps are as follows：

　　1、抽锌前必须对锌液泵进行外观检查，用手转动手轮，确定没有异常感觉，即可通电观察泵的旋转方向是否与标示方向一致。

Before pump the zinc, the zinc liquid pump must be visually inspected. turn the hand wheel by hand to make sure there is no abnormal feeling. you can observe the rotation direction of the pump in the same direction as the marking direction.

　　2、用吊具将锌泵吊起，并直立缓慢地放入锌液中(此时泵不能通电)，其泵壳底面浸入锌液的深度约200-300mm左右。

The zinc pump is lifted by a spreader and slowly placed in the zinc liquid in vertical (the pump cannot be energized), and the depth of the zinc liquid immersed in the bottom of the pump casing is about 200-300 mm.

　　3、当锌泵浸入锌液的瞬间，液态的锌液会立即凝固在泵体上，并将转动轴、叶轮、外壳抱死，这是泵体温度低而造成的锌液凝固现象，这不要紧，此时可将泵体在锌液中来回悠荡，以加速这些凝固锌液的溶化程度。此段时间，是锌泵的预热过程，当泵体温度与锌液温度平衡时自然消失。

When the zinc pump is immersed in the zinc liquid, the liquid zinc liquid will immediately solidify on the pump body, and the rotating shaft, the impeller and the outer casing will be locked. This is the zinc solidification phenomenon caused by the low temperature of the pump body, which does not matter. The pump body can be swayed back and forth in the zinc liquid to accelerate the melting of these solidified zinc liquid. This period of time is the preheating process of the zinc pump, which naturally disappears when the temperature of the pump body is balanced with the temperature of the zinc liquid.

　　4、当泵体在锌液中浸泡5-10分钟后，用手转动手轮，若此时传动轴转动自如，即说明放入时凝固的锌已被溶化，此时即可通电抽锌。

When the pump body is immersed in the zinc solution for 5-10 minutes, turn the hand wheel by hand. If the drive shaft rotates freely, it means that the zinc solidified when it is placed has been melted, and then can be energized to pump the zinc liquid.

　　5、当泵通电旋转后，泵口也可能不会立即出锌，这是出锌管与锌液进行热交换或泵体进行间隙自调整的过程。如果在泵动5-10分钟后仍然没有锌液流出，此时可加大锌液泵浸如锌液的深度，但***大不得超过400mm。

When the pump is energized and rotated, the pump port may not immediately release zinc. This is the process of heat exchange between the zinc tube and the zinc liquid or the gap adjustment of the pump body. If there is still no zinc liquid flowing after 5-10 minutes of pumping, the depth of the zinc liquid pump immersed in zinc liquid can be increased at this time, but the maximum is not more than 400 mm.

　　6、在抽锌的过程中，由于锌液面的下降，锌液泵也必须随之下降，以保证浸入深度。

During the zinc extraction process, the zinc pump must also be lowered due to the drop of the zinc level to ensure the immersion depth.

　　7、在需要停止抽锌时，必须先断开泵电源，然后将泵提出锌液面，待出锌管中的锌液回流完后，立即重新起动锌泵，以便将叶轮、壳体上沾附的余锌甩掉，这一过程直到锌液泵的温度降低到很多为止，这里必须指出的是：当锌液泵停止转动后，很可能被重新抱死，这是轴套间隙内残锌凝固所造成的，属正常状态，在下次使用时按上述第3条的办法即可解决。

When its necessary to stop the zinc extraction, the pump power must be disconnected, and then lifting the pump from the zinc liquid surface. After the zinc liquid in the zinc tube is returned, the zinc pump is restarted to adhere the impeller and the casing to smashed the residual zinc. This process will stop until the temperature of the zinc pump has dropped a lot. when the zinc pump stops rotating, it is mostly to be re-locked again. This is the reason of residual zinc solidification in the sleeve gap. The resulting situation is normal and can be resolved in the next use according to the above Article 3.

　　8、抽完锌后的锌泵，由于温度很高，应采用悬空冷却，在温度没有降低很多之前(约30分钟)严禁将泵体落地，以免因碰撞变形而影响日后的继续使用。

After the zinc pump is exhausted, due to the high temperature, it should be suspended and cooled. Before the temperature is not reduced much (about 30 minutes), it is strictly forbidden to land the pump body, in order to avoid the impact deformation and affect the use of future.
