从目前的微型齿轮泵的市场而言，大家也能看到我国高温齿轮泵每年生产数量的一半用来更换报废产品,因此,如何选择到一台经久耐用,称心如意的齿轮油泵和怎样延长齿轮油泵的寿命就成为广大用户十分关心的问题.今天微型齿轮泵厂家就为大家来解决这个问题。高温齿轮泵结构和KCB齿轮泵结构大致相同，主要有齿轮、轴、泵体、安全阀、轴端密封等组成。齿轮都经热处理有较高的硬度和强度（使用寿命要比普通的齿轮泵要长很多），齿轮与轴一同安装在可更换的轴套内运转。泵内所有零部件都是通过所输送的介质润滑。

From the current market of micro gear pump, you can also see that half of the annual production of high temperature gear pump in China is used to replace scrap products. Therefore, how to choose a durable, satisfactory gear pump and how to prolong the service life of gear pump have become a major concern of users. Wheel pump manufacturers to solve this problem for everyone. The structure of high temperature gear pump is similar to that of KCB gear pump, mainly consisting of gear, shaft, pump body, safety valve and shaft end seal. Gears have higher hardness and strength after heat treatment (their service life is much longer than that of ordinary gear pumps). Gears and shafts are installed in replaceable sleeves to operate together. All parts in the pump are lubricated by the medium conveyed.

提高高温齿轮泵的使用寿命尤为重要。

It is particularly important to improve the service life of high temperature gear pump. 1、因泵体在高温下运转，故冷态安装时配管上应设铰支座，以防升温后配管位移。

1. Because the pump body operates at high temperature, hinged support should be installed on the piping during cold installation to prevent piping displacement after heating.

2、高温齿轮泵出口后面的熔体过滤器要定期更换，不要长期在高压乃至压力上限运行。

2. The melt filter behind the outlet of the high temperature gear pump should be replaced regularly, and it should not run at high pressure or even at the upper limit of pressure for a long time.

3、安装进出口管道时，应先对管道内壁用煤油清洗干净。

3. When installing the import and export pipeline, the inner wall of the pipeline should be cleaned with kerosene first.

4、在室外安装，当气温低于-5℃时应对泵的外部采取保温措施以防泵体开裂或影响泵的正常工作。齿轮泵的底座应固定在牢固的地基上，以免产生振动影响泵的正常工作。

4. Installation outdoors, when the temperature is below - 5 C, the external insulation measures should be taken to prevent the cracking of the pump body or affect the normal operation of the pump. The base of gear pump should be fixed on a solid foundation to avoid vibration affecting the normal operation of the pump.

5、联轴器必须在泵体升温后热找正，以避免运转时造成附加力矩。

5. Coupling must be heat-aligned after the pump body is heated to avoid additional torque during operation.

6、泵出口压力测点要设联锁停止报警，否则，一旦排出管道受阻，易造成泵体损坏。

6. Pump outlet pressure measurement points should be interlocked to stop alarming, otherwise, once the discharge pipeline is blocked, it will easily cause damage to the pump body.

7、定期更换齿轮、轴就可，泵体相对磨损较慢。

7. The gear and shaft can be replaced regularly, and the relative wear of the pump body is slower.

针对以上这些微型齿轮泵厂家分析怎样延长高温齿轮泵使用时间，大家在操作中需注意使用，多了解详情而用。

In view of these micro gear pump manufacturers to analyze how to prolong the use time of high temperature gear pump, we need to pay attention to the use in operation, more details and use.
