Gear pump is a common positive displacement pump, which mainly consists of two gears, pump body, and front and rear covers to form two enclosed spaces. The most obvious feature of gear pump is its simple structure, light weight, low cost, reliable operation, and wide application range. Next, let's learn about the techniques to prevent gear pump blockage?

 

1、 Internal issues with the gear oil pump have led to blockages. Gear oil pump is powered by the impeller to guide oil into the pipeline. If there is a problem with the impeller or other components, it can cause problems with the filtration and transmission systems of the oil pump. Some substances that can be filtered can be filtered out when they enter the gear oil pump. Once the filtration system has a problem, these impurities cannot be filtered out and blockage is inevitable.

 

 

2、 The gear oil pump forgot to install a filter screen at the inlet during operation. This situation is also very common. Nowadays, filter nets are divided into many sizes and different types, just like fishing nets. The filter net is the first layer of filtration when the transported oil enters the oil pump for the first time. It will exclude many impurities from the oil pump and allow pure oil to enter the pump. Without this filter, any substance entering the oil pump will eventually cause problems.

 

3、 Some impurities or other items have entered the interior of the oil pump, blocking its transmission channel. This is the most common reason, especially when transporting newly extracted oil, there may be impurities and other substances mixed in, some of which are solid and some have a high density. These substances entering the gear oil pump will block its inlet or outlet, leading to a decrease in its transportation efficiency. The most common solution to this situation is to promptly clean the blockages inside the oil pump to keep it unobstructed.
