老式抽油方法是用一个活塞式手拉泵的管子伸到油桶的底部,然后使劲上下拉动活塞拉手才能使油桶中的油抽入容器,如用力过猛会使油溅在身上。同一泵的管子抽完一种油,再去抽另一种油,会把不同种类的油混在一起而影响油的质量。同时,还容易污染环境。为此,我们设计了方便抽油装置。 Old-fashioned pumping method is to use a piston-type hand-held pump tube extends to the bottom of the drum, and then pull the piston up and down hard to pull the oil in the drum into the container, such as excessive force will splash on the body. The same pump pipe pumping an oil, and then pumping another oil, will mix different types of oil and affect the quality of oil. At the same time, it is also easy to pollute the environment. To this end, we designed a convenient pumping unit.
