Description

technical field [0001] The present invention relates to plunger pumps, in particular to compact high-pressure plunger pumps. Background technique [0002] At present, domestic high-pressure plunger pumps are all assembled in parts, and the internal pipelines are connected in blocks. There are many parts, large volume, and complex structure. Because high-pressure plunger pumps have high requirements for the cleanliness of the oil, it is difficult to guarantee the cleanliness of various parts. , At the same time, there are more scattered connections, which are prone to leakage points. Therefore, the quality of domestic high-pressure plunger pumps has been unstable for a long time, and the main market has been occupied by imported products. Contents of the invention [0003] The object of the present invention is to provide a compact high-pressure plunger pump device with few components, safe and reliable, small volume and convenient maintenance in order to overcome the abov...
