Abstract
The invention discloses an electromagnetic hydraulic pump, and particularly relates to the field of plunger hydraulic pumps. N sets of independent reciprocating electromagnetic plunger pump units are formed by N plunger coupling parts and N electromagnets. The N sets of independent reciprocating electromagnetic plunger pump units can be controlled by a PLC to independently work or simultaneously work according to pressure changes and flow changes. The electromagnetic hydraulic pump has the advantages of being simple and compact in structure and light. Due to the fact that the N sets of electromagnetic plunger pump units can be independently started, the starting loads are small.
