Problems solved by technology
The ambient temperature of the traditional electro-hydraulic proportional control multi-way reversing valve cannot exceed 80°C, while the temperature of the forklift hydraulic oil often exceeds 80°C. Due to the limitation of electromagnetic characteristics of the multi-way reversing valve, this has caused defects such as high failure rate and poor reliability in actual use.

Description
technical field [0001] The invention relates to an electronic control device for an integrated electro-hydraulic proportional control system, in particular to an electronic control device for an integrated electro-hydraulic proportional control system for construction machinery and special vehicles such as forklifts. Background technique [0002] The multi-way reversing valve of the hydraulic system of the hydraulic forklift adopts a two-way self-holding electromagnet and adopts a double-coil structure. performance permanent magnet. When the coil is energized, the shaft core produces an axial displacement. After the power is turned off, under the action of the closed magnetic field of the permanent magnet, the position of the shaft core after the power-on displacement can be maintained (self-locking), without the need for power input to maintain. Attraction and reset are driven by pulse power. It has the advantages of low power consumption, small temperature rise, and high...
