Work.
The check valve valve core of the present invention keeps the position being pressed in vertically downward on valve seat, in order to avoid valve core jam；Commutation should be made
Guiding valve keeps axis level orientation, in case causing from hanging down for valve core, electromagnet part is commutated and resetted not normal.Flow divider-combiner
Valve core should be axis horizontal orientation, in order to avoid reduce its synchronization accuracy.
The oil circuit board of the hydraulic power unit of the present invention, in order to reduce the hole number on oil circuit board, shortens drilling depth, can take
Following measures： 1）Make to have in hydraulic system that associated control element is adjacent to be laid as far as possible.If 2) certain two control element has
Hydraulic fluid port is communicated, then should make two communicate hydraulic fluid port line and oil circuit board certain-side is parallel, to reduce the number of cross-drilled hole on oil circuit board.Valve
1 A holes will be communicated with the B holes of valve 2, and the arrangement of two valves makes A holes identical with coordinate dimension in the X-axis in B holes, and boring two straight holes can
Connect A, B holes.If conversely, the X-axis coordinate dimension in two holes it is different it is necessary to increasing-individual cross-drilled hole, when what is disposed on oil circuit board
When number of elements is more, to avoid the duct that should not be connected from communicating, drilling should be layered, still, layering drilling increases oil circuit board
Thickness and weight.Close to Hydraulic Elements ground drill with ferrule the-layer hole, do draining and and control oil passage, their diameter compared with
It is small；Second layer hole is the cross-drilled hole of logical pressure oil；Third layer hole is oil return hole path.To prevent oil pressure effect from puncturing adjacency channel,
Wall thickness between Kong Yukong-as cannot be less than 5mm.In order to improve the functional reliability of oil circuit board, pressure oilhole is calculated or checked
Between minimum wall thickness (MINI W.), it is met intensity requirement.When number of elements is less, two layers of drilling, or only arrangement-layer hole can be divided
To link up each element by system requirements and reducing drilling depth ,-a little fabrication hole, last process hole plug screw can be suitably arranged
Block, each pressure measurement oilhole of pressure meter switch is circumferentially arranged, and aperture is smaller, distribution is closeer, be difficult on oil circuit board direct cloth
Put and use the connection of plate outer pipe type more convenient.
