Embodiment
The technical program is in order to save space, using Split type structure, to realize that the conversion of hydraulic energy and machinery, electric signal is defeated
Go out, abandoned traditional microswitch intermediate link, directly changed the adhesive of magnetic element, separation machinery motion by electrode
For the switching of electric signal, the transfer process of microswitch is eliminated；To simplify outside line, reduce extraneous adverse circumstances to electricity
The influence of gas element, the present invention use split-type structural, annex circuit are arranged into internal distribution, connecting wire is directly by signal
Device inner chamber exports, and is connected to by system casing lead hole in electric-control system, eliminates electrical connector module, realizes that installation will
Ask.Without microswitch, electric connector in the structure, reduce the work such as the screening of electric elements, reduce product and safeguard into
This.
Specific embodiment as shown in figure 1, the structure voltage difference signal device include upper shell 1, electrode 2, upper magnetic element 3,
Upper spring 5, magnetic element 7, lower spring 9, high pressure chest pressure-sensitive mouth 13, wire 15, low pressure chamber pressure-sensitive mouth 10, guide sleeve 4, piston
8 spare parts form.The Split type electric pressure difference signal device is plug-in structure, and electrode, connection output are housed in the inner chamber of upper shell
For wire to electric-control system, lower house 6 is respectively arranged with upper and lower magnetic element, high and low pressure chamber pressure-sensitive mouth.Upper magnetic element is by exhausted
Edge glue 17 is fixed on guide sleeve, and magnetic element is fixed on piston by insulating cement.After upper and lower casing has assembled inner body
It is connected through a screw thread and is integrated, in integral installation to system casing.It is connected with wire on electrode to fix by soldering, then by upper
The wire guide output of enclosure interior is connected with the input of electric-control system.Electrode is fixed on upper casing intracoelomic cavity by insulating cement and led to
Cross insulating cement to be fixed in guide sleeve 4, magnetic element is fixed on piston by insulating cement.This split-type structural is in hydraulic pressure system
There is single mounting hole to be installed in parallel with filter core on system housing, set 2 oil ducts to lead to filter core import and export fluid in mounting hole
Corresponding high pressure chest pressure-sensitive mouth, the low pressure chamber pressure-sensitive mouth of signalling means.The polarity of upper and lower magnetic element is paid attention to during assembling, ensures to press
Magnetic element is attracting state up and down after Fig. 1 assemblings.After being bonded magnetic element by Fig. 1, spring 5, lower spring are respectively charged into
9th, spring base 11, then upper shell, lower house are connected as a single entity by screw thread, sealing ring 12, the and of middle part sealing ring 14 are loaded respectively
Upper sealing ring 16 is simultaneously fixed in system by 2 screw holes on upper shell.
The effect of middle part sealing ring 14 is to isolate fluid chamber with electric chamber, and the effect of upper sealing ring 16 is by ambient atmosphere
Isolate with electric chamber, keep electric inner chamber to dry, circuit reliable operation.Lower seal 12 is inner sealing, by fluid into and out of
Oral cavity isolates to establish pressure difference.
This split-type structural has single mounting hole to be installed in parallel with filter core on integrated hydraulic system housing, hole domestic demand
Set 2 oil ducts that filter core import and export fluid is led to corresponding high pressure chest pressure-sensitive mouth 13, the low pressure chamber pressure-sensitive mouth 10 of signalling means,
To ensure that signalling means can experience pressure difference before and after filter core.
During work, during filter core normal work, upper and lower magnetic element is attracting state, and circuit is not turned on；With the working time
Extension, the forward and backward pressure difference of filter core reach as defined in pressure difference when, it is forward and backward that the high and low pressure pressure sensing hole of signalling means experiences filter core respectively
Pressure difference, magnetic element overcome the active force of spring 9 to move down in action of hydraulic force, and upper magnetic element reduces due to suction
Little spring 5 acts on motion upwards and contacted with electrode, and circuit is connected, output alarm signal.When changeing new filter core, signalling means
High and low pressure chamber pressure difference reduces, and magnetic element 7 automatically resets under the active force of lower spring 9, while magnetic force is by upper magnetic element
3 adhesives depart from electrode, and alarm signal is cancelled automatically.Compared with traditional structure, inner chamber is without microswitch, and outside is without electrical connection
Device, save installing space.Wire is exported by upper casing intracoelomic cavity, can meet the internal wiring requirement of system.
