Technical field
The invention belongs to technical field of hydraulic, and in particular to a kind of triplex redundance servo valve quickly fills demagnetizing method.
Background technology
Triplex redundance servo valve is a kind of servo valve with three prestage redundancy structure designs, my unit be it is domestic most
The early unit developed and produce triplex redundance servo valve, the product of development are successfully used for manned space flight carrier rocket model, commonly
Servo valve only has a prestage, totally three zero-bits (hydraulic null, mechanical zero, electromagnetism zero-bit), and triplex redundance servo valve has
Three prestages, thus have 9 zero-bits, and three prestage flow gain coherence requests are high, cause debugging difficult.
Prestage is made of permanent magnet, upper and lower magnetizer, control coil and armature component, is carrying out electromagnetism zero-bit debugging
When need to make electromagnetism null balance by prestage fill the method for demagnetization, the part because forming prestage most of is magnetic conduction
Material, it is more sensitive to magnetic field, in order to avoid three prestages influence each other in magnetic field, the electromagnetism zero-bit of triplex redundance servo valve
Debugging individually must debug each prestage, thus whole debugging process need to assemble and disassemble single prestage repeatedly 6 times
The whole valve flow gain adjustment of triplex redundance servo valve could be completed, debugging process complexity is cumbersome, and work efficiency is low.
The content of the invention
Present invention solves the technical problem that：For the prior art, triplex redundance servo valve need to assemble and disassemble single prestage repeatedly 6 times
It could complete the whole valve flow gain adjustment of triplex redundance servo valve, there is provided a kind of triplex redundance servo valve quickly fills demagnetizing method, can
Single prestage flow gain is quickly adjusted by the mutually isolated frock of space magnetic field on the premise of prestage is not dismantled.
The technical solution adopted by the present invention：
A kind of triplex redundance servo valve quickly fills demagnetizing method, comprises the following steps：
Step 1: the whole valve of triplex redundance servo valve is installed on testboard, it is preposition comprising 2# prestages, 3# prestages, 1#
Level；
Step 2: 2# prestages are carried out to fill demagnetization adjustment flow gain；
Step 3: record demagnetization voltage after the demagnetization of 2# prestages, draws no load discharge curve, calculate 2# prestages flow and increase
Benefit；
Step 4: successively 1# prestages and 3# prestages are carried out filling demagnetization and flow gain meter according to the method for step 3
Calculate.
The step 2 concretely comprises the following steps：Space magnetic field isolation frock is positioned on housing, space magnetic field isolation work
The middle square groove of dress passes through 2# prestages, makes 2# prestages and 1# prestages, 3# is preposition isolates frock positioned at space magnetic field respectively
Both sides, by coil be positioned over space magnetic field isolation frock on first magnetize to saturation state, then demagnetize to operating point；
The space magnetic field isolation frock includes the upper working plate being fixedly connected and lower working plate, upper working plate and lower frock
Plate has middle square groove；Upper frock plate material is magnetic material 1J50, for magnetic conduction；Lower frock plate material is hard aluminium alloy
2A12, for improving permeability by bright annealing heat treatment mode every magnetic, upper plate.
The space magnetic field isolation frock top magnetic flux forms closed circuit via upper working plate；Played with working plate at present
Separated magnetic effect, avoids space magnetic field influence 1# prestages and 3# preposition.
In the step 4, ensure that 1# prestages and 3# prestages flow gain should be consistent with 2# prestages.
Beneficial effects of the present invention：
Original to fill demagnetizing method, filling demagnetization process needs being dismounted for multiple times prestage, and efficiency is low, and the present invention can reduce dismounting time
Number, shortens servo valve debugging, rework time, improves efficiency；Space magnetic field phase can be passed through on the premise of prestage is not dismantled
Mutually isolation frock quickly adjusts single prestage flow gain.
