When interior carry out dipping lacquer；
Plate after drying is packed into impregnating vessel by the 4th step, cover is closed, then open the vacuum pumping valve on impregnating vessel, to leaching
Paint can vacuumizes, and the pressure value of the vacuum meter on impregnating vessel is made to reach -0.096MPa or more, closes vacuum pumping valve；
5th step opens the liquid feed valve of impregnating vessel, and the insulated paint that temperature is 35-40 DEG C is injected into the impregnating vessel of vacuum, until
Paint solution face in impregnating vessel there was not 100~200mm of plate top surface, was kept for 40 minutes, opens the pressure relief valve on impregnating vessel, makes
Vacuum is released in impregnating vessel；
6th step opens cover, is successively shaken in impregnating vessel by clamping piece and close cover after each plate；
7th step opens the intake valve of impregnating vessel, and the pressure value of the pressure gauge on impregnating vessel is made to reach 0.3~0.4MPa, keeps
Carry out pressurization dipping lacquer within 15 minutes；
8th step, opens the pressure relief valve of impregnating vessel, and the release of impregnating vessel high pressure opens cover, takes out each plate and dried
Solidifying paint, wipes paint tumor off after drying；
9th step is that each plate repeats to brush 3-5 all over insulated paint with brush, dries；
The plate dried after coagulating paint is laid in flat car, flat car is pushed into drying oven, furnace together with each plate together by the tenth step
130 DEG C, drying time 90-150 minutes of temperature；
11st step, according to assembling demand, respectively insulated pull rod (3), front shroud (5), back shroud (6), left limit plate (7),
Right limit plate (8) and touching ferropexy plate (9) suitable position auger shell pit；
Left and right limit plate and touching ferropexy plate (9) are fixed between forward and backward cover board by the 12nd step by insulating screw；
13rd step, the fixed gear shift terminal (2) on insulated pull rod (3), and inserted from insulating slide bottom by insulated pull rod (3)
Enter；
14th step, in two pieces of touching ferropexy plate (9) upper fixing end sub- connecting members (1), and respectively by each group terminal-connecting element (1)
It is connect with the tap of high-voltage booster；
15th step, each element after assembling is in addition to needing conductive position, brushing hydrophobic silicon rubber.
10. the production method of high pressure gear shift magnetic switch according to claim 9, which is characterized in that the 6th step executed
Journey are as follows:
Cover is opened, plate is clamped in insulated paint by clamping piece and is shaken back and forth, slosh frequency is maintained at 35-55 beats/min, often
Block plate jitter time is 25-45 seconds, keeps plate to submerge in insulated paint completely always during shaking.
