Embodiment
It is following that the present invention is described in detail with reference to accompanying drawing:
As shown in Figure 1, the present invention is a kind of on-line Full oil filter, is made up of two filters, it comprises cylindrical shell 2, at the top of cylindrical shell 2 vent valve 1 is housed, and hypersober 3 and filter core 5 are housed in the inside of cylindrical shell 1, hypersober 3 is an activated alumina, and filter core 5 is made up of glass fibre.Side at cylindrical shell 2 is equipped with pressure gauge valve 4, at opposite side Pressure gauge 19 is installed.The valve seat 8 of electromagnetically operated valve 7 is provided with three fuel feed holes 10 and three oil outlets 9, is connected with three on load tap changeres simultaneously so that can realize an oil filter.Oil inlet pipe 13 1 ends are connected with oil-feed 10, and the other end is connected with cylindrical shell 2 by inlet valve 18, and coarse filter 11 and pump 12 are housed respectively on oil inlet pipe 13, and coarse filter 11 is made up of the copper mesh filter core.Flowline 14 1 ends are connected with oil-out 9, and the other end is connected with cylindrical shell 2 with oil return valve 6 by delivery valve 15 respectively, and PLC controller 17 is controlled by 16 pairs of pumps 12 of holding wire.
Shown in Fig. 2,3, circuit theory of the present invention and control circuit, it is by N (zero line), L, L, L
