Embodiment
A kind of coal winning machine hydraulic oil as shown in Figure 1 forces filtrating equipment, comprises coal winning machine hydraulic oil container 1, oil pump 4, the first filter 2, the second filter 7, oil suction line 3, oil feeding line 6 and oil return circuit 11, one end of described oil suction line 3 is connected with coal winning machine hydraulic oil container 1, the other end of described oil suction line 3 is connected with the input end of oil pump 4, described the first filter 2 is arranged on described oil suction line 3, the output terminal of described oil pump 4 is connected with one end of oil feeding line 6, the other end of described oil feeding line 6 is connected with the oil inlet P of heighten valve or break 8, described the second filter 7 is arranged on oil feeding line 6, on described oil feeding line 6 and between described the second filter 7 and oil pump 4, be connected with overflow oil circuit 10, described overflow oil circuit 10 is connected with coal winning machine hydraulic oil container 1, on described overflow oil circuit 10, be provided with relief valve 9.
When use, pump motor 5 drives oil pump 4 to work, hydraulic oil in coal winning machine hydraulic oil container 1 enters oil pump 4 through oil suction line 3, oil pump 4 is pumped to hydraulic oil the oil inlet P of heighten valve or break 8 by oil feeding line 6, hydraulic oil filters through the first filter 2 and the second filter 7 in the process of carrying, the oil return inlet T of heighten valve or break 8 is connected with coal winning machine hydraulic oil container 1 by oil return circuit 11, on described oil return circuit 11, cooler 12 is installed.In actual use, in the time polluting fluid and cause the second filter 7 and stop up, because the second filter 7 is without bypass valve arrangement, pollute fluid and cannot enter heighten valve or break 8, the high pressure oil that oil pump 4 produces directly returns to coal winning machine hydraulic oil container 1 by relief valve 9 and overflow oil circuit 10, thereby ensures that heighten valve or break 8 can not damage because of oil contamination.When the improvement of this system is to ensure to pollute fluid and cannot enters heighten valve or break 8, well solve again oil pump 4 problem of damaging that builds the pressure, in actual use, in the time that operator find that coal-mining machine hydraulic system cannot normally be worked, only can solve fault by the filter core of changing the second filter 7.This hydraulic oil forces filtrating equipment to carry out forced filtration to the fluid that enters the hydraulic element such as heighten valve or break 8, fundamentally ensure the turbidity test of work fluid, thereby ensure the normal work of the hydraulic element such as heighten valve or break 8, in the time of system cisco unity malfunction, only need dimension to change fine filter cartridge.Thereby greatly reduce the time of coal winning machine down-hole maintenance, reduced fault ratio of hydraulic pressure system.
