Embodiment
Below in conjunction with accompanying drawing, through the more detailed explanation of description the utility model to mode of execution.
As shown in Figure 1; This online oil filtration circulation means; Comprise hydraulic mechanism clutch release slave cylinder 10, and the hydraulic mechanism fuel tank 8 that is arranged on hydraulic mechanism clutch release slave cylinder 10 tops, hydraulic mechanism fuel tank 8 is communicated with oil pump 1 through pipeline; Oil pump 1 connects relief valve 3, one-way valve 2 and oil filter 4 successively through pipeline; The export pipeline of oil filter 4 is communicated with the fuel tank that has level control 6, and fuel tank 6 delivery outlets that have level control are communicated with the hydraulic mechanism oil pump 9 that is arranged on hydraulic mechanism clutch release slave cylinder 10 belows through pipe-line system 7, constitute an oil strain circulation loop system.
In addition, oil filter 4 is designed with oil spill pipe 12 and warning device, and relief valve 3 is connected with said hydraulic mechanism fuel tank 8 through spill pipe 12.Because filter core or pipeline stop up build-up of pressure when surpassing setting pressure, oil filter 4 promptly can be reported to the police and reduced system pressures through oil spill pipe 12 when oil-way system.
On the oil pump 1 of this device, be connected with Oil pump electrical machinery 11, Oil pump electrical machinery 11 links to each other with system alarming device 13.Warning device 13 is made up of pressure transducer and warning light, and warning light lights when oily filtering system stops up, and at this moment, needs the parts of oily filtering system are overhauled replacing.
The operator scheme of this device hydraulic mechanism is taked intermittent operation; So this device guarantees the fuel tank of hydraulic mechanism and the fuel tank of oil filter and remains an amount of hydraulic oil, with prevent because of air entering fuel sucking pipe causes the oil pump of oil filter can't proper functioning.The fuel tank of realization hydraulic mechanism and the fuel tank of oil filter are possessed an amount of hydraulic oil all the time and are realized through following design: the hydraulic oil consumption of confirming and inject hydraulic mechanism and oil filter whole system; Level controller 5 of design in the fuel tank that has level control 6 of oil filter, level controller 5 links to each other with system power supply and warning device 13; When the liquid level of hydraulic oil in the fuel tank that has level control 6 was lower than setting value, system sent the signal of oil pump 1 work, and Oil pump electrical machinery 11 starts; Otherwise when the liquid level of hydraulic oil in the fuel tank that has level control 6 was higher than setting value, system sent oil pump 1 stop signal, and Oil pump electrical machinery 11 shuts down.
As shown in Figure 2, oil filter 4 is provided with the double-filtration fuel tank, is respectively one-level inlet box 14 and secondary inlet box 15; Said one-level inlet box 14 filter screen density are 10 μ m, and secondary inlet box 15 filter screen density are 5 μ m, and the oil strain amount is 30 liters/minute.In this oil filter 4, also be respectively arranged with filler opening 16, flow-off 17 and return opening 18.Designed the high pressurized overflow protection facility of flow-off 17 for this device, wherein, high pressurized overflow protection destroys oil pump by the high-pressure and hydraulic oil of avoiding discharging in the hydraulic mechanism operation and is designed with the oil filter.During high pressurized overflow protection work, high pressure oil is flowed out by flow-off 17.When oil pressure adhered to specification in the device, high pressure excess flow protection device flow-off 17 was closed, and avoided hydraulic oil loss in the oil pump, and causing can't oil suction.
And this device can be taked manually or automated manner control, and manual mode is controlled to be through regulating time relay control oil pump work and the stop time that this device is installed; Automated manner is the oil pump continuous firing.
The working principle of the utility model is: the oil circuit of hydraulic mechanism clutch release slave cylinder 10 is communicated with through the oil circuit of oil pipe and filtrating equipment; The fuel tank 6 that the oil pump 1 of filtration system is extracted the fluid in the hydraulic mechanism fuel tank 8 out and injection oil filter 4 has the level control function after clean filtering; Hydraulic oil in this fuel tank after clean filtering is the oil sources of hydraulic mechanism oil pump 9, makes the closed loop of a circulating filtration of oil-way system formation of hydraulic mechanism and oil filter.
At first with the oil circuit of oil filter 4 and hydraulic mechanism clutch release slave cylinder 10 together with; Oil pump electrical machinery 11 startups when oil filter 4; Drive oil pump 1 hydraulic oil in the hydraulic mechanism fuel tank 8 is extracted out, and filter through the filter core of oil filter 4, the hydraulic oil after the purification is admitted to the fuel tank 6 that has level control; When the hydraulic oil liquid level in the fuel tank that has level control 6 reaches setting height; Oil pump electrical machinery 11 shuts down, and the hydraulic oil liquid level of the utility model hydraulic mechanism fuel tank 8 is higher than the filler opening of hydraulic mechanism oil pump 9 in the design, so there is the hydraulic oil after the purification to give hydraulic mechanism oil pump 1 altogether all the time; When hydraulic mechanism Oil pump electrical machinery 11 starts hydraulic oil is pumped in the hydraulic mechanism clutch release slave cylinder 10; Hydraulic oil liquid level in the external fuel tank 6 that has a level control will descend; When liquid level drops to certain position; The control system that has in the fuel tank 6 of level control restarts the Oil pump electrical machinery in the filtrating equipment 11, thereby realizes the fluid of the hydraulic mechanism in the test is carried out online circulating filtration.
