Working principle of the present utility model is as follows:
Operating fork car travels to oil suction station, and makes forklift door frame lifting tilt forward and back motion repeatedly.
The banking motion of forklift door frame lifting is handled by the first plate valve in fork truck and the second plate valve, hydraulic oil tank of forklift can be driven, solid grain contamination in soiling solution force feed can be made to mix through repeatedly tilting action, when carrying out follow-up oil suction operation, solid grain contamination can be carried with hydraulic oil, reduce solid grain contamination remaining in hydraulic oil tank of forklift, improve filtering effect.
Start oil absorption machine and carry out oil suction operation to hydraulic oil tank of forklift, by truck hydraulic oil inspiration slop tank, the truck hydraulic oil sucked in slop tank is delivered in canister, then is delivered to absolute oil tank after being filtered by oil filter one after oil filter two filters.
When oil suction operates, observe the level meter on slop tank, when the hydraulic oil oil level in level meter display slop tank be raised to the highest liquid level time, the spool of manual tune three-way valve group two, be communicated with slop tank, pipeline between oil filter two and canister successively, in oil filter two oil pump effect under, the hydraulic oil in slop tank is delivered in canister.When the hydraulic oil oil level in slop tank drops to minimum liquid level, then regulating three-way valve group two turns off the pipeline between slop tank and oil filter two, now canister is communicated with the inlet/outlet of oil filter two, and oil filter two can carry out circulating oil filtering operation to the hydraulic oil in oil filter.
After oil suction has operated, fork truck being travelled to refueling station, having used oilling machine to carry out refueling operation to hydraulic oil tank of forklift, the hydraulic oil after filtering in absolute oil tank has been added in hydraulic oil tank of forklift.
When carrying out refueling operation, need equally to observe the level meter on absolute oil tank, when in absolute oil tank, hydraulic oil liquid potential drop is to minimum liquid level, the spool of regulating three-way valve group one, be communicated with absolute oil tank, pipeline between oil filter one and canister successively, will be delivered in absolute oil tank after the filtration of the hydraulic oil stored in canister oil machine one after filtration; When the hydraulic oil oil level of absolute oil tank be raised to the highest liquid level time, turn off the pipeline between absolute oil tank and oil filter one, now canister is communicated with the inlet/outlet of oil filter one, and oil filter one can carry out circulating oil filtering operation to the hydraulic oil in canister.
To in truck hydraulic oil filtration process, when carrying out refueling operation, the liquid level of canister may drop to minimum liquid level, now by regulating three-way valve group two, be communicated with slop tank, pipeline between oil filter two and canister successively, hydraulic oil in slop tank is delivered in canister after oil filter two filters, for the hydraulic oil in supplementary canister.And when carrying out oil suction operation, the liquid level of canister may be raised to the highest liquid level, by regulating three-way valve group two, turn off the pipeline between slop tank and oil filter two.
Before first time uses, in order to ensure that absolute oil tank has enough clean hydraulic oil all the time, need to carry out pre-filtration step.This pre-filtration step is, before step one, hydraulic oil is injected canister, and turn off oil strain unit and the pipeline between slop tank and absolute oil tank respectively, now canister is all communicated with the import and export of oil filter two with the import and export of oil filter one, oil strain unit carries out pre-filtering operation to the hydraulic oil in canister, pre-filtering is after ten minutes, be communicated with the pipeline between oil filter one and absolute oil tank again, clean hydraulic oil is injected absolute oil tank.
The above mode of execution is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
