In the existing absolute oil fuel charger; Though can the many pollutions of filtering, still some pollutants is residual gets off and gets in the hydraulic efficiency pressure system, thereby hydraulic efficiency pressure system is caused chance failure; And existing absolute oil fuel charger volume ratio is bigger, and filter efficiency is lower.
The utility model content
The purpose of the utility model provides a kind of accurate absolute oil fuel charger, and fresh oil is through the filtration of this hierarchical, and the solid impurities that contains in the oil is cut off in filtering effectively; Effectively reduce rate of breakdown with oily mechanical equipment; Improved filter efficiency, and flow is big, volume is little; The compact conformation of complete machine, the life-span is long.
The accurate absolute oil fuel charger that the utility model provides, comprise to oil carry out filter just primary filter, be used for the secondary filter device of the tiny solid impurities of filtering and oil be delivered to the oil pump of secondary filter device from primary filter;
Further, said secondary filter device comprises accurate filter I and the accurate filter II that is communicated with successively;
Further, said oil pump delivery port is provided with the pressure controller of control secondary filter device input hydraulic pressure;
Further, said oil pump delivery port is provided with the overflow safety valve;
Further, said pressure controller is connected between said oil pump delivery port and the said overflow safety valve;
Further, said overflow safety valve delivery port is connected to the delivery port of said accurate filter II;
Further, said accurate filter I is provided with pressure-detecting device I, and said accurate filter II is provided with pressure-detecting device II;
Further, said primary filter input port is provided with the valve of control oil-feed.
The beneficial effect of the utility model is: get into said accurate absolute oil fuel charger as fresh oil, at first through primary filter fresh oil is filtered for the first time, filter the back through oil pump input accurate filter I and get into accurate filter II; Through the filtration of hierarchical, can actv. filtering oil the pollutants of the inside, reduce rate of breakdown effectively with oil machinery; And said accurate absolute oil fuel charger flow is big, compact integral structure, and volume is little; Be easy to move, and the life-span is long.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Fig. 1 is the structural representation of the utility model; As shown in the figure; Accurate absolute oil fuel charger described in the present embodiment comprise to oil carry out filter just primary filter 2, be used for the secondary filter device 4 of the tiny solid impurities of filtering and oil be delivered to the oil pump 3 of secondary filter device 4 from primary filter 2; Said primary filter 2 input ports are provided with oil-feed by-pass valve control 1; Said primary filter 2 delivery ports are connected with oil pump 3 input ports, and 2 pairs of oil of said primary filter filter for the first time, the bigger solid impurities of volume in the filtering oil.
In the present embodiment; Said secondary filter device 4 comprises accurate filter I9 and the accurate filter II10 that is connected; Pump into said accurate filter I9 through the said primary filter 2 first oil that filter through said oil pump 3; The delivery port of said oil pump 3 is connected with said accurate filter I9 input port, also is provided with pressure-detecting device I7 on the said accurate filter I9, and said pressure-detecting device I7 is in order to detect the hydraulic pressure value of oil among the accurate filter I9; Also be provided with pressure-detecting device II8 on the said accurate filter II10; Said pressure-detecting device II8 is in order to detect the hydraulic pressure value of said accurate filter II10 the inside oil, and the oil that the process that described secondary filter device is carried oil pump 3 is just filtered filters the fine impurities that contains in the filtering oil once more.
In the present embodiment; Said oil pump 3 delivery ports are connected with the input port of said secondary filter device 4; The delivery port of said oil pump 3 is provided with the pressure controller 6 of the input hydraulic pressure of control secondary filter device 4, and the delivery port of said oil pump 3 also is provided with overflow safety valve 5, and said pressure controller 6 is connected between the delivery port and overflow safety valve 5 of said oil pump 3; Said overflow safety valve 5 outlets are connected to the delivery port of said accurate filter II10; When system's oil mass is excessive, pass through overflow safety valve 5 through the part of the first oil of filtering and flow out, the safe pressure of said overflow safety valve 5 is made as the high 10%--15% of settling pressure than said accurate absolute oil dispenser system.
In the present embodiment; The fresh oil that contains pollutants gets in the said accurate absolute oil fuel charger; At first filter for the first time through primary filter device 4, the solid impurities that the filtering oil volume is bigger, said oil pump 3 is being input in the said secondary filter device 4 through the first oil that filters; Accurate filter I9 in said secondary filter device 4 enters into said accurate filter II10 after filtering again; The tiny solid impurity of said secondary filter device 4 in can filtering oil is not contained the oil of solid impurities, has therefore reduced the fault with oily mechanical equipment.
