Its useful life.Oil filter should be strong with filtering ability, and circulating resistance is small, the performance such as service life length.General lube system
The cleaner of the middle several different filtering abilities of dress --- collecting filter, coarse filter and fine cleaner, main oil is arranged in parallel or in series in respectively
In road.(that is connected with main oil gallery is full flow filter, and lubricating oil is all through cleaner filtering when engine works；Therewith simultaneously
Connection is bleeder type filter).Wherein coarse filter one is connected in main oil gallery, is full flow type；Fine cleaner is connected in parallel in main oil gallery,
For shunting.Collecting filter and a full-flow oil filter are generally provided only with modern car engine.Coarse filter filters out machine
Particle diameter is more than 0.05mm impurity in oil, and fine cleaner is then used for filtering out the fine impurities that particle diameter is more than 0.001mm.On the market
Oil filter, two big shortcomings be present, and new product compensate for shortcoming, it is therefore necessary to use the strong magnetic oil filtration of new product
Device.The existing oil filter used, permanent filtration is not all had to the impurity more than or less than its paper filter element micropore,
The impurity that those can only be equal to paper filter element micropore and be mounted in paper filter element micropore play it is permanent filter out effect, therefore filter
It is clear extremely inefficient.
Utility model content
The technical problems to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of screw air compressing machine oil mistake
Filter device.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of screw air compressing machine oil filter of the utility model, including upper lid, strong magnetic filtering core and paper filter core, it is described on

Matter filter core inner ring bottom is provided with pull bar, and the pull bar lower end is connected with supporting plate, tie-rod sealing circle, filter core pressure in turn from bottom to up
Tight spring, holddown spring packing ring and cartridge seal circle, the upper lid inside is provided with ball valve, and the ball valve upper end is connected with bypass
Valve spring, the case of by-pass valve upper end are connected with valve seat.
Preferably, the ball valve lower end is provided with the passage connected with the housing interior volume.
Preferably, it is provided with body seal circle between the upper lid and the shell.
Preferably, seal washer is provided between the valve seat and the upper lid.
Preferably, the upper end of the pull bar is connected with nut, and nut seal is provided between the nut and the upper lid
Packing ring.
Preferably, the upper lid is provided with inlet and outlet.
The beneficial effect that the utility model is reached is：Two filter cores are provided with the screw air compressing machine oil filter,
Wherein, strong magnetic filtering core has very strong attraction to metal, so can effectively filter out the metal fragment in machine oil, and papery is filtered
Core can then filter out the nonmetallic disintegrating slag in machine oil, and the machine oil under double filtration then can largely improve the work of machine oil
State, and by-passing valve is provided with the screw air compressing machine oil filter, it is excessively sticky in machine oil and paper filter core can not be passed through
In the case of, machine oil then can by pressure open ball valve directly export, it is worth mentioning at this point that, it is this in particular cases, machine oil is
Make also first pass through strong magnetic filtering core by paper filter core and filter out the metal fragment in machine oil, and then reduce machine oil
Harmful effect.
