Abstract
The invention discloses a vacuum pump air intake filter. According to the air intake filter, symmetrical gaps are reserved in the periphery of the same circle center in a filtering shell, a filter element is arranged, the center of a plug at one end of the filtering shell stretches out towards the outer end to form a sensor connector, the other end opening of the filtering shell is provided with a connection flange through a bolt and an elastic pad, the connection flange is fixedly provided with a flange cover through a sealing ring, the center of the flange cover stretches out towards the outer end to form an air outlet opening connector, and the peripheral outer wall of the filtering shell is provided with two air inlet connectors. According to the vacuum pump air intake filter, the air intake filter replaces a filter screen, the air intake quality is greatly improved, wear to a rotor is lowered, impurities are prevented from blocking a valve, and the service life of a vacuum pump is prolonged.
Description
Technical field:
The present invention relates to filtration, particularly a kind of filter cleaner being applicable to that air-inlet of vacuum pump is installed and used.
Background technique:
At present, air-inlet of vacuum pump is not generally all equipped with filtrating equipment, although other vacuum pump individual is equipped with filter screen, can not prevents impurity from entering in the pump housing completely, cause the wearing and tearing of pump internal rotor or the stuck of valve, affect the working life of rotor.
Summary of the invention:
The object of this invention is to provide a kind ofly effectively can improve air mass, the wearing and tearing that reduce pump internal rotor and prevent the vacuum pump air intake filter that valve is stuck, increase the service life.
Technological scheme of the present invention completes as follows, a kind of vacuum pump air intake filter, it comprises air intake filter is that concentric periphery reserves symmetrical gap and is provided with a filter core in a filter housing, it is characterized in that: be extended with a sensor connector outward at the plug center, one end of filter housing, filter housing another port is provided with an adpting flange with screw and cushion, adpting flange is mounted with a blind flange through seal ring, stretch out outward at the center of blind flange and an air outlet joint is installed, the outer circumferential walls of filter housing is provided with two air inlet connections.Install to external chiasma in 45 ° between two air input joints.
Compared with prior art the present invention has following beneficial effect: the present invention's air intake filter replaces filter screen, substantially increases air mass, reduces the wearing and tearing of rotor, prevents the stuck valve of impurity, extends the working life of vacuum pump.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention; Fig. 2 is surface structure schematic diagram of the present invention.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, air intake filter of the present invention is that concentric periphery reserves symmetrical gap and is provided with a filter core 4 in a filter housing 2, a sensor connector 1 is extended with outward at the plug center, one end of filter housing, filter housing another port is provided with an adpting flange 6 with screw and cushion 5, adpting flange is mounted with a blind flange 8 through seal ring, stretch out outward at the center of blind flange and an air outlet joint 9 is installed, the outer circumferential walls of filter housing is provided with two air inlet connections 3.Install to external chiasma in 45 ° between two air input joints.So both can save space, suction tude can be made again neatly to arrange.The filter layer of filter core adopts high-strength stainless steel wire.Can Reusability after filter gauze cleaning.
