Description
Technical field
The utility model relates to ring flange technical field more particularly to a kind of vacuum pump connecting flanges.
Background technique
Vacuum pump, which refers to, to be obtained using machinery, physics, chemically or physically chemical method to being evacuated by pumping container
The device or equipment of vacuum.For popular, vacuum pump is to improve, generate and maintain true in a certain enclosure space with various methods
Empty device.By the working principle of vacuum pump, vacuum pump can substantially be divided into two types, i.e. gas trapping pump and gas passes
Defeated pump.It is widely used in the industries such as metallurgy, chemical industry, food, electronics plated film.
And flange part is a kind of more commonly used design of part, it can preferably link together mechanical equipment.Method
Orchid connection or bump joint, refer to and are connected with each other by flange, gasket and bolt three as the removable of one group of combined sealing structure
Connection.Pipe flange is meant with effective flange in plumbing installation, with the inlet and outlet flange for meaning equipment in equipment.On flange
Perforation, bolt are close to two flanges.In vacuum pump mechanical equipment, needed in the flange part of these location applications toward contact
Connection other structures cooperate to ensure the fastness connected, and ensure the connection sealing of connecting shaft, need to lubricate some
Bearing arrangement in also need individually placed lubrication system to be lubricated, these mechanical equipments number of parts in an assembling process
Compare more, operates more complicated.General flange part all only plays simple connection function, is unable to satisfy mechanical structure
The leakproofness or lubricating requirement needed.
Utility model content
That in view of the above problems, the object of the present invention is to provide a kind of sealing performances is excellent, meets mechanical structure lubrication
It is required that vacuum pump connecting flange.
The utility model solves technical solution used by above-mentioned technical problem: a kind of vacuum pump connecting flange, including
Flange main body, the flange main body upper end center position are equipped with elliptical cylinder-shape and are linked and packed body, and the flange main body is equipped with and wears
The mounting hole of saturating flange main body, the mounting hole centre are equipped with connector, are equipped with several ventholes around the body that is linked and packed,
The flange main body is equipped with several lubrication grooves, and the volume surrounding that is linked and packed is equipped with seal washer.
Further, the flange main body is equipped with several connecting holes.
Further, the connection hole number is at least four.
Further, the inside of the lubrication groove is communicated with mounting hole.
Further, the seal washer material is rubber.
Utility model has the advantages that
The utility model, can be to the connection bearing for needing lubrication system by the way that several lubrication grooves are arranged in flange main body
Preferably connection and lubricant effect are played, keeps equipment more safe and reliable when in use, equipment is more convenient in assembling process
Fast, the compactness of connection is more preferable, connects in use stronger；It, can by the way that seal washer is arranged in the volume surrounding that is linked and packed
Meet the leakproofness of mechanical structure needs.
Detailed description of the invention
