Abstract
The present invention relates to a kind of graphite sampling pump, including motor, sampler chamber and anechoic chamber, the anechoic chamber is between motor and sampler chamber, the outside of the anechoic chamber is provided with bracket, the sampler chamber outside includes head end lid, rear end cap and overcoat, air inlet, gas outlet and rotor are provided with inside sampler chamber, groove is provided with the inner chamber of rotor, graphite flake is embedded with groove, the inner chamber of rotor is eccentric structure, shaft coupling and silica gel are provided with the inside of the anechoic chamber, the central shaft of the rotor is linked together with the main shaft of the motor by shaft coupling.When graphite flake of the invention is moved in the inner chamber of rotor, graphite flake rear portion can produce negative pressure, both can be used for measuring gas flow rate, can be also used for measuring negative pressure.
Description
Technical field
The invention belongs to machinery manufacturing technology field, and in particular to a kind of graphite sampling pump.
Background technology
With economic rapid growth, economic development is constantly carried out, environmental pollution is also persistently present, requirement more and more higher of the people to environment, monitoring of the people to environment for convenience, the detection of environment dust, dust prevention and control, gas flow rate determine serial product gradually to be increased, but current equipment majority has the defects such as noise big, fault rate is high, complex structure.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of graphite sampling pump, the sampling pump is provided with the graphite flake of special construction, when graphite flake is moved in cylinder, graphite flake rear portion can produce negative pressure, the present invention both to can be used for measuring gas flow rate, can be also used for measuring negative pressure.
The technical scheme is that：A kind of graphite sampling pump, including motor, sampler chamber and anechoic chamber, the anechoic chamber is between motor and sampler chamber, the outside of the anechoic chamber is provided with bracket, the sampler chamber outside includes head end lid, rear end cap and overcoat, air inlet, gas outlet and rotor are provided with inside sampler chamber, groove is provided with the inner chamber of rotor, graphite flake is embedded with groove, the inner chamber of rotor is eccentric structure, shaft coupling and silica gel are provided with the inside of the anechoic chamber, the central shaft of the rotor is linked together with the main shaft of the motor by shaft coupling.
The overcoat is located between head end lid and rear end cap.
The shell of the bracket and motor is bolted on together.
The rear end cap is fixed together by bolt with bracket.
The present invention has the advantages that：
When graphite flake of the invention is moved in the inner chamber of rotor, graphite flake rear portion can produce negative pressure, the present invention both to can be used for measuring gas flow rate, can be also used for measuring negative pressure.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention.
Fig. 2 is rotor cross section structure schematic diagram of the present invention.
In figure, 1, blind nut；2nd, bearing；3rd, rotor；4th, head end lid；5th, overcoat；6th, rear end cap；7th, bracket；8th, graphite flake；9th, shaft coupling；10th, silica gel；11st, motor；12nd, air inlet；13rd, gas outlet.
Specific embodiment：
Referring to shown in Fig. 1 and Fig. 2,The present invention includes motor 11,Sampler chamber and anechoic chamber,The anechoic chamber is between motor 11 and sampler chamber,The outside of the anechoic chamber is provided with bracket 7,The sampler chamber outside includes head end lid 4,Rear end cap 6 and overcoat 5,Rotor 3 is provided with inside sampler chamber,Groove is provided with the inner chamber of rotor 3,Three graphite flakes 8 have been embedded in groove,Graphite flake 8 can be skidded off freely in rotor 3,Shaft coupling 9 and silica gel 10 are provided with the inside of the anechoic chamber,The central shaft of the rotor 3 is linked together with the main shaft of the motor by shaft coupling 9,Silica gel 10 can be tightly connected the main shaft of motor 11 and the central shaft of rotor 3,The overcoat 5 is located between head end lid 4 and rear end cap 6,And be bolted on together,The shell of the bracket 7 and motor 11 is bolted on together.The rear end cap 6 is fixed together by bolt with bracket 7.Blind nut 1 is provided with the front portion of head end lid 4, bearing 2 is provided with inside blind nut 1, the bearing 2 is fixed together with the central shaft of the rotor 3.Air inlet 12 and gas outlet 13 are provided with sampler chamber.The inner chamber of rotor 3 is eccentric structure, is the working space of graphite flake 8.Operationally, the rotor driven 3 of motor 11 is rotated the present invention, and graphite flake 8 under the influence of centrifugal force, is outwards flown out, and air-flow is scraped to outlet.And so on move so that air-flow is continually flowed to from import and exported.When graphite flake 8 is moved in the sampler chamber inner chamber of rotor 3, the rear portion of graphite flake 8 can produce negative pressure.Therefore, the present invention both can be used for measuring gas flow rate, can be also used for measuring negative pressure.
