Abstract
The invention relates to a novel vacuum sampling pump. The pump comprises a motor, a sampling chamber and an anechoic chamber; the anechoic chamber is arranged between the motor and the sampling chamber; a bracket is arranged at the outside of the anechoic chamber; a front end cap, a rear end cap and an external cover are arranged at the outside of the sampling chamber; an air inlet, an air outlet and a rotor are arranged in the inner part of the sampling chamber; an inner cavity of the rotor is provided with a groove, the groove is internally embedded with a graphite flake, and the inner cavity of the rotor is an eccentric structure; the inner part of the anechoic chamber is provided with a shaft coupling and silica gel; a center shaft of the rotor and main shaft of the motor are connected by the shaft coupling. The graphite flakes move in the inner cavity of the rotor, the rear parts of graphite flakes generate negative pressure, so that the pump is used for measuring gas flow rate and negative pressure.
Description
Technical field
The invention belongs to machinery manufacturing technology field, be specifically related to a kind of novel evacuated sampling pump.
Background technology
Along with economic quick growth, economic development constantly carries out, environmental pollution is sustainable existence also, people are more and more higher to the requirement of environment, in order to be convenient for people to the monitoring to environment, the detection of environment dust, dust prevention and control, gas flow rate measure serial product and increase gradually, but current equipment majority exists the defects such as noise is big, fault rate is high, structure is complicated.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is proposed that a kind of novel evacuated sampling pump, described sampling pump is provided with the graphite flake of special construction, when graphite flake moves in cylinder, graphite flake rear portion can produce negative pressure, and the present invention both may be used for measuring gas flow rate, it is also possible to is used for measuring negative pressure.
The technical scheme is that a kind of novel evacuated sampling pump, including motor, sampler chamber and anechoic chamber, described anechoic chamber is between motor and sampler chamber, described anechoic chamber is provided externally with bracket, head end lid is included outside described sampler chamber, rear end cap and overcoat, air inlet it is provided with inside sampler chamber, gas outlet and rotor, inner chamber at rotor is provided with groove, it is embedded with graphite flake at groove, the inner chamber of rotor is eccentric structure, shaft coupling and silica gel it is provided with in the inside of described anechoic chamber, the main shaft of the central shaft of described rotor and described motor is linked together by shaft coupling.
Described overcoat is between head end lid and rear end cap.
Together with described bracket is bolted on the shell of motor.
Described rear end cap is fixed together by bolt and bracket.
There is advantages that
When the graphite flake of the present invention moves in the inner chamber of rotor, graphite flake rear portion can produce negative pressure, and the present invention both may be used for measuring gas flow rate, it is also possible to is used for measuring negative pressure.
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is present configuration schematic diagram.
Fig. 2 is rotor cross section structure schematic diagram of the present invention.
In figure, 1, blind nut；2, bearing；3, rotor；4, head end lid；5, overcoat；6, rear end cap；7, bracket；8, graphite flake；9, shaft coupling；10, silica gel；11, motor；12, air inlet；13, gas outlet.
Detailed description of the invention:
nullReferring to shown in Fig. 1 and Fig. 2，The present invention includes motor 11、Sampler chamber and anechoic chamber，Described anechoic chamber is between motor 11 and sampler chamber，Described anechoic chamber is provided externally with bracket 7，Head end lid 4 is included outside described sampler chamber、Rear end cap 6 and overcoat 5，Rotor 3 it is provided with inside sampler chamber，Inner chamber at rotor 3 is provided with groove，Three graphite flakes 8 have been embedded in it at groove，Graphite flake 8 can freely skid off in rotor 3，Shaft coupling 9 and silica gel 10 it is provided with in the inside of described anechoic chamber，The central shaft of described rotor 3 is linked together by shaft coupling 9 with the main shaft of described motor，Silica gel 10 can make the main shaft of motor 11 and the central shaft of rotor 3 be tightly connected，Described overcoat 5 is between head end lid 4 and rear end cap 6，And be bolted on together，Together with described bracket 7 is bolted on the shell of motor 11.Described rear end cap 6 is fixed together by bolt and bracket 7.Being provided with blind nut 1 in the front portion of head end lid 4, be provided with bearing 2 inside blind nut 1, the central shaft of described bearing 2 and described rotor 3 is fixed together.Air inlet 12 and gas outlet 13 it is provided with in sampler chamber.The inner chamber of rotor 3 is eccentric structure, is the work space of graphite flake 8.Operationally, motor 11 rotor driven 3 rotates the present invention, and graphite flake 8 under the influence of centrifugal force, outwards flies out, and scrapes air-flow to outlet.Move and so forth so that air-flow flows to outlet from import continually.When graphite flake 8 moves in the sampler chamber inner chamber of rotor 3, graphite flake 8 rear portion can produce negative pressure.Therefore, the present invention both may be used for measuring gas flow rate, it is also possible to is used for measuring negative pressure.
