Abstract
The invention relates to a vacuum sampling pump unit. The vacuum sampling pump unit comprises a motor, a sampling chamber, and an anechoic chamber; the anechoic chamber is arranged between the motor and the sampling pump; a supporting frame is arranged outside the anechoic chamber; the exterior of the sampling chamber comprises a front end cover, a back end cover, and an outer sleeve; an air inlet, an air outlet, and a rotor are arranged in the sampling chamber; an inner chamber of the rotor is provided with a groove; graphite flakes are arranged in the groove via embedding; the inner chamber of the rotor is of an exocentric structure; a shaft coupling and a silica gel unit are arranged in the anechoic chamber; a center shaft of the rotor is connected with a main shaft of the rotor via the shaft coupling. When the graphite flakes move in the inner chamber of the rotor, negative pressure is generated at the back parts of the graphite flakes; and the vacuum sampling pump unit can be used for measuring gas flow rate and negative pressure.
Description
Technical field
The invention belongs to machinery manufacturing technology field, be specifically related to vacuum sampling pump device.
Background technology
Along with the quick growth of economy, economic development is constantly carried out, environmental pollution is sustainable existence also, the requirement of people to environment is more and more higher, conveniently people are to the monitoring of environment, the product that the detection of environment dust, dust prevention and control, gas flow rate measure series increases gradually, but current equipment majority exists defects such as noise is large, failure rate is high, complex structure.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, propose vacuum sampling pump device, 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 measurement gas flow velocity, can also be used for measuring negative pressure.
Technical scheme of the present invention is: vacuum sampling pump device, comprise motor, sampler chamber and anechoic chamber, described anechoic chamber is between motor and sampler chamber, the outside of described anechoic chamber is provided with bracket, described sampler chamber outside comprises head end lid, rear end cap and overcoat, air intake opening is provided with in sampler chamber inside, gas outlet and rotor, groove is provided with at the inner chamber of rotor, graphite flake is embedded with at groove, the inner chamber of rotor is eccentric structure, shaft coupling and silica gel is provided with in the inside of described anechoic chamber, the central shaft of described rotor and the main shaft of described motor are 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.
The present invention has following beneficial effect:
When 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 measurement gas flow velocity, can also be 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 structural representation of the present invention.
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 intake opening; 13, gas outlet.
Embodiment:
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, the outside of described anechoic chamber is provided with bracket 7, described sampler chamber outside comprises head end lid 4, rear end cap 6 and overcoat 5, rotor 3 is provided with in sampler chamber inside, groove is provided with at the inner chamber of rotor 3, three graphite flakes 8 have been embedded at groove, graphite flake 8 can freely skid off in rotor 3, shaft coupling 9 and silica gel 10 is provided with in the inside of described anechoic chamber, the central shaft of described rotor 3 and the main shaft of described motor are linked together by shaft coupling 9, silica gel 10 can make the central shaft of the main shaft of motor 11 and 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.Be provided with blind nut 1 in the front portion of head end lid 4, be provided with bearing 2 in blind nut 1 inside, described bearing 2 is fixed together with the central shaft of described rotor 3.Air intake opening 12 and gas outlet 13 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, and graphite flake 8 under the influence of centrifugal force, outwards flies out, and scrapes air-flow to outlet in the present invention.Move and so forth, make air-flow flow 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 measurement gas flow velocity, can also be used for measuring negative pressure.
