On the upper and lower pump housing of what general sampling pump had be arranged on pump housing seat top, all there are inlet hole and the air outlet hole of coaxial line, the inlet hole port of upper pump casing is provided with air-intake valve plate, the air outlet hole port of lower pump body is provided with the valve block of giving vent to anger, plane type elastomer diaphragm is pressed between lower pump body and pump housing seat, drive between the bent axle, connecting rod of motion of membrane and have miniature bearing, drive motor is direct current micromotor.What also have is directly fixing by cylinder body and fixed base, and air inlet and give vent to anger and cannot adjust causes the efficiency of sampling pump on the low side, and maintenance is larger.
Summary of the invention
Technical problem to be solved in the utility model is to address the above problem, and the beam type that a kind of volume is little, efficiency is high gas samping pump is provided.
Described beam type gas samping pump, is characterized in that:
Comprise the motor and the gas samping pump that are combined as a whole; Described gas samping pump comprises pump rotor, eccentric adjustment piece, cylinder body and the housing with a pair of valve;
Described pump rotor is directly socketed in the rotating shaft of motor, in the rotating shaft of motor, is set with described eccentric adjustment piece by bearing;
The end face madial wall of described cylinder body motor one side and the outer side wall of described eccentric adjustment piece laminating suit, described cylinder body makes the eccentric axis of madial wall to described rotating shaft by the thickness even variation at cross section upper side wall.
The eccentric axis of the outer side wall of described eccentric adjustment piece to described rotating shaft.
The outer side wall of described eccentric adjustment piece is provided with outstanding positive stop key, is provided with the oval hole that embeds described positive stop key at the sidewall corresponding position of described cylinder body.
The sidewall of described cylinder body is provided with through hole, is provided with fastening screw in the fixed base exterior edge face of motor, for described cylinder body being threaded cylinder body is fixed with described fastening screw through fastening screw trip bolt from described through hole.
Described pump rotor is titanium alloy material.
The utility model becomes an entirety two partial design of drive motor and sampling pump, pump rotor is directly fixed on the axle of drive motor, after this changes, bring simple in structure, lightweight, vibrate the lot of advantages such as little, vibrate the little Concentric rotation basis that also makes pump rotor and cylinder body, sampling efficiency uprises.Alleviate weight, reduced cost of production.
The utility model has been realized the free adjustment to the cylinder body degree of eccentricity by the method two eccentric and Multi-point fastening of cylinder body and eccentric adjustment piece, eccentric adjustment piece has amplified the eccentric degree of cylinder body, greatly expand the eccentric adjustment range of cylinder body, sampling efficiency is significantly improved, and can in use keep, in the situation of valve invariant position, readjusting the degree of eccentricity of cylinder body.
In addition the material of pump rotor is also changed into titanium alloy material lightweight and that intensity is high by the ferrous metal of commonly using.
Brief description of the drawings
Fig. 1 is the utility model structural representation plan view,
Fig. 2 is A-A sectional view in Fig. 1.
In figure: 1-air chamber, 2-slide plate, 3-valve, 4-motor, 5-rotating shaft, 6-fixed base, 7-eccentric adjustment piece, 8-pump rotor, 9-cylinder body, 10-housing, 11-positive stop key.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated: as shown in Fig. 1,2, described beam type gas samping pump, comprises the motor 4 and the gas samping pump that are combined as a whole; Described gas samping pump comprises pump rotor 8, eccentric adjustment piece 7, cylinder body 9 and the housing with a pair of valve 3 10; Described pump rotor 8 is directly socketed in the rotating shaft 5 of motor 4, in the rotating shaft 5 of motor 4, is set with described eccentric adjustment piece 7 by bearing; The output shaft of motor is directly as the rotating shaft of pump rotor, save coupling, make the concentricity of rotating shaft less, the vibrations and the noise that bring significantly reduce, stretch out with cylinder body and contact in the time that pump rotor rotates because blade relies on centrifugal force, turn round and have great significance for gas sampling stably, the efficiency of sampling is improved.
The described cylinder body 9 end face madial walls of motor one side and the outer side wall of described eccentric adjustment piece 7 laminating suit, described cylinder body 9 makes the eccentric axis of madial wall to described rotating shaft 5 by the thickness even variation at cross section upper side wall.The inwall bias of cylinder body changes the volume of air chamber 1, plays the effect of transporting sample gas, and how effectively the variation of extended volume is an important ring that improves sampling efficiency here.Cylinder body of the present utility model can rotate and adjust to applicable angle before fixing, makes the maximizing efficiency of sampling.
Especially, the eccentric axis of the outer side wall of described eccentric adjustment piece 7 to described rotating shaft 5.Because cylinder body is sleeved on eccentric adjustment piece outside, the eccentric eccentric degree that has amplified cylinder body that changes of outer wall of eccentric adjustment piece, because the rotating speed of pump rotor is very high, make the degree of eccentricity of inboard wall of cylinder block itself impossible excessive, the utility model adopts eccentric adjustment piece, has greatly widened the adjustment range of cylinder body bias.
The outer side wall of described eccentric adjustment piece 7 is provided with outstanding positive stop key 11, is provided with the oval hole that embeds described positive stop key 11 at the sidewall corresponding position of described cylinder body 9.The sidewall of described cylinder body 9 is provided with through hole, is provided with fastening screw in fixed base 6 exterior edge faces of motor 4, for described cylinder body being threaded cylinder body is fixed with described fastening screw through fastening screw trip bolt from described through hole.The oval hole of cylinder body can change the angle of cylinder body within the specific limits, allows the fastening screw hole site of stationary housing on fixed base that multiple rear fixing are set, and in the time that cylinder body is adjusted to optimum position, can have corresponding fastening screw corresponding with the through hole of cylinder body.Therefore before installation, can first adjust eccentric adjustment piece according to air inlet nozzle and outlet nozzle position, determine after the angle of eccentric adjustment piece, then stationary housing, and can in use re-start adjustment.
