Abstract

The utility model discloses a micro pump for pipe which is a pipe pump which the pressure is low, and the flow rate is small but the regulating range thereof is large. A flexible hose (3) pressed by a roller (7) is the structural principle of the micro pump for pipe. The air in the pipe is extruded to form vacuum, the fluid conveyed in requirement is sucked in from the entrance (E), then the fluid is pressed by the roller (7), at last the fluid is discharged from the exit (F), so the fluid is conveyed from on point to the other point. When the flow rate is small, the fluid of number species in different natures and flow rates can be conveyed by a plurality of roots of pipes which the utility model can load simultaneously. When the fluid with corrosivity or hypertoxicity is conveyed, the pump and surrounding instruments can not be corroded, the environment can also not be polluted, and the direction of the fluid when conveying can be transformed optionally at any moment.

Description

Micropump for pipe

The utility model is that a kind of pressure is very low, flow is very little, and flow adjustment range very big the pipe pump.

Existing centrifugal pump, sliding vane pump, gear pump, axial-flow pump, plunger pump, screw pump, rotor pump, diaphragm pump etc., be unsuitable under low-pressure, low discharge situation, working, and it is very little to the regulation range high flow capacity by low discharge, if in the time of often will changing conveying fluid of different nature with same pump, often to spend long period washery pump system, very inconvenient.And pollute surrounding environment (especially harmful gas and liquid, fluid that corrosivity is strong) thus easily.Have many pumps not reverse, when will carry several fluid of different nature simultaneously in same place the time, just must adopt several pump works, handling like this might inconvenience, even is difficult to accomplish.

The purpose of this utility model is to provide a kind of liquid or gas carried under low-pressure, per minute is by 9000～0.09Cm ³The pipe micro flow pump of (milliliter).This direction that can frequently change conveyance fluid can be carried multiple fluid of different nature simultaneously under low discharge, and carries the fluid that severe toxicity and severe corrosive are arranged, and can not pollute environment.

The utility model is with micro motor 5, and two (or more than two) rollers, 7 extruding that drive dress on the rotor 4 are contained in the flexible pipe 3 in the pump housing 2, inner air tube is extruded and is formed vacuum.The fluid that needs to carry is sucked from inlet, be squeezed to outlet by roller again then and discharge, rotor ceaselessly rotates, and goes round and begins again.Fluid is transported to another place by a place.The utlity model has following characteristics:

1, not only can under very low flow, work, and the changes in flow rate regulation range is very big, can reach more than 100,000 times.

2, when low discharge is worked, can promptly in a pump, can carry out the fluid delivery operation of several heterogeneitys and different flow simultaneously with the several flexible pipe work of fashionable dress.

When 3, carrying the fluid of another kind of character, only need to change a flexible pipe,, change simple, convenient and rapid without any component of washery pump by the fluid conversion of carrying a kind of character.

4, during conveyance fluid, in the flexible pipe of airtight situation, carry out fully, can not pollute surrounding environment, especially more suitable to harmful fluid (severe toxicity and severe corrosive).

5, the direction of conveyance fluid conversion arbitrarily at any time.

6, simple in structure, make easily, easy to carry, can be placed on Anywhere and work.Concrete structure of the present utility model reaches embodiment with reference to the accompanying drawings and is described as follows:

Fig. 1 is the utility model and is furnished with a complete set of electric component and the sectional arrangement drawing of chest 7.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the longitudinal section enlarged view of rotor 4.

Micro motor 5(Fig. 1) drive the rotor 4(Fig. 1 and 2 that is contained on it), and two rollers 7 are housed on the rotor 4.Two slotted holes are arranged at the pump housing 2 tops, and the two ends of flexible pipe 3 reach outside the pump in two slotted holes thus.End cap 1 pump housing 2 is screwed on the chest 6, and micro motor 5 also is fixed on 6.Like this, pump all is fixed on micro motor and becomes as a whole on the chest.When the axle of micro motor 5 rotates, rotor 4 is in company with rotation, roller 7 just pushes the flexible pipe 3 that is attached on the pump housing 2 inwalls continuously, air in the pipe is extruded the formation vacuum, the fluid that needs to carry sucks from inlet E, be expressed to outlet F by roller again then and discharge, so fluid is just sucked by the E place continuously and flows out from F.If with the conversion of micro motor sense of rotation, then the fluid of Shu Songing just flows into and is discharged by the E place from F.The structure of rotor 4 (Fig. 3) is to clamp two rollers 7 at the two ends of two connecting plates 11, bearing 8, inner spacing collar 10, outer separator 14 and packing ring 9 are housed in it, and with tubule 13 as the double rivets of axle, be riveted on 11, the rotor shell 12 that is fixed on 5 of the micro motors also is with 4 fine steel tube 13(Fig. 2) be riveted on 11.

Claims

1, a kind of low pressure low discharge and the very big pipe pump of flow adjustment range, its structure mainly are made up of the pump housing 2, flexible pipe 3, similar oval-shaped rotor 4, micro motor 5 and the chest 6 of likeness in form peltate.And the pump housing 2 and micro motor 5 all are screwed on chest 6, and the two ends of flexible pipe 3 reach the semi-circumference that pump outer flexible tube middle part then is attached to pump housing inwall from two slotted holes in top of the pump housing 2 become " U " font.Rotor 4 is contained in the rotating shaft of micro motor 5, it is characterized in that: conveyance fluid is with roller 7 squeezing tube 3 on the inwall of the pump housing 2, inner air tube is extruded and formed vacuum, the fluid that needs to carry is sucked from inlet E, pushed by roller 7 again then and discharge, fluid is transported to the other end by an end of pipe by outlet F.

2, pipe pump according to claim 1, it is characterized in that: rotor 4 is that the two ends with two similar oval-shaped connecting plates 11 clamp two rollers 7, and bearing 8, inner spacing collar 10, outer separator 14 and packing ring 9 are housed in the roller 7, and, be riveted on 11 with the double rivet of fine steel tube 13 conduct axles.
