Abstract
The utility model relates to a high precision peristaltic pump, which consists of a peristaltic pump head and a stepper motor, wherein the peristaltic pump head is assembled with the stepper motor into a whole, and the peristaltic pump head consists of a shell, a transmission wheel assembly, a roller, a conveying pipe and a screw hole; the roller is arranged on the central position of the transmission wheel assembly, trolleys which can roll freely are arranged at the same distance to each other on the periphery of the transmission wheel assembly, one side surface of the conveying pipe is attached to the inner wall of the shell, the other side surface is attached to the trolley, the shell is provided with four screw holes, screws can pass through the screw hole to be fixedly connected with the stepper motor so as to prevent the swinging of the peristaltic pump head in the work, and the conveying pipe is of a Teflon rubber pipe and has the advantages of strong acid-alkali resistance, high temperature resistance, aging prevention, long service life and the like. The high precision peristaltic pump has the advantages of simple structure, correct measurement, pressure resistance and the like, and has great application value for the high precision analysis instrument in the fields such as medicine, chemical engineering, environmental protection and the like.
Description
Technical field:
The utility model relates to a kind of pump, relates in particular to a kind of for matching used peristaltic pumps of highi degree of accuracy microanalyser device such as medicine, chemical industry, environmental protection.
Technical background:
At medicine, chemical industry, the high accuracy analysis appliance requires configuration peristaltic pump in fields such as environmental protection is realized the conveying and the metering of material, present peristaltic pump is mainly by housing, speed-adjustable motor, transmit wheels, roller bearing, roller, transport tube is formed, wherein delivery wheel group switching centre position is provided with a roller bearing, but be provided with the free rolling roller in the equidistant position of transmission wheels periphery, transmit wheels and inner walls and have the gap, transport tube passes the gap, one side and inner walls are fitted, another side and roller are fitted, speed-adjustable motor drives roller bearing and rotates, and then drive transmits the rotation of wheels periphery roller, extruding transport tube when roller rotates, make the material of transport tube one end be drawn, under the roller drainage, material flows out from the transport tube the other end.So constantly circulate, reach the purpose of conveying material.
Existing peristaltic pump mainly contains following shortcoming: at first, peristaltic pump mainly is applicable to the high precision micro field of analytic instrument, adopts speed-adjustable motor to drive the roller bearing rotation, only can adjust the rotational speed of roller bearing, can not adjust the angle of swing of roller bearing, not reach more accurate metering effect; Secondly, existing transport tube is mainly elastic hose, because of transport tube and inner walls constantly produce friction, makes it to wear and tear easily pressurized, reduces working life, increase operation cost of enterprises.
Summary of the invention:
The utility model provides a kind of highi degree of accuracy peristaltic pump at the deficiencies in the prior art.
For realizing above purpose, the technical solution adopted in the utility model is:
A kind of highi degree of accuracy peristaltic pump is made up of Wriggling Pump Head and stepper motor, and wherein Wriggling Pump Head and stepper motor are installed and be combined into one.
Described Wriggling Pump Head is made up of housing, transmission wheels, roller bearing, roller, transport tube, screw hole; Wherein delivery wheel group switching centre position is provided with a roller bearing, but be provided with the free rolling roller in the equidistant position of transmission wheels periphery, transport tube one side and inner walls applying, another side and roller are fitted, housing is provided with four screw holes, utilize screw to pass screw hole and stepper motor is fixed, avoid Wriggling Pump Head can not swing at work.
Described stepper motor and roller bearing are installed as one, and stepper motor drives roller bearing and rotates, and then drive the rotation of transmission wheels periphery roller.
Described transport tube is the Teflon sebific duct, has advantages such as strong acid-base resistance, high temperature resistant, anti-aging, long service life.
The utility model mainly solves following technical problem: (1) adopts stepper motor to replace speed-adjustable motor, the rotational speed of can regulate roller bearing not only, and the angle of swing that can also regulate roller bearing reaches more accurate metering effect; (2) transport tube adopts the Teflon sebific duct to replace elastic hose, has strong acid-base resistance, advantage such as high temperature resistant, wear-resistant, anti-aging, increases transport tube working life; (3) housing is provided with four screw holes, utilizes screw to pass screw hole and stepper motor is fixed, and avoids Wriggling Pump Head can not swing at work, increases steadiness.
Description of drawings:
Fig. 1 is the utility model Wriggling Pump Head plan view.
Fig. 2 is the utility model Wriggling Pump Head rear view.
Fig. 3 is the whole construction profile of the utility model.
Embodiment:
As shown in Figure 3, a kind of highi degree of accuracy peristaltic pump is made up of Wriggling Pump Head 1 and stepper motor 2, and wherein Wriggling Pump Head 1 is installed with stepper motor 2 and is combined into one.
As shown in Figure 1 and Figure 2, Wriggling Pump Head 1 is made up of housing 11, transmission wheels 12, roller bearing 13, roller 14, transport tube 15, screw hole 16.
During concrete enforcement, utilizing screw can pass tighten up a screw hole 16 of Wriggling Pump Head 1 fixes with stepper motor 2, transport tube 15 passes the gap of housing 11 inwalls and roller 14 formation, transport tube 15 1 sides and housing 11 inwalls are fitted, another side and roller 14 are fitted, and two ends are fixed, stepper motor 2 is connected combination with roller bearing 13, stepper motor 2 drives roller bearing 13 and rotates, and then driving 12 peripheral rollers 14 rotations of transmission wheels, extruding transport tube 15 makes the material of transport tube 15 1 ends be drawn when roller 14 rotations, under roller 13 drainage, material flows out from transport tube 15 the other ends, so constantly circulates, and reaches the purpose of conveying material.
The utlity model has advantages such as simple in structure, accurate measurement, anti-crushing resistance, the high accuracy analysis instrument in fields such as medicine, chemical industry, environmental protection has very big use value.
