Abstract
The utility model discloses a peristaltic pump, which comprises a pump head, a motor, safety coupler and a frequency converter, wherein the motor is provided with a motor shaft, and the frequency converter is connected with the motor. A half portion of the safety coupler is connected with the motor shaft, and the other half portion of the safety coupler is connected with the pump head. The peristaltic pump has the advantages of adopting the motor to directly drive the pump head, using the frequency converter for regulating speed, being stable and reliable and strong in power, being capable of saving energy resources and coating agents and being simple in operation.
Description
Technical field
The utility model relates to a kind of pump, is a kind of specifically and the matching used peristaltic pump of dressing machine.
Background technique
Peristaltic pump is by hocket extruding and discharge pumping fluid of the elasticity delivery hose to pump, as with two finger pinching flexible pipes, along with moving of finger, forms negative pressure in the pipe, and liquid is mobile thereupon.Motor is to drive pump head work indirectly in the existing peristaltic pump.The medicine that has in medicine trade need carry out dressing; often be with peristaltic pump and the supporting use of dressing machine; but because delivery flow rate is bigger; burn motor through regular meeting; thereby increased cost of production; and the also bad control of flow of the transmission that is in operation, make that the dressing up-to-standard rate is low, thereby wasted coating agent.
The model utility content
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of simple to operate, steadily reliable, power is strong, the peristaltic pump that can save the energy and coating agent.
Technological scheme: in order to solve the problems of the technologies described above, a kind of peristaltic pump described in the utility model, comprise pump head and the motor that has motor shaft, described peristaltic pump also comprises safety coupling, the frequency variator that links to each other with motor, and half part of described safety coupling is joined with motor shaft, second half part links to each other with pump head.
Have keyway on described pump head, described safety coupling links to each other with pump head by key.
The utility model will be originally controlled pump head work indirectly by motor and is changed into by motor and directly drive pump head work, frequency variator is according to the rotational velocity of the big or small automatic control motor axle of delivery flow rate, thereby the extruded velocity of control pump head, operation is also simple like this, is substantially need not manage after opening.
Beneficial effect: compared with prior art, the utility model has the advantages that and adopt motor directly to drive pump head, use frequency converter timing, steadily reliably, power is strong, and can save the energy and coating agent; Simple to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of A portion among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of peristaltic pump described in the utility model, comprise pump head 1, motor 3, safety coupling 4 and frequency variator 5, motor 3 is provided with motor shaft 2, frequency variator 5 links to each other with motor 3, half part of safety coupling 4 is enclosed within on the motor shaft 2 and by key and is fixed on the motor shaft 2, has keyway on pump head 1, and second half part of safety coupling 4 links to each other with pump head 1 by key.
During use, open motor, regulate the rotational velocity of motor shaft by frequency variator, the speed of frequency variator can be regulated automatically according to the size of delivery flow rate, motor shaft drives the coupling rotation then, and coupling drives pump head work again, thereby has realized that motor directly drives pump head work.
The above only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
