Abstract
The utility model relates to a locking device of peristaltic pump, characterized in that the two sides of a pump wheel is symmetrically provided with two pressure belts, the outer side of the pressure belt is separately provided with a clamping device applying force to the pressure belt, and accordingly, the utility model can not only prevent a middle crankshaft from suffering from deflective force, but also eliminate the defect that the pressure belts are convex upward. The locking device of peristaltic pump provided by the utility model is characterized in simple structure, and convenient pump pipe replacement, and the pump pipes are oppositely arranged on the two sides of the pump wheel. Therefore, the work efficiency of the entire peristaltic pump is further improved. Because the clamping device applies elastic compression force, the flow of the pump can be even more steadier.
Description
The utility model relates to a kind of locking device of peristaltic pump.
Peristaltic pump is widely used in all kinds of flowrate measuring tools, and its locking device has many kinds of forms, and wherein modal have three kinds of gland type, press belt type and compressing tablet formulas.The mode that gland type compresses pump line is fixed, nonelastic buffering, and therefore to the pump line serious wear, monolateral gland type is because to the unidirectional vertical application of force of pump shaft, so pump shaft is damaged because of eccentric wear; The compressing tablet formula compress mode and gland type is similar, so also have above-mentioned shortcoming; Press belt type is advanced at present mode, has spring on its tension structure, and the elastic force direction moves towards identical with pressure zone, and its biggest advantage is the stressed substantially constant of pump motor, so flow is more steady, it is also less to the wearing and tearing of pump line, but its major defect is:
1, monolateral pressure zone, pump motor axle are subjected to vertical power partially, thereby axle is easy to wear;
2, when pressure zone is metal tape, grow it and can upwards heave service time one, thereby can't compress pump line, and influence is used; When pressure zone is plastic tape, though can solve the problem of heaving, can increase the pump line friction, can increase the weight of the pump motor load on the one hand, also can shorten the pump line life-span on the other hand, especially when plastic tape wears out, this problem is more serious when being clamminess.
The purpose of this utility model is to propose a kind of new locking device, and it can solve the existing existing deficiency of locking device.The impacting force symmetry of this locking device is applied on the pump motor axle, so axle is not subjected to inclined to one side power; In addition, because application of force direction is vertical with metal push belt, so metal tape can upwards not heaved again.
Accompanying drawing 1 is the front view of the locking device that the utility model proposes, and accompanying drawing 2 is that hold down gag is partly faced (analysing and observe) figure in this locking device, and accompanying drawing 3 is pump line card full views.The structure of this locking device is described in detail in detail below.
As shown in Figure 1,1 is pump impeller, and 2 is roller, and 11 is pump line, and it places on pump impeller 1 periphery.The locking device that the utility model proposes is characterised in that pressure zone 5,6 symmetries are placed on pump impeller 1 both sides, outside the pressure zone 5,6 movable holddown 7, the 8 perpendicular contacts that have elastic force in the hold down gag 17,16 is arranged respectively, and the elastic force direction is perpendicular to pressure zone.Like this, when two pump lines, 11 symmetries after between pump impeller 1 periphery and the pressure zone 5,6, pump impeller 1 rotates, roller 2 constantly upwards pushes up movable holddown 7,8 springy, thereby pump line 11 is extruded again and again, liquid is wriggled forward in the pipe.In this process, owing to 7,8 whiles of movable holddown, in opposite directions to pump impeller 1 application of force, and the Changing Pattern of application of force size is also consistent, so the pump motor axle can not be subjected to inclined to one side power; In addition, because the elastic force of movable holddown vertically acts on pressure zone, so pressure zone can not press tightly pump line because of heaving again.At this, pressure zone 5,6 preferably adopts metal sheet band.The elastic force of movable holddown 8,7 can be supplied with (elastic force of movable holddown is supplied with by spring 9,10 among Fig. 1) by the elastomer of spring, spring sheet or rubber and so in the hold down gag 16,17.
Consider that for different thicknesses the pump line of different elasticity and varying number need apply different these requirements of big or small impacting force, the elastic force of movable holddown should be adjustable in the hold down gag, designs hold down gag as shown in Figure 2 for this reason.As shown in Figure 2, spring 9 is between movable holddown 7 and adjusting screw 14, and the three places the coating part 15 that has internal thread jointly, like this, can change the elastic force of spring 9 by adjusting screw 14, thereby changes the pressure of 7 pairs of pressure zones of movable holddown.In order to install, change the convenience of pump line 11, the pump line card 3 of trough of belt, 4(are as shown in Figure 3 in the middle of also can comprising in this locking device), pressure zone 5,6 is fixed on the pump line card 3,4 by screw 12,13 and 18,19 respectively, and pump line 11 places the pipe clamp groove.
As seen by above-mentioned, the locking device structure of the peristaltic pump that the utility model proposes is simple, and it is convenient to change pump line; It is to the pump impeller symmetry application of force, so the pump motor axle can not be subjected to inclined to one side power; Its application of force direction is perpendicular to pressure zone, so pressure zone can not heaved; It lays pump line in opposite directions on the pump impeller both sides, so whole peristaltic pump working efficiency more improves; Because what hold down gag applied is elastic pressure, so can make the flow of pump more stable.
Claims (2)
1, a kind of locking device of peristaltic pump is characterized in that:
Pressure zone 5,6 symmetries are placed on pump impeller 1 both sides, and pressure zone 5,6 is outer movable holddown 7,8 perpendicular contacts perpendicular to the elastic force of pressure zone of having in the hold down gag 17,16 respectively.
2, the locking device of peristaltic pump according to claim 1, it is characterized in that: hold down gag comprises spring 9, movable holddown 7, adjusting screw 14 and coating part 15, spring 9 is between movable holddown 7 and adjusting screw 14, and the three places the coating part 15 that has internal thread jointly.
