Abstract
The utility model relates to a hose pump, which is mainly used for the transportation of flowing material. The utility model is formed by that a plurality of vacuum-pumping attaching tubes 6 are arranged on the hose 2 of the ordinary hose pump; when a cam rotor 3 presses the hose 2 to move from an inlet position to an outlet position; material before a pressing point in the hose is discharged out of the hose 2; simultaneously, gas in the vacuum-pumping attaching tubes 6 can also be extruded out of a pump chamber along an outlet duct 8, thus the pump chamber 5 is in a vacuum state, producing negative pressure; owing to the existence of the negative pressure, the utility model can prompt the hose to be fully recovered, increasing the suction lift and the measuring accuracy of the pump, and reducing the mechanical fatigue of the hose.
Description
The utility model belongs to pump and already makes the field, is mainly used in the transportation of flowable materials.
Peristaltic pump belongs to a kind of novel mechanical of recently newly developing, it is to make rotor with a cam or similar device, adopt metal or plastics one class hard material to make shell, the flexible pipe of a rubber-like is set between rotor and the shell, have rotor one rotation of cam, just oppress the flexible pipe distortion, outside the material excavationg pump before the pressure point; Pressured some deformation recovery that the back flexible pipe produces simultaneously is in the material suction pump with the ingress.Indoor unlubricated dose of common this peristaltic pump, the suction capactity of pump restore by the elastic strain of flexible pipe self fully adopts decision, thereby the suction journey of pump is low, and flexible pipe abrasion heating is big, and hose life is short; In addition, because the elastic strain of flexible pipe self is repeatedly after tens times, elastic force will be affected, and the single suction journey descends, and the measuring accuracy of pump also will descend.
The utility model purpose is to provide a kind of and carries high suction depth and measuring accuracy, reduction flexible pipe mechanical fatigue, reduces the peristaltic pump that hose life was denuded and generated heat, improve to flexible pipe.
Structure of the present utility model is made up of rotor 3, pump interface 4, the pump chamber 5 of pump casing 1, flexible pipe 2, strap cam, it is characterized in that pump interface 4 is to be with mechanical seal, and pump chamber 5 is airtight, and is full of oiling agent.(or not establishing) 1～50 is set on the flexible pipe 2 vacuumizes attached pipe 6, the entry conductor 7 that is provided with respective numbers in the ingress that vacuumizes attached pipe 6 links with pump chamber, and the delivery channel 8 that is provided with respective numbers in the outlet port that vacuumizes attached pipe 6 is linked to outside the pump chamber.
When cam follower 3 is pushed down flexible pipe 2 when the outlet port is shifted in the ingress, material before the pressure point in the flexible pipe is discharged from outside the flexible pipe 2, in being provided with the device that vacuumizes attached pipe 6, the gas that vacuumizes simultaneously in the attached pipe 6 also is forced out outside the pump chamber along delivery channel 8, make pump chamber 5 become vacuum state, produce negative pressure; Flexible pipe behind the pressure point produces deformation and restores under the negative pressure double action of the elastic recovery of flexible pipe self and pump chamber, thus the suction that produces with material by in the suction pump of ingress.Because the existence of negative pressure can impel flexible pipe fully to restore, improve the suction journey and the measuring accuracy of pump, reduced the mechanical fatigue of flexible pipe; Because pump chamber has adopted the mode of mechanical seal, be convenient to add oiling agent simultaneously, the lubrication of performance oiling agent has reduced abrasion and heating.
Advantage of the present utility model is that flexible pipe 2 can both fully restore at every turn, has improved suction journey and measuring accuracy, has reduced utmost point tool fatigue, simultaneously because the adding of lubricant oil has reduced wearing and tearing and heating, the working life of having improved flexible pipe.
Accompanying drawing 1 is a kind of sectional drawing of peristaltic pump.
Accompanying drawing 2 is flexible pipe sectional views that have the attached pipe of vacuum of difformity, varying number.
Accompanying drawing 3 is not to be with the flexible pipe sectional view that vacuumizes attached pipe.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, structure of the present utility model by rotor 3, pump interface 4, the pump chamber 5 of pump casing 1, flexible pipe 2, strap cam, vacuumize attached pipe 6, entry conductor 7, delivery channel 8 and form.Entry conductor 7 one terminations vacuumize attached pipe 6, one ends and pump chamber links.Delivery channel 8 one ends are linked to outside the pump chamber, and pump interface 4 is to be with mechanical seal, and pump chamber 5 is airtight, and is full of oiling agent.
Shown in the accompanying drawing 2-1 be have an attached pipe of vacuum, the circular hose sectional view.
Shown in the accompanying drawing 2-2 be have six attached pipes of vacuum, the circular hose sectional view.
Shown in the accompanying drawing 2-3 be have an attached pipe of vacuum, convex flexible pipe sectional view.
Shown in the accompanying drawing 2-4 be have eight attached pipes of vacuum, convex flexible pipe sectional view.
Shown in the accompanying drawing 3 is the flexible pipe sectional view of not being with the attached pipe of vacuum.
