Description
Technical Field
The invention belongs to the technical field of liquid pumps, and particularly relates to a method and a device for determining safe use time of a peristaltic pump hose and a peristaltic pump.
Background
In the prior art, a peristaltic pump comprises a driver, a pump head and a hose, wherein a fluid is isolated in the hose, and the hose is sequentially pressed by a rotating roller on the pump head, so that the hose peristalses to realize the transmission of the liquid. The peristaltic pump has the characteristics of quick hose replacement, reversible fluid, dry running, no pollution, easy cleaning and maintenance and the like, and is widely applied to the industries of chemical industry, metallurgy, papermaking, food, petroleum, pharmacy and the like.
As shown in fig. 1, the peristaltic pump includes a driver (not shown), a pump head 101, and an elastic hose 102. When the peristaltic pump works, the elastic hose 102 is filled with the liquid 103, the roller 104 in the pump head 101 is driven to rotate by the driver through the shaft 108, the rollers 105 on the periphery of the roller 104 sequentially and alternately press the elastic hose 102 towards the hose pressing block 106 below the hose pressing block 106 during the rotation of the roller, and after the rollers 105 leave the area below the hose pressing block 106, the rollers 105 do not press the elastic hose 102 any more, so that the elastic hose 102 is released, the negative pressure is formed in the elastic hose 102, and the liquid 103 is pumped.
The elastic hose must be able to recover its shape rapidly after being radially compressed, and must have a certain resistance to wear and pressure, depending on the requirements of use. The elastic hose of different peristaltic pump adaptations all has corresponding use for a long time, and the peristaltic pump work needs more elastic hose when corresponding time is arrived, otherwise just can cause the elastic hose to break, and liquid then flows into in the gyro wheel of pump head from the hose ash, causes equipment trouble and damage.
The elastic hose is an easily-consumed product, so that the elastic hose can be produced and sold without a peristaltic pump. The safe use duration of the elastic hose for the existing peristaltic pump is generally recommended by a hose manufacturer according to the model and the material of the elastic hose and in combination with the standard working condition of the peristaltic pump, for example, the safe use duration of the elastic hose A under the working condition of 600 revolutions per minute and 3 rollers is 36 hours, and the safe use duration of the elastic hose A under the working condition of 300 revolutions per minute and 3 rollers is 72 hours. However, in the actual working process of the peristaltic pump, the peristaltic pump does not rotate at a constant rotation speed, for example, the peristaltic pump may rotate at a rotation speed of 600 rpm in the first 10 hours and rotate at another rotation speed in the later time, which results in that although the elastic hose is safely used under different working conditions, the working condition of the elastic hose is changed when the elastic hose is used in the peristaltic pump, and thus, it is still impossible to accurately determine when the elastic hose on the current peristaltic pump should be replaced.
