Description
Technical field
The invention belongs to liquid pump technical fields, and in particular to the determination method of the safe handling duration of wriggling pump hose,
Device and peristaltic pump.
Background technique
In the prior art, peristaltic pump includes driver, pump head and hose, and fluid is isolated in hose, by pump head
Swivelling idler sequence squeezing tube, so that hose is wriggled, realize the transmission of liquid.Peristaltic pump has Ke Kuaisugenghuan hose, stream
The features such as body can drive in the wrong direction, can do operating, be pollution-free, easy cleaning is safeguarded, is widely used in chemical industry, metallurgy, papermaking, food, stone
The industries such as oil, pharmacy.
As shown in Figure 1, peristaltic pump includes driver (not shown), pump head 101 and elastic hose 102.When wriggling pump work,
Hydraulically full 103 in elastic hose 102, the idler wheel 104 in pump head 101 is driven to rotate by shaft 108 by driver, idler wheel
Multiple rollers 105 on 104 peripheries are in idler wheel rotation process successively alternately in hose briquetting 106 underneath towards hose briquetting
106 squeeze elastic hose 102, and after roller 105 leaves the lower zone of hose briquetting 106, it is soft that roller 105 no longer squeezes elasticity
Thus pipe 102 forms negative pressure to discharge elastic hose 102 in elastic hose 102, pump liquid 103.
According to use demand, elastic hose allows for restoring shape rapidly after radially compressed, and to have certain
Wearability and bearing capacity.The elastic hose of different peristaltic pump adaptations has accordingly using duration, wriggling pump work to phase
Answer and just need more elastic hose when duration, otherwise elastic hose may be caused to rupture, liquid then from hose rainwater in puddles go out flow into pump head
Idler wheel in, cause equipment fault and damage.
Since elastic hose belongs to easily-consumed products, can not be produced and sold with peristaltic pump.The bullet of current peristaltic pump
Property hose safe handling duration to be usually all hose manufacturer wriggle according to the model of elastic hose, material and combining
What the standard condition of pump was recommended, for example, safe handling duration of the elastic hose A under 600 revs/min, the operating conditions of 3 rollers is 36
Hour, safe handling duration of the elastic hose A under the operating condition of 300 revs/min, 3 rollers is 72 hours.But in peristaltic pump
In practical work process, peristaltic pump is not to be rotated with constant rotational speed, for example, it may be in preceding 10 hours with 600 revs/min
The revolving speed of clock rotates, and is rotated in the time below with other revolving speed, although this results in there are elastic hoses in different works
Safe handling duration under condition, but due to when an elastic hose uses in peristaltic pump operating condition change, still can not be quasi-
Really determine when replace the elastic hose on current peristaltic pump.
