Description

There is the peristaltic pump of heat abstractor

Technical field

The utility model relates to peristaltic pump structure, especially a kind of peristaltic pump with heat abstractor.

Background technology

Peristaltic pump, also known as peristaltic pump, is a kind of positive displacement pump, completes material conveying by the change of sealed volume.Transmission Device drives two pressure rollers in 180 ° of distributions on rotor continuously to roll along pump case inner flexible tube, flattens sebific duct, certainly Under the elastic positive action with side deflector roll of body, pipe restores to the original state, and now produces high vacuum in pipe and material is sucked tube chamber, entrance Intraluminal fluid is discharged under thing followed pressure roller effect in pipe.So circulation, material constantly sucks and discharges.Soft Tube pump has a characteristic that and can carry high concentration high viscosity liquid；Accurate measurement can be carried out, easy to adjust；Good seal, without letting out Leakage；Simple in construction, failure rate is low；Flow and power adjustable, save energy consumption.Flexible pipe is the critical component of peristaltic pump, is also rapid wear Part, it mainly had fatigability destruction, lancinating destruction, explosion destruction etc. at the reason that lose efficacy.The prevention of flexible pipe premature failure is arranged Execute a variety of, as optimized pipeline structure, reduced unnecessary elbow, valve as far as possible, periodically remove in-tube fouling, suitably reduce The rotating speed of pump, periodic replacement flexible pipe position etc..

Pump has different flows under different rotating speeds, and temperature is higher, and shaft power is lower, and pump discharge is lower.So peristaltic pump Radiating condition affect operating efficiency.Use temperature≤100 DEG C of conventional hoses, it is considered in operating process, moving component produces heat Amount, is generally used for the operating mode of temperature of charge≤80 DEG C.If temperature of charge is more than 80 DEG C, hose strength is decreased obviously.Extruding piston shoes Must have good lubrication with the contact surface of flexible pipe, lubricating oil temperature is less than 80 DEG C.

The heat radiation of peristaltic pump is presently mainly by improved structure, and the piston shoes of squeezing tube on rotating disk transform as bearing rolling Built-in flexible pipe is changed into external by dynamic formula roller, uses the lubricating oil etc. of particular design, improves heat radiation effect to a certain extent Really, extending the service life of flexible pipe, but structure being complicated, production cost is expensive, and later maintenance expense is also higher.
