Abstract
A cam bi-rotor pump comprises two cam rotors, seal rings, a rotor box, gear press covers and the like, wherein the two cam rotors are of synchronous moving structures and carry out transmission by a pair of external synchronous gear boxes, a transmission shaft drives the rotors to reversely rotate, the seal rings are arranged on the upper faces and the lower faces of the cam rotors which are made of nickel based alloy and can be provided with joints, a processing center of each cam rotor is made of curves, no stagnation point is arranged inside a rotor chamber, CIP online cleaning is automatically realized, and connecting shafts are integrally assembled. The cam bi-rotor pump has the advantages of easy maintenance and cleaning, wear resistance, corrosion resistance, compact and beautiful structure and long service life.
Description
Technical field:
The utility model relates to a kind of positive displacement feedway, and especially with two rotors that are synchronized with the movement, rotor carries out synchronous opposite spin under the drive of transmission shaft, constituted degree of vacuum and discharge pressure, finishes conveying.
Background technique:
Extensive use centrifugal rotor pump in industries such as petrochemical industry, fine chemistry industry, daily-use chemical industry, pharmacy, food, environmental protection, papermaking, coating, metallurgy, regular meeting causes in the occasion of some improper use centrifugal rotor pumps and has selected this pump for use.And its output flow is out of contior, descends along with the increase of resistance, necessary first full of liquid before running; Rotating speed is very high, is transferred material and is subjected to powerful bump and action of centrifugal force, often produces the phenomenon that the material composition differs, and the quality of finished product is descended, and causes expensively to enterprise, also wastes resource simultaneously.
The model utility content:
Existing rotor pump exists not enough in application.The utility model provides a kind of cam birotor pump, and it is made up of cam follower, seal ring, rotor casing, gear gland etc.
The technological scheme that its technical problem that solves the utility model adopts is: two cam followers are the structures that are synchronized with the movement, and carry out transmission by a pair of external synchronous gear box, and transmission shaft drives and carries out synchronous opposite spin; The cam follower top and bottom are provided with seal ring, and rotor is made with nickel-base alloy, but mounting interface, and machining center is made with curve, does not have the stationary point in the rotor chamber; The automation of CIP on-line cleaning is made, the shaft coupling overall package.
The beneficial effects of the utility model are: have the maintenance of being easy to and cleaning, wear-resistant, corrosion-resistant, compact structure is attractive in appearance, long service life.
Description of drawings
Fig. 1 is the product structure schematic representation.
Among the figure, 1, cam follower 2, seal ring 3, the pump housing 4, base 5, gear-box 6, bearing gland
Embodiment
With two cam followers that are synchronized with the movement 1, install towards the other side side by side; Cam follower 1 upper and lower settings seal ring 2 prevents that material from entering driving mechanism; Cam follower 1 is made by nickel-base alloy, and raising is resistance to worn, and the pump housing 3 is made by whole 316L stainless steel, and internal surface polishes; Base 4 and gear-box 5 are coupled together, then the length live axle is packed in the gear-box 5, again oil sealing is put into bearing gland 6, and bearing gland 6 is pressed in the gear-box 5, use bolt, carry out transmission by a pair of external synchronous gear box, cam follower 1 carries out synchronous opposite spin under the drive of transmission shaft; Can increase thermal insulation apparatus at the pump housing 3 according to user's needs; Clip interface, threaded coupling, the flange-interface of all existing international standards can be provided; Machining center uses Curve Machining, and making does not have the stationary point in the rotor chamber; Automatic structure with CIP online (on the spot) cleaning; The shaft coupling overall package, stainless steel outer packed, bright finishing avoids being coated with originally coming off of cream mopping.
