Abstract
The utility model relates to a double-cavity high concentration material rotor pump, which is mainly composed of a belt pulley, a pump shaft, an end cover, a partition board, two pump casing bodies, two pairs of gears which are engaged inside and outside, two rotors, two eccentric cams, two balance blocks, a protective cover, a bearing, and keys, etc. The working principle of the utility model is that when the rotors are rotated in the pump casing bodies, a volume which is enclosed by the rotors, the pump casing bodies, the end cover, and the partition board can be changed to generate the functions of sucking and discharging to high concentration materials. Because the utility model adopts two cavities to work, the inner parts of all centrifugal forces are balanced. The utility model adopts the left and the right balance blocks to balance unbalanced moments, and therefore, when the pump works, the operation is stable without vibration, and the flow rate is big.
Description
(1) technical field
The utility model belongs to the pump field, relates to a kind of two-chamber high concentration material rotor pump.
(2) background technique
China's high concentration material rotor pump commonly used has Bicorn rotator pump, double-arc impeller pump and single chamber high concentration sludge rotor pump etc. at present.The basic principle of Bicorn rotator pump and double-arc impeller pump is changed by triangle piston formula motor, and its rotor except that pivoting, also will be made translational motion relatively in operation process.Rotor can be made periodically play with respect to axle like this, makes to produce friction in the rotor and the pump housing between the profile, reduces working efficiency, also can make axle produce fatigue ruption.Though the rotor pump running of single chamber is steady than Bicorn rotator pump and double-arc impeller pump,,,, thereby can influence the reliability of this pump so the vibration during rotor rotation is difficult to basic elimination so the centrifugal force of rotor can't balance because its rotor Half Speed rotates in pump shaft.
(3) summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, friction, big, the widely used two-chamber high concentration material of flow rotor pump, is used to solve prior art rotor pump rotor centrifugal force and is difficult to balance, can't eliminates the problems such as vibration that cause thus.
The technical solution of the utility model is: two-chamber high concentration material rotor pump is mainly by belt pulley, left side equilibrium block, right equilibrium block, pump shaft, end cap, eccentric cam, pump case, rotor, external gear, internal gear, bearing, composition such as guard shield and key, in the middle of pump shaft, this rotor pump is divided into two identical cavitys that work alone by dividing plate, two eccentric cams differ 180 ° with key at the pump shaft upper angle connection are installed, in, external gear number of teeth ratio is 2: 1, external gear is fastened on the dividing plate, and be placed on the pump shaft, internal gear and rotor set are integrated, and be contained on the eccentric cam by bearing housing, there is the gap in the interior profile of the external frame of rotor and pump case, and the gap is 1.5mm ± 0.5mm.
The inner outline equation of pump case is:
x＝Lcos(α/2)-rsinα
y＝-Lsin(α/2)-rcosα
The outer contour polar coordinates of rotor are expressed as:
R＝(L-x)-2rsinβ
In above-mentioned formula, r is the Pitch radius of external gear, and L is the distance of the summit of rotor to its center, and α, β are certain some angle of swing on the profile line, and x is for guaranteeing rotor and the gapped correction factor of pump case.
The utility model can reach following beneficial effect: owing to adopt the two-chamber design, two eccentric cam angles differ 180 ° with key joint on pump shaft, therefore centrifugal force equal and opposite in direction, the direction of two eccentric cams are opposite, thereby cancel each other out; Same because inside and outside gear ratio is 2: 1 and two rotors that Half Speed is rotated, and then same centrifugal force equal and opposite in direction, direction are opposite, cancel each other out, and have eliminated the vibration that centrifugal force causes.The unbalance moment that high-revolving two eccentric cam centrifugal force produce has been eliminated in the increase of left and right equilibrium block, improves bearing working life; The outer contour of rotor is through the correction factor correction, has the gap with the interior profile of pump case, eliminated contact friction, and then improved the reliability of two-chamber high concentration material rotor pump.

Fig. 2 is the right chamber sectional view of the utility model two-chamber high concentration material rotor pump.
(5) embodiment
Two-chamber high concentration material rotor pump shown in Figure 1 mainly is made up of belt pulley 1, right equilibrium block 2, pump shaft 3, end cap 4, eccentric cam 5, pump case 6, rotor 7, external gear 8, internal gear 9, dividing plate 10, bearing 11, left equilibrium block 12, guard shield 13 and key 14.Being distributed in two eccentric cams, 5 angles in two pump case 6 differs 180 ° and is bound up on the pump shaft 3 with key 14; External gear 8 is fastened on the dividing plate 10, and is placed on the pump shaft 3; Internal gear 9 is combined into one with rotor 7; Right equilibrium block 2 is fixed on the belt pulley 1; Left side equilibrium block 12 usefulness keys 14 are fixed on the left end of pump shaft 3, and cover with guard shield 13; Gapped between pump case 6 and the rotor 7 is non-contact.Driving pump shaft 3 by belt pulley 1 rotates, pump shaft 3 drives two eccentric cams 5 thereupon and rotates, thereby drive the center of circle skew that is sleeved on the rotor 7 on the eccentric cam 5 by bearing 11, this skew then drives rotor 7 by the variation of the internal gear on it 9 with external gear 8 (gear ratio 2: 1) contact points, and then rotor 7 is rotated in pump case 6, cause rotor 7 and pump case 6, end cap 4 and dividing plate 10 to surround the variation of volume, produce suction effect high concentration material.
The utility model not only can be widely used in the suction effect of high concentration sludge, also can be used for the suction effect of other high concentration material.
