Cycloidal internal gear pump


Introduction to the Slant-type intramatotic pumps are widely used in different properties and different viscosity media delivery due to the different materials and their unique structures. The pump is mainly composed of internal, outer rotors, axes, pump bodies, front cover, bracket, seal, bearing, etc. The seal has two forms of mechanical sealing and filler sealing, which is selected for high temperature, high viscosity and strong corrosive media, and a filler seal is selected.
When delivering a crystalline material, it can be designed with an insulation jacket on the front cover and the pump body, and thermally thermally melt in operation.

Application range of internal gear pump:
1. Food & Beverage: Dairy, Latex, Chocolate, Syrup, Cheese, Malt, Beer
2. Fruit concentrate: pudding, jam, jelly, ketchup
3. Paste products: fat and grease, etc.
4. Cosmetics: Cream, detergent, hair gel, fragrance oil, etc.
5. Oil: crude oil, heavy oil and refined oil, etc.
6. Chemical industry: dye, fat, solvent, resin and polymer
● Product advantages:
(1) The conveying liquid is stable, there is no pulsation, small vibration, low noise.
(2) There is a strong self-suction performance.
(3) Correctly use the parts material to deliver a variety of corrosive media, using temperature up to 200 ° C.
(4) The inside and external rotor turns the same, small wear, long service life.
(5) The speed and flow of the pump are linearly linear, and the speed can be appropriately changed to change the flow of the pump.
(6) Specially applicable to the delivery of highly viscous media.
Transmission of the internal gear pump:
The transmission of the internal gear pump generally has the following forms
1. Motor + speed ratio reducer: This transmission is simple, and the speed of the rotor is constant, that is, the non-adjustability of the flow is determined.
2. Motor + Mechanical Friction Stepless Transmission: This transmission is realized by manual adjustment. Its characteristics are safe and reliable, the torque is large, and the flow is stable. The disadvantage is that non-automatic adjustment, more troublesome, speed up during the operation, and must not speed up in the downtime, which uses maintenance reference manufacturer's instruction manual.
3. Variable frequency motor + frequency converter: This method can achieve automatic adjustment of the speed, that is, the traffic of urinary stepless adjustment is realized. The advantage is that the degree of automation is high, and the low speed torque is large. A disadvantage is that the prices of the inverter are high. It uses maintenance reference manuals for the manufacturer.
