The internal rotor cycloid gear pump outer rotor tooth is arc, the inner rotor tooth profile is short equatorial equatorial line, also known as the rotor pump. Xiaobian now to say that the internal gear cycloidal gear features and working principle. Internal gear cycloid pump First, the internal gear cycloid gear pump Features Internal gear cycloidal gear pump is equipped with oil pan (front and rear cover), the outer rotor (driven wheel) and eccentric placed in the pump rotor (active Round) and other components. The inner and outer rotors differ by one tooth, the inner rotor is six teeth in the figure, and the outer rotor is seven teeth. Because the inner and outer rotors are multi-tooth meshing, a number of sealed volumes are formed. Internal gear meshing cycloidal gear has many advantages, such as compact structure, small size, fewer parts, speed up to 10000r / mim, smooth movement, low noise, high volumetric efficiency. Drawback is the large flow pulsation, the rotor manufacturing process is complex, so far, has been used powder metallurgy pressing. With the development of industrial technology, the application of cycloidal gear pump will be more and more widely available Internal gear cycloidal gear can be positive and negative, can be used for hydraulic motors. Second, the internal gear cycloidal gear pump works When the inner rotor around the center O1 rotation, the outer rotor driven around the outer rotor O2 for the same direction of rotation. At this time, the seal volume C (in the figure, female part) formed by the inner rotor tooth tip A1 and the outer rotor tooth valley A2 gradually expands with the rotation of the rotor and thus forms a partial vacuum, Window b is sucked into the sealed chamber, to A1 ', A2' position, the maximum closed volume, then the oil absorption is completed. When the rotor continues to rotate, the oil filled sealing volume gradually decreases, the oil is squeezed, and the oil is discharged through the other oil distribution window a until all the other teeth of the inner rotor and the outer teeth A2 All engaged, the oil pressure is completed, the inner rotor per revolution, the inner rotor tooth top and outer rotor tooth valley formed by the seal of each volume to complete suction and pressure of oil each time, when the continuous rotation of the rotor is completed Pump suction and discharge work.

Overhead Sectional Door
Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
