summary
Rubber gear pump, also known as spiral piston pump or cam rotor pump, belongs to self suction, valve free, positive displacement pump. Driven by an electric motor, during operation, two synchronous rotors are parallel and facing each other, rotating clockwise and counterclockwise respectively, forming a drainage chamber. The open chamber at the pump inlet is filled with transported materials, which are shifted to the discharge end in the direction of volumetric flow, completing the process of medium transportation. The displacement is related to the speed, because the structure is symmetrical, as long as the driving direction is changed, the delivery direction of the pump can be changed. When stopped, the rotor is arranged and almost in a sealed state. The material types of rotors and the installation forms of pumps are diverse, which can meet the requirements of various working conditions.
characteristic
1. The suction head of the rubber gear pump can reach 9 meters, and the outlet pressure can reach 1.6 MPa.
2. Not only can it transport mixed media of steam, liquid, and solid. It is also suitable for conveying various materials with a viscosity of 1-100000 cst, so it is also known as a colloid pump.
3. The structural design is reasonable, allowing it to run dry for 20 minutes without causing damage to the pump. Moreover, it improves the non clogging capacity of the medium, especially suitable for sewage sludge treatment.
4. Excellent symmetrical arrangement, the pump inlet and outlet can be freely exchanged, and the medium delivery direction can be changed by changing the rotor direction, especially used in loading and unloading situations.
5. Reasonable structure, intermediate isolation chamber, filled with lubricating oil to avoid oil contamination caused by pumping medium. The shaft sleeve can prevent corrosion, and the medium being transported will not come into contact with the shaft.
6. Adopting a containerized mechanical seal structure, immersed in lubricating oil, not only prolongs its service life, but also ensures that the mechanical seal does not leak.
