The axial balance at low pressure is achieved by using double bushes; the power rotor and idler rotor are tensioned when running to prevent deformation of screws; meanwhile, the friction of idler rotors are reduced for better rotation conditions;
High grade of product, with exquisite appearance and delicate components:
① The most components are made of aluminum alloy by accurate die casting;
②The product is of anti-corrosion, free of paint, esthetic;
③ Innovative design in structure, simplifying the complete design under the conditions of performance requirements are met, resulting into a simple and compact product;
④ Small size and light weight: its size is 1/2 of that of conventional products, weight is 1/3 of that of conventional products;
Because of the symmetrical engagement of two driven screw and active screw, the radial force acting on the active screw is completely balanced, and the active screw does not bear bending load. The radial force acting on the driven screw is supported by the pump cylinder liner along its whole length, without additional bearings at the outer end and basically without bending load. In operation, a layer of oil film formed between the outer surface of screw and the inner wall of pump cylinder can prevent the direct contact between metals and greatly reduce the wear of screw tooth surface.
Like other volumetric pumps, when the outlet of the pump is completely closed, the pressure in the pump will rise to the danger of damaging the pump or overloading the motor. Therefore, safety valves must be installed at the suction and discharge ports of pumps. Shaft seals are usually mechanical seals and can take different forms according to the working pressure.
