Vertical Inline Pump (API610/OH3)

1. Pressure-bearing shell: The design pressure of the pump body and pump cover is 5.0Mpa, forming an independent pressure chamber, which is safe and reliable. The pump body has a volute structure. If the outlet is larger than or equal to 80mm, the double volute structure can well balance the radial force and ensure the rigidity of the rotor. The pump cover is rigidly designed, with strong pressure bearing capacity and high reliability;

2. Rotor: It adopts a closed impeller, and uses a balancing hole and sealing ring structure to balance the axial force: the shaft is a bare shaft structure, and the stiffness index of the pump shaft meets the requirements of API61011 "Appendix K." At the same time, the impeller nut anti-reverse structure is used to meet The on-site working condition requirements improve the safety and stability of the equipment;

3. Bearing components: The bearing components adopt an overall pull-out design, which enables inspection and maintenance of the pump without moving the inlet and outlet pipelines and motors; the bearings use 40-degree angular contact ball bearings and cylindrical roller bearings installed back-to-back to withstand the load. Radial force, rotor weight and residual axial force; the bearings are lubricated with grease, which is easy to keep in the bearings and can also prevent the impact of dust and moisture on the bearings. The structure is economical and reliable; equipped with a mechanical oil seal structure, it can effectively prevent lubricating oil Leakage and prevent dust and sewage from entering the bearing box to ensure clean operating conditions for the bearing;

4. Friction pair: The pump body, pump cover, and impeller are all equipped with wear-resistant sealing rings. The clearance and hardness requirements of the sealing rings meet the requirements of API610 standards. Long service life and easy replacement of spare parts;

5. Mechanical seal: The sealing cavity complies with the requirements of API6824th "Shaft Seal System for Centrifugal Pumps and Rotary Pumps" and can be configured with various forms of seal flushing and cooling solutions. It is suitable for various complex working conditions and has a wide range of uses;

6. Motor frame: The motor frame adopts a rigid structure and is connected to the pump body or directly to the foundation, so that the weight and vibration of the motor are not directly transmitted to the bearing frame, which can well ensure the operational stability of the pump.
