Suction vehicle lubricating oil effect Sewage vehicle lubricants have the following effects: 1. Lubrication: The oil film contacts between the surfaces of moving parts to reduce wear of parts and engine power loss. 2. Cleaning function: Use the circulating oil to flush the surface of the parts, remove the worn-out metal chips, and keep the surface of the lubricating parts clean. 3. Cooling: Through the circulation of the lubricating oil, take away the heat generated by the friction and maintain the proper working temperature of the parts. 4. Sealing effect: rely on oil film to improve the sealing effect of the parts. For example, the oil film formed between the piston and the cylinder wall can reduce the air leakage when the piston moves. 5. Anti-corrosion effect: The oil film can prevent the surface of the part from contacting with moisture and air to cause oxidation and rust. As an important form of Centrifugal Pump, double suction pump is widely used in engineering because of its high lift and large flow. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.
