ATOS Gear Pump Installation Instructions

The ATOS gear pump is a type of positive displacement pump. It consists of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases, creating a vacuum that draws in liquid. Conversely, the volume of the space on the meshing side decreases, forcing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The discharge pressure of the gear pump depends entirely on the resistance at the pump outlet.

When installing an ATOS gear pump, the following precautions should be taken:

1. Conduct a detailed inspection of all components; all parts must meet the relevant standards.

2. The perpendicularity of both end faces of the gears to the shaft centerline and the parallelism of both end faces of the gears must be qualified; the gear meshing should be good.

3. The shaft diameter should meet the technical requirements, and the coaxiality of the bushing or bearing with the shaft diameter must be qualified.

4. The gear end face clearance should be adjusted appropriately.

5. When tightening the end face bolts, apply force symmetrically and evenly; tighten while rotating the rotor. If jamming occurs, loosen the bolts and retighten.

6. When adding packing and tightening the gland, tighten while rotating the rotor; do not overtighten.

ATOS gear pumps are a type of positive displacement pump. They consist of two gears, a pump body, and front and rear covers forming two enclosed spaces. When the gears rotate, the volume of the space on the disengaged side increases, creating a vacuum that draws in liquid. Conversely, the volume of the space on the meshing side decreases, forcing the liquid into the pipeline. The suction and discharge chambers are separated by the meshing line of the two gears. The pressure at the discharge port of a gear pump depends entirely on the resistance at the pump outlet. A gear pump is a rotary pump that transports or pressurizes liquids by relying on the change and movement of the working volume formed between the pump cylinder and meshing gears. The structure of an external meshing double gear pump consists of a pair of meshing gears and a pump cylinder separating the suction chamber and the discharge chamber. As the gears rotate, the volume between the teeth at the point where the gear teeth disengage gradually increases, the pressure decreases, and liquid enters the space between the teeth under the pressure difference. With the rotation of the gears, the liquid between each tooth is carried to the discharge chamber. At this point, the volume between the meshing teeth at the point of engagement gradually decreases, discharging the liquid. Gear pumps are suitable for transporting lubricating liquids that do not contain solid particles, are non-corrosive, and have a wide viscosity range. The pump's flow rate can reach 300 m³/h, and the pressure can reach 3 × 10⁷ Pa. It is commonly used as a hydraulic pump and for transporting various oils. Gear pumps have a simple and compact structure, are easy to manufacture and maintain, and have self-priming capability, but they experience large flow and pressure pulsations and are noisy. Gear pumps must be equipped with safety valves to prevent damage to the pump or prime mover caused by the outlet pressure exceeding the allowable value due to some reason, such as blockage of the discharge pipe.
