Surface sticking technology of circular arc gear pump

The surface coating technology of circular arc gear pump has been widely used in equipment maintenance in China. Gear oil pump is suitable for the repair of parts and equipment of various materials. The working principle of circular arc gear pump is that the adhesive added with special fillers such as molybdenum disulfide, metal powder, ceramic powder and fiber is directly coated on the surface of materials or parts to make it have the functions of wear resistance and corrosion resistance. It is mainly used for surface strengthening and repair. Its process is simple, convenient, flexible, safe and reliable. It does not need special equipment. It only needs to apply the prepared glue to the cleaned part surface and repair it after curing. It is often operated at room temperature. The circular arc gear pump will not produce thermal power equivalent influence and deformation of the parts.

Installation sequence of circular arc pump:

(1) Place the unit on the foundation with anchor bolts, and place pairs of pads between the base and the foundation for positive use.

(2) Loosen the coupling, place the level on the pump shaft and base respectively, adjust the wedge pad to make the unit level, and properly tighten the anchor bolts after alignment to prevent walking.

(3) Pour the base and anchor bolt holes with concrete.

(4) After the concrete is dry, check whether the base and anchor bolts are bad and loose. After inspection, tighten the anchor bolts. After passing the inspection, tighten the anchor bolts, and recheck the levelness of the pump.

(5) Correct the coaxiality of pump shaft and motor shaft. The deviation on the circle at the coupling is allowed to be less than 0.1mm. The gap between the two coupling planes shall be 2 ~ 3mm. On the end faces of the two couplings, the difference between the maximum and minimum gap shall not exceed 0. 3 mm.

(6) After connecting the pipeline and determining the rotation direction of the prime mover, connect the coupling and check the coaxiality of the circle again.

(7) The final inspection shall be conducted after the actual test run of the unit for 3 ~ 4 hours. If there are no defects, the installation is considered to be qualified.

(8) In order to prevent sundries from falling into the machine during installation, cover the unit holes.

(9) Before starting the circular arc gear pump, clean the inlet and outlet pipelines, and add a filter at the inlet section of the circular arc gear pump to prevent sundries from entering the pump.
