Gear pump gear

Gear oil pump gear installed by the demolition of complex, the first move the claw coupling and the claw coupling teeth fixed teeth in the all-toothed position, and then the two fixing bolts in the positioning plate but not unscrew Insert the dowel pin on the engagement lever assembly into the hole on the rear side of the positioning plate (on the side of the Gear Pump). If the long slot on the positioning plate has reached the limit, the positioning pin still can not be inserted into the hole, you need to re-engage the lever assembly, change the position of its spline, after adjustment, tighten the two positioning plate fixing bolts and Engage the lever assembly fixing bolt. Finally, the lever assembly should be repeatedly pulled several times the lever assembly, the movable claw coupling should be free to slide from the hole to observe the view, the joint position of the two coupling teeth should be the whole tooth meshing, the separation position should be full tooth off. Gear pump noise, or vibration is very strong, it is estimated that the following aspects in addition to the problem: 1. Suction pipe or filter plugging 2. Gear pump suction pipe into the liquid surface shallow 3. Pipe into the air 4. Gear Pump discharge pipe resistance is too large 5 gear bearing or side plate serious wear 6. Gear pump rotation part of the interference 7. The viscosity of the inhaled liquid is too large 8. Gear pump suction height exceeds the rated weight can be handled by the gear pump vibration noise Problems: 1. Gear pump to eliminate the dirt on the filter 2. The suction pipe should be deep into the liquid pool around 3. Gear pump to check the joints to seal 4. Exhaust pipes and valves are checked 5. Gear pump removed Cleaning and repair defects or replacement 6. Remove the inspection and troubleshooting 7. Gear pump viscosity measurement and treatment according to Article VI of the first phenomenon in Article VI 8. Increase the level of inhalation
