Arc gear pump housing wear mainly floating shaft sleeve wear (gear shaft and sleeve of the normal gap is 0.09 ~ 0.175mm, the maximum shall not exceed 0.20mm). Gear work by the role of pressure oil, the gear tip close to the pump housing, wear low pressure chamber part of the pump. Another kind of abrasion is circular wear in the working face of the circular arc gear pump housing. The wear is mainly caused by the net oil added, so the oil without impurities must be added.
Arc gear pump gear with double arc sinusoidal tooth shape manufacturing. Compared with the involute gear, it has the most prominent advantage that the tooth profile has no relative sliding during gear meshing. Therefore, the tooth surface has no wear, stable operation, no fluid due to low noise, long service life and high efficiency. The pump out of the shackles of the traditional design, making the gear pump in the design, production and use into a new field.
Arc gear pump internal parts wear Pump internal parts wear and tear can cause internal leakage. Among them, the leakage area between the floating bushing and the gear end face is large, which is the main part of the internal leakage. This part of leakage accounted for 50% of the total internal leakage of about 70%. The wear and tear of the internal leakage gear pump volumetric efficiency decline, arc gear pump output power is much lower than the input power. The loss of all the heat into the heat, it will cause the pump overheating. If the combination of flat compression, due to work floating sleeve will be a small amount of exercise caused by wear and tear, resulting in slow or can not enhance the farm tools, such a floating sleeve must be replaced or repaired.
