Asphalt pump on the principle of belonging to a gear pump, gear pump works is a pair of gears meshing with each other to generate power to drive the media to work. The use of a long time, often the following four problems: First, the internal parts of asphalt pump wear: asphalt pump internal parts wear will cause internal leakage, floating sleeve and gear leaked between the large area, resulting in the main part of the internal leakage . This part of the leakage accounted for about 50% of the total internal leakage, wear and tear of asphalt pump gear pump internal leakage volumetric efficiency decline, asphalt 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 surface, due to work floating sleeve will be a small amount of movement caused by wear and tear, resulting in slow or can not enhance the farm tools, such a floating sleeve must be replaced or repaired. Second, asphalt pump casing wear: asphalt pump wear mainly refers to the wear of the floating sleeve hole: gear shaft and sleeve of the normal gap is 0.09 ~ 0.175mm, the maximum shall not exceed 0.20mm. When the gear work by the role of pressure oil, gear tip close to the asphalt pump casing, worn pump low pressure chamber part. In addition, the casing is a week-like wear surface, this wear is mainly due to the net oil added, so you must add oil without impurities. Third, asphalt pump seal wear, plastic seal aging. Unloading the rubber seal aging deterioration, loss of elasticity, the high-pressure oil chamber and the low-pressure oil chamber lost seal isolation, will produce high-pressure oil chamber pressure to the low-pressure oil chamber, known as "leakage", which reduces the pump Work pressure and flow. CB46 gear pump its normal working pressure of 100 ~ 110kg / cm2, the normal oil volume is 46L / min, the standard unloading sheet rubber seal is 57 × 43. Since the tight seal is PG25 × 42 × 10 of the skeleton oil seal, its damage or long-term failure, the air from the seal and the journal of the gap between the shaft or from the inlet plate and the oil pump housing junction is sucked into the pump, The return pipe into the tank, a large number of bubbles in the tank. Will cause the tank of oil to reduce the engine oil tank in the phenomenon of increased oil, so that agricultural tools to enhance slow or can not be improved. You must replace the oil seal to eliminate this fault. Fourth, insufficient or no oil pump asphalt pump phenomenon: working equipment to enhance slow, when lifting trembling or can not be improved; tank or tubing bubble; lift hydraulic system sends "jack, jack" sound; tractor just started Work device can be improved, work for a period of time after the oil temperature rises, the slow increase or can not be promoted; light load can be improved, heavy load can not be improved.
