With the development of society, hydraulic cylinder gear pumps have been widely used, and there will be a phenomenon of poor rotation during use. What is the reason for this phenomenon? Let me introduce you to the following: 1. The axial clearance or radial clearance of the hydraulic cylinder is too small. Re-adjust and adjust. 2. The hydraulic cylinder gear pump has dirt and disintegration to remove foreign matter. 3. Misassembly: The machining reference surface of the two pin holes of the hydraulic cylinder gear pump is not the assembly reference surface. If the pin is driven in first, then the screw is tightened and the pump will not turn. The correct way is to tighten the screw while turning the gear pump, then drill the pin hole and drive the pin. 4. The coaxiality of the pump and the engine coupling is poor, and the coaxiality should be within 0.1mm. 5. The parts inside the hydraulic cylinder gear pump are not demagnetized, and all parts must be demagnetized before assembly. 6. The quality of the needle roller sleeve is unqualified or the needle is broken, repaired or replaced. 7. The hydraulic oil cylinder working oil output port is blocked to remove foreign matter. The above seven points are all factors that can cause the hydraulic cylinder gear pump to rotate poorly. This requires us to maintain it in daily use, prevent unnecessary problems, reduce the frequency of occurrence, and reduce its maintenance cost. . 2 tons of Mini Excavator, the overall use of engineering additive track, wear-resistant and stable; 2 Ton Mini Excavators,2 Ton Mini Excavator Machine,Mini Excavator 2 Ton,2 Ton Small Excavator Shandong Davoo Machinery Co., Ltd.
