Welcome to inquire! Contact: money work. 1.1.3 Other analysis of hydraulic system failure Tongchuan hydraulic maintenance units, often can not identify the location and root cause of failure immediately, in order to avoid blindness, it must be logical analysis or the use of causal analysis and other methods based on the principle of the hydraulic system of elimination Finally, the failure to identify the site of Tongchuan hydraulic repair, which is logical analysis method to find the fault. Between the gear end and end caps; between gears turning and the housing bore and the meshing of the two gears. Where the greatest impact on the leakage is an axial gap between the gear end and the end cap, through leakage axial clearance of the total amount of leakage can be 75 to 80 percent, because here a short way Tongchuan hydraulic leak repair quote, a large area of ??the leak. Axial gap is too large, the leakage volume, will reduce the volumetric efficiency; but the gap is too small Tongchuan hydraulic repair company, to increase the mechanical friction losses between the gear end and the end cap, will reduce the mechanical efficiency of the pump. Therefore, the design must be strictly controlled and the axial clearance of the pump manufacturing. ② trapped oil gear pump to be smooth, overlapping coefficient gear must be greater than 1,
