Hydraulic component selection is unreasonable. Boom cylinder non-standard specifications for 70/40 series, seals also non-standard paver hydraulic repair Which is good, high manufacturing cost and inconvenience of replacing the seals. Boom cylinder bore small paver hydraulic repair phone, is bound to make the system set pressure is high. Hydraulic system design is unreasonable. Control valves and hydraulic steering pump for a single series, the safety valve set pressure points 16MPa, while the rated working pressure of the hydraulic pump is 16MPa. Pump often work at full load or prolonged overload (high pressure) situation, and the system has a hydraulic shocks, oil changes for long periods, hydraulic oil contaminated hydraulic paver repair prices, increased pump wear and tear, so that hydraulic pump shell burst (after such failure has been found). Absolute pressure of the liquid in the tank must be equal to or greater than the atmospheric pressure, which is a positive displacement fluid pump can suck external conditions. 1.1 Reach and maintain a satisfactory level of cleanliness initial chemical cleaning and processing systems internal surface (components, pipe and hose). Hot oil flushing system to reach the target cleanliness. Inspection and assessment of cleanliness has reached the requirements. Dismantling wash circuit according to the following steps to avoid contaminants from entering the system has been cleaned. Seal all joints and flange components.
