For self-suction-type piston pump, the hydraulic oil tank shall not be less than the lower limit of the oil standard, to maintain a sufficient number of hydraulic oil. The higher the cleanliness of hydraulic oil, the longer pump life. The most important part is the piston bearing paver hydraulic repair, if the bearing clearance occurs, it can not guarantee normal pump inside three pairs of friction pair gap, but also undermine the friction pair hydrostatic bearing oil film thickness of paving hydraulic repair phone, reduce piston bearing life. According to information provided by the pump manufacturer paver hydraulic repair company, the average life of the bearing is 10000h, more than this value will need to be replaced with new ports. Use the temperature below 70 degrees, if possible, preferably below 60 degrees hydraulic repair paver manufacturers, especially in the case of the high pressure of the overflow valve back into the six working oil temperature is high, or local heating by a heater etc. must pay great attention to. because under high temperatures will accelerate the oxidation. To control pollution, because it has a working oil pollutants will become a catalyst to accelerate the oxidation of the hydraulic oil in the summer with ISO-VG-46 winter with ISO-VG-32.
