Suction chamber pressure and the pressure oil chamber is inconsistent, both rely on the end face of the gear cover; the gap between the crests and the reciprocal movement of the pump seal. So these two gap size is very important, a big gap roller hydraulic repair Which is good, liquid back severely, reducing the efficiency of hydraulic compactor repair factory, and even unable to work; the gap is small, the high friction, the motor burned even stuck gear bad. This indicates that the hydraulic roller maintenance organizations, these two gaps need to ensure the precision and accuracy of installation. When the object determines the work load, Cai systems working pressure (for pump maintenance force) determines the economic rationality of the selected hydraulic system, the size of elements if the working pressure is low, people are executed on roller hydraulic repair, complete the required flow rate for a given person too; if the working pressure is too high, the sealing performance requirements will be high, the pressure on the high grade components, the corresponding device into the wood is high. Working pressure is generally stand for 20 ~ 32MPa. Roller hydraulic repair factory, Tongchuan roller hydraulic repair, hydraulic repair Chengtong Xi'an Xi'an Chengtong hydraulic repair Limited.
