When the object determines the work load, Cai systems working pressure (for pump maintenance force) determines the economic rationality of selected roller hydraulic pump repair system, the size of the work if the pressure is low, then the execution of the elements on people required to complete a given flow rate also people; if the working pressure is too high roller hydraulic repair price is on the high performance requirements of sealing pressure on the high grade components, the corresponding device into the wood is high. Working pressure is generally stand for 20 ~ 32MPa. Work has already begun degraded oil roller hydraulic repair Which is good, add new oil does not prolong life. Should be all the new ones. To control the hydraulic machinery and piping of oil spills roller hydraulic repair company, so that the flow to a minimum, so the chance of reducing the pump maintenance. Different manufacturers of working oil can not mix, as well as with vendors manufacture, but different name and rank of the need to avoid working oil mix. Due to the oil additive can cause deterioration. Hydraulic Compactor Repair | Weinan roller hydraulic repair | Xi'an Xi'an Chengtong Chengtong hydraulic repair hydraulic repair Limited.
