China Construction Machinery Information

Guide: Recently, the equipment maintenance center of Shenhua zhuneng company successfully transformed the dry oil supply device of wk-35 excavator. Wk-35 electric shovel realizes the upper and lower lubrication through the reversing pressure of the reversing valve. The upper and lower parts share a Lincoln pump, and the upper lubrication interval is 900s. Lower lubrication is divided into travel mechanism lubrication

recently, the equipment maintenance center of Shenhua zhuneng company successfully transformed the dry oil supply device of wk-35 excavator

wk-35 shovel is lubricated with strong toughness, conductivity and thermal conductivity at the upper and lower parts through the reversing pressure of the reversing valve. The upper and lower parts share a Lincoln pump, and the upper lubrication interval is 900s. The lower lubrication is divided into traveling mechanism lubrication and excavation mechanism lubrication, with an interval of 180s and 1200s respectively. Wk to avoid wasting power and the rotating part -35 in the pump must open the oil cover to store oil in the open air. With the extension of time, dust and impurities are integrated into the dry oil tank, which is easy to cause the blockage of the change-over valve. The overloaded movement of Lincoln pump and the blockage of the dry oil change-over valve have shortened the service life of Lincoln pump, reduced the equipment dispatch rate and greatly increased the production cost

therefore, in full consideration of the different movement characteristics of each mechanism of wk-35 excavator, the original reversing valve oil supply device was abolished, two 60cm inlets were welded and cut at the upper part of the dry oil mailbox, a Lincoln pump was added, and the backup solenoid valve in the electric cabinet after holding the sample was used to realize the upper and lower lubrication, In this way, the lubrication management mode from the original point of controlling multiple points other than the aforementioned manufacturers to the current point of controlling each point

after transformation, the replacement rate of Lincoln pump is greatly reduced and the dispatching rate of electric shovel is increased
