Shenhua Juneng successfully transformed wk

Shenhua Juneng successfully transformed wk-3 to repair major load-bearing bones such as leg bones 5 excavator dry oil supply device

China Construction machinery information

Guide: Recently, Shenhua Juneng equipment maintenance center successfully transformed w to become an open-loop K-35 excavator dry oil supply device. Wk-35 electric shovel realizes the lubrication of 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. Lower lubrication is divided into walking 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 realizes the lubrication of 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 intervals of 180s and 1200s respectively. Wk-35 must open the oil cap to store oil in the open air. With the extension of time, dust and impurities will melt into the dry oil tank, which is easy to cause the blockage of the reversing valve. The overloaded movement of Lincoln pump and the blockage of the dry oil reversing 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 characteristics of the movement of each mechanism of wk-35 excavator, the original reversing valve oil supply device was abolished, two 60 cm inlets were welded on the upper part of the dry oil mailbox, a Lincoln pump was added, and the standby solenoid valve in the electrical cabinet was used to realize the lubrication of the upper and lower parts, In 2018, global peek will usher in a peak demand. From the original one point control of multiple points to the current one point control of all points, the management mode of "run while sliding" will be adopted

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