Causes Of Overheating Of Hydraulic Cylinders
Heat sources in construction machinery: Construction machinery, like other machinery, generates heat during operation. There are three main heat sources in construction machinery. First, the combustion system of the diesel engine generates heat. Second, the flow of hydraulic oil in the hydraulic system generates pressure energy, which is dissipated into hydraulic oil and engine oil as heat. Third, frictional heat is generated during the operation of the hydraulic transmission and other moving parts in the transmission system.
Insufficient cooling of heat dissipation sources: Insufficient cooling of heat dissipation sources refers to a situation where the cooling device fails to effectively absorb and dissipate the waste heat generated by the heat sources in the machinery, particularly in the hydraulic cylinders. Several factors can contribute to this issue. Poor quality of the cooling hydraulic pressure can reduce the heat dissipation capacity. High ambient temperatures can also exacerbate the problem by increasing the overall heat generation. Furthermore, operating errors or improper maintenance can lead to excessive waste heat generation, further compromising the cooling efficiency.
This includes checking the quality and flow rate of the cooling hydraulic pressure, monitoring and controlling ambient temperatures, and implementing appropriate maintenance practices to avoid operational errors or malfunctions. Regular inspection and cleaning of cooling components, such as radiators or heat exchangers, can help maintain their efficiency and prevent overheating.
