? Oil temperature is too high A. What are the reasons: oil hydraulic systems to maintain appropriate excavator schools, generally in the range of 35 ~ 60 ℃ appropriate, Taian excavator schools Which is good, cause the oil temperature is too high The main reasons are: (1) the system efficiency is too low, Tai'an excavators school phone, cell capacity is small, the flow rate is too high; bad (2) Fuel tank capacity, or heat; viscosity (3) oil is too large; (4) Oil qualitative change bad, viscosity school address Tai'an excavator, oil increases, increase the resistance; good (5) cooling performance. Troubleshooting steering hydraulic steering gear failure is a very common form of failure, which includes a variety of fault types: 1, suddenly felt heavy steering or steering wheel turn no: possible causes are (1) Oil is not sufficient. Insufficient amount of oil tank, the oil viscosity is too large, oil filter blockage can lead to the pump suction without oil. Should the tank liquid level verification, add enough hydraulic oil; suitable replacement fluid; clean or replace the filter. Tai'an excavators school, Kerry and excavators school (online consultation), excavators school by 泰安嘉 and Heavy Machinery Co., Ltd. Taian Jia and Heavy Machinery Co., Ltd. (www.tajhzg.com/) is Tai'an, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Heavy leader in Kerry and the staff warmly welcome all inquiries negotiations to create Kerry and heavy industry a better future.
