| 检查油冷却器工作是否正常。对水冷式机型，可检查其进出口水管的温差，正常情况下应为5一8℃，低于5℃可能有结垢或堵塞现象，将会影响冷却器的换热效率，并造成散热不良，此时可将换热器拆下后进行清洗。 Check whether the oil cooler works normally. For water-cooled models, the temperature difference between the inlet and outlet water pipes can be checked. Under normal circumstances, it should be 5-8 ℃. If it is lower than 5 ℃, there may be scaling or blockage, which will affect the heat exchange efficiency of the cooler and cause poor heat dissipation. At this time, the heat exchanger can be removed and cleaned. 九、检查冷却水人口温度是否过高，水压及流量是否正常，对于风冷式机型则检查环境温度是否过高。冷却水的入口温度一般不应超过35℃，水压在0.3一0.5MPA之间流量应不小于规定流量的90％。环境温度不应高于40℃。如果达不到上述要求，可通过安装冷却塔、改良室内通风、加大机房空间等办法解决。还可检查冷却风扇工作是否正常。如有故障应进行检修或更换。 9、 Check whether the temperature of cooling water is too high and whether the water pressure and flow are normal. For air-cooled models, check whether the ambient temperature is too high. Generally, the inlet temperature of cooling water shall not exceed 35 ℃, the water pressure shall be between 0.3 and 0.5MPa, and the flow shall not be less than 90% of the specified flow. The ambient temperature shall not be higher than 40 ℃. If the above requirements cannot be met, it can be solved by installing cooling tower, improving indoor ventilation, increasing room space and so on. You can also check whether the cooling fan works normally. In case of any fault, repair or replace it. |
