Excavators cylinder-color processing method: Many users have encountered excavator cylinder discoloration, I thought it was a problem with the quality of the fuel tank. In fact, in many cases how much of a mini-excavators, the situation has nothing to do with its color quality of the fuel tank, followed by small series will explain the reasons for their treatment tanks discoloration everyone. Cylinder turns black, blue or purple phenomenon, not the cylinder itself discoloration, but the cylinder surface covered with a layer of colored film, it is not the fuel tank itself. Under normal circumstances, the cylinder will first turn blue, the color deepened after, turn purple, and even eventually become black. The method of processing tanks discoloration problem: If it is a very minor part of the cylinder appears blue, you can not ignore it, over time, would disappear; if color more serious, the need to replace the oil seal and wear sleeve, and should try to avoid hydraulic oil high-temperature, over a period of time will return to normal. Most 泰安嘉 and Heavy Machinery Co., Ltd. hydraulic oil temperature control system of the hydraulic system power loss into heat, causing the temperature rise. As a result, not only the efficiency of the hydraulic system drops mini excavator manufacturers, but also accelerate oil deterioration. According to information on the hydraulic oil temperature is over 55 degrees every increase of 9 degrees, the oil service life will be shortened by half. Therefore, we should try to avoid the hydraulic oil temperature is too high. After the oil temperature control devices and energy saving control device combination in an alarm state, the device operates when the first hot-melt-temperature protection is set within a reasonable temperature range of the system, then closed magnet-type temperature limit switch, self-locking The temperature control switch open control functions. When the oil temperature rises to over-temperature protection workers set temperature of the hot melt, magnet-type temperature limit switch automatically disconnected, and temperature control switch pull. At the same time, the temperature control indicator lights mini excavators Which is good, give early warning indication. The indication signal and selected by the operation mode of the electronic energy-saving control module switches and electronic throttle control, throttle opening degree of the diesel engine is controlled using a diesel engine speed is reduced, thereby reducing the flow of the hydraulic pump, the hydraulic system to control the heat generated, avoiding oil liquid temperature continued to rise. After the temperature warning released by a pull-magnet-type temperature limit switch, eliminating the oil temperature effects on electronic energy-saving control module, allowing the excavator to restore normal operation.泰安嘉 and Heavy Machinery Co., Ltd.
