为了保证注塑机液压油的传动效果,必须保证油冷却器的冷却功能。因此,必须定期对油冷却器进行清洗。对于除去冷却器铜管内壁的水垢,用市售的水垢清洗剂即能如愿以偿,但对管外壁的油垢清洗却颇为费事。为此,笔者查阅了有关资料,配成油清洗剂,经多次验证,效果十分好。例如我们有一台注塑机,十多年未清洗过,高温季节有时油温达70℃左右,而用此法清洗,油温降至55℃以下,从而保证液压油的 In order to ensure the injection molding machine hydraulic oil transmission effect, we must ensure that the cooling function of the oil cooler. Therefore, the oil cooler must be cleaned regularly. To remove scale from the inner wall of the cooler copper tube, a commercially available scale cleaner can do what it takes, but cleaning the outer wall of the tube is quite troublesome. To this end, I access to the relevant information, with oil cleaning agent, after repeated verification, the effect is very good. For example, we have an injection molding machine that has not been cleaned for more than 10 years. Sometimes, the oil temperature reaches about 70 ℃ during the hot season. When this method is used, the temperature of the oil drops below 55 ℃ to ensure that the hydraulic oil
