在涂装生产中,喷漆后的工件一般需要涂装烘干设备进行烘干,喷粉的工件都需要涂装烘干设备进行固化，烘干设备能耗大,烘干设备设计的好坏,与能源的有效利用及运行成本的高低有着直接的关系。
加强涂装烘干设备润滑工作，对于延长关键件使用寿命、降低维修费和减少设备故障都有着重要的意义。目前已有的高温润滑方法有气体润滑、固体润滑和油脂润滑。
1.气体润滑
气体润滑是由具有足够压力(动压或静压的方式)的气膜(气体润滑剂)将运动副摩擦表面隔开，气膜来承受外力作用，从而降低运动时的摩擦阻力与零件表面的磨损。气体润滑剂摩擦因数低、温度变化对润滑剂的粘度影响小，因而适用于高温润滑。但气体润滑剂的承载力低，要有外部供给稳定压力的气源，对摩擦副支承元件的制造精度要求高，多用于滑动摩擦面的润滑，不适用于涂装烘干设备润滑。
2.固体润滑
固体润滑是使用粉末状或薄膜状的固体润滑剂对作相对运动的摩擦副表面进行润滑，以减少摩擦与磨损。固体润滑剂使用温度范围宽，只要不超过其熔点，固体润滑剂就能保持基本形态不变。而且固体润滑剂具有很高的承载能力，在传动系统低速运转情况下的防止粘滑性能好，具备满足特殊工况下润滑的全部条件。但固体润滑剂的摩擦因数比润滑油脂的摩擦因数大，故单独使用固体润滑剂时，设备所消耗的能量大。虽然可以将固体润滑剂粉末添加到润滑油、润滑脂中，以提高润滑油和润滑脂的承载能力、改善边界润滑状态，但有些固体润滑剂粉末在高温下不仅对金属具有一定的腐蚀作用，还会降低润滑油和润滑脂的抗氧化能力。用量过大时，甚至会引起轴承的“咬粘”。因此，在涂装烘干室设备的润滑中，不建议采用含固体添加剂的润滑油和润滑脂、输送机被动轮的轴套等。
3.油脂润滑
采用润滑油或润滑脂是基础，也是润滑效果很好的润滑方法，但其基础油(无论是矿物油还是合成油)的极高耐用温度都不会超过350℃。对于普通的汽车涂装而言，这个温度完全可以满足要求。
总之，对于涂装烘干设备润滑，在可选择的情况下，油润滑是主要的，其次是脂润滑，只有在油、脂都无法满足的特殊工况下，才考虑固体润滑，这是选择润滑方法的原则。
