Chemical equipment is a part of chemical machinery. Chemical machinery includes two parts. The first is chemical machinery, which mainly refers to equipment such as fans, compressors, and various pumps for fluid transmission. Its main components are moving machinery, commonly referred to as chemical machinery. The second is that chemical equipment mainly refers to static machinery, such as separation equipment such as tower, container, reactor equipment, etc., sometimes also known as non-standard equipment. The division between chemical machinery and other machinery is not very strict. For example, some pumps used in chemical process are also general equipment used by other industrial departments. Similarly, there is no strict distinction between chemical machinery and chemical equipment in the chemical process. For example, some reactors are often equipped with moving machines.
