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