For company product repair services, according to the product repair and disassembly intensity, it is divided into on-site repair and factory repair;
1. On-site maintenance: For some products that are easy to maintain and disassemble, such as float valve cores and arrow shapes, parts such as seals and springs can be replaced through some simple tooling. This greatly saves repair costs and time, etc.
2. Factory maintenance: This mainly refers to some complex products, such as impactors and multi-stage circulation heads. Taking the impactor as an example, due to multiple impacts on site, the product usage cannot be visually inspected from the appearance, and can only be returned to the factory or repair station for disassembly and maintenance using a disassembly rack
