In the process of daily maintenance and repair of water injection pumps, it is necessary to disassemble and replace the valve assembly of the water injection pump. The valve assembly is mainly composed of a valve pressure sleeve, a combination valve and a positioning sleeve, which are located in the hole groove on the inner edge of the water injection pump. Since the inner diameter of the hole groove is small and the interior is full of sewage, and due to the long-term injection of sewage, the valve assembly in the cavity of the water injection pump is corroded, rusted and stuck, making it difficult to remove it smoothly for maintenance. The operator is therefore faced with great work difficulties. At present, there is a lack of an efficient and multifunctional disassembly and assembly device on the market that can easily cope with the disassembly and replacement of the valve assembly of the water injection pump and improve maintenance efficiency.
