一种组合式齿轮泵壳体
By designing a modular gear pump housing, the high maintenance costs and limited oil inlet methods of traditional gear pumps (which cannot meet the needs of different scenarios) are solved. This design enables flexible oil inlet and disassembly, facilitating rapid oil inlet and maintenance. It also addresses the maintenance costs and operational stability issues associated with traditional gear pump housings, allowing for flexible oil inlet and inspection, rapid oil inlet operation, and convenient oil inlet and maintenance. This reduces equipment maintenance costs and eliminates the need for complete disassembly and reassembly in traditional technologies.
