Pump Packing Sleeve Segmented Threaded Design

The packing sleeve is divided into multiple functional segments: a tapered segment for insertion, a pilot and sealing segment for alignment and sealing, and an attachment segment for threaded fastening. This segmentation allows each segment to perform its specific function independently, eliminating the need for complex high-pressure press-fitting equipment while ensuring reliable installation.

Instead of using high-pressure force to push the packing sleeve into the bore, the invention uses a reverse approach: the tapered segment is inserted first, then the attachment segment is threaded onto the fluid input bore, and finally the packing sleeve is pulled into position using the threaded connection as an anchor point. This inverts the traditional press-fitting method, replacing high-pressure pushing with low-force threading and pulling.

The installation process inverts the traditional high-pressure approach by using low-pressure threading and pulling. The threaded attachment segment is screwed onto the fluid input bore at low pressure, then the packing sleeve is pulled into position using the threaded connection as an anchor, completely avoiding high-pressure operations and their associated safety hazards.

The invention replaces the high-pressure hydraulic mechanical system with a simple threaded mechanical connection. Instead of using hydraulic pressure up to 10,000 psi, the threaded attachment segment provides a secure mechanical anchor that allows the packing sleeve to be installed using minimal force, eliminating the need for high-pressure hydraulic equipment and improving safety.

The packing sleeve is segmented into functional sections with the attachment segment featuring external threads that directly engage with the fluid input bore. This segmentation eliminates the need for complex press-fitting equipment and multiple installation steps, allowing the packing sleeve to be installed quickly by simply threading it into place and pulling it into position.

The installation process is inverted to start with the tapered segment insertion, followed by threading the attachment segment onto the bore, and finally pulling the packing sleeve into position. This reverse sequence eliminates time-consuming high-pressure operations and allows for rapid installation by a single operator using simple tools.

The segmented design of the packing sleeve with its threaded attachment segment allows for simple manual operation. The external threads on the attachment segment enable a single operator to screw the packing sleeve onto the fluid input bore and pull it into position without needing multiple personnel to operate complex high-pressure equipment.

The inverted installation process starts with inserting the tapered segment, then threading the attachment segment onto the bore by hand or with simple tools, and finally pulling the packing sleeve into position. This sequence eliminates the need for multiple personnel to coordinate high-pressure system operations, making the installation easy to perform by a single operator.
