After readjusting the mechanical neutral position of the plunger pump, it is also necessary to reset the control neutral position. The control neutral position establishes the reference point for the pump control system and ensures correct operation of the pump. When the mechanical neutral position is changed, it affects the position of control components such as control pistons, valves or control linkages. Therefore, the control system needs to be recalibrated to match the new mechanical neutral position. The exact procedure for resetting the control neutral position may vary depending on the specific pump and control system design. It usually involves following the manufacturer's instructions or consulting the technical documentation that came with the pump. The following are some general steps that may be involved in resetting a displacement pump control neutral position: 1. Determine the control components: Determine the control components that need to be adjusted according to the design of the pump. This can include control pistons, control valves or control linkages. 2. Locate the control neutral adjustment: Identify the specific adjustment mechanism or set screw that controls the neutral position of the control components. These adjustments are usually located near the control components or on the control valve assembly.

Adjust Control Neutral Position: Use the appropriate tool to make incremental adjustments to the control neutral position. Follow the manufacturer's instructions to ensure proper alignment and positioning. 4. Test and Verification: After adjustments are made, test the operation of the pump to ensure it will function properly in both directions. Verify that the pump is achieving the desired flow and pressure levels. 5. Make minor adjustments if necessary: If the pump is not performing as expected, further adjustments may be required. Follow the manufacturer's guidelines or consult a hydraulics expert to fine-tune the control neutral position. 6. Safety Precautions: Before making any adjustments, make sure the system is depressurized and all appropriate safety measures are in place. This includes shutting off power, depressurizing the system, and following proper lockout/tagout procedures. 7. Documentation and Guidance: Refer to the manufacturer's documentation, technical manual, or guidance for the model of plunger pump being used. These resources typically provide step-by-step instructions for resetting the control-neutral position and may include specific parameters or recommended procedures. 8. Incremental adjustments: When adjusting the control neutral, it is recommended to make small incremental changes and test the operation of the pump after each adjustment. This method allows for fine tuning and ensures that the performance of the pump remains within the desired range.
