High Pressure Hand Pump Calibrator User Manual

1. Introduction

This manual provides essential information for the safe and effective operation, setup, and maintenance of the Ace Instruments High Pressure Hand Pump Calibrator, Model DPI-2300. This device is designed for precise pressure and vacuum generation, making it ideal for field calibration, laboratory use, and testing of various pressure instruments.

The DPI-2300 is a robust and reliable tool, featuring a dual source for pneumatic pressure and vacuum, a built-in fine adjust vernier, and a needle valve for controlled pressure release. Its ergonomic design ensures comfortable use during extended calibration tasks.

2. Safety Information

Always adhere to the following safety guidelines to prevent injury and damage to the calibrator or connected equipment:

• Do not exceed the maximum rated pressure of the calibrator (600 Kg/Cm2) or the device under calibration.
• Ensure all connections are secure and leak-free before applying pressure.
• Use only clean, compatible fluids (water/oil) as specified for pressure generation.
• Avoid connecting the pump to external pressure sources.
• Always release pressure slowly and in a controlled manner using the needle valve.
• Wear appropriate personal protective equipment (PPE) if required by your work environment.
• Keep the calibrator clean and free from debris.

3. Product Overview

The DPI-2300 High Pressure Hand Pump Calibrator is a compact and portable device designed for generating precise pneumatic pressure and vacuum. It consists of a main pump body, comfortable handles, a transparent reservoir, and various control valves.

Key components include:

• Caliper Handle: Used to generate pressure or vacuum.
• Fine Adjust Vernier: For precise pressure adjustments.
• Needle Valve: Controls pressure release.
• Selector Valve: Switches between vacuum and pressure generation modes.
• Reservoir: Transparent chamber for the operating fluid.
• Connection Ports: For attaching the device under calibration (UUC) and master gauge.

4. Setup

Before operating the calibrator, ensure proper setup:

1. Unpacking: Carefully remove the calibrator and all accessories from its packaging. Verify that all components listed in the supply scope are present: 1 Unit of Calibrator, 3 Nos Reducers (1/4", 1/2", 3/4").
2. Fluid Filling (if applicable): For hydraulic operation, ensure the reservoir is filled with the appropriate clean fluid (water or oil) as per your application requirements. Do not overfill.
3. Connecting Devices:
   • Attach the master gauge (reference standard) to one of the designated ports.
   • Connect the device under calibration (UUC) to the other designated port. Use the provided reducers (1/4", 1/2", 3/4") if necessary to match the thread sizes.
   • Ensure all connections are hand-tight or wrench-tightened as appropriate to prevent leaks, especially at high pressures.

5. Operation

The DPI-2300 allows for both pressure and vacuum generation. Follow these steps for operation:

1. Select Mode: Use the selector valve to choose between pressure generation or vacuum generation.
2. Generate Pressure/Vacuum: Squeeze the caliper handles repeatedly. This action moves a piston back and forth, drawing and delivering fluid to generate the desired pressure or vacuum.
3. Coarse Adjustment: Continue pumping until the pressure/vacuum is slightly below the target value.
4. Fine Adjustment: Use the built-in fine adjust vernier for precise adjustments to reach the exact target pressure or vacuum. Turn the vernier knob slowly to increase or decrease the pressure incrementally.
5. Pressure Release: To release pressure, slowly open the needle valve. This allows for controlled depressurization of the system.

6. Maintenance

Regular maintenance ensures the longevity and accuracy of your calibrator:

• Cleaning: After each use, wipe down the exterior of the calibrator with a clean, damp cloth. Ensure no fluid residue remains, especially around connection points.
• Fluid Management: If using fluid, periodically check the fluid level and quality. Replace fluid if it appears contaminated or discolored. Use only recommended fluids.
• Storage: Store the calibrator in a clean, dry environment, away from extreme temperatures and direct sunlight. Ensure all pressure is released from the system before storage.
• Inspection: Regularly inspect hoses, connections, and seals for any signs of wear, damage, or leaks. Replace worn components as necessary.
