2.Shape Structure
| NO. | DESCRIPTION | FUCTION |
| 1 | Standard table interface | For connecting a standard pressure gauge (thread size M20X1.5) |
| 2 | Pressure test interface | Connect the calibrated pressure instrument interface (thread size M20X1.5) |
| 3 | Liquid injection mouth cap | Filling the pressure measuring medium into the liquid storage cup and exhausting the function |
| 4 | Shut-off valve | Cut off the connection between the pressurizing pump and the detection part to keep the measurement part stable |
| 5 | Pressurized handle | Lifting and pressing down |
| 6 | Pressurization and fine-tuning | Supercharging/precise adjustment of applied pressure |
| 7 | Pressure relief valve | Unscrew to release the pressure in the pump |
| 8 | Drain pipe | The pressure relief valve is opened to discharge the pressure measuring medium, and the pipe head is inserted into the liquid injection port if it is not discharged. |
| 9 | Filter | Filter the dirt on the output end and enter the pressure making system (clean it regularly according to the situation) |
3. Common Problems & Solutions
| PHENOMENON | REASONS | PROCESSING METHOD |
| Do not press up when pressing the handle | 1. The pressure relief valve knob is not tightened | 1. Tighten the pressure relief valve |
| 2. The sealing ring in the quick connector falls off | 2. Reinstall or replace with a new seal | |
| 3. The globe valve is not open | 3. Open the shut-off valve | |
| Minor leak | 1. The quick connector is not tightened | 1. Tighten the threaded joints everywhere |
| 2. The sealing ring is worn or aged | 2. Replace with a new sealing ring | |
| 3. The knob of the pressure relief valve is not tightened | 3. Tighten the pressure relief valve |
