Challenges and Solutions in Operating Large-Flow Pressure Testing Pumps

Issues Encountered and Solutions Implemented During Operation of Large Flow Pressure Test Pumps

Hongyuan Machinery, a leading manufacturer of high-flow pressure testing pumps, specializes in the research and production of pressure testing pumps. With over a decade of distribution experience, Hongyuan has evolved from producing simple manual pressure testing pumps to offering a wide range of models with various applications. Amidst the challenges, the company has achieved remarkable success in the pressure testing pump industry. The company's pressure testing pump technology also stands out among its peers.

Troubleshooting issues with pressure testing pumps is a common occurrence. Today, we'll delve into the reasons behind the 4D pressure testing pump not producing water and provide solutions. The principle of the 4D pressure testing pump involves four plunger-type pumps, with two high-pressure pumps and two low-pressure pumps. After powering on, the motor operates normally, the turbine and plungers run smoothly, but there's no water in the high-pressure pipe, allowing us to directly diagnose the problem. Here's how to proceed: 1. First, check for any blockages in the filter screen and clean it. 2. Inspect if the water intake of the water tank is above the water level; if so, add an appropriate amount of water. 3. Verify that the pressure relief valve is tightly closed to ensure no leakage. 4. Ensure the high-pressure pipe is vented for 5 minutes. If these issues are resolved and the pump still doesn't produce water, it's likely due to the low-pressure cylinder not filling with water. This situation often occurs when the liquid used for pressure testing is not pure enough or too thick. It's crucial to clean the pressure testing pump after use to prevent issues with the high-pressure pipe. When using clean water as the pressure medium, always add a corrosion inhibitor to the water tank to prevent rusting and subsequent issues with the high-pressure pipe.
