Gas liquid booster pump is a device that converts the energy of compressed gas into liquid pressure, widely used in situations where high-pressure liquid is required. Its working principle is to use the pressure of gas to achieve the required high pressure of liquid through a pressurization device. The main features include easy operation, high safety, no need for power supply, low maintenance cost, and high energy efficiency.
Gas liquid booster pumps are commonly used in industrial fields, such as pressure testing of hydraulic systems and other applications that require high-pressure liquids. They are typically driven by compressed air and use gas driven hydraulic systems to provide higher liquid pressure.
Some common malfunctions may occur during the use of gas-liquid booster pumps. Understanding these faults and their troubleshooting methods can help ensure the normal operation of the equipment. Here are some common faults and corresponding solutions:
1. The pump cannot start or operates slowly
reason:
It may be due to insufficient gas source pressure, blocked gas path, or malfunction of pneumatic components. The control valve is not operating correctly, and there is air in the liquid system.
Handling method:
Check the air source pressure to ensure it meets the required pressure range of the equipment. Check the air circuit, clean the blocked parts, and ensure that the pneumatic components are working properly. Check and re operate the control valve. Check the liquid system and eliminate air to ensure that there are no bubbles in the liquid system.
2. Insufficient output pressure
reason:
The gas source pressure is insufficient or unstable. Improper selection of boost ratio leads to internal leakage in the hydraulic system.
Handling method:
Ensure that the air source pressure meets the requirements of the pump and check if the air source is stable. Check the boost ratio of the booster pump to ensure it matches the requirements. Check the hydraulic system, especially the seals, and repair the leaking parts. Adjust the liquid temperature to within the recommended range of the equipment.
3. The pump frequently starts or stops
reason:
The gas supply is unstable. Improper setting of pressure switch or controller. Leakage or unstable control of the pressure relief valve.
Handling method:
Check and stabilize the gas supply. Adjust the set value of the pressure switch or controller. Check if the pressure relief valve is working properly and replace it if necessary.
4. Abnormal noise occurs during pump operation
reason:
The air source pressure is too high or too low, and the pneumatic components are faulty or worn.
Handling method:
Adjust the gas source pressure to the recommended range. Check the status of pneumatic components and replace damaged parts if necessary.
5. Liquid leakage
reason:
Seals are aging or damaged, pipeline connections are loose, hydraulic cylinders or other components are damaged.
Handling method:
Replace aging or damaged seals. Tighten the pipeline connection to ensure no looseness. Check the hydraulic cylinder and other components, and repair or replace them if necessary.
6. The pump cannot reach the expected pressure
reason:
Pneumatic valve not fully opened, hydraulic oil contamination or oil circuit blockage. Wear of pistons or other moving parts.
Handling method:
Ensure that the pneumatic valve is fully open. Check and replace hydraulic oil, clean the oil circuit. Check the wear of moving parts and replace them if necessary.
Through regular maintenance and inspection, many malfunctions of gas-liquid booster pumps can be prevented. If the problem persists, it is recommended to contact professional maintenance personnel or manufacturers for further diagnosis and repair.
