Electromagnetic pulse valve is the core component of the dust removal system in industrial dust removal equipment. Its operational stability directly affects the dust removal efficiency and the overall working conditions of the dust removal equipment, thereby ensuring the continuous operation of industrial production and meeting environmental standards. This article summarizes the daily operation and maintenance standards, common troubleshooting ideas, and practical disposal methods of electromagnetic pulse valves, providing professional reference for foreign trade practitioners and equipment maintenance personnel.

1、 Daily operation and maintenance standards

The core of daily operation and maintenance is "anti blocking, anti leakage, and anti wear", focusing on vulnerable parts and key parameters to reduce the occurrence rate of failures. The specific specifications are as follows:

1. Regular inspection: Check the appearance of the electromagnetic pulse valve daily to confirm that there is no damage or air leakage, and that the wiring terminals are tightened without looseness; Monitor the gas source pressure and injection frequency weekly to ensure compatibility with the equipment and avoid damaging the valve due to high/low pressure; Clean the dust inside the valve and spray nozzle every month, and check the aging condition of the sealing ring.

2. Air source maintenance: Ensure that the air source is dry and clean, regularly clean the oil-water separator in the air source pipeline, filter out moisture and oil, and prevent moisture and oil from entering the valve interior, causing valve core jamming and sealing failure.

3. Environmental protection: Avoid electromagnetic pulse valves from being exposed to high temperature, high corrosion, and high dust environments for a long time, and install protective covers if necessary; Prevent the valve from mechanical collision and prevent deformation of the valve core and body.

4. Standardized operation: Before starting the dust cleaning system, confirm that the air source pressure meets the standard; After shutdown, promptly turn off the gas source and discharge the residual gas inside the valve to avoid long-term pressure damage to the seals; It is strictly prohibited to adjust the spray pressure and cycle in violation of regulations.

5. Spare parts management: Reserve commonly used vulnerable parts (sealing rings, valve cores, coils), regularly check the status of spare parts, ensure quick replacement in case of failure, and shorten downtime.

2、 Common troubleshooting and disposal methods

The troubleshooting follows the principle of "first intuitive, then deep, and first easy, then difficult". Priority is given to troubleshooting areas such as gas sources, wiring, and seals that are prone to problems. Specific faults and their solutions are as follows:

（1） Fault 1: Electromagnetic pulse valve does not operate

Troubleshooting approach: First check the power supply and wiring, then investigate the coil and air source, and finally check for any stuck valve core.

Disposal method:

1. Check the power wiring, repair damaged lines, tighten loose terminals, and confirm that the power voltage matches the rated voltage of the valve;

2. Check if the coil is burnt out (measured with a multimeter), and replace it with a coil of the same model if it is burnt out;

3. Check the pressure of the gas source to ensure it meets the standard, clean the blockages in the gas source pipeline, and discharge water and oil stains;

4. Disassemble the valve and clean the dust and debris on the valve core. If the valve core is severely worn or stuck, replace it.

（2） Fault 2: Severe leakage of electromagnetic pulse valve

Troubleshooting approach: Focus on inspecting the sealing ring, valve body sealing surface, and nozzle, followed by checking if the valve core is not tightly closed.

Disposal method:

1. Replace aging or damaged sealing rings, clean up debris on the sealing surface, and ensure that the seal fits snugly;

2. Check whether the nozzle is deformed or damaged, and repair or replace it in a timely manner;

3. Check if the valve core is worn or deformed, which may cause loose closure. If necessary, replace the valve core;

4. Tighten the valve connection bolts to avoid air leakage at the connection.

（3） Fault 3: Weak blowing and poor dust cleaning effect

Troubleshooting approach: Prioritize investigating the pressure of the gas source, then check for blockages in the spray pipe and valve opening, and finally investigate the wear of the valve core.

Disposal method:

1. Adjust the air source pressure to the specified range, clean the oil-water separator, and ensure that the air source is clean;

2. Clean up the dust and blockages inside the spray pipe, adjust the position of the spray pipe to ensure even spraying;

3. Check the valve core opening. If the valve core is worn and causes insufficient opening, replace the valve core;

4. Adjust the spraying cycle and duration to meet the requirements of dust cleaning.

（4） Fault 4: Frequent or stuck valve action

Troubleshooting approach: Investigate the control circuit, spray cycle settings, and then check for stuck valve cores and coil faults.

Disposal method:

1. Check the control module, adjust the blowing cycle to a reasonable range, and repair the control circuit fault;

2. Disassemble the valve, clean the valve core of dust and debris, and apply an appropriate amount of lubricating grease (to avoid oil pollution of the gas source);

3. Check the coil. If the coil has poor contact or aging, replace it.

3、 Core points of operation and troubleshooting

1. The faults of electromagnetic pulse valves are mainly caused by unclean gas sources, aging seals, and stuck valve cores. Normalized operation and maintenance can effectively avoid them;

2. Before troubleshooting or disassembling the valve, it is necessary to cut off the power supply, turn off the gas source, discharge residual gas, and take safety precautions;

3. When replacing components, it is necessary to choose accessories that match the prototype number to avoid secondary failures caused by model mismatch;

4. Regularly summarize the fault patterns, optimize the operation and maintenance cycle, and adjust the inspection frequency based on dust concentration and equipment load.

Summary: The daily operation and maintenance of electromagnetic pulse valves focus on gas source purification, regular inspections, and standardized operation. Common faults can be quickly identified and resolved through the sequence of "power source gas source valve core seal". Regular operation and timely troubleshooting can extend the service life of electromagnetic pulse valves, ensure the stable operation of dust removal equipment and cleaning systems, and provide reliable support for industrial dust control.
