Alternatively, the valve core can get stuck by debris, or the spring can fail. Any of these issues will stop the pilot valve from working, preventing the pulse valve from opening or closing.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Control Circuit Problems:<\/strong>\u00a0Circuits can have open wires, short circuits, or poor connections. These problems prevent the pulse valve from receiving the electrical signal from the control unit. For example, vibration or friction can damage wire insulation, causing a short circuit. Loose terminals increase contact resistance and block signal transmission.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Diaphragm Damage:<\/strong>\u00a0The diaphragm is a key sealing and moving part. It suffers from constant impact by compressed air and frequent opening\/closing cycles. This leads to wear, aging, and cracking. A damaged diaphragm disrupts the normal pressure difference needed for operation, so the valve fails.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Insufficient Air Receiver Pressure:<\/strong>\u00a0The air receiver supplies the compressed air power. If its pressure is too low, the pulse valve cannot open, even if the solenoid and diaphragm are fine.

Both mean the coil is damaged and must be replaced.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Valve Core Flexibility Check:<\/strong>\u00a0With power off, manually push the valve core. Feel if it moves smoothly or gets stuck. A stuck core might mean internal debris or part wear. Disassemble the pilot valve for cleaning and inspection. Note the position and order of parts during disassembly. Use a special cleaner to remove oil and debris from the core and seat, ensuring free movement.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Wiring Check:<\/strong>\u00a0Carefully check if the wiring is secure. Look for damaged or aged wire insulation. Ensure terminals are tight, without looseness, oxidation, or corrosion, to guarantee signal transmission. Re-tighten loose terminals.

If pressure is low, check if the air compressor runs normally and delivers adequate pressure. Check for leaks in the air pipes. Apply soapy water to pipe joints and valve connections; bubbles indicate a leak that needs repair. Also, check if the air filter is clogged. A dirty filter element affects air flow and quality. Clean or replace it regularly.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Internal Air Passage Check:<\/strong>\u00a0With the pulse valve open, use a compressed air detector to check the air flow and pressure inside the valve. A noticeably weak or abnormal airflow at a specific point suggests a blockage or restriction. For example, if the outlet pressure is much lower than the inlet pressure (and air receiver pressure and external leaks are ruled out), the internal passage is likely clogged.

Start from the control unit&#8217;s output and measure the resistance between connection points along the line. An infinite resistance means an open circuit exists in that section. Find the break and fix it. Breaks can occur at damaged wires, loose terminals, or mid-line connections.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Voltage Detection:<\/strong>\u00a0When the control unit sends a signal, use a multimeter to measure the voltage at the solenoid pilot valve terminals. Ensure it matches the valve&#8217;s rated voltage. Low voltage may prevent the solenoid from working. Check the control unit&#8217;s output voltage and look for excessive voltage drop in the circuit. Long wires, thin gauges, or high contact resistance can cause significant voltage drop. Solve this by using thicker wires, optimizing the layout, or tightening terminals.<\/p><\/li><li><p class=\"ds-markdown-paragraph\"><strong>Control Unit Check:<\/strong>\u00a0Verify the control unit&#8217;s parameter settings. These include pulse interval, pulse width, and blowing sequence. Ensure they match the dust collector&#8217;s actual needs. Adjust them based on operational performance. Also, observe the control unit&#8217;s status for any fault alarms.
