If your YAMADA Water Pump isn't stopping, it might be due to a leak in the delivery pipe. Try retightening any loose parts. Alternatively, there could be a leak in the lower pump, caused by loosened connections or damage to the o-ring, backup ring, or packing.
How to troubleshoot a YAMADA 140 that doesn’t run?
If your YAMADA Water Pump isn't running, several factors could be the cause. Here are a few things to check: * Ensure the compressor is turned on. * Verify that the valve on the air piping is open. * Confirm the air pressure setting is at least 0.2MPa. If it's lower, adjust it accordingly. * Check that the valve on the material outlet is open. * Make sure frost isn't forming inside the silencer by using dry air. Additionally, inspect the O-ring on the sliding part of the air piston for wear. If there's an air leak from the silencer, replace any worn or damaged parts.
Why is there an air leak from the air motor of my YAMADA 140 Water Pump?
If you notice air leaking from the air motor of your YAMADA Water Pump, the possible causes are loose fasteners or worn out O-rings and packings. Try retightening any loose parts first. If the leak persists, replace any worn O-rings or packings.
Why is my YAMADA 140 leaking material from the lower pump?
If your YAMADA Water Pump is leaking material from the lower pump, first check if any fasteners are loose and retighten them. If the leak continues, the O-ring, backup ring, or packing may be damaged and need replacement.
What to do if my YAMADA 140 Water Pump cannot pump out material?
If your YAMADA Water Pump isn't pumping out material, and the upward movement of the plunger is faster, check the seat surface of the piston valve for defects (wear or foreign material) and remove any foreign objects. Also, inspect the packings for damage and replace if necessary. If the downward movement of the plunger is faster, decrease the air pressure until material comes out to the upper limit of normal operating pressure. Also, if the connecting rod connecting air motor and lower pump is completely separated from air motor, inspect inside lower pump first, then replace damaged part, and retighten each part.
Why does my YAMADA 140 have an air leak from the silencer during shutdown?
If air leaks from the silencer of your YAMADA Water Pump during shutdown, it could be due to a foreign object caught between the block and valve seat in the valve body. Remove the foreign object. Alternatively, the seating part may be worn out, requiring replacement.
What causes a YAMADA Water Pump to not run and leak air from the silencer?
If your YAMADA Water Pump isn’t running and air is leaking from the silencer, there might be a foreign object caught between the spindle and valve switcher in the air motor. Remove any foreign objects. Alternatively, there could be damage preventing the sliding movement of parts, in which case you should replace the damaged part.
Why doesn't the lift on my YAMADA 140 move up or down?
If your YAMADA Water Pump lift doesn’t move up or down, make sure the compressor is on and the air supply is turned on. Also, check that the air pressure is set to 0.4MPa. Ensure you are using a straight side pail, because an uneven pail surface can cause the lift to not move. Finally, inspect the cylindrical section of the lift air cylinder for dents and replace the part if necessary.
What to do if YAMADA Water Pump doesn’t draw material at first use?
If your YAMADA Water Pump isn't drawing material during the first operation, the pump operating speed might be too fast, preventing the lower pump suction from keeping up. Adjust the pump speed to 5-8 seconds per cycle until the material is pumped out.
Why does the material from my YAMADA 140 Water Pump contain air bubbles after bleeding?
If the material from your YAMADA Water Pump contains air bubbles even after bleeding, ensure that you are using a JIS-approved pail, as the internal diameter of your current pail may be too large. Also, check that the air release plug is secure and replace the packing of the inductor plate if it's deteriorated. Finally, retighten any loose fasteners and replace any damaged O-rings or backup rings.
