1. Names of Parts 1.1 Names of Parts 1.2 Contents of Package The main devices and the accessories are packed in different cases. Open the top part of the corrugated fiberboard case and check if the devices and cabinet are not damaged and if accessories are all contained in the package.
2. Principles of Operation The Yamada Air-powered Pump is a reciprocating type that is driven by compressed air. The pump consists of an air motor to drive the pump and a lower pump to draw up the material as shown in the figure at right.
3. Preparations before Operation 3.1 Setting a Pail (Fig. 1) 1) Release the 3 clasps on the top of the cabinet upward, and the lid can be removed together with the pump. 2) Take out the follower plate in the cabinet. <Note>...
3.3 Operating the Equipment CAUTION - The maximum supply air pressure of this machine is 0.7 MPa. Using the machine with a supply air pressure exceeding this limit will lead to death or bodily injury or physical damage due to machine breakage.
4. How to Operate the Machine CAUTION - The supply air pressure should be 0.7 MPa or less. If the primary pressure is more than 0.7 MPa, adjust the pressure to 0.7 MPa or less. Fig. 6 - After the end of daily work or when the machine is not operated for a long time, be sure to shut off the supply air and bleed the internal pressure of the pump, hose, and gun.
5. Maintenance and Inspection 5.1 Troubleshooting and Corrective Measures If the pump operation becomes unstable or trouble is caused to its grease discharge during operation, make a check according to the following procedure. Symptom Cause Contents of inspection and corrective measures The pump cannot be Check if the air regulator Check if the valve in the...
5.2 Maintenance and Inspection For lubrication of the pump, perform oiling once every 10 days with lubricating oil. (Fig.9) Apply the lubricating oil as following. Fig. 9 1) Remove the air regulator. 2) Inject a few drops of lubricating oil (approx. 0.5 mL) into the air supply port as shown in the figure at right.
5.3 Disassembly and Assembly When the pump operation becomes defective or stops, do not disassemble the pump thoughtlessly but judge the condition carefully by referring to the item pertaining to <Troubleshooting and Corrective Measures>. The air motor that is not brought into direct contact with the material becomes defective rarely, so it does not need to be disassembled.
5.3.2 Disassembling and inspecting the lower pump 1) Fix the suction tube on the vise and set a pipe wrench on the booster cover. Unscrew the suction tube and remove the spring pin, nut, and shovel. (Fig. 11) 2) Likewise, set a pipe wrench on the valve case and unscrew it.
