吉田高圧機械 List of Products and Services

This device can pressurize helium and perform airtight testing on test specimens. After the airtight test, it also has the function of recovering helium into a storage tank. Additionally, since it uses a vacuum pump for evacuation, the recovered helium can be reused while maintaining its purity. The air-driven pump used in the device is compact and allows for easy maintenance of the high-pressure components.

This booster [Gas booster (for gases): Max 130MPa, Compressor (for liquids): Max 700MPa] is an air-driven high-pressure pump that can produce high-pressure gases using only factory air (Min: 0.4MPa). It can be used for airtight testing and pressure testing of tubes, hoses, pressure gauges, valves, safety valves, etc. Our booster has undergone various improvements, and particularly, the unique double-check valve excels in pressure retention, resulting in reduced operating cycles and improved durability, which has received positive evaluations. We encourage you to consider it. 【Features】 ■ Unique double-check valve excels in pressure retention ■ Reduced operating cycles and improved durability (less frequent maintenance) ■ Can be tested by the High-Pressure Gas Safety Association (KHK) ■ Double the high-pressure gas production per cylinder (2 cylinders) ■ Achieves target pressure with a single booster through two-stage compression *For more details, please refer to the PDF document or feel free to contact us.

• Pneumatic Equipment

The "Impulse Test Machine (Impact Testing Machine)" is a pulsating test device that applies repeated water pressure to the test medium. It is effective for durability testing of hoses, tubes, pressure gauges, valves, and more. This product is not only compact due to its air-driven source, but it is also easy to maintain, which has been appreciated by our customers. Additionally, it is characterized by having only five components that need to be replaced every one million cycles or annually: high-pressure cylinder, high-pressure seal, wear ring, die stud, and O-ring. (It is recommended to overhaul the booster every three years.) 【Features】 ■ Applies repeated water pressure to the test medium ■ Compact body due to air-driven source ■ Easy maintenance ■ Only five components need to be replaced every one million cycles or annually ■ Complies with JIS S3200 testing method *For more details, please refer to the PDF materials or feel free to contact us.
