INSTALLATION DEVICE FOR INSTRUMENTATION DEVICE OF STATIONARY ENGINE

摘要

A cylinder pressure sensor (18) is provided on the cylinder head (14) of a stationary gas engine (10), an instrumentation device installation device (30A) is provided on the engine frame (12), and an amplifier (22) that amplifies signals detected with the cylinder pressure sensor (18) is affixed to the instrumentation device installation device (30A). The instrumentation device installation device (30A) is formed with: a suspension means (32), comprising an anchoring plate (32a), which abuts a level surface (16) and is secured with bolts (34), an extension plate (32b) that is bent at a right angle with respect to the anchoring plate (32a), and a suspension plate (32c) that is bent at a right angle with respect to the extension plate (32b) and is parallel to the anchoring plate (32a); and coil springs (36), one end of which is connected to the suspension plate (32c) and the other end of which is connected to an anchoring band (38) that holds the amplifier (22). Because the amplifier (22) is suspended by the coil springs (36), vibration of the amplifier (22) can be suppressed.
