This device is composed of basic vibration components that support the shaft rotation vibration components, the number of impeller blades, and their harmonic components. The excitation force is comparatively large in the equipment, and the sound production efficiency on the structural side is extremely high. In addition, the vibration isolation of the pump body is insufficient, so it is necessary to pay close attention to the surrounding pipe support and the wall penetration.
Large vibration peaks are generated in the shaft rotation component of the fan and the rotation speed of the motor. It offers a variety of installation locations and performance depending on its application, which includes large air volume, high static pressure, small air volume, and low static pressure. It is thought to be a difficult machine to use when determining appropriate vibration isolation devices. In addition, a total anti-vibration plan including ducts and chambers to be connected is required. Please contact us for product details.

Vibration peaks are generated in the axial rotation components of the compressor and the fan. These are often installed outdoors in close proximity, and their presence cannot be ignored. In addition, GHP is equipped with an engine and is a device that requires more attention than EHP. In recent years, there have been cases where it has been unitized to reduce the number of man-hours on site, and we also suggest obtaining a vibration isolator for the unit.

Vibration peaks occur in the shaft rotation components of the fan. Although the vibration of the machine itself is smaller than that of large equipment, there have been reports of many cases in which a desk or table is placed directly above the installation site and vibration disturbance occurs on the desk. This is one device that requires careful attention, because it is installed directly under living spaces.
This is a unit with built-in blowers that create a large air flow. The vibration of those blowers can generate both sensible vibration and solid sound at the same time.Since it is often installed adjacent to a space desperate to avoid vibration and noise, a high-performance anti-vibration device that can handle low to high frequencies is required. It is also necessary to take measures against the vibration of the outer skin of the casing and the propagation of vibration from the duct.
This device boasts a relatively large excitation force for an air conditioning unit. It features a typical compressor vibration, which produces vibration peaks in the compressor shaft as well as in higher order components. Equipment with high frequencies tend to cause solid noise. In addition, in recent years, there have been many cases in which modularization has been performed and multiple units have been installed together, so a detailed anti-vibration plan is required.
The main components of the absorption chiller-heater are the combustion wave of the gas burner and the rotation speed of the pump. This product has been mentioned as a selling point because of its low vibration, but the vibration force is unexpectedly large, so caution is required. In addition, although the turbo type is mainly composed of compressor vibration, the vibration force is quite large, and it is essential to take sufficient vibration damping measures when using it.
This device has relatively small excitation force for its body weight, and the main vibration components are its fan shaft rotation vibration, blade vibration, and motor shaft rotation vibration, with the blade vibration component being particularly large.Especially when dealing with cooling towers with a low axial frequency, it is of the utmost importance to take proper anti-vibration measures if the device is installed on the rooftop floor.
The generator is the largest source of vibration for building equipment and has an extremely large excitation force. Diesel engines and gas engines are characterized by the harmonic vibrations that are based on engine shaft rotation components, and gas turbines that generate high-frequency vibration components due to shaft rotation speed and pulsating flow components from the turbine. In addition, flues, silencers, and auxiliary machinery can also be sources of vibration, so a comprehensive anti-vibration plan is an absolute necessity. In addition, due to tsunami measures in recent years, it may have to be installed on a middle floor or the rooftop floor, so careful attention is required.
Harmonic vibration peaks, which are based on magnetostrictive vibrations that are twice the power supply frequency (50Hz or 60Hz), are generated, and since the pure tone is high, this is a device for which many malfunctions have been reported. Also, because of the machine's characteristics, it cannot be stopped easily, so it's important to come up with an anti-vibration plan in advance.
