Title:
FLUID MACHINE
Document Type and Number:
Japanese Patent JP2020101093
Kind Code:
A
Abstract:
To solve such a problem that abnormality cannot be detected even though abnormal heating is caused when driving in a condition where the temperature of a compressor is not increased.SOLUTION: A fluid machine includes a fluid machine body, a motor driving the fluid machine body, a temperature sensor measuring the temperature of the fluid machine body, and a control part controlling the fluid machine body. The control part changes a temperature threshold value on the basis of at least one of a pressure of fluid the fluid machine body discharges and a frequency of voltage input to the motor, and makes notification when the temperature of the compressor body detected by the temperature sensor exceeds the temperature threshold value.SELECTED DRAWING: Figure 2
