Precision of Electric Heater Assembly Process Specification
Ensuring the assembly precision of electric heaters is essential for the machine to have normal working performance. The assembly precision mainly includes the mutual fit precision between parts, relative motion precision, and mutual position precision.
( 1 ) Fit precision
Refers to the fit quality and contact precision between mating surfaces, such as whether the fit is clearance or interference, the form of contact surfaces, etc.
( 2 ) Motion precision
Refers to the precision in motion direction and relative motion speed between parts with relative motion in the electric heater, such as transmission precision and rotational precision.
( 3 ) Position precision
Refers to the distance precision and mutual position precision between related parts in the electric heater, such as distance dimensions and accuracy requirements between parts, parallelism, various runouts, perpendicularity, and coaxiality.
In the hot oil system, the fit between the flange and the pipe is a clearance fit.
The assembly precision of the machine ultimately affects the precision of the machine during actual operation, i.e., working precision. For example, the assembly precision of a machine tool will directly affect the precision of parts processed on this machine tool.
