1 Subject content and scope of application
Power source to power
This standard defines the detailed value of the dynamics of the auxiliary equipment in the engine room of ships such as steam turbine generators, generators, air compressors, pumps, ventilators, refrigerators and separators,
This standard is applicable to the test value of the dynamic density limit of the auxiliary equipment of the old age under normal working conditions, this standard is not applicable to the power source, diagnosis Fault. Research local vibration or other research at present: 2 Reference standards
GBI1?C6-89 Ship energy auxiliary machine detection vibration density measurement method 3 Measurement standard
This standard adopts the equivalent vibration of the whole machine as the evaluation of machine vibration, and its value is calculated according to formula (1), ++
V equivalent vibration degree mm/s;
-The root mean square value of the grip speed in the three directions of X, Y.2 respectively +mm/s; Fx.Vr.V.
4 Measurement method
The balance points in the two directions of X, Y2 respectively
The vibration measurement base force is carried out in accordance with the provisions of GB11706. 5 Measurement conditions
5.1 The vibration measurement of the machine shall be carried out when it is in the normal running state. 5.2 For the machine with variable conditions, the vibration measurement shall be carried out at the normal state of all working points. 6 Installation
6.1 The machine with rigid support shall be installed on the equivalent end of the ship for measurement. The natural frequency of the elastic support shall be less than one-fourth of the excitation frequency of the machine
6.2 The machine with rigid support shall be installed on the equivalent rigid support frame for measurement. The wave frequency of the rigid support frame shall be greater than the main frame of the machine. National Technical Supervision Bureau 1996-0-25 approved 1997-01-01 implementation #
Classification and rating of dynamic intensity

Machinery and mechanical equipment are divided into two types: 7
Class 1
Class 2
Class 4 - Rotating machines with small power; Rotating machines with power of 16-~7Shw, fans with power less than 15kw and small power greater than: Compound machines with power less than 75kW, reciprocating machines with power less than 100w.
7.? The evaluation of the dynamic performance of auxiliary machinery in the engine room is divided into four levels: Class A - good working condition, Class B - acceptable working condition, Class A - acceptable working condition, and Class B - acceptable working condition. 1.3 Evaluation and classification of dynamic intensity levels of auxiliary machinery in the engine room before installation: The judgment of the dynamic intensity levels of auxiliary machinery in the engine room under elastic support installation mode shall be based on Table 1. The judgment of dynamic intensity levels of auxiliary machinery in the engine room under brush support installation mode shall be based on Table 2. Table 1 Thermal intensity. mm/
