Introduction

GB/T 6075.1 is the basic document, which describes generally measured vibration on non-rotating parts of various types of machine vibrations Evaluation begging. GB/T 6075 this part of the assessment in the industrial machinery bearings, housings or measuring vibration intensity on a support site provides special Guidelines.

Vibration assessment of the machine there are two criteria, the first criterion is to consider the magnitude of vibration, the second criterion is to consider changes in the vibration magnitude.

However, these two criteria must be taken not as the sole basis for determining vibration intensity. For some types of machines, measuring shaft Vibration determination is relatively common, shaft vibration measurements and criteria, see ISO 7919-1 [1] and ISO 7919-3 [2].

1 Scope

GB/T 6075 This section gives guidelines for site assessment to measure vibration levels, the Code applies to power greater than 15kW, transport Line speed in 120r/min to 15000r/min units.

This section covers the machine.

--- Power less than 50MW turbine;

--- Steam turbine power greater than 50MW, but the speed is less than 1500r/min or greater than 3600r/min (ie, not including ISO 10816-2 Covered unit);

--- Rotary compressor;

--- Power less than 3MW of industrial gas turbines;

---generator;

--- Various types of motor;

--- Blower or fan.

NOTE. Vibration criteria in this section generally apply only to the rated power of more than 300kW wind turbine or flexible support of the fans. When conditions permit, prepared to recommend Other types of fans, including those using lightweight sheet metal structure of the fan. Prior to this, the manufacturer and the user can be based on previous experience running knot If both parties agree to accept the vibration classification, see ISO 14694 [4].

The following machines do not fall within the scope of this part.

--- Power greater than 50MW turbine generator installed on land, its speed is 1500r/min, 1800r/min, 3000r/min, 3600r/min (see ISO 10816-2);

--- Power greater than 3MW gas turbine (see ISO 10816-4);

--- Hydroelectric and pumping plants (see ISO 10816-5);

--- Reciprocating machine coupled machines (see ISO 10816-6);

--- Motor rotor includes an integrated power pumps, for example, an impeller mounted directly on the motor shaft or rigidly connected thereto (see ISO 10816-7);

--- Rotary compressor (such as screw compressors);

---Reciprocating compressor;

--- Reciprocating pump;

--- Electric submersible pumps;

--- Wind turbine.

Vibration criteria in this section apply to work within the rated speed, stable operating conditions, the machine bearings, housings or machine base site Wide band vibration measurements. They relate to the acceptance tests and operation monitoring. This part of the evaluation criteria used for continuous and non-continuous monitoring Happening.

This section contains the machine with gears or rolling bearings, but does not involve the diagnostic evaluation of these gears or rolling bearing state.

This section applies only to the vibration generated by the machine itself, and not to pass by external vibration source to the vibrating machine.
