3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GB/T 5773 and
JB/T 7249 as well as the followings apply.
3.1 open-type single-stage reciprocating refrigerant compressor
A single-stage refrigerant compressor that relies on a prime mover to drive a shaft
protruding from the housing or other moving parts.
NOTE: Hereinafter referred to as "open-type compressor".
3.2 semi-hermetic single-stage reciprocating refrigerant compressor
A single-stage reciprocating refrigerant compressor in which the compressor and motor
are housed in a field disassembled housing.
NOTE: Hereinafter referred to as "semi-hermetic compressor".
3.3 hermetic single-stage reciprocating refrigerant compressor
A single-stage reciprocating refrigerant compressor in which the compressor and motor
are housed in a welded or brazed housing.
NOTE: Hereinafter referred to as "hermetic compressor".
3.4 single-stage reciprocating refrigerant compressor unit
A unit that is assembled by a single-stage reciprocating refrigerant compressor, and/or
prime mover and other accessories (such as an oil pump, oil cooler, oil separator, etc.)
5 Technical requirements
5.1 General requirements
5.1.1 The compressor (unit) shall be manufactured in accordance with the provisions of
this Standard as well as the drawings and technical documents approved by the
prescribed procedures (or the agreement between the user and the manufacturer).
5.1.2 For the compressor (unit) with safety valve, the valve action shall be sensitive,
air-tight, safe and reliable.
5.1.3 The compressor (unit) lubrication system shall meet the following requirements:
- When the ambient temperature is as high as 43°C or the cooling water temperature
is 33°C, the temperature of the refrigerating machine oil in the crankcase of the
semi-hermetic compressor (unit) shall not be higher than 80°C. For the open-type
compressor (unit), it shall not be higher than 70°C.
- For compressors (units) using a pressure lubrication system, the difference between
the oil pressure of the lubrication system and the pressure of the refrigerant in the
compressor crankcase shall ensure that the compressor (unit) works normally and
reliably when the oil circuit is not blocked. Compressors (units) using splash
lubrication shall ensure that the lubrication system can work reliably when the
motor is running forward or reverse (when reverse rotation is allowed).
- The oil leakage at the shaft seal of the open-type compressor (unit) shall not exceed
0.5 mL/h.
5.1.4 The outer surface of the compressor (unit) shall be clean. The paint layer shall
adhere firmly. There shall be no defects affecting the appearance quality.
5.2 Safety requirements
The safety requirements for the compressor (unit) shall comply with the provisions of
GB/T 9237 and GB 4706.17.
5.3 Performance requirements
5.3.1 Air tightness
The airtightness of the compressor (unit) shall meet the following requirements:
- When the leak detection medium is dry, clean air or nitrogen, there shall be no
leakage at all parts of the compressor (unit) or its housing and other pressure parts.
- When the leak detection medium is helium, there shall be no leakage when the
pressure parts such as the compressor (unit) or its housing are tested with a
6.1.3 The instruments and meters used for the test shall pass the inspection by the legal
metrology inspection department and be within the validity period.
6.1.4 In addition to the test instruments and meters specified in this document, the type
