3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 7785 and the following apply.
3.1
power reciprocating pump
reciprocating pump driven by independent rotary prime mover (including electric motor, internal combustion engine, steam turbine, etc.). Independent transmission devices (e.g. reduction gearbox, pulley, etc.) that are part of the pump shall be included in the pump range
3.2
ancillaries
independent parts and components (e.g. pulsation suppressing devices) installed on or near the pump, excluding the spare parts that do not need to be installed when the pump is first used
3.3
spare parts
used for replacing the parts and components that may be damaged (e.g. plungers) when the pump is in service
3.4
continuous operation
continuous operation for 8~24 h per day under rated conditions
4 Information confirmation
4.1 Information of the Buyer
When purchasing pumps from the Seller, the Buyer shall provide the Seller with necessary information, referring to the data sheet provided in Annex A. The Seller shall require the Buyer to provide all relevant information shall be considered, including use requirements, environmental requirements, operation requirements, etc.
4.2 Alternative items
The Buyer may put forward special requirements beyond the scope specified in this standard. The specific contents provided by the Buyer can be based on the agreement or purchase order, or Annex A.
