GB/T 26507-2019Petroleum drilling and production equipment—Ground oil-gas transportation pump (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 26507-2011 "Ground oil and gas mixed pumps for drilling and production equipment in the oil and gas industry". This standard Compared with GB/T 26507-2011, the main technical changes are as follows.

--- The name of the standard was revised to "Ground Oil-Gas Hybrid Pumps for Oil and Gas Drilling and Production Equipment";

--- Increased model representation (see Chapter 3);

--- Modified the rated discharge pressure range in the basic parameters (see 4.5, 3.2 of the 2011 version);

--- Modified the range of medium viscosity and gas content of the pump under the normal operating environment of the pump (see 4.6, 3.6 of the 2011 version);

--- Revised the regulation of noise value (see 4.9, 3.9 of 2011 version);

--- Revised the regulation of pump volumetric efficiency (see 4.10, 3.10 of the 2011 edition);

--- Revised the regulations on pump efficiency (see 4.11, 3.11 of the 2011 edition);

--- Added rules for pump material selection when pumping corrosive gaseous media containing hydrogen sulfide and other materials (see 4.22);

--- Increased the provisions of the pump flow and shaft power tolerance (see 4.23);

--- Increased the provisions of the viscosity of the oil medium during type testing (see 5.1.1.2);

--- Increased records of gas flow and liquid flow in test values (see Appendix D);

--- Increased the oil and gas mixed pump system diagram (see Appendix F).

1 Scope

This standard specifies the model and technical requirements for the designation of oil and gas mixed-use pumps for the oilfield (twin-screw mixed-use oil and gas pumps, hereinafter referred to as "pumps"). Requirements, test methods, judgment rules, complete sets, marking, packaging and storage.

This standard applies to the design, inspection and use of pumps.
