Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 7785-1987 "reciprocating pump classification and terminology."
This standard compared with GB/T 7785-1987, in addition to editorial changes outside the main technical changes are as follows.
--- To increase the mechanical diaphragm pumps, hydraulic diaphragm pumps, pneumatic diaphragm pump (see 3.2.3.1 ~ 3.2.3.3);
--- Modify radial pump (see 336, 1987 Edition 2.3.6.);
--- Increased turbocharger (see 3.5.2.2);
--- Increase booster (see 3.6.6);
--- Increased fertilizer pump (see 3.6.7);
--- Increase the injection pump (see 3.6.8);
--- Increasing the profile pump (see 3.6.9);
--- Increased fracturing pump (see 3.6.10);
--- Increasing the pump (see 3.7.2);
--- Increase pump impurities (see 3.7.3);
--- Increased emulsion pump (see 3.7.5);
--- Increasing the clearance volume/volume of the internal volume displacement, geometric volumetric displacement (see 4.2.13.1 ~ 4.2.13.3);
--- Increase seat velocity, flow rate of the valve (see 4.2.23,4.2.24);
--- Increased cross-sectional area (see 4.2.25);
--- Increased slipstream (see 4.3.3);
--- Increasing the safety valve set pressure, the safety valve of a pressure build-up (full pressure), the pressure relief valve is reset, back pressure relief valve (see 4.3.4.11 ~
4.3.4.14);
--- Increased pulse pressure, inflation pressure (see 4.3.4.15,4.3.4.16).
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee pump (SAC/TC211) centralized.
This standard is mainly drafted by. Hefei General Machinery Research Institute, Zhejiang University.

Reciprocating pump Classification and Terminology
1 Scope
This standard specifies the reciprocating pump commonly used classification and terminology.
This standard applies to reciprocating pump design, manufacturing, trade, the development of other relevant standards, preparation of relevant technical papers and reports, write or turn
Translated literature books, teaching materials, samples and technical exchanges.
2 term basis
2.1
Reciprocating pump reciprocatingpump
Reciprocating pump is used to change the volume of the working chamber through the working chamber element (piston, piston, diaphragm, bellows, etc.) reciprocating displacement, so that
A mechanical fluid is delivered by the determined flow rate discharged. Reciprocating displacement element of energy from various prime mover. Working chamber inlet and outlet
Port and with the atmosphere of the site, by the isolation element is controlled.
3 taxonomy terms
3.1 Press the piston (plunger) number of points
3.1.1
Single pumps simplexpump
Only one or the equivalent of a plunger (piston) pumps.
3.1.2
Double pump duplexpump
There are two or equivalent to two pistons (piston) pumps.
3.1.3
Triple pump triplexpump
There are three or the equivalent of three pistons (piston) pumps.
3.1.4
Multiple pumps multiplexpump
There are four or more, or the equivalent of more than four pump piston (plunger) of. The number of multiple pumps can also be the actual piston (plunger) were named
Quadruple pump (quadruplexpump), five of the pump (quintuplexpump), six of the pump (sextuplexpump), seven of the pump (septuplex
pump), nine of the pump (nonuplexpump).
3.2 according to the principle and structural characteristics of the fluid end points
3.2.1
Piston pump pistonpump
A seal of the pump working chamber to do a linear reciprocating displacement components.
3.2.2
Piston plungerpump
No seals on the working chamber to do a linear reciprocating displacement components, but not on the movable member has a seal pump.
