GB/T 25637.1-2010Building construction machinery and equipment -- Concrete mixers -- Part 1: Vocabulary and general specifications (English PDF)

Foreword

GB/T 25637 "Building construction machinery and equipment concrete mixer" is divided into two parts.

--- Part 1. Terminology and commercial specifications;

--- Part 2. stirring performance test procedures.

This section GB/T Part of 125,637.

This part identical with ISO 18650-1:2004 "Building construction machinery and equipment - Concrete mixers - Part 1. Terminology and commercial Specifications "(in English).

This section is equivalent translation ISO 18650-1:2004.

For ease of use, this section made the following editorial changes.

a) "This part of ISO 18650-1" be replaced by "GB/T 25637 in this section";

b) Delete ISO 18650-1:2004 Foreword;

c) For ISO 18650-1:2004 international standard reference has been adopted as the equivalent of our national standards, the reference section of these Instead of the corresponding national standards with international standards (see Part 2);

d) Since this section does not appear ISO 18650-1:2004 references listed in the file, so remove it;

e) For ISO 18650-1:2004 original editorial errors by the ISO/TC195/SC1 contact the Secretariat confirmed that this section the following modifications.

1) two column item 5.3.3.1c) of the latter two of "relevant size See 5.2 and Figure A.8 and A.102)" and the "optional Member. feed hopper assembly, the whole cage, water flow meter apparatus (including filters and stop valve), the volume of metered water supply means and cement, aggregate weighing device. "Is replaced by a column items, namely as d) and e) items;

Definition 2) 3.11 to "rated capacity equal to the capacity of the dry material was stirred Vc or ready-mixed concrete Vu capacity";

3) Figure A.4 job length L0 state boundaries marked wrong size, the size limit on the right to the same L1.

This part is proposed by China Machinery Industry Federation.

This part of the National Construction Machinery and Construction Equipment Standardization Technical Committee (SAC/TC328) centralized.

3 Terms and Definitions

GB/T 18576 and the following terms and definitions set forth in the application of this section.

Vertical shaft concrete mixer pan-typeconcretemixer Centerline axis vertical stirring device or mixing tank rotates around the fixed and rotating compulsory mixer.

Feeding time t1 chargingtime A batch of concrete mixing materials into the mixer within the duration.

Note 1. referred to here as the mixer batch mixer.

Note 2. Feeding time t1 in seconds (s).

Stirring time t2 mixingtime stirred material from the feed end to the stirred mixing of materials between the time ends.

NOTE. Mixing time t2 in seconds (s).

Stirring time t2 mixingtime stirring the material in the stirred tank stay duration.

Note 1. The continuous mixer stirring time is calculated as follows.

t2 = mc/qm

Where.

mc --- stirred tank mixing quality materials, in kilograms (kg);

qm --- stirring material on material flow, in kilograms per second (kg/s).

Note 2. stirring time t2 in seconds (s).

Discharge time t3 dischargingtime from the beginning to the expected duration of the discharge end.
