Description
Units of electric pumping stamps 1x-E65-40-200 (subsequently units) are designed to pump pure neutral fluids with kinematic viscosity up to 30*10-6 m²/s, having solid inclusions of not more than 0.2 mm, the volumetric concentration of which is not more than 0, 1 % with the temperature of the pumped fluid from minus 40 to +90 ° C, a density of not more than: 1850 kg/m³, including pure lightly boiling liquids (such as ammonia) with a density of up to 700 kg/m³.
Scope- explosion-fire hazardous zones of the 1st and 2nd classes of premises and external plants in accordance with TR TS 012/2011; GOST 31438.1; GOST 12.1.011 and other regulatory documents, in which pairs, gases and fogs of pumped liquids form explosion-hazardous mixtures of categories IIa with air; IIB and groups T1, T2, T3, T4 depending on the temperature of the mixture ignition, with the exception of liquids with oxygen dissolved in them, detonating molten metals, liquefied gases, radioactive liquids and other similar media.
Environmental Conditions:
-Temperature from minus 50 to plus 45 ºС;
-pressure from 80 to 110 kPa (from 0.8 to 1.1 bar);
-climatic execution U, placement category 2, 3 GOST 15150.
The conditional designation of the unit in order, correspondence and in another documentation is adopted in accordance with TS TS 010/2011, 012/2011 and ST PC00218035-001-2011 executions and category of accommodation according to GOST 15150.
Example of the designation:
1x-E65-40-200-A-55-U3 EX II GB C/B IIBT4 X -50 ºС ≤ TO ≤ +45 ºС ST PC00218035-001-2011, where:
- 1 -modernized;
- x -centrifugal chemical horizontal console pump;
- E -designation of executive and fire hazardous production;
- 65 -input diameter in mm;
- 40 -exit diameter in mm;
- 200 -nominal conditional diameter of the working wheel in mm;
- A -the symbol of the material of the flow of the pump;
- 55 -type of shaft seal (double end seal-type 153/153 or analogue);
- U -climatic execution;
- 3 -Placement category during operation.
- EX -a special explosion safety sign;
- II -Equipment group;
- GB -the level of explosion protection;
- C/B -type of explosion protection.
-
IIB -the group and subgroup of equipment in accordance with the category of explosion hazard of the mixture for which the equipment is intended.
Equipment marked as IIB is also suitable, also for use where the equipment of the subgroup IIA is required. - T4 -the classification of equipment depending on the temperature class of the explosive gas mixture and designates the maximum surface temperature ºС at which the unit can be operated. < Br Style = "Box-Sizing: Border-Box;" /> Equipment marked as T4 is also suitable, also for use where the temperature class T3, T2, and T1. equipment is required.
- x -designation of additional information on the installation, use and maintenance of equipment. Since the actual maximum surface temperature does not depend directly on the equipment, but mainly on operating conditions (such as heated (hot) fluid pumped by the pump).
-
-50 ºС ≤ +45 ºС -the range of ambient temperatures at which the unit can be operated.
