Pump w, mv

Pump w, mv

They are used, as a rule, in enrichment factories for hydraulic exploration crushed products. The pumps of the group W, MV, etc. are made on the basis of our modern constructive solutions, but the geometry of the prototype part corresponds to the analogues of the leading world manufacturers. These pumps have a high efficiency (up to 82%), but from the analogues of the production of Western companies, they favorably differ in reinforced design, increased reliability, loyalty to the “domestic” approach to equipment maintenance, “indestructibility” and “foolishness”. They also lack complex nodes that require, for their maintenance, both qualified personnel and special equipment.

Deciphering the names of the pumps

Xx/xx xxxx-x (xxxx) -x-khhh-xxx-xxx

1 2 3 4 5 6 7 8 9

1. The diameter of the absacide pipe in inches (from 4 "to 20");

2. The diameter of the cluster pipe in inches (from 3 "to 16");

3. Marking the design of the prototype part (from 1 to 4 letters):

- gr- soil (I-th generation);

- W- highly upright (II generation);

- HG- gravel or soil (II generation);

- S (Semisubmersible) - semi -submarine;

- UW (Underwater) - submersible;

- K - Corundilated.

4. Designation of the 2-disk pump (Roman number). In the case of a single -disc pump - no.

5. The size and design of the rack (numbers and letters (letters may be absent if the design of the rack is standard on liquid lubricant)):

- numbers from 1 to 8 - stand -up rack;

- letters:

- S (Solid Lubricant) - solid lubricant;

- L is a lightweight option for small revolutions and dredgers;

- V - vertical performance;

6. Designation of modifications of execution:

- H- with high pressure (for pumps of the I-th generation);

- T - an enhanced option for especially difficult conditions.

7. The diameter of the working wheel in mm and the direction of rotation:

- diameter from 240 to 1150 mm;

- R or L - direction of rotation.

8. The width of the duct in the wheel with a worker in mm (from 25 to 300 mm).

9. The symbol of the enterprise - manufacturer.

Examples:

12/10hg-II- (5LS) -710R-180 -Pet-a gravel pump with a diameter of the absorption pipe/pressure of 12/10 inches, two-disc, at the rack No. 5 of a lightweight lubricant, with a working wheel Ø 710 mm, right rotation with a duct width 180 mm.

8/6WS-II- (4VS) -560R-75-Pet-a semi-submarine pump, the diameter of the absacide rods/pressure 8/6 inches, two-curricular, at the rack No. 4 on solid lubricant, with a working wheel Ø 560 mm, right rotation With a duct width 75 mm.

16/12GR-II- (7) -T-840R-160-PET-soil pump of the 1st generation for particularly difficult conditions, diameters of the absacide pipe/pressure 16/12 inches, two-curricular, on rack No. 7 on liquid lubricant, wheel Working Ø 840 mm, right rotation with a duct width 160 mm.

6/4W-II- (2) -400R-55-Pet-the pump is highly assigned with the diameters of the suction pipe/pressure of 6/4 inch, two-disc, at the rack No. 2 with liquid lubricant, with a working wheel of Ø 400 mm, right rotation with a width with a width duct 55 mm.

20/16hg-II- (7) -1100R-260-PET-gravel pump (soil of the II generation), with diameters of the absorption of the HIS/Netting 20/16 inches, two-curricular, at the rack No. 7 on liquid lubricant, with a working wheel of a worker Ø 1100 mm, right rotation with a duct width 260 mm.
