Purpose: Pumps of the Central History type and pumping units based on their type of ACN are designed to pump water with a temperature of up to 100 0 C B. water supply systems of industrial and communal facilities, reclamation.
Construction: Central center pumps- centrifugal, horizontal, spiral with a horizontal case connector, with translated channels, two- or four-stage, with single-sided entrance workers symmetrically located On the shaft. The supports of the pump rotor are supporters with plastic lubrication. Shaft seals - mechanical with a stuffing box,
Materials:
- houses, lids and working wheels - castings of gray cast iron;
- Details of slit seals - unprotected corrosion -resistant alloys;
- Val - varietal rental from structural alloy steel 40x.
completeness:
- A collected pump with auxiliary pipelines within the pump;
- response flanges on nozzles;
- drive electric motor;
- Connecting coupling like MUVP or MUP with a fence;
- General or separate foundation frames (depending on the size of the pump);
- Parts of fastening the pump, engine and fencing of the coupling;
- SIP.
The apparatus considered for pumping fluids, carried out using the pressure created by the centrifugal force of the rotating working wheel. Devices are used, as a rule, in industrial enterprises and in utilities. The advantages of these attitudes include the ability to pump up to 1000 m 3 /hour. You can also add the opportunity:
- work in non-stop mode for a long time;
- Ignore abrasive particles up to 0.21 mm.
For normal operation of the unit, it is required A powerful 630 kW electric motor, developing 1,500 rpm.
