First, an overview

1. Scope of application: for the company's production FJX now: diaphragm caustic soda, phosphoric acid, vacuum salt, lactic acid, calcium lactate, alumina, titanium dioxide, calcium chloride, ammonium chloride, sodium chloride, sugar, molten salt, papermaking, wastewater industry of evaporation, concentration, cooling, in order to improve the production capacity of the equipment, increase the mandatory cycle of the heat transfer coefficient of heat exchanger for.

2 Location: ground based (can be configured according to user needs elastic support) directly hanging on the evaporator.

3 pump form: vertical, bedroom.

4 transmission mode: direct drive transmission. Belt drive, hydraulic coupling, universal joint legend.

5 sealing structure: combined mechanical seal, packing seal.

8 over current component material

Pump body, an impeller, a rear cover, seal box, bushings, shaft protection sleeve, throttling ring, impeller cover flow of main materials by 1Ci18Ni9Ti, 316 and 316L, ZG20#, C4 steel, cd4mcu, Monel alloy, ha's C - 276, 904L, titanium alloy, heat resistant steel material for use in different working conditions.

Two, structural description

The factory production of evaporation circulating pump is a suspension type structure, the bedroom installed, some of the specifications of the digestive absorbed foreign advanced products a bit, so it has the following characteristics:

1 slow type: in line with the crystallization process requirements, stable operation.

2 excellent hydraulic performance, the same type III type II type efficiency than 5% efficiency, wide high efficiency range, anti cavitation performance.

The 3 seal structure requires the full consideration of user:

Combination type mechanical seal friction materials with high properties of wear resistant material, the use of long life, the combined seal easy maintenance

Packing seal: there are two kinds of single packing box and double packing box. Taking into account the evaporator, the company is specially designed for the user to design in evaporator material are not discharged circumstances can replace filling (the technology is the company from Goulds pumps company transfer to), regardless of the mechanical seal or packing seal can be used with expeller matched and arranged.

4 pump import and export direction change easy: the user will need to change the pump impeller anti loaded, at the same time, you can change the direction of steering pump inlet.

5 high reliability: a guide shaft cantilever end gas chamber, reduce shaft deflection.

6 water cooling type bearing seat: both ends of the bearing is provided with a cold water jacket. With thin oil lubrication, long life.

7FJXIII impeller has excellent anti cavitation performance, under the absolute pressure 0.05MPa can be normal operation.
