I. Overview

    1, the scope of application: The company produces FJX forced circulation pump is now used: diaphragm caustic soda, phosphoric acid, vacuum salt, calcium lactate, alumina, calcium chloride, ammonium chloride, sodium chlorate, sugar, , Paper, waste water and other industries evaporation, concentration, cooling, in order to improve equipment production capacity, increase the heat transfer coefficient of the heat exchanger for forced circulation.

    2, forced circulation pump is divided into: vertical, horizontal, direct drive, belt drive, hydraulic coupling, universal joint drive.

    3, sealed structure: modular mechanical seal, packing seal.

    4, over-flow parts Material:

The main materials such as 1Ci13Ni9Ti, 316,316L, ZG20 #, C4 steel, CD4MCu, Monel alloy, and so on are the main materials of the flow parts such as pump body, impeller, rear cover, shaft sealing box, sleeve, shaft protective cover, Hastelloy C-276,904L, titanium alloy, heat-resistant wear-resistant steel and other materials for different conditions of choice.

Second, FJX type forced circulation pump structure description

The factory production of FJX forced circulation pump for the cantilevered structure, horizontal installation, some specifications digestion and absorption of foreign advanced product features, which has the following characteristics:

    1, slow type: meet the crystallization process requirements, running smoothly.

    2, excellent hydraulic performance, the same type Ⅲ efficiency than Ⅱ type efficiency increased by 5%, efficient area wide, good anti-cavitation performance.

    3, shaft seal structure to fully consider the user requirements:

Combined mechanical seal: friction to pay the material using high-performance wear-resistant materials, long life, the use of modular seal easy maintenance.

Packing seal: a single packing box and double packing box two kinds, taking into account the situation of the evaporator, the company specially designed for the user in the evaporator material does not remove the case can replace the filler, whether mechanical seal or packing seal with the impeller With the set.

    4, the pump to change the direction of easy to change: the user only need to install the impeller, while changing the pump steering, pump import and export direction can be changed.

    5, high reliability: shaft cantilever set diversion chamber, reduce the shaft deflection.

    6, water-cooled bearing: both ends of the bearing at the water jacket, with thin oil lubrication, long service life.

    7, FJX Ⅲ impeller has excellent anti-cavitation performance, the absolute pressure of 0.05MPa can also be normal operation.

Third, the performance range

    Flow: 300-23000m3 / h Head: 2-7M

    Working pressure: ≤ 0.6MPa

    Working temperature: ≤480 ℃

Fourth, the model meaning

    For example: FJX-450

    FJX: forced circulation pump, axial flow pump, evaporative circulation pump

    450: impeller diameter mm
