Axial Flow Pumps
1. Use:
The vertical high-temperature molten salt axial flow pump circulates the medium between the tubes in the tubular fixed-bed reactor, so that the reaction temperature is maintained within a certain temperature difference range, and the heat exchange medium acts as a carrier to remove the reaction heat.
2. Features:
2.1 Our company has an impeller computer design program with independent intellectual property rights. The mathematical model and simulation system for establishing the operating parameters of the molten salt axial flow pump are satisfied with the reactor matching requirements. This product uses six technical measures.
2.2 It adopts the integrated structure that can extract the whole impeller and shaft system from the pump casing, which is convenient for installation and maintenance. The optimum clearance is taken between the impeller and the pump body to maintain high pump efficiency. Strict requirements for dimensional tolerances and geometrical tolerances of the pump body and bearing frame are required to ensure accurate coaxiality.
2.3 Combined with the working condition characteristics of the vertical molten salt axial flow pump, the three-point axial pull rod with wedge can be used to adjust the fixing device at the sleeve bracket of the molten salt inner limit bearing seat. The pump shaft is accurately and firmly seated, ensuring smooth operation of the pump, minimizing pump vibration and greatly increasing pump life.
2.4 Adopting rigid shaft, the coaxiality of the shaft system is accurate, which makes the whole machine run smoothly, with low noise and long-term safe operation.
2.5. The limit bearing of the pump in the molten salt is made of special alloy. It is highly abrasion resistant and corrosion resistant.
2.6 The axial spacing of the rolling bearings is chosen reasonably. It is lubricated with high temperature grease. The lower bearing of the pump is cooled by water jacket or air cooled.
2.7 The pump casing and pump body are made of high quality steel that is compatible with the working conditions of the medium.

1. Pump flow: Q = (500-8000) m3/h
2. Pump head: H = (1.5-6) m
3. Pump revolutions: N = (420 -960) r / min
4. Pump operating temperature: t ≤ 500 °C
5. Motor power: P=(22-240) kw
