The R type hot water circulating pump is a single-stage single-suction and two-stage single-suction cantilever centrifugal pump. It is widely used in metallurgy, power stations, chemical industry and other sectors to deliver high-pressure hot water free of solid particles at a temperature below 250℃. When the hot water temperature reaches 250℃, the pump inlet pressure is 5 MPa. If the water temperature is no higher than 250℃, the inlet pressure shall not exceed 3 MPa.
Structural Features
The pump is mainly composed of pump casing, impeller, shaft, cooling chamber, casing support, bearing bracket, sealing components and wear rings. The inlet is horizontally axial and the outlet is vertically upward. The impeller passes static balance test and is fastened on the shaft together with the shaft sleeve via impeller nut. The pump shaft is supported on the bearing bracket by one pair of single-row angular contact ball bearings and one single-row radial ball bearing (or single-row radial cylindrical roller bearing).
The pump casing, cooling chamber and bearing bracket are connected by bolts. The pump is directly driven by a motor through a flexible coupling. Viewed from the drive end, the pump rotates clockwise.
It adopts floating ring seal or high-temperature and high-pressure resistant mechanical seal. The axial thrust is borne by single-row angular contact ball bearings; some models use impellers with back blades for axial force balance. Both the floating ring seal assembly and bearing bracket are equipped with cooling chambers, with the external cooling water flow rate ranging from 0.3 to 0.6 m³/h.
Main Applications
It is applicable to metallurgy, power stations, plastics, rubber, textile, chemical, wood processing, papermaking and other industries for conveying solid-free hot water below 250℃. It is also an ideal choice for hot water circulation in various heating systems.
Shaft Seal Types
Packing seal or mechanical seal. Heat exchangers can be equipped upon customer requirements.
Component Materials
According to different pressures, the materials of the main parts are: Class I: QT500-7; Class II: ZG230-450; Class III: ZG3Cr13
