Description
Technical field
The utility model belongs to centrifugal pump, is a kind of grease middle open type slag stock pump.
Background technique
The slag stock pump is widely used in industries such as iron and steel, mine, smelting, generating, coal washing, chemical industry and carries the solid-liquid fluid-mixing, the lubricating system of the bearing support of slag stock pump has two kinds of oil lubrication and grease lubrication: the greasy property of oil lubrication is good but easily leak, grease lubrication does not have leakage problem but the bearing support heating is serious, and this does not also have good solution at present to contradiction.
Summary of the invention
The purpose of this utility model provides a kind of intercalated water sleeve grease middle open type slag stock pump, it adopts the grease lubrication mode, there is not leakage problem, the direct cooling bearing of water of while intercalated water sleeve, can guarantee bearing temperature in permission range, solved well oil lubrication leakage and grease lubrication weak effect this to contradiction.
Solution of the present utility model is as follows: the utility model is made up of sheath, front pump cover, impeller, sub-propeller, apron plate, rear pump cover, back backplate, decompression lid, black box, carriage, lower bearing body, adjusting bolt, end cap, sealing cover, axle, bearing, oil baffle disc, upper bearing (metal) body, stripping ring, axle sleeve.Bearing support is connected fastening forming by the lower bearing body with upper bearing (metal) body and function bolt; intercalated water sleeve is offered down in lower bearing body and bearing contacting point; intercalated water sleeve is offered in upper bearing (metal) body and bearing contacting point; the last intercalated water sleeve of upper bearing (metal) body just in time aligns when assembling with the following intercalated water sleeve of lower bearing body and is communicated with; in order to prevent that the water in the intercalated water sleeve from leaking; the mating face is adopted the two-stage sealing configuration and is placed twin-stage flexible barrier pad; intercalated water sleeve was offered a circle spill mouth under place, lower bearing body mating face centered on; the material of anti-leakage pad is a rubber plate; the soft sheet of moulding; the scraps of paper; O type circle etc.; under the protection of this two-stage sealing configuration; even first order sealing is just in case seepage occurs; second level sealing can be blocked the seepage of first order sealing, has reached the requirement of zero leakage.In order to prevent the dislocation of metal (upper body, locating stud has also been squeezed on the mating face, the lower bearing body has stretched out the adjustment ear of a with holes or breach downwards, regulating bolt is fixed in the lower bearing body on the carriage by this adjustment ear, regulate and settle two nuts to clamp the adjustment ear from both sides on the bolt, can firmly fix on the one hand bearing support can't axial float, can regulate the gap that moves axially and regulate impeller and front and back backplate of bearing support on the other hand easily, the assembling and the maintenance of pump brought great convenience.The upper bearing (metal) body is offered four (two groups) screws and is communicated with intercalated water sleeve and jointing, is connected with conduit pipe by joint again.Decompression covers offers a moisturizing hole (owing to will turn in the hole, the hole can only cast out), and moisturizing hole one end is in communication with the outside and affixed joint, and the other end leads to the endoporus Intermediate shaft sleeve and the sub-propeller junction of decompression lid.
The utility model adopts grease lubrication, does not have the oil leakage problem, and bearing has obtained the abundant cooling of the cooling water in the intercalated water sleeve simultaneously, and the temperature of bearing is limited in the permission range, can prolong the working life of bearing.The utility model can be regulated moving axially of bearing support by the adjustment ear on the lower bearing body easily by regulating bolt; assembling and maintenance have been simplified; decompression covers and offers the moisturizing hole; can wash axle sleeve and sub-propeller with clear water by it; reduce the wearing and tearing of particulate matter, protected axle sleeve and mechanical sealing element effectively axle sleeve and mechanical sealing element.Advantage of the present utility model is: 1. do not have the oil leakage problem; 2. bearing has obtained good cooling, the bearing long service life; 3. it is easy to adjust and fastening firm to move axially; 4. axle sleeve and mechanical sealing element have obtained good flushing protection, but significant prolongation its working life.
