Description
Technical field
The utility model relates to a kind of single-stage double-suction centrifugal pump.
Background technique
S type single-stage double-suction centrifugal pump is the product of the unified design of water pump industry, is widely used in industries such as electric power, oil, chemical industry, smelting, papermaking.Its structure as shown in Figure 1, this single-stage double-suction centrifugal pump mainly is made up of the pump housing (10), pump cover (11), impeller (12), axle sleeve (9), packing seal (13), sleeve nut (14), bearing part (2) etc.Along with the further raising of user to nothing leakage and operational reliability requirement, the defective on this kind pump structure seems more outstanding, mainly contains: 1, bearing adopts grease lubrication, not the oily passage of oiling and blowdown.2, bearing is not provided with monitoring element, can not monitor in real time the safe operation of pump.3, gland sealed leaks environmental pollution by water, and power consumption is big, and filler needs often to change.
The model utility content
Technical problem to be solved in the utility model provides a kind of reliable, the single-stage double-suction centrifugal pump that packing seal and mechanical seal are general.
In order to solve the problems of the technologies described above, the single-stage double-suction centrifugal pump that the utility model provides, comprise the pump housing, pump cover, bearing part, axle sleeve and seal, under employing on the described bearing part is enterprising, go out to be provided with fuel filler neck and oil drain plug, thermometric or polarimetric element are housed at described bearing part.
Behind described axle sleeve back-up ring is housed, between described axle sleeve and the described back-up ring O RunddichtringO is housed, described seal is mechanical seal or packing seal, and gland is fixed on the described pump housing and the pump cover.
Adopt technique scheme single-stage double-suction centrifugal pump, kept original structure, only sealing and bearing part are improved, oil drain plug, thermometric or polarimetric element, fuel filler neck, machine sealed cover, back-up ring, O RunddichtringO, mechanical seal on original structure, have been increased, compared with prior art, have following advantage:
1, bearing has increased fuel filler neck and oil drain plug, can realize online oiling, has improved operational reliability and has saved the shutdown maintenance time.
2, bearing is provided with thermometric, polarimetric element, can realize the operation conditions of on-line monitoring water pump, has improved the Security of operation.
3, behind axle sleeve, increased back-up ring and O RunddichtringO, prevented that effectively medium from leaking vertically.
4, increased mechanical seal, realized that mechanical seal and gland sealed structure are general, be applicable to and carry corrosivity and toxic medium.
In sum, the utility model is a single-stage double-suction centrifugal pump a kind of simple in structure, reliable.
Description of drawings
Fig. 1 is single-stage double-suction centrifugal pump structure figure before improving;
Fig. 2 is the utility model structural drawing, and the left side is the mechanical seal signal, and the right side is the packing seal signal.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, oil drain plug 1, thermometric or polarimetric element 3, fuel filler neck 4, machine sealed cover 5, back-up ring 6, O RunddichtringO 7, mechanical seal 8 on original structure, have been increased.Oil drain plug 1 and fuel filler neck 4 are contained on the bearing part 2, go out under enterprising, and thermometric or polarimetric element 3 are contained on the bearing part 2.After back-up ring 6 was contained in axle sleeve 9, O RunddichtringO 7 was equipped with in the centre, and mechanical seal 8 is contained in former filler position, was fixed on the pump housing 10 and the pump cover 11 with machine sealed cover 5.
Adopt the structure of technique scheme, mechanical seal 8 can change packing seal 13 into, has realized that mechanical seal and gland sealed structure are general, is applicable to carry corrosivity and toxic medium.
The utility model is a kind of simple in structure, and reliable modified model single-stage double-suction centrifugal pump of new generation has very strong practical and popularizing value.
Personnel in the present technique field should be realized that, the foregoing description is not with this novel qualification of opposing, as long as in this novel connotation scope, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
