Description
Technical field
The present invention relates to Under Water Pumps technical field, relate in particular to a kind of flexible support Under Water Pumps.
Background technique
Along with social development and the raising of process engineering, more and more higher to the usage requirement of Under Water Pumps.Existing Under Water Pumps mainly comprises motor, upper end thrust bearing part, lower end sliding bearing supporting part, pump housing parts and rotatable parts, what existing Under Water Pumps leaned on is radial force and the axial force that the thrust bearing of upper end and the sliding bearing of lower end bear rotatable parts, the thrust bearing of upper end bears whole axial forces of rotatable parts, the sliding bearing of a lower end bearing radial force.
Because the axle of Under Water Pumps is longer, at running axis, can produce larger amount of deflection, pump is produced to vibration, the wearing and tearing of the sliding bearing of simultaneously accelerating lower end in operation process, the larger vibration of wearing and tearing is larger, when serious, even damages pump and motor, has greatly reduced the working life of pump.In manufacturing the process of pump, the uneven meeting generation of quality radial force due to rotational parts, simultaneously on the needs of design, pump because waterpower imbalance also can produce radial force, if axle is longer, can produce larger amount of deflection at operation process axis in running, the larger vibration of amount of deflection is larger, the wearing and tearing of guide bearing are below larger, and when the sliding bearing abrasion of lower end is more serious, pump just cannot normally move.If also continue operation, will cause equipment badly damaged.
Summary of the invention
Above-mentioned defect and problem for prior art, the object of this invention is to provide a kind of flexible support Under Water Pumps with flexible support part, solve existing Under Water Pumps and compared with long, produce larger amount of deflection because of axle, pump is produced to vibration, the wearing and tearing of the sliding bearing of simultaneously accelerating lower end in operation process, and then affect the problem in the working life of pump.
In order to achieve the above object, the invention provides following technological scheme:
A kind of flexible support Under Water Pumps, comprise motor, upper end thrust bearing part, lower end sliding bearing supporting part, pump housing parts and rotatable parts, described motor, upper end thrust bearing part, lower end sliding bearing supporting part is connected in turn with rotatable parts, and be arranged on pump housing components interior, between described upper end thrust bearing part and lower end sliding bearing supporting part, by major axis, connect, wherein, also comprise flexible support part, described flexible support part comprises soft supporting base, flexible support ring and gland, described soft supporting base is the cylindrical shell that upper and lower end face arranges opening, the outer side wall of described flexible support ring is arranged on the madial wall of soft supporting base, on described gland, circular hole is set, gland is arranged on the upper-end surface of soft supporting base, the flexible support part in the middle of forming with through hole, described flexible support part is set on described major axis by through hole, and be fixedly installed on pump housing parts by soft supporting base.
Further, described flexible support ring, soft supporting base and gland coaxially arrange.
Particularly, the internal diameter of described flexible support ring is identical with the external diameter of major axis.
Particularly, the radius that adds and be not less than the lower end surface opening of soft supporting base of the radius of the upper-end surface opening of described soft supporting base and flexible support ring thickness; Preferably, the radius that adds and equal the lower end surface opening of soft supporting base of the radius of the upper-end surface opening of described soft supporting base and flexible support ring thickness.
The diameter of the circular hole arranging on described gland particularly, is identical with the internal diameter of flexible support ring.
Particularly, described gland is arranged on the upper-end surface of soft supporting base by connecting bolt.
Further technological scheme is, the sidewall of the soft supporting base of described flexible support part is hollow structure, on the outer side wall of soft supporting base, warter connection is set, connection cooling water is in operation, take away the heat producing in running, extend service cycle, greatly improved the working life of pump.
On the major axis that the present invention is connected with lower end sliding bearing supporting part at upper end thrust bearing part, added flexible support part; in the process of rotating at rotatable parts; effect due to flexible support ring; the amount of deflection having produced while having reduced rotatable parts running; reduced the vibration to pump; the Fast Wearing of the sliding bearing that prevents lower end in operation process, protection pump and motor.This flexible support part plays a part to bear rotatable parts part radial force, reduces the amount of deflection of axle, the stability of the wearing and tearing of the easily damaged parts that slows down, increase pump.
The amount of deflection of the axle of flexible support Under Water Pumps of the present invention is very little, vibrates littlely, and easily damaged parts wearing and tearing are slow, service cycle compared with long, maintenance frequency is few, operating cost is lower, long service life.
Flexible support Under Water Pumps of the present invention is generally suitable for the industries such as metallurgy, oil, chemical industry, power plant, agricultural production, national defence scientific research, environmental protection.
