Description
Technical field
The present invention relates to a kind of technical field of pump, relate in particular to a kind of closed shaftless screw pump.
Background technique
At present in sewage treatment works; a large-scale volute pump that has is leaned in the lifting of activated sewage more; be also referred to as volute pump; it is this that a drawback of volute pump maximum is arranged is to be provided with bearing support under water; it is serious to bearing corrosion to contain mordant water or mud; sand, mud immerse the back wearing and tearing and strengthen, and bearing life is reduced, and often break down and shut down replacing.
In addition, have a volute pump need be provided with the accurately pump groove of cement components, this just needs to drop into a large amount of construction and expense.
Have, have a screw piece and cement pump groove that certain clearance is arranged, it is serious to promote seepage during running, influences lifting capacity, and efficient is low, and helical blade blocks because of foreign material and groove pump, influences the stable operation of process system.
Because this a volute pump is arranged is the water lift of open type, exist noise big, the problem that peculiar smell is big, winter, north temperature was lower, easily froze, and therefore need add large-scale outer cover protection, had so also strengthened the input of fund virtually.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, through a large amount of research and constantly exploration, provide have simple structure, reasonable in design, reliable operation, applicability be strong, low energy consumption, flow greatly, do not destroy a kind of closed shaftless screw pump of sludge activity.
Technological scheme of the present invention is as follows:
Closed shaftless screw pump, it comprises speed reducer, screw piece and the pump housing; Described speed reducer is located on the support, and the main shaft on the support links to each other with the pump housing by coupling, and pump housing bottom is provided with support, and the rotating screw sheet in the pump housing is fixedly connected on the pump barrel, also is provided with stainless steel filtering net in the pump housing.
The coaxality of the described main shaft and the pump housing.
The tilt angle of described screw piece and pump barrel is 38 ° or 45 °.
Described speed reducer is a parallel axes helical cut gear speed motor.
Described support is provided with four, and four are supported also coaxial symmetrically.
Advantage of the present invention and beneficial effect are as follows:
Closed shaftless screw pump of the present invention is on the basis of original volute pump, technical problem at its existence, by mechanism and design voluntarily that adopt not have the axle spiral, and a kind of novel mud, the sewage elevating mechanism developed according to requirement of engineering, low lift during its is fit to.The present invention relies on the rotation of the helical blade of pump housing internal fixation on pump barrel that low level water is risen to a high position.After Installation and Debugging, can keep long-time normal, stable, continuous operation, have high reliability.
The present invention has the novel structure compactness, and power drain is low, anhydrous step, and maintenance expenses is low, and setting angle can adopt big tilt angle, has the moderate and high characteristics of lifting efficient of lift.Pump housing member adopts the quality carbon steel material of high-quality stainless steel or advanced person's anticorrosion process application to make, and pump housing antiseptic property is good, long service life.
It is strong that the present invention also has simple structure, reasonable in design, reliable operation, applicability, and low energy consumption, flow are big, slow speed, do not destroy the characteristics of sludge activity.Be original up-to-date substitute products that a volute pump is arranged, and will promote the innovation of sewage treatment industry and association area new process.Product of the present invention is applicable to the pumping plant midway in city water processing, municipal waste water improvement, the municipal sewerage engineering, and the lifting of Sewage Plant water-in and water-out pumping plant and backflow also is widely used in farmland water drainage and irrigation, and its market application foreground is considerable.

Embodiment
Embodiment 1:
As depicted in figs. 1 and 2, Fig. 1 is a structural representation of the present invention; Fig. 2 is that A-A of the present invention is to view.
LSCP type closed shaftless screw pump of the present invention is to be driven by parallel axes helical speed reduction gear 8, be made up of support device, pump assembly, guard shield 4, supporting component, transmission device and damping support 2 etc., described support device comprises bearing support, main shaft, thrust-bearing etc.; Described transmission device is to adopt the special parallel bearing helical cut gear speed motor of producing of commercially available SEW.The described pump housing 1 comprises pump barrel, screw piece 3, rotary barrel etc.; Pump barrel is the major part of the pump housing, is rolled into a jar tube by corrosion resistant plate.Described thrust-bearing is meant and utilizes self-aligning thrust roller bearing that it plays the effect of bearing axial force.
Support of the present invention comprises base, bearing, axle, wheel, compositions such as bearing.Two groups of wheels are housed, axle and bearing in the bearing.The wheel support pump housing, bearing is connected with base hinge, base stone bolt and basic fixed.
Wherein, speed reducer 8 is located on the support 10, and the main shaft 5 in the support 10 links to each other with the pump housing 1 by coupling 9, and main shaft 5 and the pump housing 1 coaxality.The pump housing 1 bottom is provided with four also coaxial supports 2 symmetrically, and the rotating screw sheet 3 in the pump housing 1 is fixedly welded on the pump barrel, and the tilt angle of screw piece 3 and pump barrel is 38 °, also is provided with stainless steel filtering net in the pump housing 1.
The main shaft 5 in the support device and the coaxality of the pump housing 1, the degree of symmetry of four supports 2 need make it to keep coaxial with adjusting pad accurate adjustment when mounted, and buffer positioning structure is adopted in four supports 2, plays cushioning effect.Be provided with stainless steel filtering net in the pump housing 1, large-scale foreign material can be stopped, it can't be entered in the pump housing, guarantee the stable operation of closed shaftless screw pump.
This novel closed-type shaftless screw pump has a volute pump to compare to have removed bearing support under water with existing, increased the buffering supporting on the structure, there is not the axle screw piece there being a screw piece to become, save a vast sky axle and also alleviated the quality of the pump housing, next has removed the cement pump groove, has saved the cement components construction cost.Because novel closed-type does not have a screw piece and pump barrel adopts continuous welding; no leakage phenomenon; water lift efficient height; adopt 38 ° at big tilt angle or 45 ° all passable simultaneously; this angle has improved lift than 30 ° of tilt angle of original volute pump; because sewage or mud promote in the closed pump housing, noise free, free from extraneous odour need not large-scale outer cover protection again.
Working principle of the present invention is: the parallel axes helical speed reduction gear links to each other with the pump housing 1 by the main shaft 5 in the support, and the drive pump housing 1 rotation, the pump housing 1 rotates in four supports 2 that damping device arranged, rotating screw sheet 3 in the rotary course middle pump body 1 rises to high water level 11 places with the water or the mud of low water level 12 under the effect of rising reasoning, finish the lifting operation.
Embodiment 2:
The tilt angle of described in the present invention screw piece 3 and pump barrel is 45 °, and other is with embodiment 1.
