Abstract
The utility model discloses a screw submersible pump, which includes a pump head, a pump cylinder and a motor, wherein an output shaft of the motor passes through a bearing pedestal of the motor and is connected with a screw core through a coupling, a screw sleeve spirally matched with the screw core is fixed on the lower end surface of the pump head through a first bolt, a connecting piece is provided with a cylindrical main body, a connecting flange is arranged at the lower end of the cylindrical main body and is fixed on the bearing pedestal of the motor through a second bolt, the upper end part and the lower end part of the pump cylinder are respectively sleeved at the lower end of the pump head and the upper end of the cylindrical main body, and a seal ring is arranged between the pump head and the inner wall of the pump cylinder, as well as between the cylindrical main body and the inner wall of the pump cylinder. In the utility model, the connecting piece is arranged between the motor and the pump cylinder, and the bolt for connecting the connecting piece with the bearing pedestal of the motor can be loosened to enable the motor to be taken down, so that the screw core and the screw sleeve can be replaced very conveniently.
Description
Technical field
The utility model relates to submersible pump, particularly relates to the screw rod submersible pump.
Background technique
Screw rod Submerged Motor Pumps (abbreviation screw pump) is compared with general Submerged Motor Pumps (centrifugal pump, axial flow, mixed-flow), has following advantage:
(1), lift do not have the restriction of little stop, as long as within the most high-lift scope that allows, all can work smoothly.The lift of screw rod Submerged Motor Pumps is regulated automatically with pipe resistance, and pump group and power consumpiton and lift are approximated to direct ratio.
(2), the lift height, the efficient height, the pump group efficient in the 30-50 rice range of lift is than the high 50-100% of general Submerged Motor Pumps.Therefore use this pump to save the valuable energy, reduce the power supply expense for you.
Owing to the screw rod Submerged Motor Pumps has above-mentioned advantage, thus of many uses, be applicable to remote flat defeated the irrigation and sprinkling; The efficient aeration pump of aquaculture; The building pump that the town and country tap water boosting is used; Foundation ditch, mine drainage and food, chemical industry are carried slurry pump etc.
But, in the existing screw pump, screw rod is a package assembly all linked with one another from bottom to top, because screw pump in the course of the work, is transferred and contains a certain amount of impurity in the liquid, the long-term use, can cause the loss of screw rod, when screw rod damages replacing, need to put in order screw pump and dismantle fully just and can change, thereby caused great inconvenience to safeguarding with maintenance, not only time-consuming but also require great effort.
The model utility content
Technical problem to be solved in the utility model is to solve the problem that screw pump is changed the screw rod inconvenience.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted provides a kind of screw rod submersible pump, comprise pump head, pump barrel and motor, the output shaft of motor passes the motor shaft bearing and is connected with the screw rod core by shaft joint, the screw rod cover that cooperates with screw rod core spiral is bolted on the lower end surface of pump head by first, link has a cylindrical body, the lower end of this cylindrical body is provided with adpting flange, adpting flange is bolted on the motor shaft bearing by second, on the pump barrel, the underpart is sleeved on the lower end of pump head and the upper end of cylindrical body respectively, and is respectively equipped with seal ring between the inwall of pump head and cylindrical body and pump barrel.
The utility model is provided with link between motor and pump barrel, unclamp the bolt that is connected between link and the motor shaft bearing and motor can be taken off, and greatly facilitates the replacing of screw rod core and screw rod cover.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model comprises the pump head 9 that is used to carry liquid, pump barrel 11 and motor 1, the output shaft 2 of motor 1 passes motor shaft bearing 13 and is connected with screw rod core 6 by shaft joint 4, the screw rod that cooperates with screw rod core 6 spirals cover 8 is fixed on the lower end surface of pump head 9 by first bolt 10, link 12 has a cylindrical body, the lower end of this cylindrical body is provided with adpting flange, adpting flange is fixed on the motor shaft bearing 13 by second bolt 3, on the pump barrel 11, the underpart is sleeved on the lower end of pump head 9 and the upper end of cylindrical body respectively, and is respectively equipped with seal ring 7 between the inwall of pump head 9 and cylindrical body and pump barrel, 5.
The utility model is changed screw rod core 6 and screw rod and is overlapped 8 very convenient, detailed process is as follows: at first unclamp second bolt 3, link 12 and motor shaft bearing 13 are taken apart, then this link 12 and above part are upwards mentioned, shaft joint 4 and motor output shaft 2 are separated, thereby motor 1 is unloaded (if motor output shaft 2 and shaft joint 4 screw-thread fit, then need at first with motor 1 counter-rotating, unclamp being connected of motor 1 and shaft joint 4, if adopt keyway to cooperate between the two, then can directly take off), afterwards the pump housing partly is inverted, take off link 12 and unclamp first bolt 10 between screw rod cover 8 and the pump head 9, finish screw rod core 6 and screw rod and overlap 8 replacing.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technological scheme, all fall within the protection domain of the present utility model.
