Abstract

The invention relates to a vertical single-stage torque flow pump which comprises a motor, a pump body, a rotating shaft, a pump cover and an impeller. A supporting base is arranged at the lower portion of the pump body. A channel partition plate is arranged above the supporting base. The pump cover is arranged in the pump body and located above the channel partition plate so that a press-out chamber can be formed. The motor is longitudinally arranged at the upper end of the pump body. The rotating shaft is longitudinally arranged in the pump body. The motor is connected with the rotating shaft. One end of the rotating shaft penetrates through the pump cover and enters the press-out chamber. The impeller is fixedly connected with the end, located in the press-out chamber, of the rotating shaft. The impeller comprises a rotating center connected with the rotating shaft and a plurality of blades evenly distributed around the rotating center. Gaps are formed between the lower side edges of the blades and the upper side face of the channel partition plate. No sealing element needs to be installed between the impeller and the pump body, and the problem that an existing vertical single-stage pump is low in efficiency when a sealing element is abraded does not exist; on the premise of not increasing the overall size of the pump body, compared with the existing vertical single-stage pump, the vertical single-stage torque flow pump has the advantages that the stroke is larger and can not be decreased even when flow is increased.

Description

Vertical single stage torque flow pump
Technical field
The present invention relates to vertical single stage pump field, is especially a kind of vertical single stage torque flow pump.
Background technique
Existing vertical single stage pump adopts centrifugal pump structure, there is running clearance, the matching gap namely between the pump housing and impeller in pump between high and low pressure chamber, and the above-mentioned gap of the working efficiency team in order to ensure centrifugal pump adopts seal ring to realize sealing, and it exists following shortcoming:
1., in order to obtain larger lift, existing vertical single stage pump can only rely on impeller diameter to become large, causes pump volume to increase;
2., after long-play, pump seal ring portion position meeting Fast Wearing, causes pump performance to decline;
3. most of centrifugal pump, increase with flow, lift declines continuously and healthily, can not meet the requirement of fire water pump standard.
Summary of the invention
The object of the invention is to solve the problem, and provides a kind of vertical single stage torque flow pump, is specifically realized by following technological scheme:
A kind of vertical single stage torque flow pump, comprise motor, the pump housing, rotating shaft, pump cover and impeller, the bottom of the pump housing is supporting base, the top of supporting base is runner dividing plate, described pump cover to be arranged in the described pump housing and to be positioned at the top of described runner dividing plate, thus forms delivery chamber between pump cover and runner dividing plate; Described motor is longitudinally arranged at the upper end of the pump housing, described rotating shaft is longitudinally arranged in the pump housing, the output shaft of motor is connected with described rotating shaft, and one end of rotating shaft enters described delivery chamber through described pump cover, and the end winding support that described impeller and rotating shaft are positioned at delivery chamber is connected; Described impeller comprises the center of rotation be connected with rotating shaft and the some blades be dispersed evenly to around described center of rotation; There is 3-5mm gap between the lower edge of described blade and the upper side of described runner dividing plate, thus formed without phyllocyst in the bottom of delivery chamber; Be provided with the hole relative with described center of rotation in the middle part of described runner dividing plate, and this duct is by liquid inlet pipe and pump housing ft connection; The outer installment of the described pump housing has drain pipe, and this drain pipe laterally penetrates the pump housing and is communicated with described delivery chamber.
Described vertical single stage torque flow pump, it designs further and is, the upper side of described runner dividing plate is provided with the annular groove be positioned at around described hole, and this annular groove is relative with described blade, thus forms circular flow region in the bottom without phyllocyst.
Described vertical single stage torque flow pump, it designs further and is, the maximum depth of described annular groove is 3mm, and its width is equal with described length of blade.
Described vertical single stage torque flow pump, it designs further and is, the middle part of described pump cover is upwards swelled, and has toroidal cavity between this bump pad and rotating shaft, and this toroidal cavity is built-in with the sub-propeller be fixedly connected with described rotating shaft.
When the impeller of vertical single stage torque flow pump provided by the invention rotates in delivery chamber, the fluid entering delivery chamber is divided into from the through stream at drain pipe row place and at the circular flow accelerated without phyllocyst Inner eycle, without the need to arranging Sealing between impeller and the pump housing, there is not the problem of the inefficiency that existing vertical single stage pump causes due to sealing part abrasion, and under the prerequisite not increasing pump housing overall dimensions, compared with existing vertical single stage pump, there is larger lift, also can not decline even if flow increases lift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is further described.
As shown in Figure 1, this vertical single stage torque flow pump comprises motor 1, the pump housing 2, rotating shaft 3, pump cover 4 and impeller 5, the bottom of the pump housing is supporting base 21, the top of supporting base is runner dividing plate 22, pump cover 4 to be arranged in the pump housing and to be positioned at the top of runner dividing plate, thus forms delivery chamber 5 between pump cover and runner dividing plate; Motor is longitudinally arranged at the upper end of the pump housing, and rotating shaft 3 is longitudinally arranged in the pump housing, and the output shaft of motor is connected with rotating shaft, and one end of rotating shaft enters delivery chamber through pump cover, and the end winding support that impeller 5 and rotating shaft are positioned at delivery chamber is connected; Impeller comprises the center of rotation be connected with rotating shaft and the some blades be dispersed evenly to around center of rotation; There is 3-5mm gap between the lower edge of blade and the upper side of runner dividing plate, thus formed without phyllocyst 51 in the bottom of delivery chamber; Be provided with the hole 221 relative with center of rotation in the middle part of runner dividing plate 22, and this duct is by liquid inlet pipe 6 and pump housing ft connection; The outer installment of the pump housing has drain pipe 7, and this drain pipe laterally penetrates the pump housing and is communicated with delivery chamber.
The upper side of runner dividing plate 22 is provided with the annular groove 222 be positioned at around hole, and this annular groove is relative with blade, thus forms circular flow region in the bottom without phyllocyst.The maximum depth of annular groove is 3mm, and its width is equal with length of blade.
