Abstract
The invention discloses a side suction pump. According to the technical scheme of the side suction pump, the side suction pump comprises a pump body and a motor. A water inlet is formed in one side of the pump body. A water outlet is formed in the top of the pump body. A working impeller is arranged in a cavity of the pump body. The working impeller is mounted on a motor shaft. A pump cover is arranged on the inner side of the working impeller. The motor shaft penetrates the pump cover. An air suction channel is formed in the pump cover. A self-priming impeller is arranged on the inner side of the pump cover. The self-priming impeller is mounted on the motor shaft in a sleeving manner. A connecting frame is arranged on the inner side of the self-priming impeller. A cavity is formed in the connecting frame. The cavity communicates with an exhaust pipe. A C-shaped centripetal flow channel is arranged in the face where the connecting frame adjoins the self-priming impeller. A side suction structure and a strong self-priming device are adopted by the side suction pump and replace a bulky fluid storage device and a bulky gas-liquid separation device adopted by existing self-priming pumps or a water diversion device such as a vacuum pump adopted by existing self-priming pumps, and accordingly the side suction pump has a quite compact structure, raw materials are saved, and the manufacturing cost is low.
Description
Technical field:
The present invention relates to water pump, particularly pump is inhaled in a kind of side.
Background technology:
The present use of vacuum primingpump is very general, it is owing to need not add diversion before starting every time, by the effect of pump itself, namely can complete from inhaling, the pump housing is made to drop into normal operation, so vacuum primingpump widespread use in the industrial production, especially in occasions such as fire-fighting, chemical industry, boats and ships, field irrigation, pipe pressurizing, cultivation and plumbing. But still there is shortcoming in the process that on market, existing vacuum primingpump uses in reality. As: bigger installation space need to be taken when complex structure, the big installation of preposition self-priming apparatus volume, waste material, the drawback that cost is high; Self-priming time length, suction lift are low; Efficiency is low, flow is little.
Summary of the invention:
It is an object of the invention to design that a kind of structure is simple, strong from suction ability, self-priming time is short, compact construction, utilizes side direction air-breathing to realize self-suction function, it may also be useful to pump is inhaled in effective side.
The technical scheme of the present invention is, pump is inhaled in a kind of side, it comprises the pump housing, motor, it is characterized in that: pump housing side is provided with water-in, pump housing top is provided with water outlet, it is provided with running wheel in the cavity of the pump housing, running wheel is arranged on motor shaft, the inner side of running wheel is provided with pump cover, motor shaft is through pump cover, pump cover is provided with air intake passage, it is provided with inside pump cover and takes turns from phyllidium, it is sleeved on motor shaft from phyllidium wheel, it is being provided with link span from phyllidium wheel inner side, link span is provided with cavity, cavity and vapor pipe UNICOM, with taking turns from phyllidium, adjacent one side is provided with the centripetal runner of " C " shape at link span. the top of described vapor pipe is provided with throttling orifice plate. the side that described impeller is adjacent with water-in is provided with sealing-ring. the part that pump cover is adjacent with the cavity of the pump housing is provided with O shape sealing-ring. mechanical seal is adopted between link span and motor shaft.
The present invention adopts side-suction type structure and strong self-suction device design, instead of the diversion device such as bulky device for storing liquid and gas-liquid separation device that existing vacuum primingpump adopts or the vacuum pump that existing vacuum primingpump adopts, the structure making the present invention is closely, and saving starting material, manufacturing cost is comparatively cheap.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention,
Fig. 2 is the structural representation of pump cover of the present invention,
Fig. 3 is the structural representation of link span of the present invention,
Fig. 4 is the structural representation from phyllidium wheel of the present invention.
Embodiment:
Embodiment 1,
The structure of the present invention is, pump is inhaled in a kind of side, it comprises the pump housing 1, motor 7, pump housing side is provided with water-in 12, pump housing top is provided with water outlet 2, running wheel 3 it is provided with in the cavity of the pump housing, running wheel is arranged on motor shaft 6, the inner side of running wheel is provided with pump cover 11, motor shaft is through pump cover, pump cover is provided with air intake passage 4, it is provided with inside pump cover and takes turns 10 from phyllidium, it is sleeved on motor shaft from phyllidium wheel, it is being provided with link span 9 from phyllidium wheel inner side, link span is provided with cavity 8, cavity and vapor pipe 5 UNICOM, link span takes turns adjacent one side with from phyllidium, link span is provided with the centripetal runner 14 of " C " shape, the top of the vapor pipe described in the present embodiment can be provided with throttling orifice plate 13.
Embodiment 2, pump is inhaled in a kind of side, it comprises the pump housing, motor, pump housing side is provided with water-in, pump housing top is provided with water outlet, it is provided with running wheel in the cavity of the pump housing, running wheel is arranged on motor shaft, the inner side of running wheel is provided with pump cover, motor shaft is through pump cover, pump cover is provided with air intake passage, it is provided with inside pump cover and takes turns from phyllidium, it is sleeved on motor shaft from phyllidium wheel, it is being provided with link span from phyllidium wheel inner side, link span is provided with cavity, cavity and vapor pipe UNICOM, link span takes turns adjacent one side with from phyllidium, link span is provided with the centripetal runner of " C " shape, the side that impeller described in the present embodiment is adjacent with water-in is provided with sealing-ring, the part that pump cover described in the present embodiment is adjacent with the cavity of the pump housing is provided with O shape sealing-ring, mechanical seal is adopted between link span and motor shaft described in the present embodiment.
What employing of the present invention and running wheel were installed on same axis absorbs water from the pump housing from phyllidium wheel, gas in upstream line simultaneously, pressure under the effect of phyllidium wheel in rear side carries out gas-liquid mixed, during the centripetal runner of C type of mixed liquid on link span transfers out, and complete gas-liquid separation in the discharge cavity of link span, gas after separation is discharged from vapor pipe, liquid return participates in gas-liquid mixed again to the centripetal runner of C type, make suction line is formed vacuum simultaneously, the discharge of gas to complete in suction line so repeatedly, realize self-suction function.
