Abstract
The invention discloses a welded inner mixed type self-priming pump which is composed of a pump body, an impeller, a shaft, a belt wheel and the like. The pump body is composed of a water suction cavity, a centrifugal cavity, a water discharging cavity, a water storing cavity, a water return hole and the like. The water suction cavity is communicated with the centrifugal cavity through a circular hole. The impeller is arranged in the centrifugal cavity. A protective plate and a rubber cushion are arranged outside the impeller and seal the pump body. An arc-shaped steel plate with one sealed end and one unsealed end is arranged above the centrifugal cavity. When the welded inner mixed type self-priming pump is operated, water flows through the unsealed end (a high-pressure water channel) into the water discharging cavity. A water outlet is formed in the upper side of the water discharging cavity. The water storing cavity is arranged inside the water discharging cavity. A baffle is arranged between the water discharging cavity and the water storing cavity and the upper end of the baffle is not sealed. The water storing cavity and the centrifugal cavity are separated by the baffle as well. The water return hole is formed in the bottom of the baffle so that the water storing cavity and the centrifugal cavity can be communicated. The welded inner mixed type self-priming pump is simple in structure, a gas and liquid mixture is separated in the water discharging cavity, water flows back to the water storing cavity and enters the centrifugal cavity again through the water return hole, water flow blocking devices such as a jet device do not exist, working efficiency is high, and flow is large; a pump body welding structure is adopted, so that sealing effect is good and water supplying time is short; the welded inner mixed type self-priming pump is wide in the range of application and large in pump body intensity.
Description

Technical field
The present invention relates to a kind of solder type internal-mixing self-priming pump, relate to a kind of welded structure, install simple internal-mixing self-priming water pump.
Background technique
At present, the existing in the industry research widely of internal-mixing self-priming pump basis.Existing inventing type " self-priming pump " (notice of authorization CN 101358612 B) and model utility " internal-mixing jetted self-priming pump " (notice of authorization CN 201255119 Y) all are the internal-mixing self-priming pumps, are comparatively advanced at present self-priming pumps.But both structures are comparatively complicated, all are to utilize special spray nozzle device to produce high-speed jet, thereby form the condition of high vacuum degree in the gas-liquid mixed passage.Wherein the former inventing type self-priming pump structure of adopting gas-liquid mixed passage and normal intake tunnel to separate has improved manufacturing process and the cost requirement of the pump housing especially.Latter's model utility self-priming pump has increased reflux valve, has also just increased resistance to water-flow simultaneously, has reduced flow and the absorbent time of pump.Self-priming pump in the market generally adopts cast structure, easily bursting by freezing under low temperature environment, and the Environmental Conditions of pump is comparatively limited.
Summary of the invention
In order to overcome the deficiency of above internal-mixing self-priming pump, the invention provides a kind of solder type internal-mixing self-priming pump, not only simplified pump body structure, reduce manufacture cost, and can also augmented flow and absorbent time, the welded structure of the pump housing has increased the intensity of pump and has enlarged its using scope simultaneously.
The present invention is achieved through the following technical solutions:
A kind of solder type internal-mixing self-priming pump, include the pump housing, impeller, axle is formed, has water sucting cavity in the described pump housing, centrifugal chamber, drain chamber, water storage cavity, the backwater hole of offering by the dividing plate bottom between water storage cavity and the centrifugal chamber links, the rear side of the pump housing is welded with the intake pipe of a cuboid, the outside, upper end of intake pipe is welded with the water intake steel pipe, the inboard, lower end of intake pipe has the water sucting cavity that circular hole feeds the pump housing, water sucting cavity has circular hole to communicate with centrifugal chamber, be provided with the impeller that is installed on the axle in the centrifugal chamber, the impeller outside has backplate and rubber pad that the pump housing is sealed, top, centrifugal chamber is drain chamber, separated by curved plate between centrifugal chamber and the drain chamber, the top of drain chamber is provided with water outlet, and drain chamber is separated by dividing plate with the water storage cavity of inboard.
Curved plate one end of top, described centrifugal chamber is closed end, and the other end is open end, and open end and pump case form the high pressure water passage.
The described dividing plate upper end that separates drain chamber and water storage cavity is not sealed.
The dividing plate that described upper end is not sealed has also separated water storage cavity and centrifugal chamber simultaneously, and the dividing plate bottom has backwater hole, is communicated with water storage cavity and centrifugal chamber.
The described pump housing is welded by carbon steel.
Pump of the present invention injects a small amount of diversion before starting first, after this start inside and have water, and the water liquid level (has satisfied usage requirement) below suction chamber.During pump startup, after impeller is driven by motor or other power sources by axle and belt wheel, current and air can be mixed, pass through high-pressure channel, gas-liquid mixture separates in drain chamber, and gas is discharged by water outlet, and current are not enough because of pressure, overflow dividing plate and enter water storage cavity, get back to centrifugal chamber through backwater hole again.Can produce increasing degree of vacuum in centrifugal chamber simultaneously in this, extraneous current are entered into centrifugal chamber by water intake, cuboid pipeline, water sucting cavity, centrifugation accelerates enters into drain chamber again, arrive water storage cavity again, and so forth, water is more and more in the pump housing, and degree of vacuum is increasing, be full of the pump housing at last very soon, the water flow pressure of drain chamber is enough discharged by water outlet.
Each structure of the pump housing all is that high technology is welded, can bursting by freezing under the environment of cold, and the casting defects such as trachoma, pore in the cast member can not appear simultaneously, and enlarge the Environmental Conditions of pump and prolonged life-span of pump.It is carbon steel that the pump housing of the present invention adopts material, and it is light that the pump of making than cast iron has quality, advantages such as intensity height.
Advantage of the present invention is:
Structural design advantages of simple of the present invention, manufacture process requirement is lower; Current obstacle facilities such as no injection apparatus, high working efficiency, flow is big; Welded structure is with the obvious advantage, good sealing effect, and the last water time is short; Applied range, pump housing intensity is big.
