Abstract
The utility model discloses a single-stage single-suction horizontal centrifugal pump which comprises a motor and a pump body, wherein the motor and the pump body are provided with the same end cover; a water retaining ring which prevents water from entering into the motor caused by seal leakage is arranged at the joint of the motor and the pump body; a shaft of the motor extends into a cavity body of the pump body and provided with an impeller; glass ceramics are used to seal the sealing positions of the shaft and the pump body. According to the single-stage single-suction horizontal centrifugal pump, the motor and the pump body are provided with the same end cover, the shaft of the pump body is coaxial with a motor shaft. So that the motor shaft is lengthened, concentricity of the shafts is ensured, and the shafts are stable in operation, free from noise and vibration; the glass ceramics are used for sealing the sealing positions of the shaft and the pump body, so the single-stage single-suction horizontal centrifugal pump has relatively high resistance to acid and alkali, wear-resisting property and the like, and is good in hot and cold impact performance, simple in manufacturing method, low in cost, and beneficial for production application.
Description
Technical field
The utility model relates to a kind of centrifugal pump, relates in particular to a kind of single absorption horizontal centrifugal pump.
Background technique
Existing centrifugal pump arranges respectively between motor and the pump housing, be not easy to firm installation, and sealing is relatively poor between motor and the pump housing, namely produces leakage phenomenon after repeatedly using, and has brought inconvenience for the normal use of centrifugal pump.
The model utility content
The purpose of this utility model is to solve the problems of the prior art, and a kind of single absorption horizontal centrifugal pump is provided.
The technical solution of the utility model is: a kind of single absorption horizontal centrifugal pump, comprise motor and the pump housing, the same end cap of described motor and the pump housing, motor and pump housing connecting part are provided with to prevent from leaking because of sealing and make the water retaining ring of motor entering water, the shaft extension of described motor enters in the cavity of the described pump housing, at this axle impeller is installed, described axle and pump housing sealing place adopt sytull to carry out mechanical seal.
Be provided with the pressure plug on the described pump housing, just be provided with the air relief cock of air in the emptying pump beyond the Great Wall in this pressure.
Same end cap between the utility model motor and the pump housing, and the axle of the pump housing is coaxial with motor shaft, is the motor extension shaft, guaranteed axle with one heart, make that axle operates steadily, noise free and oscillation phenomenon; Adopt sytull to carry out mechanical seal at axle and pump housing sealing place, have higher antiacid alkali, wear-resisting property etc., and the thermal shock performance is good, manufacture method is simple, and cost is low, is convenient to production application.
