Description
Technical field
This utility model belongs to fluid machinery technical field, is related to a kind of water pump, particularly to a kind of centrifugal multistage pump multiple centrifugal pump.
Background technology
Centrifugal pump is to make liquid centrifugal motion occur come work using impeller rotation, and centrifugal pump operationally, relies on
The impeller of high-speed rotation, liquid obtains energy to improve pressure in the presence of centrifugal inertial force, centrifugal pump before work, pump
The necessary hydraulically full medium of internal and inlet line, prevents cavitation phenomenons from occurring, when impeller quick rotation, blade promotes medium
Rotate quickly, the medium being rotating flies out from impeller under the influence of centrifugal force, after the liquid in pump is spilled over, the center of impeller
Part forms vacuum area, simultaneously constantly sucks liquid, simultaneously and constantly gives to suck the certain energy of liquid by liquid
Exclusion.The centrifugal pump of existing structure is generally only provided with water inlet and outlet, the centrifugal pump pump housing before activation in the market
Interior must be full of water, if because leakage water level is likely to occur deficiency in water pump pump housing after long-time deactivation, must beat like that
Drive the mouth of a river into and again pour water toward in the pump housing and bother very much.
Content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided a kind of practicality is more preferable
Centrifugal multistage pump multiple centrifugal pump.
The purpose of this utility model can be realized by following technical proposal: a kind of centrifugal multistage pump multiple centrifugal pump, including motor and pump
Body, is fixedly connected with by hex nut between described motor and the pump housing, and described motor is installed on steel base together with the pump housing
On, the end of the described pump housing axially offers water inlet, the top radial direction of the described pump housing offer outlet it is characterised in that
In the described pump housing, water inlet is provided with thrust bearing, described thrust bearing is axially provided with power transmission shaft, described
Power transmission shaft on be provided with some groups of impeller assemblies, be connected and shaft coupling by shaft coupling between described power transmission shaft and motor
On be provided with mechanical seal, the side wall of the described pump housing offers spilled water hole and spilled water hole is sealed by plug screw.
The principle of this centrifugal multistage pump multiple centrifugal pump is: by arranging thrust bearing in water inlet, can effectively prevent impeller assembly
The impact to performance of centrifugal pump stability for the axial thrust producing in work, increased the stability of centrifugal pump, and in pump housing side
Offer spilled water hole on wall, if in centrifugal pump does not use for a long time, plug screw can be opened the liquid in the pump housing is released, prevent
Only the metal parts in the pump housing gets rusty, and centrifugal pump does not have hydraulically full before activation and in the pump housing, can open plug screw directly past
Pour water in the pump housing, pour water from outlet with respect to tradition, the practicality of this centrifugal pump is more preferable.
In a kind of above-mentioned centrifugal multistage pump multiple centrifugal pump, described water inlet is provided with check-valves.
In a kind of above-mentioned centrifugal multistage pump multiple centrifugal pump, described impeller assembly number is 6.
In a kind of above-mentioned centrifugal multistage pump multiple centrifugal pump, described motor is to be provided with wiring on threephase asynchronous and motor
Box.
Compared with prior art, this centrifugal multistage pump multiple centrifugal pump has performance and more stablizes and the more preferable advantage of practicality.
