Description

Single-stage side draught clean waterpump

The utility model relates to a kind of water pump, adds the single-stage side draught clean waterpump of water in particular for airliner or boiler etc. there being the equipment of pressure requirement.

When aircraft need add water, (for example 0.2～0.3MP) can add water after it is opened to the pressure that needs at first to give the input of aircraft radiator valve certain.Method commonly used is mounting teeth roller box or a hydraulic oil motor before water pump, improves the pressure of its water outlet by the rotating speed that strengthens water pump, and then realizes opening radiator valve adds water to aircraft purpose.This water supply installation is owing to need mounting teeth roller box or hydraulic oil motor before water pump, not only complex structure, volume is big, cost is high, also easily the water source is polluted.

The single-stage side draught clean waterpump that the purpose of this utility model is to provide that volume is little, simple in structure in one, cost of production is low, can not polluted source.

Above-mentioned purpose of the present utility model is achieved through the following technical solutions: single-stage side draught clean waterpump of the present utility model comprises the pump housing that is connected and is formed by suction portion end cap, pump housing stage casing and outlet part end cap, and the outside of suction portion end cap and outlet part end cap has is convenient to the bearing support that cooperates with main shaft.Be characterized in being respectively arranged with water sucking mouth joint and water outlet joint being positioned on suction portion end cap above the bearing support and the outlet part end cap.Impeller is connected on the main shaft of suction portion end cap inboard, and the pump housing stage casing that is enclosed on the main shaft covers.Wherein, blade one side at impeller edge is cast with pressurizing ring.Also be cast with the helical water outlet in the pump housing stage casing.When main shaft and power source join, and when rotating under the drive of power source, impeller can rotate simultaneously.This moment, water can be inhaled in the impeller by the water sucking mouth joint as supplying water to the water sucking mouth, and water is under the impeller action of centrifugal force, and volume obtains compression, thereby the delivery pressure of water pump is strengthened.

Because blade one side at impeller of the present utility model edge is cast with pressurizing ring, does not need mounting teeth roller box or hydraulic oil motor, just can realize the enhancing of its delivery pressure, volume is little, and is simple in structure, and cost of production is low, can not pollute the water source.
