Description
Technical field
The utility model relates to pumping equipment field, especially a kind of circulating water pump.
Background technique
In woolen dyed treatment industry, to dyeing waste-water cycling and reutilization process, adopt water pump that water is evacuated to appointed area.But owing to there is the more wool etc. be scattered in waste water, easily block between impeller and the pump housing and between the pump housing and transmission shaft in the process of drawing water, cause cannot running of equipment, rate of fault is high, affects manufacturing efficiency.
Model utility content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple, and usability is superior, the circulating water pump of situation of effectively can avoid occurring transmission shaft blocking, hanging.
In order to achieve the above object, circulating water pump designed by the utility model, it comprises on the pump housing, pedestal, pedestal and is provided with motor, motor is connected with transmission shaft driven, transmission shaft is connected with the impeller be arranged in the pump housing, transmission shaft stretches in pedestal and is connected with electric motor drive, the transmission shaft between pedestal and the pump housing is arranged with pump housing connecting tube, is tightly connected between pump housing connecting tube and the pump housing; Pump housing connecting tube is provided with a water outlet, is tightly connected between the transmission shaft and pump housing connecting base of the joint of pump housing connecting tube and pedestal.
Technique scheme, in use, impeller coordinates with the pump housing, to be mingled with in the water extraction of a small amount of wool, due to when transmission shaft high speed rotating, wool can be fitted on the sidewall of transmission shaft, and because there is gap between transmission shaft and the pump housing, a small amount of water can from being pressed in pump housing connecting tube between the pump housing and transmission shaft, and get rid of from pump housing connecting tube No. one water outlet along current, effectively can avoid the impurity such as wool to carry out piling up and the situation of hanging that results in blockage at transmission shaft place, improve the usability of circulating water pump and sustainable workability, the rate of fault of equipment can be effectively reduced simultaneously, enhance productivity.
As optimization, the pump housing and transmission shaft joint are provided with copper sheathing, and copper sheathing is set on transmission shaft.Between the pump housing and transmission shaft, be provided with copper sheathing, copper sheathing has stronger wear resistance, and sealing is relatively poor, and facilitate the impurity such as wool along water from passing between the pump housing and transmission shaft, usability is superior.
At pump housing connecting tube, one end of pedestal and transmission shaft joint are provided with waterproof V-type circle, have supported flange in the outer installment of waterproof V-type circle, and by bolt by pedestal, being fixedly connected with between supported flange and pump housing connecting tube three.Carrying out between transmission shaft and the other end of the pump housing can effectively be closed by this structure, water effectively can be avoided to flow out from the end of pump housing connecting tube, thus improve the usability of equipment.
Blade on described impeller is arcuate structure.This structure can effectively avoid wool to be blocked between blade and the pump housing, and in blade rotation process, the wool between blade and impeller can be imported transmission shaft place, and be pressed in pump housing connecting tube, get rid of, improve the usability of equipment, avoid situation about blocking.
A described water outlet is arranged on the pump housing connecting tube of pump housing one end, and the pump housing connecting tube near pedestal one end is provided with No. two water outlets.When there are special circumstances in this structure, when being with the water of wool more, cannot discharge in time from a water outlet, then along with the rising of water level, part water and impurity can be got rid of from the upper end of pump housing connecting rod No. two water outlet, and then add it by the elimination ability of impurity, reduce the possibility of its blocking, improve the use persistency of equipment.
A described water outlet is greater than No. two water outlets.This structure can make a water outlet water outlet convenient, facilitates the discharge of wool and water.
The two ends of the transmission shaft in pedestal are provided with the combination of bearing and oil sealing.This structure can make transmission shaft more stable in rotation process, and stability is more superior.
The circulating water pump that the utility model obtains, when wheel rotation is drawn water, impurity in water can enter the joint of the pump housing and transmission shaft along blade, and under the effect of the pressure, impurity can from entering in pump housing connecting tube between transmission shaft and the pump housing, got rid of by a water outlet and No. two water outlets, can effectively avoid the accumulation of impurity and the phenomenon that results in blockage, hang, thus improve the use sustainability of equipment, working life increases, reduce maintenance cost, enhance productivity.
