Description
[technical field]
The utility model belongs to mechanical field, relates to a kind of starch pump, is specifically related to a kind of from cooling starch pump.
[background technique]
Oxytetracycline Base, in extraction production process, due to the High Rotation Speed of starch pump shaft, in order to improve working life and the working efficiency of starch pump, just needing to pass into cooling water to starch pump and cooling.Wherein every batch of material liquid process need use 4 starch pumps simultaneously, 12 hours are needed according to the process of every batch of material liquid, the cooling water 110kg that passes into per hour calculates, then every platform starch pump needs logical cooling water 12h*110kg=1320kg, namely 4 need cooling water 1320*4=5280kg, cooled water can not carry out secondary use, and this just causes the waste of water resources.
[summary of the invention]
For the problems referred to above, what the utility model provided cools starch pump certainly, in time using, do not need logical cooling water, both can realize, from cooling, solving the problem of water resource waste in prior art.
What the utility model provided cools starch pump certainly, comprising:
The pump housing;
Impeller, it is located in the described pump housing;
Pump cover, it is fixed at the side of the pump housing, and forms the pump chamber installing impeller between this pump cover and pump housing;
Intermediate, it is fixed between the pump housing and a bearing housing, forms machine sealing chamber between this intermediate and pump cover;
Axle, it is located in bearing housing by bearing, and one end of this axle is stretched in pump chamber through intermediate;
Sealing gland, it is fixed on pump cover, and described axle passes from sealing gland, form a gap between described pump cover and axle, be provided with seal arrangement in described gap, described seal arrangement comprises rotating ring and stationary ring, described stationary ring is fixed on axle, and described rotating ring activity is located on axle.
Especially, described sealing gland internal diameter extends a projection away from one end of rotating ring.
Especially, described rotating ring is provided with the breach corresponding with projection near one end of sealing gland.
Especially, packing ring is provided with between described step surface and sealing gland.
Especially, the material of described rotating ring and stationary ring is that stainless steel or graphitic carbon are brilliant.
Compared to prior art, the utility model provides a kind of from cooling starch pump, in use cools without the need to passing into water, namely the cooling of starch pump can be completed while feed liquid process, thus reach energy-saving and emission-reduction, the object of saving water resource, solve the problem of water resource waste.
[accompanying drawing explanation]

Working principle and working procedure:
Starch pump relies on rotary blade, to the effect of feed liquid, the mechanical energy of prime mover is passed to feed liquid, because effect feed liquid flows to the process of outlet from impeller inlet, its speed energy and pressure energy are all increased, the feed liquid of being discharged by impeller is through delivery chamber, major part speed can convert pressure energy to, then transfer out along discharge conduit, at this moment, impeller inlet place forms vacuum or low pressure because of the discharge of feed liquid, feed liquid in suction port material liquid tank is under the effect of liquid level pressure (barometric pressure), be pressed into the import of impeller, so, the impeller be rotating just continuously sucks and discharges feed liquid, thus complete the cooling certainly of starch pump.
It should be noted that; the foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
