Summary of the invention
The object of the invention is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---cemented carbide idle running can be connected amphibious vertical pump for mine, it can make, and multiple stage vertical pump for mine is concentrated in same place to be installed in series, also the dispersion that can space out on the way is installed in series, its final effect is equivalent to a heavy extra heavy water pump to break the whole up into parts, be separated into multiple power less, the vertical pump for mine of lighter in weight, extra heavy water pump is replaced again with serial fashion, so that mobile in the tang carrying of down-hole, all difficulties can be overcome, complete high-lift sand discharge or emergency drainage task smoothly.
The cemented carbide idle running of the present invention technological scheme that amphibious vertical pump for mine adopts of can connecting is: when the negative pressure of the water sucking mouth of vertical pump for mine is close to cavitation transition point, water sucking mouth have automatically suck air under negative pressure can the vertical pump for mine suction port safety valve of anti-cavitation, now the vertical pump for mine of water sucking mouth suck air is in the anhydrous idling conditions of permission.Vertical pump for mine suction port safety valve can be the safety valve of disclosed patent documentation ZL200410078876.4 vertical pump for mine in the past, and can be bottom valve, can be check valve, can also be one-way valve.In the water-filled situation of drainage pipe, the water sucking mouth of the vertical pump for mine of oneself anhydrous starting can be allowed to have dewatering outlet.The water sucking mouth of the vertical pump for mine of oneself anhydrous starting can be allowed should to also have suction port while having dewatering outlet.Can allow the water sucking mouth of vertical pump for mine of oneself anhydrous starting while having dewatering outlet, preferably also will have suction port in this vertical pump for mine drain opening.There iing the valve that preferably also will have check valve or cut-out drain opening path above the vertical pump for mine drain opening of suction port.Now the vertical pump for mine of suck air is in the anhydrous idling conditions of permission.
Can the connect advantage of amphibious vertical pump for mine of cemented carbide idle running of the present invention is after its water sucking mouth is provided with the safety valve automatically sucking air, would not frequently there is cavitation accident when arranging dense sand in vertical pump for mine, therefore can avoid the vibration that cavitation causes.The vibration of sand discharge exactly that the vertical pump for mine of sand discharge is afraid of most, splits shake broken because vibration can cause cemented carbide choma to be shaken, can lure the accident that extraction is larger.In the water-filled situation of drainage pipe, after increase dewatering outlet, vertical pump for mine water sucking mouth and drain opening increase suction port, can allow oneself anhydrous starting, such starting current is minimum, the most fast, the safest.
Accompanying drawing explanation
