Summary of the invention
The objective of the invention is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---the cemented carbide idle running amphibious vertical pump for mine of can connecting, it can make many vertical pump for mine concentrate in same place and be installed in series, also can space out on the way and disperse to be installed in series, its final effect is to be equivalent to the extra heavy water pump of a heaviness is broken the whole up into parts, be separated into a plurality of power less, the vertical pump for mine that weight is lighter, replace extra heavy water pump with serial fashion again, so that mobile in the tang carrying of down-hole, all difficulties be can overcome, high-lift sand discharge or emergency drainage task finished smoothly.
The cemented carbide idle running of the present invention technological scheme that amphibious vertical pump for mine adopts of can connecting is: the negative pressure of the water sucking mouth of vertical pump for mine is during near the cavitation transition point, there is the vertical pump for mine suction port safety valve that can prevent cavitation under negative pressure of automatic air amount the water sucking mouth, this moment the water sucking mouth the vertical pump for mine of suck air be 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, can be bottom valve, can be check valve, can also be one-way valve.In the water-filled situation of drainage pipe, can allow the water sucking mouth of vertical pump for mine of own anhydrous starting that the dewatering outlet should be arranged.Can allow the water sucking mouth of vertical pump for mine of own anhydrous starting should when the dewatering outlet is arranged, also have suction port.Can allow the water sucking mouth of vertical pump for mine of own anhydrous starting when the dewatering outlet is arranged, being preferably in this vertical pump for mine drain opening also will have suction port.The valve that check valve or cut-out drain opening path preferably also will be arranged above the vertical pump for mine drain opening that suction port is arranged.This moment, the vertical pump for mine of suck air was 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 that its water sucking mouth is equipped with after the safety valve of automatic air amount, vertical pump for mine row is dense just can frequent occurrence cavitation accident when husky, the vibration that therefore can avoid cavitation to cause.The vibration of exactly sand discharge that the vertical pump for mine of sand discharge is afraid of most because vibration can cause the cemented carbide choma to be shaken to be split and shake brokenly, can lure the larger accident of drawing.In the water-filled situation of drainage pipe, the vertical pump for mine water sucking mouth increases dewatering outlet and drain opening and increases after the suction port, can allow own anhydrous starting, and such starting current minimum is the most quick, the safest.
