Problems solved by technology

[0003] During the on-site production process, overflow water or tap water is usually used as the mechanical seal water of the paste underflow pump. Due to the large fluctuations in water quality and pressure of the overflow water or tap water, water cutoffs and excessive mud in the water often occur, causing the underflow pump to fail. Mechanical seal water cannot be added effectively, mechanical seal wear and other problems

Abstract

The invention provides an emergency mechanical-sealing-water adding device for a paste thickener underflow pump and belongs to the technical field of mineral engineering. The device comprises a water storage device, a water inflow solenoid valve, a mechanical-sealing-water adding solenoid valve, a manual waste water draining valve, a mechanical-sealing-water booster pump, a pressure meter, a controller, a water delivery pipe and an observation and exhaust hole. The water inflow solenoid valve, the observation and exhaust hole, the mechanical-sealing-water adding solenoid valve and the manual waste water draining valve are arranged on the water storage device. Mechanical sealing water is added into a mechanical seal of the underflow pump after being boosted by the mechanical-sealing-water booster pump, and the mechanical sealing water is drained and then delivered into the water storage device through the water delivery pipe for circulation use. The pressure meter monitors mechanical sealing water pressure, and the water pressure is controlled by controlling the water inflow solenoid valve and the mechanical-sealing-water booster pump through the controller. The emergency mechanical-sealing-water adding device is simple and reliable in structure, convenient to move and capable of achieving the purpose of mechanical sealing water adding of the paste thickener underflow pump in the emergency state effectively, and continuous normal operation of the underflow pump and a paste thickener is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of mining engineering, in particular to an emergency adding device for sealing water of an underflow pump of a paste thickener. Background technique [0002] The underflow pump of the paste thickener is the key equipment for the circulation and transportation of the underflow of the paste. If the underflow pump fails, it will inevitably affect the normal operation of the paste thickener. Underflow pumps usually use mechanical seals, in which pure water is passed to ensure the sealing effect. This water is called mechanical seal water. The mechanical seal water is used to cool and lubricate the heat generated by the static and dynamic rings of the mechanical seal during high-speed operation. At the same time, it can produce a water film between the dynamic and static rings to provide lubrication and prevent dry friction. [0003] In the on-site production process, overflow water or tap water is usually used as the ...
