Ship desulfurization pump

Abstract

The invention relates to a ship desulfurization pump. The ship desulfurization pump comprises a motor, a motor bracket, a first bracket, a first coupling, a bearing gland, a sealing ring, a bearing, an oil seal, a bearing box, a second bracket, a filler gland, a filler base, a filler, a liquid outlet, an upper shaft, an inner pipe, a second mechanical seal, a pressure relief port, a second coupling, a third bracket, a center shaft, a pump shell, a third mechanical seal, a guide blade, an impeller, an impeller nut, a filter cover and a heat dissipating part. The ship desulfurization pump is provided with a circular cavity in the bearing box for continuously injecting in clear water from a water inlet and draining from a water outlet to prolong the service life of the bearing in the position, meanwhile, is provided with a fan below the bearing box for achieving the effect of further dissipating head, and is provided with the pressure relief port in the second mechanical seal for safely discharging exposed liquid to prolong the service life of the mechanical seal.

Description

technical field [0001] The invention relates to a desulfurization pump, in particular to a marine desulfurization pump. Background technique [0002] Sulfur is an element whose physical properties change significantly with temperature. Sulfur is solid at room temperature, and its fluidity increases after heating. It appears as a liquid at 113° and has the best fluidity at 130° to 160°. Currently, the need for energy is driving the search for oil of all tastes and compositions, and since most of the crude oil found is acidic, sulfur production has increased dramatically and producers have had to transport sulfur to off-site locations, often Sulfur is transported in liquid form, which not only reduces production costs, but also facilitates the use of enterprises. [0003] The desulfurization pump is a pump with corrosion resistance, mainly used for the transportation of corrosive liquids such as sulfur. At present, the mechanical seal device of the desulfurization pump on the...

Problems solved by technology

[0003] The desulfurization pump is a pump with corrosion resistance, mainly used for the transportation of corrosive liquids such as sulfur. At present, the mechanical seal device of the desulfurization pump on the market is simple in structure, and generally leaks under negative pressure conditions, which affects the service life of the desulfurization pump. , and the transported sulfur is a high-temperature liquid, long-term work will make the temperature of the bearing too high, which requires the desulfurization pump to have good heat dissipation performance
