Description
Technical field
The present invention relates to a kind of pump for liquid salts, is a kind of high-temperature melting salt pump with better heat dispersion specifically.
Background technique
Pump for liquid salts is the pump that is used for carrying high-temperature molten salt specially, surpass more than 100 ℃ for the fed sheet of a media temperature, heat generally is by main shaft or connection support elevated temperature heat to be passed to bearing portion, thereby can cause bearing lubrication to be lost efficacy in advance and the trigger pump operation troubles, must effectively cool off positions such as bearings immediately the high temperature media transfer pump.Traditional cooling means comprises: 1, adopt water-cooling jacket Forced water cooling main shaft to dispel the heat, at the pump shaft that uses under the hot environment, the required cooling water inflow that dispels the heat is big, the external equipment load is big, in a single day external equipment breaks down, bigger to the pump for liquid salts systematic influence, water-cooled is bigger to the environmental protection influence simultaneously; 2, adopt band fan heat radiation bearing housing, to the bearing gland cooling of dispelling the heat, but heat is passed to bearing by fused salt through pump shaft, bearing is dispelled the heat, the passive heat radiation of bearing, bearing is in the repetitive cycling of heat absorption, heat radiation, bigger to damage of the bearing, working life is short; 3, adopt the cooling of oil pocket lubricant oil, establish cooling coil cutting oil or outer circulation cooling in the lubricant oil, there is the deficiency of water-cooling jacket equally in this method.
Summary of the invention
The deficiency that exists in the cooling means at high-temperature melting salt pump pump shaft or bearing in the prior art, the invention provides a kind of simple in structure, initiatively cool off pump shaft, good heat dissipation effect, can effectively avoid bearing to bear elevated temperature heat, prolong bearing working life, guarantee the high-temperature melting salt pump of high-temperature melting salt pump stable operation.
The technical solution used in the present invention is: a kind of high-temperature melting salt pump, comprise motor, the pump housing, impeller, pump shaft, bearing housing, middle frame and base plate, motor is connected on the bearing housing through the motor frame, motor connects pump shaft through coupling, bearing housing is connected in base plate one side by middle frame, the pump housing is connected in the base plate opposite side, pump shaft one end is bearing on the bearing housing through bearing, the impeller of the other end in impeller nut is connected in the pump housing, its technical characterstic is that pump shaft is provided with the heat dam group in the described middle frame, the heat dam group comprise multiple tracks along the heat insulation annular groove of pump shaft circumferencial direction and/or along pump shaft axially around the heat insulation spiral chute of pump shaft circumference.
Further, be socketed with the water-cooling jacket more than on the described pump shaft, the water-cooling jacket disjunctor is located at middle frame near base plate one end, or water-cooling jacket is located at middle frame one end away from base plate, or the water-cooling jacket disjunctor is located in the bearing housing.
Further, the described pump housing is communicated with the drain pipe that is fixed on the base plate.
Further, described middle frame is the open linking body structures of many columns, and many columns are provided with heat dam group and groups of fins.
Adopt technique scheme, the beneficial effect that the present invention reaches is:
1, in the middle frame pump shaft surface design multiple tracks along the heat insulation annular groove of pump shaft circumferencial direction and/or along pump shaft axially around the heat insulation spiral chute of pump shaft circumference, heat insulation annular groove or heat insulation spiral chute can effectively hinder slow or blocking-up high temperature media heat from the rapid transmission on pump shaft surface;
2, the middle frame support adopts the open linking body structure of many columns, under the prerequisite that does not influence mechanical strength, can reduce to greatest extent by connecting support and transmit the temperature rise that heat causes; Connect base plate on the pump shaft, the bearing place arranges cooling jacket, to the further heat radiation of pump shaft surface, improves radiating effect.
The pump shaft of the present invention between the high-temperature melting salt pump pump housing and bearing housing adopts thermal resistance fault trough heat shielding radiating structure, the disconnected design of opening, thermal resistance and the pump shaft cooling water jecket of support are connected, realize heat radiation and the blocking-up of pump shaft surface heat of high temperature, it is simple in structure, initiatively cool off pump shaft, good heat dissipation effect can effectively avoid bearing to bear elevated temperature heat, prolong bearing working life, guarantee high-temperature melting salt pump stable operation.
