Low porosity clay bricks are made of ruby, mullite and combined clay as the main raw materials, molded under high pressure and sintered at high temperature. The product has excellent high temperature Physical properties and chemical corrosion resistance. Low porosity clay bricks have good stability, the degree of erosion does not occur sudden change, than ordinary clay bricks use cycle increased 2-3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks higher than 50% -60%, can improve the thermal efficiency of the kiln.

Shielded pump the specific form and application areas (Figure)
Common centrifugal pump drive is through the coupling of the pump impeller shaft and the electric shaft connected to the impeller and the motor together to rotate work, and the shield pump is a non-sealed pump, pump and drive motor are sealed in a Pumped medium filled pressure vessel, the pressure vessel is only static seal, and by a wire group to provide a rotating magnetic field and drive the rotor. This kind of structure has canceled the rotary shaft sealing device that the traditional centrifugal pump has, therefore can be completely leakless. Shield pump to pump and motor together, the motor rotor and pump impeller fixed on the same axis, the shield sleeve motor will be separated from the stator and rotor, the rotor is transported medium, the power through the stator field Pass to the rotor. In addition, the shield pump manufacturing is not complicated, the hydraulic end of the centrifugal pump can be used in accordance with the structure type and the relevant standard specifications to design and manufacture. Shielded electric pump in the specific form: 1, the basic type of conveying ordinary materials; 2, conveying easily vaporized material reverse circulation and reverse pressure type; 3, conveying high temperature materials, high temperature separation type, the temperature is usually below 350 degrees; 4 5, the high melting point type conveying high melting point material; 6, the conveying material level is lower than the self-suction type of the pump inlet, the height of the self-absorption should be lower than 5 meters. Silent household shielded booster pump shielding electric pump applications: a civilian 1, ground source heat pump air conditioning circulating water system; 2, lithium bromide air conditioning unit air conditioning pump, transformer pumps, locomotive pumps; 3, heating heating circulating water system; 4 , Fire water booster system; 5, tap water booster system. Second, industrial and military aerospace 1, chemical and pharmaceutical industries with toxic and hazardous liquid transport; 2, space rocket launch fuel before refueling; 3, nuclear power plants with nuclear-screened electric pump.
