Analysis of shielding pump main features, structure, classification and application

In leak-free pumps, shield pumps are more widely used. Shielding pump with a stator winding and rotor windings were placed in a sealed metal cylinder motor drive shield, pump housing and drive motor housing flange seal connected to the pump to remove the pump shaft seal structure. Suitable for transporting valuable liquids or radioactive liquids. ? Structure type: 1, the motor and pump integrated structure, pumps and motors for the coaxial connection; 2, inside the motor stator and the rotor has a shield sleeve outside, inside the shield sleeve and pump connectivity; 3, the installation of sub-horizontal and vertical two 4, the motor to cancel the cooling fan, through the stator and the rotor between the circulating medium to cool the motor, while using the motor base surface cooling. ? Features: 1, motor and pump integration structure, all static seal, the pump is completely leak-free; 2, fully enclosed, non-leaky structure can transport toxic and hazardous liquid substances; 3, the use of shielded water-cooled motor and canceled the cooling fan to quiet operation of the pump low noise, suitable for high ambient noise requirements of the occasion; 4, the use of transport medium lubrication of graphite sliding bearings, lower operating noise and without artificial refueling, reducing maintenance costs; In recent years, the bearing material has increased silicon carbide SIC, superhard, better life than graphite bearings. 5, vertical structure can be installed on the pipe like a valve, easy and quick to install, and simply remove the motor and impeller can be repaired, without removing the pipe. 6, can be installed with shock absorbers or shock absorbers to run, so that pump noise in operation is lower. Electric pump shielding Specific forms: 1, conveying the basic type of ordinary materials; 2, Conveying reverse-circulation type and reverse-pressure type of easily vaporized materials; 3, conveying high-temperature materials, high temperature separation type, usually below 350 degrees temperature; ? 4, the delivery of the slurry material particles; 5, conveying high melting point material of high melting point type; 6, conveying material level lower than the pump suction self-priming type, self-priming height should be less than 5 meters. Shielded pump applications First, civil: 1, ground source heat pump air conditioning circulating water system; 2, Lithium bromide air conditioning unit air-conditioning pumps, transformer pumps, motorcycle pumps; 3, heating heating circulating water system; 4, fire water pressurization system; 5, tap water pressurization system. Second, industrial and military space: 1, chemical and pharmaceutical industries with toxic and hazardous liquid transport; 2, space rocket fired before the launch of fuel; 3, nuclear power plant nuclear shield pump.
