ZJ, ZJP old Roots vacuum pumps are widely used in the manufacture of other occasions metals, non-metallic materials industry, vacuum degassing, vacuum melting, vacuum surface treatment and low-density wind tunnel testing and electrical equipment, vacuum freeze-drying equipment Roots vacuum pumps Price, the pump with water ring vacuum pumps, liquid ring vacuum pumps use Houluo Ci series configuration is more suitable for the chemical industry vacuum polymerization reaction, decomposition and vacuum distillation of the food industry, vacuum drying, vacuum crystallization process. Gas-cooled Roots pumping main structure: Bearings: a fixed axis uses double row angular contact ball bearings Roots vacuum production and supply, telescopic end uses roller bearings with high load capacity. These bearings can withstand high speed and load, in order to ensure that the gap between the gear and the rotor between. Seal: Roots pump seal with a two-way internal lip seal, can effectively prevent the flow of fluid two-way mutual, consistent fluid composition. Drive shaft seal using the oil seal.
