3. Scope of application
2SK series double stage water ring vacuum pumps are widely used in light textile, food, metallurgy, chemical and other industrial sectors. For vacuum evaporation, vacuum concentration, vacuum moisture regain, vacuum drying, vacuum smelting and other industrial processes.
4. Product Features
(1) During the working process, the work will generate heat, which will heat the working water ring, and some water and gas will be discharged together. Therefore, during the working process, the pump must be continuously supplied with water to cool and supplement the water consumed in the pump.
(2) Mechanical seal can be used for sealing, which is installed in the packing chamber, and the packing is omitted. The packing gland is replaced with a mechanical seal gland, and the other structures are the same as those of the packing seal.
(3) A disc is installed on the end cover. The disc is provided with a suction hole, an exhaust hole and a rubber ball valve.
