The mining multi-stage centrifugal pump and the wear-resistant explosion-proof centrifugal pump are described in detail as follows:
Mining multi-stage centrifugal pump, wear-resistant explosion-proof centrifugal pump:
The DM type multi-stage centrifugal pump is suitable for water supply and drainage in mines, factories and cities. It is used to transport clean water without solid particles or liquid with physical and chemical properties similar to clean water. The temperature of the medium to be transported is 0 °C ~ 80 °C.
DM type multi-stage centrifugal pump parameters range: Flow Q 10~500m3/s Head H 33~850m DM type wear-resistant explosion-proof centrifugal pump Model Description: There are three types of DM type pump in the model representation method, which are described as follows: 1 DM280-43/84×5 “DM”- indicates a multi-stage mining centrifugal pump. "280" - indicates the flow rate of the pump (m3/h). "43" - indicates the single stage head (m) of the pump. "84" - indicates the year number. "5" - indicates the number of stages. 2) DM80-30×5 “DM”- indicates a multistage mining centrifugal pump. "80" - indicates the suction port diameter (mm) of the pump. "30" - indicates the single stage head (m) of the pump. "5" - indicates the number of stages. The pump represented by this method is only D80-30. 3) 150DM30 × 5 "150" - indicates the suction port diameter (mm) of the pump. "DM" - indicates a multistage mining centrifugal pump. "30" - indicates the single stage head (m) of the pump. "5" - indicates the number of stages. DM type mine explosion-proof centrifugal pump structure type: DM type pump is horizontal installation. Except for the direction of the suction port of the DM16-60 pump, the direction of the suction port of the other pumps is horizontal. The discharge direction of all DM pumps is vertically upward. The axial force is balanced by the balance disc. The shaft seal is generally sealed with a packing, and a mechanical seal can also be used according to the needs of the user. Except DM85-67, DM155-67 type pump adopts sliding bearing and thin oil lubrication, and the other uses rolling bearing and grease lubrication. DM type explosion-proof multi-stage centrifugal pump rotation direction: See clockwise rotation from the motor end to the pump. Main parts of DM type wear-resistant multi-stage centrifugal pump: The material of the pump's over-current parts is cast iron, and the material of the shaft is 45 steel. DM type multi-stage centrifugal pump for mining: The pump is supplied with the motor and the base. It can be equipped with a base or its own base. The factory also provides accessories (including spout cone, gate valve, bottom valve, check valve) and spare parts ( Including impeller, seal ring, vane sleeve, balance disc, bushing).
