(1) PS type sand pump is a horizontal side-stage centrifugal centrifugal sand pump. The maximum concentration of pulp can be 60%~70% (mass) when transporting pulp with the slurry of the slurry of the ore dressing plant and the medium of heavy medium dressing. The shaft seal is in the form of low-pressure packing. It needs to be cooled and lubricated with a small amount of water during operation. With the press-in configuration, the center line of the pump shaft is lower than 1m on the pulp surface [4];
(2) PH type sand pump is a horizontal single-stage single-suction cantilever type centrifugal ash pump, which can transport mixed liquid containing sand and gravel (maximum particle size not exceeding 25mm), and can allow sandstone with a small particle size of about 50mm to pass intermittently. . The shaft seal is sealed by a general packing, and the shaft seal water is injected at a working pressure higher than 98 kPa.
(3) PN sand pump is a horizontal single-stage single-suction cantilever centrifugal mud pump for conveying slurry. The maximum concentration (mass) is 50%~60%. The shaft seal is made of general packing, and the shaft seal water is injected at a working pressure higher than 98 kPa. (4) PNJA and PNJFA type sand pumps are all horizontal single-stage single-suction heart-type rubber-lined pumps. The PNJFA model is designed to transport corrosive pulp. They can be used to transport a variety of pulp, but it is not advisable to transport a slurry containing sharp-angled solid particles. The maximum concentration of the transported slurry shall not exceed 65% (by weight), the temperature shall not exceed 60 C, and the press-in configuration shall be adopted, and the water shall be sealed.
(5) PNL sand pump is a vertical single-stage centrifugal mud pump, which can be used to transport slurry in the concentrator. The maximum concentration (mass) is 50%~60%.
(6) PW type pump, horizontal single-stage cantilever centrifugal sewage pump, suitable for conveying liquid and sewage with fiber or other suspended matter below 80 C, but not suitable for transporting acidity, alkalinity and causing metal corrosion Chemical mixture of liquids. In order to prevent the sewage from leaking along the shaft, a water seal is required, and the pressure should be higher than the pump outlet pressure.
(7) PWF type pump is a horizontal single-stage single-suction cantilever centrifugal corrosion-resistant sewage pump, suitable for discharging acidic, alkaline or other corrosive sewage. The liquid temperature is within 80 C; it needs to be sealed, and its clear water pressure is high. Working pressure
There are two kinds of seals from 49~98 kPa (0.5~1.0kg/cm2): mechanical seals (single end face) and general packing seals to prevent toxic, highly corrosive liquid leakage.
( Long-axis vertical centrifugal pump (commonly known as long-axis pump) is a special pump for transporting pulp, coal slurry and various flotation foams and medium-mineral products from the concentrator. It can also transport other liquids and sewage. It is a large-scale flotation. One of the indispensable supporting equipments in the production of the plant enables the flotation plant to realize flexible control of the circuit.
(9) Foam pump, which is a vertical centrifugal sand pump, has defoaming effect, and the defoaming rate is generally above 75%. It can be used for defoaming and conveying before concentration dehydration, reducing metal loss in concentrated overflow, and can be used for foam products. Delivery.
