The sealing gasket used by the mortar pump and the pipeline through which the air source is fed shall be made of non-toxic, tasteless, particle free and corrosion-resistant materials. The inner pressure bearing metal support framework is embedded in the pump casing, which limits the thermal axial expansion and compression axial compression permanent deformation of the full plastic pump casing, overcomes the shortcomings of the mechanical performance instability caused by the compression deformation and cold shrinkage deformation of the full plastic pump body, and effectively improves the operation stability of the full plastic corrosion-resistant and wear-resistant pump.
In the key parts easy to wear, suitable high wear-resistant materials are inlaid, which solves the problems of short service life and high operation cost of slurry pump in the high temperature leaching section of hydrometallurgy. It can transport all kinds of corrosive and abrasive slurry and clear liquid, especially hfm-i two-stage booster pump, which is especially suitable for the pressure feeding of mortar pump, so that the efficiency of mortar pump is high, the filtering effect is good, the water content of filter cake is small, the sealing of pump is good, the service life is long and the maintenance cost is low. The mortar pump is composed of motor, cycloid pin wheel reducer, opposite direct drive reciprocating transmission device and hydraulic working end. Flow ≤ 60m3 / h, lift ≤ 1.2MPa, suction ≤ 10m, temperature ≤ 80 ℃.
The mortar pump can resist all kinds of corrosive media (acid, alkali, salt) and organic solvents in a certain range of temperature and concentration. It can be immersed in 80 kinds of organic solvents at 20 ℃ and 90 ℃ for 30 days. There is no abnormal phenomenon in appearance and almost no change in other physical properties.
