Problems solved by technology

Commonly used mud plunger pumps to transport double-foam insulation slurry often cause solid-liquid phase separation of double-foam insulation slurry, which cannot guarantee the quality requirements of double-foam slurry on-line production
The use of ordinary single-screw pumps to transport double-foam insulation slurry often results in a high foam breaking rate of inorganic foam, which increases the bulk density and reduces the quality of double-foam insulation slurry.
Since the double-foam insulation slurry contains soft and hard particles such as organic foam particles and inorganic foam cement, using an ordinary single-screw pump to transport the double-foam insulation slurry is likely to cause wear and damage to the stator and rotor of the single-screw pump. Usually, the processing of the stator of the ordinary single-screw pump is to vulcanize the spiral groove rubber body and the metal jacket into one body, and its length is several times the pitch of the spiral groove, which is difficult to produce and process. Difficult installation and maintenance, long downtime, high cost of spare parts, unable to guarantee the quality requirements of on-line production of double-foam composite slurry, and unable to meet engineering needs
