What is the mechanical seal installation for insulation asphalt pump

Insulated asphalt pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or increase its pressure. The insulation pump consists of two enclosed spaces consisting of two gears, a pump body, and front and rear covers. When the gears rotate, the volume of the space on the disengagement side of the gears increases from small to large, forming a vacuum that sucks in the liquid. The volume of the space on the meshing side of the gears decreases from large to small, and the liquid is squeezed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the discharge port of a gear pump depends on the magnitude of the resistance at the pump outlet. For example, the NYP high viscosity pump adopts the principle of internal meshing, and its structure is that the inner and outer gear pitch circles are closely attached to one side, and the other side is“ Crescent Plate; Separated by two, gears rotate in the same direction, no trapped liquid phenomenon, structure, small volume, high flow rate, low noise, long service life. It is suitable for transporting light, volatile liquids, up to heavy, viscous liquids, and even semi-solid liquids.
