The Mechanical Seal Of The Solid-liquid Mixing Pump Is A High-precision Component
Solid-Liquid Mixing Pump adopts a unique single-blade or double-blade impeller structure, which greatly improves the dirt passing capacity. It can effectively pass through fibrous materials 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter. The mechanical seal adopts a new hard and corrosion-resistant tungsten carbide material. At the same time, the seal is improved to a double-end seal, so that it can operate in the oil chamber for a long time, which can make the pump run safely and continuously for more than 8,000 hours.
The solid-liquid mixing pump is a broken structure. When working, the pump body is immersed in the liquid, so it is easy to start, there is no problem of exhaust and evacuation, and there are characteristics such as no leakage. The liquid depth can reach 0.5-7 meters. The overall structural design is reasonable, the noise is low, the energy-saving effect is obvious, the inspection is convenient, the shaft connection structure is improved and reliable, the pump and the motor are connected by a flexible coupling, the pump shaft size is fine, which ensures the stable operation of the pump and leaves enough insurance system.
The mechanical seal of the solid-liquid mixing pump is a high-demand precision component, which has high requirements for design, machining, and assembly quality. When using mechanical seals, various factors of the use of mechanical seals in submerged sewage pumps should be analyzed to make the mechanical seals of submerged sewage pumps suitable for the technical requirements and medium requirements of various submerged sewage pumps and have sufficient lubrication conditions, so as to ensure the long-term and reliable operation of the seals of submerged sewage pumps. There are still unreasonable aspects in the design, selection, and installation of mechanical seals in submerged sewage pumps.
The mechanical seal of solid-liquid mixing pumps is also called end face seal. It has a pair of end faces perpendicular to the axis of rotation. Under the action of fluid pressure and compensating mechanical external elastic force, the end face of the submerged sewage pump relies on the cooperation of auxiliary seals to keep in contact with the other end and slide relatively, thereby preventing fluid leakage.
(1) The spring compression amount of the solid-liquid mixing pump must be carried out according to regulations, with an allowable error of ±2mm
(2) The end face of the shaft (or sleeve) where the dynamic ring seal of the solid-liquid mixing pump is installed and the end face of the sealing cover (or housing) where the static ring seal is installed should be chamfered and polished to avoid damaging the dynamic and static ring seals during assembly.
