Description

Technical Field

[0001] This utility model relates to the field of submersible pump devices, and in particular to a high-sealing, leak-free submersible pump. Background Technology

[0002] Submersible pumps are mainly used in water supply companies, sewage treatment plants, steel mills, mines and other industrial and mining enterprises, as well as in municipal water supply and drainage, farmland irrigation, flood control and drainage projects. The pump body of a submersible pump is submerged in the medium, which is suitable for slurries containing a large number of particles. It can also be used in other chemical processes with a viscosity of less than 300 CP to transport corrosive or toxic solid viscous liquids. During the operation of a submersible pump, due to temperature and pressure, although a sealing device is installed at the pump shaft, the lubricating oil in the oil chamber will inevitably leak. The leaked lubricating oil will pollute the environment, increase energy consumption and losses, cause the transported liquid to denature and solidify, and may even cause equipment damage, thus posing a safety hazard to production.

[0003] The submersible pump includes a base, a motor, a pump body, and an extension pipe. The motor is fixed to the base and located above the liquid, while the pump body is fixed to the base and located below the liquid. The pump body is equipped with a flow channel, an impeller, and an impeller drive shaft. One end of the impeller drive shaft is located in the flow channel and is used to install the impeller. The other end extends to the impeller motor and is linked to the impeller motor through a coupling. The flow channel has an inlet and an outlet. When the impeller rotates, the medium is drawn in by the inlet and discharged from the outlet. The extension pipe is installed at the outlet.

[0004] Currently, although sealing devices are installed during the use of submersible pumps, lubricating oil leakage in the oil chamber is still inevitable during long-term use. Leaking lubricating oil pollutes the environment, increases energy consumption and losses, and during use, because the outlet pipe is located on one side of the device, the center of gravity becomes unstable and the direction is difficult to control during hoisting and extraction. Especially when mortar needs to be extracted in engineering projects, workers cannot enter the mortar pool and can only use a crane to lift and extract it with a submersible pump. At this time, it is difficult to control the direction of the submersible pump and determine the depth of submersible pump sinking, which may lead to safety accidents, causing personal injury and property damage.

[0005] Therefore, it is necessary to propose a high-sealing, leak-free submersible pump to solve the above problems. Utility Model Content
