Description

technical field [0001] The invention relates to an emergency gas energy multifunctional water purification system, in particular to an emergency gas energy mobile water purification system that does not consume electric energy, and belongs to the technical field of environmental protection. Background technique [0002] With the rapid development of the current society, environmental pollution is becoming more and more serious, and the earth we live on has become riddled with holes. For the sustainable development of the ecological environment, the whole world is taking action to advocate low-carbon energy saving, energy saving and emission reduction have become A must for any business. As a water pump that consumes 20.9% of the national industrial electricity consumption, it has a broad space for energy saving. [0003] For a long time, submersible electric pumps have played an indispensable role in the fields of water supply and drainage of industrial and mining enterpris...

AI Technical Summary

Problems solved by technology

The working mode remains the same. The motor rotates to drive the impeller to pump the water up. Because the rotation is required to do work, the seal cannot be 100% and the head of the water pump is limited. To increase the head, the power of the motor must be increased. In order to lift the water higher, because the motor is soaked in water all the year round, the rust prevention of the shell and the motor core has always been a headache for people, and the submersible pump is often lifted from the well. At that time, it has been scrapped, rusted into an iron lump, and there is still some pollution to the water source. This is only a rust prevention problem, and there is also a problem with the insulation of the motor. The motor of the submersible pump is wound with a special enameled wire to prevent leakage. , but due to the long-term high-pressure immersion in water, the vibration and friction of the motor itself when it is working, so leakage is a common thing, and the energy is wasted

There is also the problem of vulnerable bearings. After the bearing is broken, the motor cannot rotate normally, and the water pump will burn out. There is an oil-immersed submersible pump that is better, but the seal must be very good, otherwise the water pump will leak oil or It's the water pump that's deadly.

Therefore, it is stipulated in the industry that submersible pumps need to be maintained and overhauled for about 2,000 hours of operation, which is troublesome, laborious, and delays work.

Another fatal weakness of the submersible electric pump is that the power consumption is too high and it is not energy-saving, because when the submersible pump is running at high speed, it must first overcome the friction and resistance of the water to the rotor. If it is an oil-immersed submersible pump, it will be even more powerful, because The viscosity of the water is higher than that of water. This phenomenon has a great impact on the efficiency of the submersible pump. Just like a person walking in the water, the water hinders the feet and legs. To overcome the resistance, it is necessary to use more force. For submersible pumps, it is necessary to increase the power of the motor and consume more power

So it affects the conversion efficiency of the submersible pump

[0004] The above mentioned are some defects of submersible pumps, but these are some defects known in the pump industry, and it is a worldwide problem. So far, there is no good way to improve it. Yiyang Technology Co., Ltd. in Tai'an recently designed a [Magnetic levitation submersible pump] The use of magnetic bearings to replace the original ball bearings reduces friction and solves the problem of vulnerable bearings. It is a major innovation in the submersible pump industry, but other problems have not been completely changed.
