Suggestion on the efficiency of sewage pump and slurry pump

<

Commonly reported in some literature its sewage pump and slurry pump has a high water efficiency, and some even close to the efficiency of the water pump, I have the following views:


(1) With the continuous improvement of theoretical research and the continuous deepening and accumulation of experimental conclusions, especially the application of two-phase flow theory, it is inevitable that the efficiency of sewage pumps and slurry pumps should be constantly improved.

(2) Ordinary water pumps are designed for maximum efficiency, that is, the hydraulic structure parameters of a water pump are the best combination for maximum efficiency. For sewage pumps, slurry pumps and other special requirements of the pump efficiency can not exceed the same period of the efficiency of the pump. This comparison refers to the advanced level of contemporary rather than a person's level of design.

(3) sewage pump, slurry pump efficiency is lower than the main reason for the pump is their over-flow channel widened. The decrease in efficiency is mainly related to the degree of broadening. Therefore, it is pointless to compare the efficiency of two different sewage pumps and slurry pumps (Q, H, n) without the limitation of capacity.

(4) The widening of the sewage pump runner is to prevent clogging, so the efficiency of the original sewage pump is usually lower than that of the secondary sewage pump.

According to the statistical results of the efficiency of the sewage pump with φ / DS = 0.6 ~ 0.8 and Q <600m3 / h, the author gives the efficiency formula under this condition [1]

η = 0.78- (6.74Q) -0.32-0.29 (0.32-lg 0.013 ns) 2

Where Q - flow, m3 / h.

φ - pump allows the size, mm.

(5) The increase of mud pump runner mainly reduces the flow rate of two-phase flow in the runner to reduce the wear. Therefore, the strong abrasive slurry pump efficiency is usually lower than the efficiency of the soft mud pump. Such as Zigong Industrial Pump Co., Ltd. produced NG, ND pump is used for strong abrasive slurry, NQ pump is used to pump light mud.

(6) It is suggested that given the efficiency of the sewage pump and the slurry pump, the minimum passing size is given to facilitate the comparison of the pump design level.

It is suggested to establish the relationship of η = f (Q, ns, φ) sewage pump and slurry pump by experiment.

Aluminum Baler

The trends of the Aluminum recycling industry

Unlike many other materials, aluminum more than pays for its own recycling in the consumer and industrial waste. because the demand for aluminum continues to rise and recycling aluminum saves more than 90 per cent of the energy required versus producing new metal.
The economics of aluminum contributes to its position as one of the most recycled metals in the World.


What is the role of Metal Baler in Aluminum recycling?

The Aluminum scrap can be directly pressed into bales by using the Aluminum Metal baler from China factory YMSRECYCLING to make the high efficient metal recycling and increase the value of residual steel scrap.

Recycling metals also requires less energy than producing new metals. Also conserves natural resources. Recycling conserves diminishing natural resources.
