Booster pump helps RO system keep production steady

A lot of areas use ro system to filter water, Specific energy consumption (SEC) for reverse osmosis (RO) desalination systems has usually been estimated using simplistic analyses that consider an average duty point of operation for a certain plant.
Amore sophisticated and comprehensive approach that accounts for the effects of variable parameters of operation on SEC was recently described, introducing the concept of the “hydraulic envelope”.
Variable parameters include flow rates at variable recoveries, feed temperature and salinity with their resulting pressure requirements, pressure losses caused by membrane fouling, and pressure losses caused by system controls such as feed throttle valves.
Particular attention will be paid to a recently developed, innovative energy recovery configuration that uses a motor-driven booster pump coupled to a Pelton turbine, the so-called ‘PROP’, instead of a single-component high-pressure feed pump. This new energy recovery concept can not only be applied to single-stage RO plants, but also as a highly effective interstage booster for dual-stage Brine Conversion Systems (BCS). The concept has been submitted for patenting. Results of the analysis suggest that the key issue for minimizing SEC is to control the plant over the entire width of the operational range without creating throttling losses. This can only be achieved by using hydraulic equipment that allows for feed pressure adjustment at minimum energy dissipation and eliminates the need for throttling valves. It is shown that the newly developed ‘PROP’ concept provides minimum SEC over the entire range of the hydraulic envelope of a plant, while at the same time allowing for maximum hydraulic dynamic control efficiency of the RO unit. In addition, the ‘PROP’ offers a significant savings potential in terms of capital costs compared to conventional energy recovery strategies.

Causes of Electric Motor Burning by Water pump

1. First, find out whether the motor burns the bearing (mechanical fault) or the coil (electrical fault). If it is the fault of burning coil, it is mainly caused by overcurrent, sometimes too high or too low voltage will also cause the coil to heat and short circuit, so check that the voltage when running is too different from the rated voltage.There may be several reasons for over-current short-circuiting: A. the equipment is overloaded to make the motor run for a long time at rated or over rated current. In particular, the starting current of the motor is 3-5 times that of the rated current. Therefore, we should try to avoid running with load or full load when starting the equipment (mainly depending on the matching allowance of rated current and normal operating current of motor). B, the motor works in a wet working environment. The insulation of the coils should be checked before the motor starts. The insulation requirements of different voltage grades are also different.

Several type of pumps for changing human life

Today we will talk about several type of water pump ,which changes our life. 1, Booster pump :The last decades,people who lives in high building can feel pains caused by the low water pressure,especially in rush hour.But now,the convenience booster pump takes to us become a part of our life. We nearly forget it exist.In nowadays,building is taller and taller,but even on the top of the high cloud bulding,the flow of water is also very stable and strong. 2,Ro booster pump:As ro technology developed,ro booster pump step into our daily life,since the pump appeared ,make water clean and safety is not a hard work,this type of pump helps a lot of people drink clean water,avoid disease,especially some people who is required only drink purified water,do not need to pay too much money to buy purified water,we can get it anywhere.Even in desert,bottle water can be brought easily.some sweet water purified by sea water,how magical pump is it? 3, Aquarium water pump ,fishes which we can see on...

How much is the stainless steel water pump?

We are very concerned about the price of the stainless steel centrifugal pump? How much money of stainless steel pump, in fact, this has a great relationship with product quality,some stainless steel pump like Grundfos,the price is higher, the quality is good. But there are also some stainless steel water pump,like Gelaili pump,the quality is good, but the price is not so high,it’s like buying a steak with the cabbage money. There are some small factories, the quality of their water pump production is not stable, the user experience is very poor, the price is very cheap, but in the process of using, maintenance costs have far exceeded the saved money when the pump was brought down. Therefore, how much is the stainless steel pump, really depends on the quality of the product, there is no enterprise willing to do business at a loss. How much is the stainless steel pump, stainless steel pump manufacturers and production experience affected price.Grundfos pump manufacturing history, c...
