Optimizing energy costs for pumping hydraulic stepless

2014-01-07

Energy consumption is a major factor in the operating costs of equipment and plants. Energy accounts for about 20-30% of total operating costs. And the application stepless hydraulic pump quickly overcome this costly, help save energy.

Stepless hydraulic pump provides enough energy that the Executive department needs , reducing energy costs up to 80 % .

Energy consumption is a major factor in the operating costs of equipment and plants . Energy accounts for about 20-30 % of total operating costs . And the application stepless hydraulic pump quickly overcome this costly , help save energy .

1.Bom stepless with constant speed pump

The traditional hydraulic pumps operate at constant speed to produce the power needed to operate the machine . And often , the rotational speed at 1500 r / min . And pump produces a much higher energy or produce energy without fixed interest rate of actual equipment needed from time to time . And fluid flow velocity changes based on the fixed adjustment valves and related fluid flow will be returned to the tank .

A new invention of hydraulic pump with stepless speed change system optimum pump , usually provided in speed can reach 200 vong/phut- while still providing enough power for the equipment necessary being active , reducing energy consumption to 30-80 % , but not limited to the working pressure .

With less energy consumption also help reduce CO2 emissions and contribute to reducing emissions from the company . At the same time the low speed operation reduces noise up to 20dB ( A ) . Helps reduce the health impact due to noise in the workplace and restricting equipped with protective equipment and help reduce unnecessary costs for equipment noise , sound insulation , sound absorption , ...

Due to the low power consumption low heat production , the fluid flow will not overheat , in many cases , you can remove the heat exchanger or fan cooling system unnecessary . And from there , allowing the design of more compact systems , reducing system complexity and investment costs . The construction of the system becomes easier and faster, less damage and easier to maintain .

In summary , the structure is changing pump speed can be integrated into existing equipment without having to re-design , which improves the performance of machines and plants .

2.The this type of pump on the market

There are many types of pumps and many manufacturers have been involved in the production of motors and pumps on the market and it seems more and more developed . For example : Sytronix of Rexroth products have 140 modules and is divided into 3 main categories for use in the system need constant pressure , pump system and create tension gripped as in machine tools , and Specially manufactured for heavy duty .

SVP - 7000 pump with servo motor and circuit board speed control offers precision pump from time to time

The board comes calculates the best speed for the pump and motor . And maintain the speed of 300-400 rpm / min , and when problems or sudden stop , the electronic system also stop the pump without impact on the working pressure .

3.Ung main advantage

It's not always possible to use this type of pump that engineers must take into account the cycle of machine operation , quality requirements , and energy consumption of the system ... The system as running in no load conditions or run a pump load , the priority will be used . And we save a lot of energy to the industrial sector such as machine tools , plastic processing machinery , molding pressure , presses , wood processing and paper .
