Problems solved by technology

The production rhythm of the stainless steel pickling production line is relatively slow, the maximum operating speed of the unit is often below 200m / min, and the effective working time of the hydraulic station only accounts for 3-30% of the total operating time, so the actual no-load energy consumption of the system accounts for a large proportion

Embodiment Construction

[0024] The invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0025] The basic component of the new hydraulic station. Such as figure 1 As shown, the energy-saving hydraulic station is composed of basic units such as main working pump unit I, auxiliary working pump unit II, system pressure detection unit IV, hydraulic energy storage station unit V and system electronic control unit VI; in addition, it can be selected according to actual conditions On-board backup pump unit III and recirculation filter unit.

[0026] Among them, the main working pump unit I, auxiliary working pump unit II, and standby pump unit III are connected in parallel, and the output pipeline is connected to the control valve table. The detection point of the pressure detection unit IV is connected to the output pressure pipeline, and the output control signal is used to directly or indirectly control the auxiliary pump. The working p...

Abstract

The invention discloses an energy-saving method of stainless strip acid cleaning continuous annealing process line fluid-pressure station, which is characterized by the following: comprising the fluid-pressure station as master work pump unit I, assistance work pump unit II, fluid-pressure storage station unit V, pressure checking unit IV and electrical control unit VI; optimal-combining the system to decrease installed capacity of the master work pump I with maximum limit; shortening work time of the assistance work pump II with maximum limit; decreasing open circuit losses of the system; reaching the goal of energy-saving; reaching above 50% of integrated energy-saving effect.

Description

technical field [0001] The invention relates to the technical field of an energy-saving method suitable for a hydraulic station of a stainless steel plate (coil, strip) pickling production line. Background technique [0002] The hydraulic equipment equipped in some heavy industries is increasingly facing the development of large-scale and complex. Many hydraulic stations carry dozens or even hundreds of loads. In order to meet the complex and changeable production needs, the hydraulic system The situation of external work has also become complicated and changeable. For such a hydraulic system, we not only require stable and reliable operation, but also require energy saving as much as possible. [0003] However, the current hydraulic energy-saving technology is too rough to deal with such problems, and the effective utilization rate of energy is still very low. For example: In recent years, the stainless steel industry has been widely developed in my country, but due to sp...
