Problems solved by technology

[0003] However, there is a lack of systematic theoretical research on the hydraulic components used to reduce the vibration characteristics of the water supply system of the pumping station. Optimizing and rationally determining the design parameters of the air cushion surge chamber and the layout of the piping system are conducive to the vibration reduction of the system

Embodiment Construction

[0057] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0058] First, the working principle of the method of the present invention will be briefly described. Such as figure 2 As shown, the structure of the pumping station in the present invention includes a forebay, a first pipeline, an air cushion surge chamber, a second pipeline and a reservoir connected in sequence, and a water pump is installed on the first pipeline. In this system, the air cushion surge chamber plays the role of pressure regulation, so the air cushion surge chamber can be equivalent to a capacitor. The larger the flow capacity, the smaller the impedance, and the more significant the pressure oscillation effect of the absorption system.

[0059] Introduce parameter G(iω)=1 / Z m , which characterizes the degree of influence of concentrated components (surge chamber, blind leg, accumulator, etc.) on the dynamic characteristics of th...

Abstract

The invention discloses a pump station system vibration reduction measure and arrangement optimization analysis method, a pump station comprises a forebay, a first pipeline, an air cushion pressure regulating chamber, a second pipeline and a reservoir which are connected in sequence, and the first pipeline is provided with a water pump; the method is characterized by comprising the following steps: step 1, establishing a mathematical model of impedance of the air cushion type surge chamber by applying an electrical engineering principle and an equivalent capacitance and inductance theory; 2, solving the characteristic frequency of the system; and 3, introducing a disturbance item to carry out hydraulic vibration analysis on the pump station pressurized water supply system. According to therelation between the impedance modulus value and the vibration characteristic, through the expression of the characteristic frequency, the size parameter of the air cushion surge chamber and the arrangement of a pipeline system are reasonably optimized, and a theoretical basis is provided for reducing the vibration characteristic of a pump station system.

Description

technical field [0001] The invention relates to the field of pumping station systems, in particular to an analysis method for vibration reduction measures and layout optimization of the pumping station system. Background technique [0002] During the operation of the pumping station, vibration problems will inevitably occur. When the vibration exceeds a certain range, serious local damage or accidents will be caused, which will affect the safe operation of the pumping station. The current vibration reduction measures for the pressurized water supply system of pumping stations mainly use hydraulic components such as air cushion surge chambers and one-way surge chambers to adjust the local flow characteristics of the system, so as to achieve the effect of reducing vibration. [0003] However, there is a lack of systematic theoretical research on the hydraulic components used to reduce the vibration characteristics of the water supply system of the pumping station. Optimizing ...
