簡介 INTRODUCTION

VAS變頻式恆壓給水系統，利用變頻式控制器控制泵浦運作，達到省電力、壓力穩定運作平穩，壽命增加及施工
容易…等優點，亦可依現場實際需求設計控制流程，節省人力電力，目前已漸取代定速型加壓泵浦給水系統，被
VAS
廣泛使用於學校、工廠、大樓一般給水、工地給水、醫院…等水壓不足的場所。
The VAS system uses a variable frequency controller and interter-duty motors to control the pump operation to save power,
operatiing stably under pressure, keeping longer product life and constructing easily. System can be designed by the control process
according to the actual needs of the site, saving manpower and electricity, and it has replaced the fixed-speed pressurized pump water
supply system.The VAS system is widely used in schools, factories, buildings water supply, construction water supply, hospitals or other
places with insufficient water pressure.
特點 FEATURE

省電力、效率高、安全性高
採用變頻器控制回轉速變化，利用回轉速變化達到泵浦節省電力功能，提高整套系統使用效率，降低泵浦運轉費
用，變頻器內建多項保護裝置，開關為接點式，安全性高。
Power saving, high efficiency, high safety
The frequency converter is used to control the change of the r.p.m., and use this change of the cadence is used to achieve the power saving
function of the pump and improve the efficiency of the entire system. Reduce pump operation costs, The frequency converter is set multiple
protection devices and it is high security that the switch is a contact type.
給水壓力穩定
採用變頻器與壓力比例器控制，依使用壓力變化經感測器感應傳輸信號至壓力比例器控制壓力，保持恆壓設定值
1 ，給水壓力穩定，完全改善定速泵因壓力不穩定而水量忽大忽小的現象。
Water supply pressure Stably
Using inverter and pressure proportional control, according to the pressure changed, the sensor transmits the signal to the
pressure proportional controller to control the pressure. Maintaining constant pressure setting value and the water supply pressure stably,
and water volume of the fixed-speed pump fluctuates due to unstable pressure is improved.
啓動、停止平穩、增加泵浦壽命
泵浦啓動和停止，利用變頻方式平穩運作，減低泵浦啓動頻繁對系統之影響。停止時，系統經感測器感應壓無變
化、無使用水時，泵浦能緩慢停機，無水槌現象發生，降低管路漏水機會，泵浦壽命增加。
Start and stop smoothly, extending pump life
Pump start and stop, operating smoothly with frequency conversion, reducing the impact of frequent pump start on the system. When the
system stops, the pressure of the system through the sensor does not change and there is no using-water, the pump can stop slowly with
no water hammer occurs, which reduces leakage of pipeline water and extends the pump life.
施工容易、安裝簡便、節省空間
本系統泵浦、管路、控制箱安裝於共同機座，施工時只需安裝入、出水管及電源即可運轉使用，壓力桶容積較定
速泵浦小，節省裝置壓力桶空間。
Easy construction, simple installation, and space saving
The pump, pipeline, and control box of the system are installed on the same baseplate. During construction, only the inlet and outlet pipes
and power supply are installed that be able to operate. The volume of the pressure tant is smaller than the fixed-speed pump, which saves
space for installation of pressure tant.
