     噴泉泵其實就是一種井用潛水泵,是專門為農用排灌、噴灌,工業及民用建筑的排水系統研制,適用于池塘、養魚池,水塔、深井提水和高樓送水。

      水景噴泉對電機的耐腐性很高,通常采用全不銹鋼或高科技材料,葉輪采用的也是專用材料以防止葉輪松動,并有專門的定電位接地裝置實施漏電保護,泵體還有不銹鋼濾網護罩和三相四線電纜。因為音樂噴泉需要隨著音樂節奏忽高忽低,不斷改變形態,專業水泵公司也在原來普通噴泉泵的基礎上不斷進行技術研發,使泵可以頻繁啟動,完全滿足噴泉的使用。同時,越大的噴泉面積對噴泉泵的功率要求也越高,為滿足各式各樣的噴泉,市場上立式臥式噴泉泵的規格型號十分齊全。

      使用噴泉泵時,有幾點需要特別注意:

      1、設備接地:

      為保證噴泉使用時的人身安全,國家對潛水泵的強制性標準的要求就是采取保護接地,否則一旦泵殼漏電,泵出水口附近的水以及蓄水池水面就會帶電,嚴重危及人畜的安全,也會造成電能的浪費。

      如果將噴泉泵的金屬外殼與符合國家標準的接地體(接地電阻不大于4Ω)接地連接,漏電時,電流經泵殼、地線、接地體、地、變壓器的工作接地線和電源形成一個閉合回路,一旦漏電電流過大,就是使泵的保護裝置工作——熔斷器熔斷或空氣開關跳閘,自動斷開噴泉泵的電源。

      2、安裝漏電保護器:

      一旦漏電危機發生,只要漏電值超過漏電保護器的動作電流值,通常不超過30mA,漏電保護器就會工作,斷開開關,使噴泉停止運行。

      3、電源電壓異常時開機:

      作為潛水泵,電壓過高、過低都會使泵體溫度上升,縮短泵的使用壽命,甚至燒壞,而現在在很多地方都存在低壓供電線路較長或者線路始端電壓過高、終端電壓過低的問題。因此噴泉運行時,操作者應時刻關注電源電壓值,當電源電壓值高于額定電壓10%或低于額定電壓10%,以及電流超過額定電流20%時,都要立即停機,避免電壓異常時開機。

      4、電機反方向旋轉:

      雖然有些噴泉潛水泵可以正反向雙出水,但是由于反轉出水量小電流大,所以反轉時間過長也會損壞電機。

      5、避免長期超負荷工作

    Fountain pump is actually a kind of well used submersible pump, which is specially developed for agricultural drainage and irrigation, sprinkler irrigation, industrial and civil building drainage system. It is suitable for ponds, fish ponds, water towers, deep wells and high buildings.

    The water feature fountain has a high corrosion resistance to the motor, usually made of all stainless steel or high-tech materials. The impeller is also made of special materials to prevent the impeller from loosening, and has a special constant potential grounding device to implement leakage protection. The pump body also has a stainless steel screen shield and three-phase four wire cable. Because the music fountain needs to change its shape with the music rhythm changing from high to low, and the professional water pump company also conducts technical research and development on the basis of the original ordinary fountain pump, so that the pump can be started frequently, fully meeting the use of the fountain. At the same time, the larger the fountain area, the higher the power requirements of the fountain pump. In order to meet the requirements of various fountains, the vertical and horizontal fountain pumps on the market have complete specifications and models.

    When using the fountain pump, there are several points that need special attention:

    1. Equipment grounding:

    In order to ensure the personal safety of fountain, the national compulsory standard for submersible pump is to adopt protective grounding. Otherwise, once the pump shell leaks, the water near the pump outlet and the water surface of the reservoir will be electrified, seriously endangering the safety of people and animals, and also causing the wave cost of electric energy.

    If the metal shell of the fountain pump is connected to the grounding body (the grounding resistance is not more than 4 Ω) meeting the national standard, when leakage occurs, the current will form a closed circuit through the working grounding wire and power supply of the pump shell, grounding body, grounding and transformer. Once the leakage current is too large, the protection device of the pump will work - fuse or air switch will trip, and the spray will be automatically disconnected Power supply of spring pump.

    2. Install leakage protector:

    Once the leakage crisis occurs, as long as the leakage value exceeds the action current value of the leakage protector, usually no more than 30mA, the leakage protector will work, disconnect the switch, and stop the fountain.

    3. Start up when the power supply voltage is abnormal:

    As a submersible pump, too high or too low voltage will make the pump body temperature rise, shorten the service life of the pump, or even burn out. Now in many places, there are problems such as long low-voltage power supply line, too high line start voltage and too low terminal voltage. Therefore, when the fountain is running, the operator should always pay attention to the power supply voltage value. When the power supply voltage value is higher than 10% or lower than 10% of the rated voltage, and the current is higher than 20% of the rated current, the operator should stop the machine immediately to avoid starting when the voltage is abnormal.

    4. Reverse rotation of motor:

    Although some fountain submersible pumps can produce water in both positive and negative directions, due to the small amount of reverse water and large current, the motor will be damaged if the reverse time is too long.

    5. Avoid long-term overload
