Operating principle

Pressure switch B1 (low water level)

This controls the water level in the upstream reservoir. The

contact closes on high pressure (high level)and opens on low

pressure (low level).

A relay KA1,with time delay on de-energisation, prevents the

pumps being stopped by turbulence (contact 58-57,see circuit

diagram below).

Pressure switches B2 nad B3

Set to different pressure values, these each control one level in

the downstream reservoir.Within their setting range, the contact

closes at low pressure (low leve) and opens at high pressure

(high level).

If the contact B2 is closed and contact B3 is open, only one pump

starts.

If both contacts B2 and B3 are closed, both pumps start. When

B3 reaches its set point (high pressure), its contact causes one

of the pumps to stop. When the liquid level in the reservoir is low,

and the two pumps must operate simultaneously, a time delay on

energisation relay KA2 delays the starting of the second pump :

sequence starting (contact 67-68 in the circuit diagram below).

Pressure switch B4

This controls the pressure in the surge suppressor and booster

reservoir. The booster pump is controlled manually (selector

switch S2)and prevents operation of the two pumps when in use

(contact 21-22 of KM3).

Selector switch S1

Gives priority to pump P1 or P2 in order to equalize their

operating times.

Often the water level in the reservoir is not at the lowest level and

a single pump would be started by the operation of pressure

switch B2.

Therefore, without the priority feature provided by the selector

switch, the same pump would be operated too frequently.

    操作原理

    壓力開關B1 (最低水位水平) 這控制水平面在在上游水庫。聯絡關閉在高壓(高level)and 打開在低壓(低水平)一個中轉KA1, 以時間延誤在de 加強, 防止泵浦由動盪被停止(聯絡58-57

    看電路圖如下)

    壓力開關B2 nad B3 被設置對不同的壓力價值, 這些各個控制一個水平在順流reservoir.Within 他們的設置範圍, 聯絡關閉以低壓(低leve) 並且打開在高壓(高水平)如果聯絡B2 是閉合的並且聯絡B3

    是開放, 只有一個泵浦起動

    壓力開關B4 這控制壓力在脈衝抑制器和助推器水庫。助推器泵浦手工被控制(選擇器開關S2)and 防止二個泵浦的操作當在使用中

    選擇器開關S1 制定優先權泵浦P1 或P2 為了調平他們的操作時間經常水平面在水庫不是在最低的水平並且一個唯一泵浦由壓力開關會發動B2 的操作所以, 沒有優先權特點由選擇器開關提供, 同樣泵浦太頻繁地會被管理

    如果你很確定自己很想結婚

    婚友社的確是一個有效率的管道

    年紀越大壓力越大

    以前我去婚友社時

    年輕的女生機會總是比較多

    時間總是不站在女生這邊的

    所以如果你想婚的念頭已經確定

    就去找一家評價好一點的婚友社!

    行動吧!

    這是我之前參加的婚友社我覺得不錯

    或搜尋"紅娘李姐"

    不過還是建議你自己去諮詢過看是否適合你!

    操作原理 壓力開關B1(低的水準面) 這在上游水庫裡控制水準面。  接觸差不多高壓的(高的水準) 並且在低上打開 壓力(低的水準) . 一接替KA1,有由de開出的時間延遲energisation,防止 抽湍流停止(接觸58-57,看電路 圖解在下面) . 壓力開關B2 nad B3 開始不同壓力價值,這些每控制一步 下游reservoir.Within他們確定的範圍,接觸 在低壓(低的leve)關閉  並且在高壓打開 (高的水準) . 接觸B2關閉和接觸B3是營業的如果,只有一台幫浦 開始。 接觸B2 和B3關閉如果,兩個抽開始。  什麼時候 B3到達它的給定值(高壓) ,它的接觸引起一 要停止的幫浦。  當液體水準在水庫裡是低的時, 並且這二台幫浦同時經營必須,時間延遲關於 energisation 繼電器KA2 延遲第2 台幫浦的開始︰ 順序起動(在電路圖裡與67-68聯繫在下面) . 壓力開關B4 這在浪涌抑制器和助推器裡控制壓力 水庫。  升壓幫浦是被手工控制的(選擇器 接通S2) 並且使用中時防止兩台幫浦的操作 (與KM3中的21-22聯繫) . 選擇開關S1 為了使他們的相等,優先幫浦P1或者P2 操作時間。 經常在水庫裡的水準面不在最低的水準和 壓力的操作將啟動一台單個的幫浦 接通B2。 因此,沒有由選擇者提供的優先權特徵 接通,相同的幫浦將被太經常操作
