一, 概述
UQK-65-C系列船用浮球液位控制器(以下簡稱控制器)。它山浮球,連桿,鐵心部分和磁性開關發生轉換機構組成,由浮球檢測到的液位變化直接傳給磁性開關轉換機構。控制器合理地選用全密封引磁隔離開關轉換機構,使永磁元件不能直接接觸介質,避免了介質內部的混雜蝕質引起軋熬和卡死現象,也不因機構的摩擦而發生故障。
控制器還符合國際電工委會(IEC)92-504(1974年)船用電器設備器特殊要求-控制和測量儀表,中華人民共和國船舶檢驗局(1983)鋼質海船入級與建造規范有關規定,部分還符號英國勞氏船級社的控制和電器設備的形式認可實驗規則(1975年)。
二, 用途
UQK-65-C系列位控制器廣泛適用于海洋船舶及其它設備的機艙副機鍋爐等裝置的潤滑油,燃油,廢油,淡水,污水等密閉或開口容器內的液位報警和控制的作用。但不適宜于對不銹鋼材料起腐蝕作用和易燃,易爆的流體的危險場所。
三, 主要技術參數
1. 控制作用;單點位式
Ⅰ,BRIEF
Marine Floating Ball Liquid Level Controlleru (called controller in following),is made up of the floating ball the connccting rod,iron core party and the maghetic switching mechanism The Liquid Level change checked by the floating ball will be dircctiy sent to the magnetic switching mechanism The controller resonably selects sealing magnetic isolated on-off switching mechanism in order that the permnnent-magnet component donit dircctly contact the agent So there aren’t both rolling stop and stoping machine by the mixed impurity of the internal agent and to occur the stoppage for the mechanical frictiou of the mcchanism
The controller also meets the special requirment of marine control and mcasurement instruments provided by IEC 92-504(1974)of the Intenational Elcctical Industrial committee and is up to the Steel Structure Ocean Ship Classification and the relative stipulations on the marine measurement instrument of Marine Inspection Bureau of the People’sRepublic of China,and is partally up to the test rules on control and electric equipment for model acceptance of Lioyd’s Register of Shipping
Ⅱ,APPLICATION
Marine Floating Ball Level Controllcr series UQK-65-C,iswidciy used in Ocean Ships and various closevessele and openvessels for liquid level alarm of control in other equipment for lubicating-oil,kerosene of waste oil fresh water,industial waste water ctc in auxiliary machine boiler in engine room of a ship But the controller is not suitable for the agent corrosive to stainless and in the explosive and inflammable dangerous sites

控制器工作原理基于阿基米德定律,即浮球在液體里受到向上的浮力,浮力的大小等于浮球所排開液體的重量。隨著容器內液位的變化,浮球隨之上下運動,從而帶動連桿,鐵心上下移動,使鐵心與磁鋼的相對位置發生變化。通過鐵心與磁鋼相互磁力的作用磁鋼微動開關轉換機構翻轉,使微動開關動作,切換差約10-40或10-70mm如圖-所示。該微動開關可來操作bjq,閥門或控制其他裝置。

Ⅳ,WORKING PRINCIPLE
The controller’s working principle is based on the Archimedes’principle,I,e the floating ball immersed in the liquid a upward floatage which is equal to the liquid weight drained off by the fioating ball,With the variation of the liquid level in the vessels,the floating ball will go up anddown and drive the connecting rod and the iron core to move upwards and downards,andmake the relative position to chang between the ieon core and the magntic steel,The funcion of magnetic between iron core and the magentic steel makes the minatre on-off switching mechanism turn over and makes the switch act,the changing over difference about 10-40mmof 10-70mmshown in fig,The miniature seitch will send a signal to realize level alarm,to operate the valve,to control other equipment.

Ⅶ.ERECTION AND USAGE
1. Before mounting the controller,the controller should be examind in order to make sure that there is ont any fricion of screw-loosing.
2. The controller should be mounted in the position where it is easy to observe and con-venient for maintenance,And the verticality of the connecting fod centreline should be main-tained.
3. The frequency and the amplitude of the level fluctuation of the agent measured shouldn’t be too much.
4. When the viscosity of the agent measure is rather high of when the agent is easy to becrystallized,the controller is not available.
5. The controller is not suitable for the agent corrosive to stainless steel and in the ex-plosive and inflammable dangerous sites.
Ⅷ.ORDER GUIDE
1. When you place an order,please specify the type,the name,the measure scope,the pressure,the temperature and the specifv gravity of agent.
2. If you have a special requirement,we will accord with the order’s agreement.
