一, 概述
UQK-65-C系列船用浮球液位控制器(以下简称控制器)。它山浮球,连杆,铁心部分和磁性开关发生转换机构组成,由浮球检测到的液位变化直接传给磁性开关转换机构。控制器合理地选用全密封引磁隔离开关转换机构,使永磁元件不能直接接触介质,避免了介质内部的混杂蚀质引起轧熬和卡死现象,也不因机构的摩擦而发生故障。
控制器还符合国际电工委会(IEC)92-504(1974年)船用电器设备器特殊要求-控制和测量仪表,人民共和国船舶检验局(1983)钢质海船入级与建造规范有关规定,部分还符号英国劳氏船级社的控制和电器设备的形式认可实验规则(1975年)。
二, 用途
UQK-65-C系列位控制器广泛适用于海洋船舶及其它设备的机舱副机锅炉等装置的润滑油,燃油,废油,淡水,污水等密闭或开口容器内的液位报警和控制的作用。但不适宜于对不锈钢材料起腐蚀作用和易燃,易爆的流体的危险场所。

1. 控制作用;单点位式
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,即浮球在液体里受到向上的浮力,浮力的大小等于浮球所排开液体的重量。随着容器内液位的变化,浮球随之上下运动,从而带动连杆,铁心上下移动,使铁心与磁钢的相对位置发生变化。通过铁心与磁钢相互磁力的作用磁钢微动开关转换机构翻转,使微动开关动作,切换差约10-40或10-70mm如图-所示。该微动开关可来操作报警器,阀门或控制其他装置。

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 10-40mm of 10-70mm shown in fig,The miniature seitch will send a signal to realize level alarm,to operate the valve,to control other equipment.
