摘要： Feed devices for liquid samples serve to convey liquid samples, for example to convey a liquid sample from waste water in a waste water treatment plant so as to monitor the treatment process. Known feed devices feed continuously at relatively low speeds. Films may accrete in the feed line that hinder the feeding and may react with the liquid sample. Therefore, the feed line must be cleaned frequently. In view of this, it is the object of the invention to improve the handling and the maintenance of a feed device for liquid samples. According to the invention, this object is solved by the fact that the feed pump (16) feeds in a pulse-like manner and the feed pump (16) as well as the feed line (18) are configured such that the expansion volume of the feed line (18) during the feed pulse is at most 50% of the pulse volume. Thereby, the feed line is cleaned and kept free of accretions.
摘要翻译：用于液体样品的进料装置用于输送液体样品，例如从废水处理厂中的废水中输送液体样品，以监测处理过程。已知的进料装置以相对低的速度连续进料。进料管线中的膜可能会渗入，阻碍进料，并可能与液体样品发生反应。因此，必须经常清洁送料线。鉴于此，本发明的目的是改进用于液体样品的进料装置的处理和维护。根据本发明，该目的通过以下事实来解决：馈送泵（16）以类似脉冲的方式进给，并且进料泵（16）以及进料管线（18）被构造成使得膨胀体积进料脉冲期间的进料管线（18）至多为脉冲体积的50％。因此，进料管线被清洁并保持不受压力。

摘要： A diaphragm failure monitoring system for detecting leakage in a diaphragm of a diaphragm pump. The system includes a pump having an operating chamber containing a working fluid and a pumping chamber for pumping material into and out of the pump and a diaphragm separating the operating and pumping chambers. A first optic fiber is joined to the operating chamber for transmitting an optic signal across the working fluid. A second optic fiber is joined to the operating chamber for receiving the optic signal from the first optic fiber. An electric signal establishing device establishes a first electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through uncontaminated working fluid. The electric signal establishing device establishes a second electrical signal when the optic signal from the first optic fiber to the second optic fiber passes through contaminated working fluid, whereby leakage of a contaminating material through the diaphragm into the operating chamber can be detected when the second electrical signal is established.

摘要： A pump control system which can distinguish between water and oil so that a pump can be controlled to pump water and deactivated before oil is pumped. Sensing is accomplished by a pair of capacitive sensors, one located above the other in a vessel in which water accumulates. A dual mode frequency oscillator is associated with each sensor. Each sensor reacts to the dielectric constant of the liquid at the sensor by changing its capacitance, to thus detect the presence of a conductive substance, such as a liquid, to cause the sensor's oscillator to switch its mode of oscillation. The dual mode oscillator of each sensor selectively generates a control signal having two different duty cycles. As the dielectric constant of the liquid medium is sensed, a logic circuit interposed between the sensors allows the output of each sensor to be turned off when only the lower sensor is in water. The circuit turns on the pump only when both sensors are in water and the pump remains on until both sensors are out of water. An adjustable deadband is provided, thereby avoiding having the pump turning on and off with a slight water level change. Each sensor detects the difference between dielectric constants of air and of oil, in relation to that of water. As a result, the pump control system differentiates between water and oil and activates the system to pump water while deactivating the system before oil on the water surface is pumped.
摘要翻译：一个泵控制系统，可以区分水和油，以便在油被泵送之前可以控制泵来泵送水并停用。感应通过一对电容传感器实现，一对电容式传感器位于水分积聚的容器中。双模频率振荡器与每个传感器相关联。每个传感器通过改变传感器的电容对传感器液体的介电常数进行反应，从而检测出诸如液体的导电物质的存在，从而使传感器的振荡器转换其振荡方式。每个传感器的双模式振荡器选择性地产生具有两个不同占空比的控制信号。当感测到液体介质的介电常数时，插入传感器之间的逻辑电路允许当只有下传感器处于水中时才关闭每个传感器的输出。只有当两个传感器都在水中时，电路才会打开泵，并且泵保持打开，直到两个传感器都不在水中。提供了一个可调节的死区，从而避免了在轻微的水位变化时使泵打开和关闭。每个传感器检测空气和油的介电常数与水的介电常数之间的差异。因此，泵控制系统在水和油之间有区别，并在泵送水面上的油之前使系统启动，同时停用系统。
