摘要： A float operated pneumatic pump which separates water from hydrocarbons within a well at the pump in accordance with the density or specific gravity of the water and hydrocarbon fluid. The pump includes a displaceable fluid inlet for allowing fluid to enter the pump which generally tracks the level of the water/hydrocarbon interface. The pump includes an outer tube forming an outer chamber and an inner or dip tube placed within the outer chamber of the outer tube and forming an inner chamber. A well float includes the fluid inlet and has a density which enable the float to remain in proximity to the water/hydrocarbon interface. A tubular coil or conduit provides fluid passage between the fluid inlet and the outer chamber. Also, a fluid separator is located at the bottom end of the outer tube and defines a fluid passage between the inner and outer chambers. In one configuration, the separator allows water to exit the pump from the outer chamber while the hydrocarbons remain within the outer chamber. In a second configuration, the separator prevents water from entering the pump and enables hydrocarbons to be discharged from the pump. In an alternative embodiment a single piece intake manifold is used which has a fixed fluid inlet. This permits the overall pump to be made significantly less in length to permit the pumping of shallower amounts of fluids from within a well.
摘要翻译： 一种浮动操作的气动泵，其根据水和烃流体的密度或比重将泵与泵内的井中的烃分离。 泵包括可移动流体入口，用于允许流体进入泵，其通常跟踪水/烃界面的水平。 泵包括形成外室的外管和放置在外管的外室内部并形成内室的内管或汲取管。 浮子包括流体入口，并且具有使浮子保持靠近水/烃界面的密度。 管状线圈或导管在流体入口和外室之间提供流体通道。 此外，流体分离器位于外管的底端，并且在内室和外室之间限定流体通道。 在一种构造中，分离器允许水从外室离开泵，而烃保留在外室内。 在第二种构造中，分离器防止水进入泵并使烃从泵排出。 在替代实施例中，使用具有固定流体入口的单件进气歧管。 这允许整体泵的长度明显更小，以允许从井内泵送较浅量的流体。

摘要： There is provided a flow-through cell with a diverter valve for continuously monitoring specific parameters of a fluid which passes through the flow-through cell. The diverter valve diverts a portion of fluid flow from a fluid line to the flow-through cell. The flow-through cell has an analyzing probe capable of monitoring a plurality of conditions of the fluid that is flow through the cell. By continuously monitoring specific parameters of the fluid as it moves through the flow-through cell, it is possible to constantly monitor the condition of the fluid and react to changes or stabilization of the readings provided by the probe.

摘要： There is provided a fluid sampling apparatus for withdrawing samples of groundwater or other fluids from a well or other monitoring site. The apparatus preferably includes pump means, packer means, conduit means and a wellhead assembly that are permanently installed at the well or monitoring site and are thereby dedicated thereto in order to avoid or minimize cross-contamination of samples from site to site. The packer is integral with the pump and isolates the groundwater below the packer in order to minimize the amount of groundwater which must be pumped in order to purge the well prior to taking an acceptable sample. The apparatus preferably also includes a removable and portable controller means adapted for easy and convenient transportation and connection to such dedicated fluid sampling components at various wells or monitoring sites.

摘要： A float operated pneumatic pump has an outer pump body forming an outer chamber and a dip tube forming an inner chamber therein. The inner chamber of the dip tube is in communication with the outer chamber of the pump body through a back flow discharge check valve. An inlet is located at a first end of the outer pump body for permitting liquids to enter both the inner and outer chambers. A discharge housing is located at a second end of the tubes and contains a liquid discharge port in communication with the second end of the dip tube. An air inlet port is located in the discharge housing for permitting pressurized air to enter the second end of the outer pump body. An air exhaust port is provided for permitting air in the outlet chamber to escape to atmosphere when fluid is entering the inner and outer chambers. A float is disposed on the outside of the dip tube within the outer chamber of the pump body. The float provides buoyancy to actuate the pump and provides weight to de-activate the pump. An inlet valve is disposed within the air inlet port for selectively admitting in a discharge mode, and blocking in a refill mode the source of compressed air into the outer chamber of the pump body. An exhaust valve is disposed within the air exhaust port for selectively venting in the refill mode and blocking in the discharge mode the outer chamber to the air discharge port. An actuator linkage, or a lost motion device, is coupled between the float and an off center pivot lever. The off center pivot lever actuates both the inlet and exhaust valves with the off center feature of the pivot lever increasing the force of the buoyant float. The float operated fluid pump further includes first and second attracting magnets, the first magnet being located on the movable end of the off center pivot lever and the second magnet being located within the discharge housing. The first and second magnets come together by movement of the float and operate to keep the pumping system in the discharge mode until the weight of the float separates the magnets and moves the pumping system into the refill mode.

摘要： A counting apparatus which is designed to be placed in parallel to a fluid flow line has a differential pressure switch which is placed across an orifice positioned within the fluid flow line. A counting mechanism is associated with the differential pressure switch to register a count when signaled by the differential pressure switch. The differential pressure switch is operable to react to the difference in pressure across the orifice to signal the counter to register a count. The orifice can be a fixed or a variable orifice. In another embodiment of the invention, a fixed or variable orifice is placed within the diaphragm of a diaphragm type differential pressure switch to adapt the differential pressure switch to be placed in series with the fluid flow line rather than in parallel to it.

摘要： A float operated, top fill, recovery unit floats in a body of contaminated groundwater to recover a layer of liquid hydrocarbons residing on top of the groundwater. The recovery unit has an upper end fitted with a discharge check valve assembly and a lower end that is closed, the discharge valve assembly including a semi-permeable screen which is positioned in and skims the liquid hydrocarbons, and a series of passages and check valves for directing the hydrocarbons via a return line to a holding tank. In an embodiment disclosed, the lower end of the unit is formed in part by an inlet check valve arrangement which has had its check ball removed such that the arrangement does not operate to inhibit flow, and a closure plate is secured to the inlet valve arrangement to prevent external fluid from entering the unit. Sinking of the recovery unit allows hydrocarbons to pass through the screen to fill the interior of the unit so that it can be pumped out of the unit by compressed air and conveyed to the holding tank. The top fill recovery unit is easily modified to a bottom fill underground contaminated water recovery unit by removing the closure plate and replacing the check ball in the inlet valve arrangement, removing the top discharge valve assembly, and connecting the return line directly to the top of the unit.

摘要： There is provided a counting apparatus which is designed to be located in any position in series with a fluid flow line. The apparatus has a first magnet in an air chamber of the body of the counter. As the fluid passes through the air chamber, the first magnet is forced down the air chamber by the fluid flow. The magnetic field of the first magnet passes through a magnetic field of a second magnet located in the mechanical counter causing the counter to mechanically change the number. When the fluid flow is stopped, a spring returns the first magnet to its original position again passing by the second magnet in the counter allowing the counter to reset for the counting of the next cycle.
