摘要： A diaphragm pump mechanism is powered by steam generated by an internal heater coil heating the pumped water, which moves the diaphragm and an attached piston to pump water through the pump. The heater coil is turned on-and-off using a switch that is timed to the movement of the pump. The water is pumped through a series of one-way rubber valves and reed valves to prevent a back flow of water. The pressure generated by the steam is released when a reed valve located on the diaphragm makes contact with a pin located on the body of the pump, opening the reed valve and allowing the steam to travel through and to condense. The piston and diaphragm are returned to the starting position when the steam pressure is released by a spring attached to the pump shaft. On the return stroke an accumulator refills the diaphragm chamber with water.

摘要： The present disclosure relates to a pump mechanism driven by differential pressure conditions and method for delivery of materials. In one embodiment, the pump mechanism may be used to deliver treatment chemical to a plunger apparatus or directly to a wellbore by exploiting pressure conditions found at a well. In certain embodiments, the pump mechanism is able to balance high pressure conditions available within a petroleum formation against low pressure conditions present in a common flow line serving the well. In so balancing these pressures, the pump mechanism is able to automatically tune itself to the needs of the well, ensuring continued operation over a wider range of operating conditions. The pump mechanism has the further advantages of lower operation costs and less environmental impact as compared with existing pumps. The pump mechanism can be used in connection with a chemical applicator which can be used to apply chemical into, onto, or below, a plunger or plunger/dispenser apparatus used in plunger lift operations, or to apply chemical directly down the well. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要翻译： 本公开涉及由差压条件驱动的泵机构和用于输送材料的方法。 在一个实施例中，泵机构可以用于通过利用在井处发现的压力条件将治疗化学品递送到柱塞装置或直接传递到井筒。 在某些实施例中，泵机构能够平衡石油地层中可获得的高压条件与存在于为井工作的公共流动管线中的低压条件。 为了平衡这些压力，泵机构能够根据井的需要自动调整自身，从而确保在更宽范围的操作条件下持续运行。 与现有的泵相比，泵机构具有较低的操作成本和较小的环境影响的优点。 泵机构可以与化学施加器结合使用，该化学施加器可以用于将化学品施加到用于柱塞提升操作中的柱塞或柱塞/分配器装置中或之上，或者将化学品直接施加到井下。 要强调的是，该摘要被提供以符合要求摘要的规则，这将允许搜索者或其他读者快速确定技术公开的主题。 提交它的理解是，它不会用于解释或限制权利要求的范围或含义。

摘要： A multi-cylinder diesel engine provides split mode operation in which one or more cylinders function as air pumps. Compressed air supplied by the cylinders is amplified and stored to a high pressure air tank from which it may be used to run air brakes or other systems. Improved energy density is achieved over prior art vehicle air systems and an auxiliary air compressor is eliminated.

摘要： An automatic oil pump that includes a drive chamber having a reciprocal driving device and an oil chamber having a sucking device, located on two sides of a main body. The reciprocal driving device has a piston unit having a valve chamber at its center and a balance valve, pushed by a spring. The drive chamber has grooves on its inside wall. The piston unit has two channels, allowing air to flow into the valve chamber, passing two sides of the piston unit. On the piston unit is a driving rod, the driving rod penetrates into the main body and reaches into the oil chamber. A hermetic cover and a movable piston are attached to an end of the driving rod. On the wall of the piston unit are pluralities of through holes. The reciprocal driving device drives the piston in the oil chamber to move reciprocally, so oil is sucked into and out of the oil chamber continuously. Thereby, oil sucking speed and volume are upgraded to save time and labor, and oil pumping efficiency is enhanced.

摘要： A injection pump includes a needle valve which is disposed in the pump body cap. An air actuator valve is disposed in the pump piston head. The amount of air fed is controlled by the gap between the needle valve and a needle valve seat which is also located in the pump body cap. At the end of the pumping stroke, a spring on the air actuator valve contacts the bottom surface of the body cylinder chamber to cause the air actuator valve to open and release the trapped air from the body cylinder chamber through the air actuator valve so that the air can exit the pump. This action allows the spring around the piston and plunger to release and return the piston and plunger to the starting position.
