摘要： A metering pump comprises a pump chamber with a diaphragm for delivering a metering agent to a metering point. The pump chamber is adapted to be connected with the metering agent tank through a suction conduit comprising a suction valve. Moreover, a return conduit comprising a head valve is provided.For providing an automatic bleeding or ventilation of the metering pump and the possibility of using the pump also for metering aggressive media, the outlet of the pump chamber is adapted to be connected with the metering point through a second head valve. The outlet is connected with the return conduit and a bleed valve is provided in the return conduit.

摘要： A plunger of a plunger pump is formed with an air vent passageway having its one end open to a compression chamber and the other end adapted to communicate with a reservoir space open to the atmosphere when the plunger comes near its top dead point. Air or gas trapped in the liquid sucked into the compression chamber will flow into the air vent passageway so as to be discharged into the reservoir space when the passageway gets into communication with it. Since air or gas is removed from the compression chamber, the pumping efficiency is prevented from decreasing.

摘要： Connected to the suction pipe leading to a pump inlet is an air eliminator comprising a valve housing defining a chamber and having a first valve seat through which the suction pipe communicates with the chamber and a second valve seat through which the chamber communicates with atmosphere, the chamber increasing in cross-sectional area from the first seat toward the second seat. A ball valve is normally seated on the first seat to prevent air from entering the suction pipe but is displaceable to allow discharge of air under pressure from the suction pipe through the second seat while suspended by the force of the discharging air. The ball valve has a specific gravity less than the liquid, whereby liquid entering the chamber from the suction pipe floats the ball valve against the second seat to block the discharge of liquid.
摘要翻译：连接到通向泵入口的吸入管是空气消除器，其包括限定腔室的阀壳体，并且具有第一阀座，吸入管通过该第一阀座与腔室连通;第二阀座，腔室与大气连通，室从第一座椅朝向第二座椅的横截面积增加。球阀通常位于第一座椅上，以防止空气进入吸入管，但可以移动，以允许通过排出空气的力悬浮，通过第二阀座从吸入管排出空气。球阀的比重小于液体，由此从吸入管进入腔室的液体将球阀浮在第二座上以阻止液体的排出。

摘要： Spray unit includes a diaphragm pump mechanically driven by a vibrator-armature through a force multiplier to facilitate pumping of fluids including both latex and oil base paints. A flexible backup member is provided for the diaphragm which acts as a hydraulic cushion to eliminate any high stress areas against the diaphragm and provides a secondary seal preventing the pumping fluid from contaminating the various parts of the device in the event of failure of the diaphragm.

摘要： This specification discloses a pumping system with circulating mechanism of bubble and gas in which the pump room at its upper portion is provided with a check valve which at its upper end is connected to a guide sleeve which at its upper end is coupled through a valve with a conduit connected to an upper portion of the pump pipe provided at its lower end with an outlet valve so that a divided flow which is sufficiently small as not to draw up the slurry is formed.

摘要： This invention relates to an automatically controlled vent valve in a vent line connected to the suction line in a cryogenic pumping system. The vent valve is in an open position during the cooldown cycle and is moved to a closed position after the system has reached desired operating conditions. Blowby gas which leaks around the piston of the pumping system provides the pressure for closing the vent valve. The vent valve contains an orifice through which the blowby gas bleeds and returns to the storage vessel for the cryogenic fluid being pumped.
