摘要： A high pressure plunger pump, having at least one plunger arrangement which comprises a working space connected to a valve seat suction line and a valve seat pressure line, in which a plunger is arranged in an axially reciprocable manner, wherein the valve seat pressure line is closeable by a pressure valve and the valve seat suction line by a suction valve, and the suction valve can be kept in an open position in a controlled manner as required by means of a counter-pressure device, is designed so that the counter-pressure device has a supply line via which a control fluid can be guided to the suction valve for keeping the suction valve open, wherein a low-pressure pump is connected to the supply line for generating pressure of the control fluid.

摘要： The present invention is a sludge pump system which includes a means for monitoring operation of a sludge pump. The sludge pump includes a material cylinder and a piston moveable in the material cylinder. A pump drive moves the piston during working cycles which include a pumping stroke and a filling stroke. A pump valve mechanism connects the material cylinder to an outlet during pumping strokes and connects the material cylinder to an inlet during filling strokes. A means for monitoring operation of the pump is provided. The means for monitoring includes a means for sensing a first parameter related to operation of the pump drive, a means for sensing a second parameter indicative of operation of the piston, and a means for determining errors in the operation of the pump based upon the first parameter and the second parameter.

摘要： A system and method for controlling operation of a sludge material handling system is disclosed. The sludge material handling system includes a positive displacement piston/cylinder pump, a sludge material feed system which delivers sludge material to the pump, and a sludge material disposal system which receives and disposes of sludge material from the pump. A first parameter is sensed, the first parameter bearing a known relationship to an actual volume of sludge material delivered during a pumping cycle. An output value is determined from the first parameter. A control signal is provided as a function of the output value.

摘要： A system for the transport of high solids sludge includes a positive displacement pump for pumping sludge through a pipeline. The volume of sludge transported is accurately measured by determining the fill percentage by using a material flow signal, measured time intervals, hydraulic fluid pressure, or hydraulic fluid flow rate during each pumping cycle.
