The inner surface of the inner wall defines a cavity for insertion and mounting of a grinder pump therein. In addition to the substantially cylindrical inner wall, there is a substantially cylindrical outer wall having an inner surface and outer surface, wherein the outer wall has a diameter greater than the inner wall. For increasing the structural integrity of the grinder pump station, a plurality of rigid members extend between the substantially cylindrical inner wall and the substantially cylindrical outer wall, each of the plurality of rigid members being affixed to the inner wall and each of the plurality of rigid members being engaged to the inner surface of the outer wall. A base disposed is located adjacent to a lower portion of the inner and outer walls. The grinder pump station may include a plurality of rigid members that define a central corrugated wall. The central corrugated wall may further comprise a plurality of alternating crests and troughs, wherein each of the crests are engaged to the inner surface of the outer wall and each of the troughs are affixed to the outer surface of the inner wall.

摘要： A system and process for fluid jet cutting of a workpiece providing for self orientation of a catcher vessel. This invention comprises a cutting head adapted to be connected to the robot arm of a robotically controlled cutting system. A nozzle is mounted in the cutting head and adapted to dispense a jet cutting fluid stream along a cutting axis to be directed against a workpiece. The system further comprises a catcher assembly including a bracket supporting a catcher vessel having a receiving aperture. The catcher vessel contains a sacrificial material for dissipation of kinetic energy of the spent jet cutting stream. The supporting bracket includes an arm which depends from the cutting head along a traverse which is laterally offset from the cutting axis. The catcher vessel is oriented so that the receiving aperture is aligned with the cutting axis of the nozzle so that the spent cutting stream emanating from the nozzle and passing through the workpiece ultimately passes into the aperture of the cutting vessel. The catcher assembly is rotatably mounted on the cutting head for rotation about an axis coincident with the cutting axis along which the fluid stream is directed. This allows the bracket and the catcher vessel to rotate relative to the nozzle while retaining the aligned orientation of the catcher vessel aperture with the cutting axis. Thus, the catcher vessel is maintained in a mechanically self oriented configuration relative to the nozzle throughout the cutting operation.

摘要： An automated tool positioning system is disclosed. The system includes a plurality of work stations, each having a set of guide rails disposed along the length thereof. A single control device is provided and includes a set of guide rails adapted to be temporarily aligned with the guide rails of each work station. The control device is thus movable from work station to work station and operates with a novel tool support member which may be selectively positioned along any guide rail to support a cutting tool at a selected position on a particular work station. The tool support member includes arcuate bearing surfaces which permit the cutting tool to be rotated through a conical section having its vertex at the cutting point of the tool in response to the output of a workpiece surface detection circuit. In this manner, the cutting tool may be automatically and accurately positioned normal to the contoured surface of the workpiece.

摘要： A grinder pump includes a pump assembly, a grinder mechanism, and a motor disposed between the grinder mechanism and the pump assembly. A shaft of the motor is operably attached at one end thereof to the grinder mechanism and at the other end thereof to the pump assembly. This arrangement enables providing smaller radial clearances between the cutting portions of the grinder mechanism. Vortex-type impeller vanes can be associated with a grinding head of the grinder mechanism to assist flow of effluent from the grinder mechanism to the pump assembly via a passageway extending about, and/or in parallel with, a motor mounting unit.

摘要： A grinder pump station capable of having its height adjusted in the field during installation has a longitudinal tank having a substantially cylindrical non-corrugated inner wall secured to a substantially cylindrical corrugated outer wall, a separate transition section for mounting a grinder pump unit within the longitudinal tank, a removable lid assembly attached to the top of the longitudinal tank, and a base attached to the bottom of the tank. A grinder pump unit may be mounted inside of the tank. The removable lid assembly includes an electrical and ventilation interface for the grinder pump unit mounted in the tank, thereby facilitating adjustment of the height of the tank through variation in its longitudinal extent without interference with the electrical and ventilation interface. The transition section separates an upper tank portion from a lower tank portion, preferably has a non-corrugated side wall, and includes a sewage inlet opening and a sewage outlet opening through its side wall.
