摘要： The invention provides a spiral flow constant pressure pump, comprising a pump body, a pump casing and an impeller; the pressure drop between the end face of pump rear cover and the rear end face of impeller auxiliary blade is used for providing wash water to sealing device; a hole is opened in the high pressure area of the end face of pump rear cover; the position of the hole for entering the seal cavity is close to the sealing device, leading expectant high pressure water into the seal cavity; a hole is opened in the low pressure area of the end face of pump rear cover; the position of the hole for exiting the seal cavity is far away from the sealing device; the expectant high pressure water that enters the seal cavity will flow back to low pressure area through the drainage hole along flow direction after washing the sealing device; the pump recycles a part of energy, improves the hydraulic efficiency, decreases the turbulent loss and takes way the gas might exist in the seal cavity; the extended orifice sleeve reduces the damage to the pressure drop of the auxiliary blade caused by the high pressure water leaked from seal cavity and thus ensures the balance effect of the auxiliary blade.

摘要： The present invention is a pump used for applications where a solid is present in wastewater and other liquids that requires cutting and reduction in size so as to pass the solid through the inlet to the outlet of the pump. The pump has a pump casing with an inlet and an outlet formed therein. A drive unit rotates a drive shaft extending axially through the pump casing to an impeller and a cutter bar. The pump is further configured with a radial cutter ring assembly positioned adjacent the cutter bar and the inlet providing a shredding cutting action of solids between the rotating cutter bar sliding past a radial cutter ring assembly held stationary, e.g. cutting blades formed in an edge of the cutter bar rotate across an internal surface of the radial cutter ring assembly. The pump also has an axial cutter ring assembly with one or more blades forming openings adapted for the passage of solids from the inlet to the outlet to provide a shearing cutting action of solids by a rotation of an upper surface of the cutter bar sliding past an axial cutting surface of the blades of the axial cutter ring assembly. The shred and shear pump may be configured with a plurality of slots on the internal surface of the radial cutter ring assembly to hold woven fibrous material for the shredding cutting action. The pump also features improved optimized flow, cutting and reducing solids in the form of woven fibrous materials, and adjustability of the cutter housing for precision and wear adjustment.

摘要： A pump impeller (10) adapted for rotatable mounting within a volute (12) of the centrifugal slurry pump (14) comprises an intake opening (16) formed coaxially with an axis of rotation (18) of the impeller (10). The impeller (10) also includes an outlet opening (20) extending about the periphery of the impeller (10) and a plurality of blades (22) extending generally radially between the intake opening (16) and outlet opening (20). The region between adjacent blades (22) defines a respective blade passage (24) through which slurry flows upon rotation of the impeller (10). The impeller (10) is dimensioned relative to the volute (12) so that the ratio of the blade passage width b1 at the entry of the blade passage (24) to the blade width passage b2 at the periphery of the impeller (10) is in the range of 1.5 to 1.7, and the ratio of the diameter D2 of the impeller (10) to the blade passage width b2 is in the range of 9.3 to 10.2 and that the ratio of the impeller diameter D2 to the width of the volute b3 is in the range of 3.8 to 4.2. This enables the pump to operate in a specific speed range of 22 to 30.

摘要： The invention relates to a hydrodynamic machine, in particular a hydrodynamic retarder, comprising a bladed impeller and a bladed turbine which together form a toroidal working chamber that can be filled with a working fluid in order to produce a hydrodynamic circuit flow for transmitting a drive torque, at least the bladed impeller or at least the bladed turbine being driven by a drive shaft of the hydrodynamic machine via an axis of rotation. The hydrodynamic machine also comprises a side-channel pump having a pump impeller with a plurality of pump blades and a channel running in the circumferential direction of the pump impeller, said channel having an inlet end and an outlet end. The pump blades are arranged in the channel or opposite the channel such that when the pump impeller rotates, a conveying effect is created in the channel in such a way that a suction effect is produced at the inlet end and a pressure effect is produced at the outlet end. The inlet end or the outlet end form a conductive connection for the working fluid with the working chamber. The hydrodynamic machine according to the invention is characterised in that the pump impeller is supported radially on the drive shaft in a rotationally fixed manner such that it can be moved axially and/or tilted at an angle.
