An abrasive slurry delivery system configured to discharge a high pressure mixture of water (30) and abrasives (54, 54′) for further admixture with a flow of high pressure water (30) to generate an abrasive slurry and ultimately an abrasive slurry jet is provided. The delivery system includes a storage chamber (56), a discharge chamber (58) and a shuttle chamber (60) positioned therebetween. The shuttle chamber (60) is configured to intermittently receive abrasives (54) from the storage chamber (56) and intermittently supply the abrasives (54, 54′) mixed with high pressure water (30) to the discharge chamber (58) to be selectively discharged therefrom. High pressure abrasive slurry cutting systems and related methods are also provided.

The present disclosure relates to a soot blower including: a lance tube which includes one end that reciprocally moves in one direction on a surface of an inlet port of a flow path of the tubular heat exchanger; a drive unit which is connected to the lance tube and reciprocally moves and rotates the lance tube in the one direction; a first nozzle which is connected to the one end of the lance tube and discharges steam to the inlet port; and a second nozzle which is disposed adjacent to the first nozzle and connected to the one end of the lance tube and discharges solid particles to the inlet port, and the present disclosure relates to a method of cleaning a tubular heat exchanger by using the soot blower.

The invention relates to a device for the erosive processing and/or the cleaning of a material or of a material surface by means of at least one high-pressure fluid jet, comprising a nozzle (1) for outputting a high-pressure fluid jet and an apparatus (2) arranged upstream of the nozzle (1) for producing a pulsed high-pressure fluid jet, wherein the apparatus (2) comprises at least one valve (3). According to the invention, the valve (3) is designed as a servo valve and has an axially movable valve piston (4) for connecting a valve feed (5) to a valve outlet (6) such that the flow through the valve (3) can be specified by means of the axial position of the valve piston (4). The invention further relates to a method for operating a device according to the invention.

A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.
