摘要： The invention relates to a dense phase powder pump and a method for operating a dense phase powder pump in a powder-conveying mode. In order, in a simple manner, to prevent or at least reduce powder accumulations and clogging with powder, in particular on the powder inlet side of the powder conveying chamber of the dense phase powder pump, and thus in the region of the powder inlet valves, according to the invention, during a predefined or specified time period in at least one output phase and preferably at the end time of the output phase of a powder cycle, at least one of the following conditions exists: i) the powder inlet valve of the dense phase powder pump is open; ii) the powder outlet valve of the dense phase powder pump is closed; and/or iii) the application of an overpressure to the powder conveying chamber of the dense phase powder pump is interrupted.

摘要： The invention relates to a dense-phase powder pump for conveying coating powder from a first powder reservoir to a second downstream powder reservoir or to a downstream powder spray-coating gun or similar device for spraying coating powder. The dense-phase powder pump has at least one powder conveying chamber, which is/can be fluidically connected to the first powder reservoir via a powder inlet, and to the second powder reservoir or to the powder spray-coating gun or similar device for spraying coating powder via a powder outlet. At least one powder inlet valve is provided at the powder inlet and at least one powder outlet valve is provided at the powder outlet. According to the invention, in order to make the dense-phase powder pump less prone to require maintenance during operation and, in particular, to constantly guarantee a continuous and uniform conveying of the powder, regardless of the type of powder, the at least one powder inlet valve and/or the at least one powder outlet valve has/have an effective flow cross-section in the respective open state, which corresponds to at least 35% of the effective flow cross-section of the at least one powder conveying chamber.

摘要： A powder feeding device, in particular for coating powder, is disclosed. The powder feeding device includes a dense phase powder pump which has at least one conveying chamber with a powder inlet valve and a powder outlet valve. Furthermore, a control device is provided for selectively operating the dense phase powder pump in a powder conveying more or a flushing operating mode. The powder inlet valve and the powder outlet valve of the dense phase powder pump are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. The control device is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve and/or powder outlet valve depending on the respective operating mode of the dense phase powder pump and/or depending on a pressure which prevails in the conveying chamber.

摘要： A powder conveyor has a pneumatically actuated dense phase powder pump and a pressure controller. The dense phase powder pump comprises at least one conveyor chamber having a powder inlet valve and a powder outlet valve. The pressure controller can be used to adjust and maintain a set pressure on the at least one conveyor chamber of the dense phase powder pump that is or can be previously defined and/or to adjust and maintain an actuation pressure on the powder inlet valve or the powder outlet valve that is or can be previously defined. The powder conveyor further comprises a gas flow detection device for detecting or determining a quantity of gas that is fed or removed per time unit when the set pressure is adjusted and maintained on the at least one conveyor chamber or a quantity of gas that is fed to the powder inlet valve or the powder outlet valve per time unit when the actuation pressure is adjusted and maintained. An evaluation device compares at least one detected or determined gas flow value with a corresponding set value and automatically generates an error and/or alarm signal when a deviation is detected.
