There is provided a system that includes (a) a power feed that distributes a high DC voltage in a building, where the high DC voltage is in a range of about 300 to 600 VDC, (b) a converter, coupled to the power feed, that receives the high DC voltage, and scales the high DC voltage to a low DC voltage, and (c) a controller that controls a firing rate of the converter so that the low DC voltage is in a range of about 23 to 48 VDC.

The dispenser comprises a hopper (1) to contain the loose product (P), and an screw feeder (7) to feed the loose product from the hopper towards a dispensing opening (25). Positioned in the dispensing opening is a shut-off valve (27), which closes the dispensing opening. The screw feeder feeds the loose product towards the valve and movement of the valve causes delivery of the loose product from the cells.

A measuring apparatus (1) for concrete materials, comprising an aggregate hopper (3) as aggregate feed means for feeding fine aggregate (2) as aggregate, a water supply pipe (4) as water supply means, an aggregate measuring bin (51) for storing and measuring the fine aggregate (2) supplied from the aggregate hopper (3), a measuring tank (5) for storing the fine aggregate (2) supplied from the aggregate hopper (3) as water-immersed aggregate together with water supplied through the water supply pipe (4), a load cell (6) as water-immersed aggregate mass measuring means for measuring the mass of the water-immersed aggregate in the measuring tank, an electrode sensor (7) as water level measuring means for measuring the water level of the water-immersed aggregate in the measuring tank (5), and a water level holding device (8) as water level holding means for holding the water level of the water-immersed aggregate in the measuring tank (5) at a desired water level.

The invention relates to the technical field of motor manufacturing, in particular to a high-performance motor iron core processing equipment and processing method. The processing equipment includes a coiling device, a leveling device, a coating thickness measuring device and a stamping device. In the processing equipment provided by the present invention, the steel strip coiled on the coiling device can be released automatically by its own tension and elasticity, and the steel strip after being released is leveled by the leveling device to become smoother, which is beneficial to subsequent processing. The coating thickness measuring device can coat the upper and lower surfaces of the steel strip with paint and can detect the thickness of the steel strip and the thickness of the paint on the steel strip, and can squeeze out excess paint and water on the steel strip. The stamping device can stamp the steel strip into steel sheets of a certain size, heat and solidify the steel sheets, and automatically stack and transport the steel sheets. The entire processing equipment can run automatically, with high processing efficiency, no need for manual labor, which can save labor costs, facilitate the realization of automatic production, and better adapt to the needs of modern processing.

A method or device for integrated dosing and intermixing of small amounts of liquid, has a first liquid conveyed into or onto a first reservoir (3). A second reservoir (1) is entirely filled with a second liquid. The first and second liquids are brought into contact with each other via at least one joining duct structure (5) which has at least one area provided with a smaller cross section than the reservoirs (1,3) in the viewing direction of the connecting line between the two reservoirs (1,3). A laminar flow pattern is created along at least one portion of the joining duct structure (5), with the liquids thoroughly mixed in the second reservoir (1).

The invention belongs to the technical field of fracturing fluid recovery in the oil-field development process and particularly relates to an oil well fracturing flowback fluid recovering and desanding device. The oil well fracturing flowback fluid recovering and desanding device comprises a fluid storage tank, a buffer tank and a vibrating screen. The fluid storage tank is open. The buffer tank and the vibrating screen are both arranged on the top of the fluid storage tank. One side of the buffer tank is provided with a flowback fluid inlet. The buffer tank is communicated with the vibrating screen through a communicating pipeline. By the adoption of the oil well fracturing flowback fluid recovering and desanding device, flowback fluid can meet the performance requirement for reutilization after being treated and be applied to operation of a next well, so the harmless treatment cost of waste is lowered, t the flowback fluid polllutes the environment is reduced, construction materials are saved, and energy conservation and emission reduction are achieved. The oil well fracturing flowback fluid recovering and desanding device has the advantages that the settling time is short, continuous treatment of the flowback fluid can be achieved, and the occupied area of a settling pond is small, and is a oil well fracturing flowback fluid efficient recovering, separating, metering and storing device.
