The invention discloses a method for detecting the reaction performance of furnace slag and belongs to the field of metallurgy. The method adopts a system for detecting the reaction performance of thefurnace slag and is carried out according to the following steps: S1, preparing a slag system; S2, carrying out temperature-rising treatment on the slag system: weighing quantitative furnace slag andputting the furnace slag into a temperature-rising furnace; heating and melting; S3, grinding to prepare calcium oxide powder; S4, pressing calcium oxide sheets: pressing the calcium oxide powder into the calcium oxide sheets; and S5, adding the calcium oxide sheets and the furnace slag into a detection system and starting to detect. According to the method disclosed by the invention, the disadvantages in the prior art that subjective factor influences on the detection of the reaction performance of calcium oxide and the furnace slag are great and a detection result is not accurate are overcome; the furnace slag is injected into a calcium oxide groove to detect the time needed by dissolving the calcium oxide with a certain thickness through the furnace slag; and changes of a physical signal are used for judging whether reaction reaches a pre-set position, and the accuracy and detection efficiency of detecting the reaction capability of the calcium oxide dissolved in the furnace slag can be improved.

The invention relates to the technical field of motor vehicle hydraulic braking systems and provides a plunger type booster pump. The pump comprises oil inlet screws (1), a pump body (2), a different diameter plunger (3), seal rings (4), oil seals (5), a spring (6) and a spring base (7); when the braking oil pressure is lower in the stage of eliminating braking gap of the braking beginning of a motor vehicle, the output oil pressure Po is equal to the input oil pressure Pi, and after the braking gap is eliminated, when the input oil pressure Pi rises in the stage of braking working, the output oil pressure Po is higher than the input oil pressure Pi; the formula of the output oil pressure is shown in the description, wherein D is the large end diameter of the different diameter plunger (3), and d is the small end diameter of the different diameter plunger (3). The plunger type booster pump is simple in structure, convenient to process, small in size, low in cost and safe and reliable, saves energy, and can achieve boost effect under the condition that energy such as compressed air or vacuum source is not needed.

The invention discloses a high-flow long-life roll type reverse osmosis membrane element. The high-flow long-life roll type reverse osmosis membrane element comprises a central pipe, membrane bags and a water inlet grid. A water cavity is formed in the central pipe, and water passing holes are formed in the side wall of the central pipe and communicated with the water cavity. The membrane bags are wound on the central pipe, the water inlet grid is arranged between the membrane bags, and the interiors of the membrane bags are communicated with the water cavity through the water passing holes of the central pipe. The upper ends of the membrane bags and the upper end of the water inlet grid serve as raw water inlet ends, raw water is filtered through the membrane bags and then enters the water cavity of the central pipe, and the lower ends of the membrane bags and the lower end of the water inlet grid serve as concentrated water discharging ends. The thickness of the raw water inlet end and the concentrated water discharging end of the water inlet grid is larger than that of the middle of the water inlet grid, and thus a wide raw water inlet channel, a narrow middle water inlet channel and a wide concentrated water discharging channel are formed as the two ends of the water inlet grid are thick and the middle of the water inlet grid is thin. By means of the high-flow long-life roll type reverse osmosis membrane element, the pure water yield per unit time can be increased, the concentration polarization effect can be relieved, dirt is not likely to attach to the surfaces of reverse osmosis membranes, and thus the service life of the reverse osmosis membranes is prolonged.

The invention relates to the field of heat energy and power, in particular to a four-cylinder self-pressurization engine. The four-cylinder self-pressurization engine is a four-stroke internal combustion engine with four cylinders and comprises the four cylinders, namely, the first cylinder, the second cylinder, the third cylinder and the fourth cylinder, a first communicating channel, a second communicating channel and a third air door. The four-cylinder self-pressurization engine is characterized in that the second cylinder and the fourth cylinder are connected with the first communicating channel; the first communicating channel is connected with the second communicating channel through the third air door in a disconnectable mode; the second communicating channel is connected with the first cylinder and the third cylinder; and the second cylinder and the fourth cylinder can be transformed into superchargers after being shut down so as to provide supercharged air for the first cylinder and the third cylinder. The four-cylinder self-pressurization engine has the beneficial effects that firstly, an existing cylinder deactivation technology is improved, and the surcharging effect is achieved by transforming two of the cylinders into the superchargers after the two cylinders are shut down for supercharging the other two cylinders; and secondly, the two superchargers are used for surcharging the other two cylinders together, and a certain supercharging effect can be achieved.
