The domestic appliance W is equipped with a liquid pump 1, wherein the liquid pump 1 has a pre-chamber 2 and a main chamber 3, wherein the pre-chamber 2 has a filling opening 4 for filling liquid K; the pre-chamber 2 and the main chamber 3 are connected to one another via a passage opening 5 which lies at a lower point than the filling opening 4; the main chamber 3 has an outlet opening for discharging the liquid K and a pressure opening 8 which is connected to an air pump 7; a valve element 9 is arranged in or with the main chamber 3, which valve element 9 is controlled by the filling level and is set up and arranged to close the passage opening 5 when a maximum filling level hmax is reached in the main chamber 3; wherein at least one filling-level sensor 10 is arranged on or in the pre-chamber 2, by means of which filling-level sensor 10 the reaching of an activation level (ha) in the pre-chamber 2 can be sensed; and wherein the liquid pump 1 is set up to activate the air pump 7 for a defined time period when the activation level ha is reached.

The invention relates to the technical field of agricultural irrigation equipment, in particular to a multi-purpose intelligent sprinkling irrigation vehicle. The sprinkling irrigation vehicle comprises a vehicle body, and a water storage tank and a water pipe winding mechanism are arranged on the vehicle body; a switching valve is arranged on the water storage tank, a water inlet of the switchingvalve is communicated with the water storage tank, a water outlet of the switching valve is communicated with a water pipe, and the switching valve is used for switching on or switching off the watersupply of the water pipe; a water amount control device is further arranged on the water storage tank and comprises a displayer, a controller and a water level sensor, and the water level sensor andthe displayer are both in signal connection with the controller; the water pipe winding mechanism comprises a bracket, a winding shaft and the water pipe, wherein the winding shaft and the water pipeare arranged on the bracket; a water pumping device and a filtering sleeve are arranged on the bracket, the filtering sleeve is used for filtering out debris attached to the side wall of the water pipe, and spraying ports are formed in the inner side wall of the filtering sleeve. According to the provided multi-purpose intelligent sprinkling irrigation vehicle, the water pipe can be cleaned aftersprinkling irrigation, residual water in the vehicle is removed, and the situation that the next use is affected is avoided.

The invention belongs to the design and manufacture of nuclear power plant equipment, and specifically relates to a filter for an emergency core cooling system that takes into account both filtering and drainage functions, including an upper filter assembly and a pumping sump. The upper filter assembly includes a flow channel and a filter screen. There is a gap between the replacement material tanks, and a sinking filter assembly is installed inside the pump intake pit. The upper end of the pump intake pit is provided with a pit mouth. The length and width of the pit mouth are larger than the pit mouth of the pump intake pit. Lower than the bottom surface of the built-in refueling water tank, the sunken filter assembly is lower than the bottom surface of the built-in refueling water tank; this device can provide low water level water to enter the pump to take water when the water level in the built-in refueling water tank is lower than the lowest point of the upper filter The channel of the pit is further discharged by the safety system pump and transported to the reactor refueling pool to meet the needs of refueling or maintenance.

The invention discloses a vapor pressure testing device and a method for easy-sublimation solid energetic materials. The device comprises a vacuum pump, a sample pool, an equalizing pipe, an air gauge and a heating furnace. A solid sample inlet (35) is arranged on the sample pool (34), liquid storage spheres (31, 33) are respectively arranged on two sides of a zero position gauge pipe (32), mercury is filled inside the zero position gauge pipe (32), the sample pool (34) is communicated with the liquid storage sphere (33) via the equalizing pipe (19), and a vacuum air passage hose (12) is arranged between the other end of the liquid storage sphere (31) and the air gauge (9). The device and the method can measure vapor pressure data of the easy-sublimation solid energetic materials, realizeautomatically controlling test procedure and automatically acquiring, analyzing and processing test data, have safe test procedure and accurate result, and can meet engineering needs.
