The invention relates to a low-water-consumption formation charging process. The process comprises the following steps: S1, clamping and fixing the end face of a semi-finished battery; s2, vacuumizing the inner cavity of the semi-finished battery, stopping vacuumizing when the vacuum degree of the inner cavity reaches delta 1, and injecting acid by adopting an acid injection nozzle until excessive acid is injected; s3, extracting excessive acid, and after acid extraction, lowering the liquid level to 0.3-0.5 time of the original liquid level before acid extraction; s4, vacuumizing the inner cavity of the semi-finished battery, stopping vacuumizing when the vacuum degree of the inner cavity reaches delta 2, and injecting acid by adopting an acid injection nozzle until excessive acid is injected; s5, extracting excessive acid, and after acid extraction, lowering the liquid level to 0.3-0.5 time of the original liquid level before acid extraction; s6, vacuumizing the inner cavity of the semi-finished battery, stopping vacuumizing when the vacuum degree of the inner cavity reaches delta 3, and injecting acid by adopting an acid injection nozzle until excessive acid is injected; and S7, extracting excessive acid, and carrying out charging formation. Compared with the prior art, acid filling is still needed when formation charging is carried out, the formation efficiency is improved, and water consumption is reduced.

The utility model discloses a plunger pump ice cream filling station which comprises a machine frame, a hopper is arranged on one side of the top of the machine frame, the bottom of the hopper is communicated with a feeding pipe, an installation base is arranged on the side, away from the hopper, of the top of the machine frame, and a servo motor is installed on the side face of the installation base. An eccentric crankshaft is rotationally connected into the mounting base, the output end of the servo motor is in transmission connection with the eccentric crankshaft, and a pump pipe is arranged at the bottom of the mounting base. The utility model relates to the technical field of ice cream production equipment, and solves the problems that in the prior art, a piston type filling machine or a screw type filling machine is adopted in a traditional filling station for quantitative filling of ice cream, and some problems exist in practical application, for example, the piston type filling machine is low in filling speed, material liquid leakage is prone to occurring, and the filling efficiency is low. The problems that raw materials are wasted and the production environment is not clean due to the fact that a screw-type filling machine is complex in structure, complex in disassembly and cleaning and not beneficial to keeping the sanitation of the production environment are solved.

The utility model discloses foaming and filling equipment for manufacturing and processing thermal insulation pipes, which is characterized in that a placing table is mounted in the middle of the top end of a foaming table, a lead screw motor is mounted on one side of the top end of the foaming table, the input end of the lead screw motor is electrically connected with the output end of an external power supply, and a rotating column is rotationally connected to the middle end of the bottom of the inner side of the placing table in an embedded manner; the two ends of the rotating column are connected with lead screws, and the lead screw located on one side of the rotating column is connected with the output end of the lead screw motor. The lead screw motor is arranged to drive the lead screws to rotate and drive the push plate and the mounting plate to be close to the two sides of the containing table at the same time; and meanwhile, the polystyrene foam filling tank is embedded and slides in the circular stop block in a matched manner, so that the external thread sleeve can completely extend into the gap between the outer pipe and the inner pipe, the gap between the outer pipe and the inner pipe is rapidly filled, the foaming agent filling speed is increased, and the product production efficiency is improved.
