Provided are a pressure-pump cartridge and a pressure pump, where the pressure-pump cartridge includes a cylinder, where the cylinder has a first chamber, a piston chamber and a second chamber hat are in communication in sequence, and the piston chamber is used for being in sealing fit with a piston. An end of the first chamber remote from the piston chamber is provided with a first opening allowing entry of the piston, and during installation, the piston enters the first chamber by the first opening and enters the piston chamber after passing through the first chamber, and meanwhile, the first chamber is configured to be in a clearance fit with the piston, such that the size of the first chamber is larger than that of the piston.

The present disclosure discloses an electric border gateway device which adopts the blockchain technology to implement communication authentication and data transmission encryption at the gateway. As a device for sinking and processing local information, the border gateway device may build not only a local blockchain network with a variety of local electric sensing terminal devices, but also a regional blockchain network with other border gateways and electric management platforms. As a critical node of these two types of blockchain, the border gateway may enable the authentication of identity legality between electric sensing terminal devices, the critical data storage in the blockchain ledger, the deployment and implementation of blockchain transaction by control and coordinated functions, and the safe and reliable data interaction. The present disclosure also discloses a method for chaining and storage of sensing data based on the electric border gateway device.
