ZX series self-priming pump is a horizontal self-priming centrifugal pump. Compared with other types of self-priming centrifugal pumps, this type of pump has the most simple structure because it has no check valve. It has the most reliable work. It has long working time without trouble, easy maintenance, easy to use, small size, light weight and high efficiency. Special considerations have been made in design, compared with pumps of the same diameter, with large displacement and high performance.

Bitcoin Mining Machine

Bitcoin mining machines are one way to obtain bitcoins. Bitcoin is an online virtual currency created by open-source peer-to-peer software. Instead of being issued by a specific currency institution, and produced by the massive computation of a specific algorithm, the Bitcoin economy uses a distributed database of nodes throughout the P2P network to identify and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin by producing a large number of coins.

Any computer can become a mining machine, but the returns will be low, and it may not mine a single bitcoin in a decade. Many companies have developed specialized Bitcoin mining machines with special mining chips that are tens or hundreds of times faster than normal computers.

Currency system by the user (the user through the key control wallet), trade (trade will be broadcast to the whole currency network) and miners (generated by competition calculation agreed on each node of the chain block, block chain is a distributed public authority books, contains the currency network of all the transactions happened)
Bitcoin miners manage the Bitcoin network by solving the problem of proof-of-work mechanisms with a certain amount of work -- confirming transactions and preventing double payments. Because hashing is irreversible, finding the number of random adjustments required to match is difficult, requiring a trial-and-error process that can predict the total number of times. This is where the proof-of-work mechanism comes into play. When a node finds a solution that matches the requirement, it can broadcast its result to the whole network. Other nodes can then receive the newly solved data block and check whether it matches the rule. If the other nodes calculate the hash value and find that the requirement (the operation goal required by Bitcoin) is satisfied, then the data block is valid and the other nodes accept the data block.
