Hello.
How wallets in blockchain produce private key without creation the same keys between all wallets installed? Is there a mechanism for identifying key private produced of the wallet after installing any wallet or running Web services?

No, it's not possible to prevent the same private key being generated twice.

A private key is a 256-bit number. The chances of ever generating the same private key more than once is something like, on average, 1 in 10000000 0000000000 0000000000 0000000000 0000000000 0000000000 0000000000 0000000000.
