NVR is called network hard disk video recorder. The main function of NVR is to receive digital video stream transmitted by IPC (network camera) equipment through the network, and store and manage it, so as to realize the advantage of distributed architecture brought about by network. In simple terms, with Nvr, you can view, browse, play back, manage, and store multiple network cameras at the same time. Get rid of the computer hardware, no longer have to face the complexity of installing software.
A TV or a monitor has only one display function that has no data conversion or decoding function. The signals transmitted through digital microwaves cannot be directly displayed. If it is connected to a PC, it has its own decoding function, and it can be directly connected.
Similarly, a wireless bridge is just a transmission device, the main role is to send signals and receive signals. Equivalent to the role of network cable. It is a function without any conversion itself. It's just a faithful transmitter. Often customers will ask, can you convert to what signal, ah, can not be compatible with what signal, here to give you a reply is that you just when our wireless bridge is a network cable, in addition to the transmission function, it does not Other effects. As long as it is a network signal, it can be transmitted. As for other functions such as conversion, you need to implement it yourself.
This is just a general principle, more questions, you can call the Leian to answer your questions.
Drilling equipment is used for drilling and construction of this specific conditions of the mechanical devices and equipment, divided into drilling equipment and Drilling tools two categories. Drilling equipment mainly by drilling rig, mud pump and mud purification equipment, mud mixer, drilling tower and other components,and drling tools includes driling pipe, adapter/kelly and collar.
Friction welding drill pipe and adapter
Friction welding drill pipe and adapter are in accordance with API SPEC 5DP and SY/T5561-2008 Specifications.The steel grade are DZ250,R780,G105,S135 that are after partly or overall heat treatment.The adapter part adopts thermal refining to superior alloy steel 35CrMo or 4137H that`s after thread hardening treatment and phosphating to better antiseize.It also can be produced upon customers` requirements.
