Type introduction:

    ONE、 The ore uses the main structure characteristic of the bit：
    The ore that our company produces calm the anger and arrange the dreg bit for the air-cooled bearing by three gear wheels of bits， Used in metallurgy， coal， chemical industry， building materials， mine，etc。 and the big gun hole in the project。 mainly by bit body， gear wheel， bore tooth， bearing， block bit dreg spray nozzle，etc。 Have the following structure characteristics mainly：
     1、Gear wheel surface inlay and equip with thick crystalline grain high-quality alloy post tooth， its intensity is high， wear-resisting ；Cloth tooth position and tooth shape through optimization design， tooth rational cloth have ， lose the tooth ， Broken rock that can be effective；
     2、slip pair( roller)， stop and push away pair amount to and five block bearing assemble making up after process accurately bearing system is by roller - steel ball - stop and push pair， The work is reliable ， performance is fine。 Roller bearing and slipping the bearing to bear the radial load， stop pushing the bearing and bearing the axial load， Ball bearing play and make a reservation and lock function of gear wheel mainly， and bear some loads。
     3、Spray nozzle belong to person who can change， can change the spray nozzle according to the air compressor machine pattern that the rig is buy and spend， By winning necessary wind pressure wind amount。
     4、Entering the bearing in order to defend the rock bits， the bit can be loaded and go against to stop the valve。
     5、Join whorl as standard regular type， accord with standard， API of U。S。A。， can guarantee with smooth to join reliably drilling rod。

     TWO、 The type of the bit expresses the method：

Note： Add the meaning of the characteristic： F：Bring and go against and stop valve Z： centre spray nozzle B： better to protect the foot-path
