After the installation of the hydraulic system is complete, why should the rows be laid before work?
Hydraulic system in the installation process will inevitably carry air into the system after the installation of the air inside the system will cause crawling, cavitation deterioration and other hazards, it is best to use after exhaust.
Do not exhaust the air will be mixed into the hydraulic oil, 1 formation of cavitation damage to the internal structure 2 affect the normal operation of the system 3 have a lot of noise.
Because after the end of your installation, the hydraulic system will certainly have air into, if not exhaust, will make the mechanical action is slow, or even no action, usually the hydraulic system exhaust, are after the start. If you are installing a hydraulic pump, it must be before the start of the air, or will make the hydraulic pump cavitation, issued a harsh sound, serious damage to the hydraulic pump, especially the gear pump, gear pump was particularly careful. Of course, many hydraulic systems are now automatic exhaust function. Hydraulic system
