Commissioning of hydra人答ulic universal testing讀坐 machine oil pump

Press the button on the dynamometer t厭樂able to start or stop the rotation of t中和he hydraulic universal t門理esting oil pump. When the fi土媽rst running or changing the w東電iring connector after insta風店llation, the groove wheel dire女靜ction should be observed, and業術 before starting to check whether the o數業il tank to the oil pump circuit is con書舊nected, if not, can properly tig電金hten the connection thr大能ead between the oil tank很分 and the tubing, oil Can e放內nter the oil pump.

In the first operation of the oil pump頻對, the side cover of the dynamome錯為ter is removed to ob友微serve whether there is an 林黑intermittent phenomenon of o自我il flowing back to the tank by the oil 黃藍supply valve. If there is 信吃such a situation, the upper M8 of th日道e oil pump can be blocked 廠森off to remove the air a站這nd then the oil in the o就雪il tank can be observed whe西刀ther the oil is intermi計西ttent. If there is such a phenome數妹non again, the hexagonal sc路員rew on the end surface of th拿女e oil pump can be screwed down. Push th河友e steel ball of the oil delivery v門討alve in the oil pump wi友鐘th a steel wire hook to observe whethe樹不r the steel ball jumps (when the oil 都中pump is in operation) an用村d after the steel ball moves, s著歌crew up the hexagonal scre兒自w, and the oil pump will wo開讀rk normally.

After the cylinder nozzle ma東服y also have air into the pipe, will a女車ffect the unsteady poin樹唱ter rotation, the elimination用電 method is to start the銀電 oil pump, close the ret是玩urn valve, open the feed valve, so t南男hat the main working pi器信ston rises a certain distance, and th朋見en open the return valve, so tha答員t the oil pump through the 到女working cylinder through the return計行 valve, back to the ta女明nk, such a cycle for a period of time.見黃 Time, the internal air c靜分an be discharged and the air is cl東件eared.
