              濟南登車橋壓力失常怎么回事?

              1、濟南登車橋http://www.pzqsb.com/油泵轉向不對,根本無壓力油輸出,系統壓力一點也不上去;因電機 轉速過低,功率不足,或者油泵使用日久內部磨損,內泄露大,容積效率低,導致油泵輸出流量不夠,系統壓力不夠。
              Jinan Ramps steering pump is wrong, absolutely no pressure oil output, the system pressure is not up; because the motor speed is too low, insufficient power, or prolonged use of internal pump wear, inner leak, low volumetric efficiency, resulting in pump output flow enough, the system pressure is not enough.

              2、濟南登車橋液壓油泵口裝反,而泵又是不可反轉泵,不但不能上油,而且還沖壞油封;泵吸油管太小,吸油管密封不好漏氣,油液粘度太高,濾清器被雜質污物堵塞,也將造成泵吸油阻力大產生吸空現象,使泵的輸出流量不夠,系統壓力上不去。
              Ramps mouth Jinan hydraulic pump installed backwards, and the pump is not reversible pump, not only oil, but also washed out seal; pump suction pipe is too small, suction pipe leak seal is not good, the oil viscosity is too high,impurity filter is clogged with dirt, it will cause the pump to suck air resistance generated big phenomenon, the pump output flow is not enough, the system pressure go up.

              3、濟南登車橋溢流閥等壓力調節閥故障,溢流閥閥芯卡死在大開口位置,油泵輸出的壓力油通過溢流閥流回油箱,使壓力油與回油路短接。
              Jinan Ramps and other pressure relief valve malfunction, relief valve stuck in the open position big, pump output pressure of the oil back into the tank through the relief valve, the pressure oil and return oil shorted.

              4、濟南登車橋http://www.pzqsb.com/在工作過程中若發現壓力上不去或壓力下不來,則很可能是換向閥失靈,導致系統卸荷和封閉,或是由閥芯與閥體孔之間嚴重內泄露所致。
              Jinan Ramps If it is found in the work process falters pressure or pressure get down, it is likely that valve malfunction, causing the system unloading and closed within or severe leakage between the spool and valve hole caused by.
