  2:观察换向压力表,缓慢拧紧辅助阀块上换向溢流阀调节螺丝,将普通泵车换向压力设定为16Mpa后锁紧调节螺丝,将臂架阻尼泵车调整为18MPa。
  2: Observe the reversing pressure gauge, slowly tighten the adjusting screw of the reversing relief valve on the auxiliary valve block, set the reversing pressure of the ordinary pump truck to 16 Mpa, then lock the adjusting screw, and adjust the boom damper pump truck to 18 MPa.
  3:将发动机转速降低到怠速,观察换向压力表,最大要求为13Mpa,最小不允许降至零(即压力低于蓄能器)的现象;如果没有,机器必须关闭,以找出原因。
  3: Reduce engine speed to idle speed, observe the reversing pressure gauge, the maximum requirement is 13 Mpa, the minimum is not allowed to drop to zero (that is, the pressure is lower than the accumulator); if not, the machine must be shut down to find out the reason.

  5:搅拌压力调节:
  5: Stirring pressure regulation:
  1:将发动机转速调至1750±100rpmrpm,关闭搅拌电机进口球阀。此时,压力表显示搅拌系统的压力。
  1:Turn the engine speed to 1750+100 rpmrpm and close the ball valve of the stirring motor inlet. At this time, the pressure gauge shows the pressure of the mixing system.
  2:铜陵长臂挖掘机租赁检查混合反向压力继电器设置压力,慢慢收紧辅助阀块混合压力安全阀调整螺钉,搅拌约11.2 Mpa压力开关,搅拌叶片应该逆转趋势混合换向电磁阀(或值得电动),如不符合要求,然后调整混合逆压力继电器的压力,使其满足要求。

  2: Tongling long arm excavator lease check the setting pressure of hybrid reverse pressure relay, slowly tighten the adjusting screw of the mixed pressure relief valve of auxiliary valve block, stir about 11.2 Mpa pressure switch, and the stirring blade should reverse the trend of hybrid reversing solenoid valve (or worthy of electric power). If it does not meet the requirements, then adjust the pressure of the mixed reverse pressure relay. Make it meet the requirements.
  3.拔下搅拌反转电磁阀,将搅拌压力设置为12Mpa。
  3. Pull down the stirring reversal solenoid valve and set the stirring pressure to 12 Mpa.
  4:打开搅拌电机进口球阀,安装反搅拌电磁阀插头。
  4: Open the ball valve of the stirring motor and install the plug of the anti-stirring solenoid valve.
  6:洗涤压力调节:
  6: Washing pressure regulation:
  1:根据《泵车调试工艺规程》的要求,在水泵壳体上加注相应容量的油,并在调整水洗压力前排出泵电机。
  1: According to the requirements of "Technical Regulations for Pump Truck Debugging", oil of corresponding capacity is added to the pump shell, and the pump motor is discharged before adjusting the washing pressure.
  2:将发动机转速调整到1750rpm,关闭泵电机进口球阀,按下“清洗”按钮。此时,泵电机的压力显示在搅拌压力表上。
  2: Adjust the engine speed to 1750 rpm, close the ball valve of the pump motor and press the "cleaning" button. At this time, the pressure of the pump motor is displayed on the stirring pressure gauge.
  3:观察搅拌压力表,慢慢拧紧辅助阀块上泵电机压力溢流阀的调节螺丝,将泵电机的压力分别设置为4Mpa (ql-80型离心泵)和8MPa (7560C型),然后锁紧调节杆。
  3: Observe the stirring pressure gauge, tighten the adjusting screw of the pressure relief valve of the pump motor on the auxiliary valve block slowly, set the pressure of the pump motor to 4 Mpa (ql-80 centrifugal pump) and 8 MPa (7560C type), respectively, and then lock the adjusting rod.
  7:调节泵主溢流阀溢流压力和主油泵压力:
  7: Adjust the overflow pressure of the main relief valve and the main oil pump pressure:
  1:调节主溢流阀和主油泵的换向压力后,再调节主溢流阀和主油泵的压力。
  1: After adjusting the reversing pressure of the main relief valve and the main oil pump, then adjusting the pressure of the main relief valve and the main oil pump.
  2:拧紧主油泵上的调压杆D。
  2: Tighten the regulator rod D on the main oil pump.
  3:将发动机转速调至1750±100rpmrpm,按下后退按钮观察主系统压力表,缓慢拧紧主溢流阀调节螺丝,将主系统压力调至34±0.5mpa后锁紧调节杆。
  3:Turn the engine speed to 1750+100 rpmrpm, press the back button to observe the pressure gauge of the main system, tighten the regulating screw of the main relief valve slowly, and lock the regulating rod after adjusting the pressure of the main system to 34+0.5 mpa.
  4:铜陵长臂挖掘机租赁公司对单主油泵车主系统压力表进行观察,缓慢拧开单主油泵上的调压杆D,将主系统压力设置为32±0.5mpa,并锁紧调压杆。
  4: Tongling Long Arm Excavator Leasing Company observed the pressure gauge of the main system of single main oil pump, slowly unscrewed the pressure regulating rod D on the single main oil pump, set the pressure of the main system to 32+0.5 mpa, and locked the pressure regulating rod.
