长臂挖掘机:液压泵和液压马达的不同之处在哪?

日期:2019-08-29   来源:
  液压泵和液压马达是每个挖掘机上必不可少的液压元件,结构和工作原理也非常类似,有些行业外的小白有时还会把这两样东西搞混。有人说液压泵和液压马达像一对情人,一个攻一个受;有些人说液压泵和液压马达像发电机和电动机,一个身份两种岗位。这种描述对不对? 它们两者到底有什么区别呢?
  Hydraulic pump and hydraulic motor are indispensable hydraulic components on each excavator. Their structure and working principle are very similar. Sometimes, Xiaobai outside some industries will confuse these two things. Some people say that hydraulic pumps and motors are like a couple of lovers, one attacking and the other suffering; others say that hydraulic pumps and motors are like generators and motors, two positions of identity. Is this description correct? What's the difference between them?
  液压马达和液压泵的相似点:
  Similarities between hydraulic motors and pumps:
  (1)从原理上讲,液压马达和液压泵是可逆的,如果用电机带动时,输出的是液压能(压力和流量),这就是液压泵;若输入压力油,输出的是机械能(转矩和转速),则变成了液压马达。
  (1) In principle, hydraulic motors and pumps are reversible, if driven by motors, the output is hydraulic energy (pressure and flow), which is hydraulic pump; if the input pressure oil, the output is mechanical energy (torque and speed), it becomes a hydraulic motor.
  (2)从结构上看,二者是相似的。
  (2) Structurally, they are similar.
  (3)工作原理上看,二者均是利用密封工作容积的变化进行吸油和排油的。对于液压泵,工作容积增大时吸油,工作容积减小时排出高压油。对于液压马达,工作容积增大时进入高压油,工作容积减小时排出低压油。
  (3) In terms of working principle, both of them use the change of sealing working volume to absorb and discharge oil. For hydraulic pumps, oil is absorbed when the working volume increases, and high pressure oil is discharged when the working volume decreases. For hydraulic motors, high-pressure oil enters when the working volume increases, and low-pressure oil is discharged when the working volume decreases.
  液压马达和液压泵的不同点:
  The difference between hydraulic motor and pump:
  (1)液压泵是能源装置,而液压马达是执行元件。液压泵是将电机的机械能转换为液压能的转换装置,输出流量和压力,希望容积效率高;液压马达是将液体的压力能转为机械能的装置,输出转矩和转速,希望机械效率高。
  (1) Hydraulic pump is an energy device, and hydraulic motor is an executive component. Hydraulic pump is a device that converts mechanical energy of motor into hydraulic energy, and outputs flow rate and pressure, hoping for high volume efficiency; Hydraulic motor is a device that converts pressure energy of liquid into mechanical energy, outputs torque and speed, hoping for high mechanical efficiency.

  (2)液压马达输出轴的转向必须能正转和反转,因此其结构呈对称性;而有的液压泵(如齿轮泵、叶片泵等)转向有明确的规定,只能单向转动,不能随意改变旋转方向。
  (2) The direction of the output shaft of the hydraulic motor must be able to turn forward and reverse, so its structure is symmetrical; while some hydraulic pumps (such as gear pump, vane pump, etc.) have clear steering regulations, which can only rotate in one direction, and can not change the direction of rotation at will.
  (3)液压马达除了进、出油口外,还有单独的泄漏油口;液压泵一般只有进、出油口(轴向柱塞泵除外),其内泄漏油液与进油口相通。
  (3) In addition to the inlet and outlet of the hydraulic motor, there are separate oil leakage outlets; in general, only the inlet and outlet of the hydraulic pump (except the axial plunger pump), and the oil leakage in the hydraulic motor is connected with the inlet.
  (4)液压马达的容积效率比液压泵低。
  (4) The volume efficiency of hydraulic motor is lower than that of hydraulic pump.
  (5)通常液压泵的工作转速都比较高,而液压马达输出转速较低。另外,齿轮泵的吸油口大,排油口小,而齿轮液压马达的吸、排油口大小相同。
  (5) Generally, the working speed of the hydraulic pump is higher, while the output speed of the hydraulic motor is lower. In addition, the suction port of gear pump is large and the discharge port is small, while the suction port and discharge port of gear hydraulic motor are the same size.
