挖掘机毛病:热车、冷车憋车你都分得清吗?

日期:2019-07-23   来源:上海体彩网http://www.rbaras.com
  在挖掘机的使用中,经常遇到各种各样的问题,“憋车”是一个常见的问题,也可以称为“憋机”、“闷车”等。挖掘机“憋车”的方式有哪些?是什么原因让我们踌躇不前?今天我要给大家做一个简单的介绍。
  In the use of excavators, we often encounter a variety of problems, "traffic jam" is a common problem, also known as "traffic jam", "stuffy" and so on. What are the ways of "holding up" excavators? What are the reasons for our hesitation? Today I want to give you a brief introduction.
  在工作安装中(大臂、前臂、斗)动作、履带行走、或转盘旋转时,发动机转速急剧下降,形成发动机冒烟甚至停机,这种现象就是“发动机失速”,俗称“憋车”。挖掘机“憋车”问题有三种表达方式:热车“憋车”、冷车“憋车”、冷车热车都“憋车”。。下面是每种情况的原因。
  When working and installing (arm, forearm, bucket), crawler walking, or turntable rotating, the engine speed drops sharply, resulting in engine smoke or even shutdown. This phenomenon is "engine stall", commonly known as "holding up the car". There are three ways to express the problem of "holding up" of excavators: hot car "holding up", cold car "holding up", cold car "holding up" and hot car "holding up". Here are the reasons for each situation.
  挖掘机热车 “憋车”
  Hot truck of excavator "hold up"
  挖掘机故障:热车、冷车挡不住车你能看出来吗?
  Excavator failure: Hot car, cold car can not block the car, can you see it?
  当发现挖掘机热车“憋车”问题时,需要进行维修,常见的问题原因有以下五点:
  When the problem of "holding up" of excavator hot car is found, it needs to be repaired. The common causes of the problem are as follows:
  1. 黑烟可能是由于油路、油泵、发动机进气口、发动机三个滤清器等故障造成的。
  1. Black smoke may be caused by the faults of oil circuit, oil pump, engine intake, engine three filters and so on.
  2. 液压泵或分配阀发生泄漏,形成泵的功率大于引发器的功率。

  2. Hydraulic pump or distribution valve leaks, and the power of the pump is greater than that of the initiator.
  3.如果热车因油路问题而停车,请及时检查油路,因为油路可能会发生变化或太脏。
  3. If the hot car stops because of the problem of the oil line, please check the oil line in time, because the oil line may change or be too dirty.
  4. 热车是高压油泵中泄漏量增加而形成的“拦阻”,需要对油泵进行标定。
  4. Hot truck is the "obstruction" formed by the increase of leakage in high-pressure oil pump, which needs to be calibrated.
  5. 泵调节器磨损、泵阀组压力流量过大、泵内部部件磨损等原因。
  5. The causes of abrasion of pump regulator, excessive pressure and flow of pump valve group, abrasion of internal parts of pump, etc.
  挖掘机冷车“憋车”
  "Holding up" of Excavator Cold Car
  挖掘机故障:热车、冷车挡不住车你能看出来吗?
  Excavator failure: Hot car, cold car can not block the car, can you see it?
  冷挖机“憋车”的原因可能是:
  The reason of cold excavator "holding up" may be:
  1. 发动机转速或负载功率不足。
  1. Insufficient engine speed or load power.
  2. 挖掘机的泵压不正确。
  2. The pump pressure of excavator is incorrect.
  3.执行机构的阀门间隙过大/过小。
  3. Valve clearance of actuator is too large/too small.
  4. PRV电磁阀电压不足。
  4. PRV solenoid valve voltage is insufficient.
  5. 柴油标识错误,低温柴油粘度高,供油不足。
  5. Mislabeling of diesel oil, high viscosity of low temperature diesel oil and insufficient oil supply.
  挖掘机冷车热车“货舱”
  Excavator cold car hot car "cargo hold"
  如果挖掘机冷车热车两种情况“憋车”?这一问题是近年来在使用移动电话的长挖掘机上普遍存在的。原因是:
  If the excavator cold car hot car two cases "hold up"? This problem is widespread in recent years in the use of mobile phones on long excavators. As a result of:
  1. 柴油机油泵(高压油泵)喷嘴不工作。
  1. Diesel engine oil pump (high pressure oil pump) nozzle does not work.
  2. 启动程序的权力过大。
  2. Excessive power to initiate procedures.
  3.泵和阀组的压力和流量过大。
  3. The pressure and flow rate of pump and valve group are too large.
  4. 长时间不换油等。
  4. No oil change for a long time.
  面对挖掘机的“憋车”,首先要根据情况找出原因,有能力处理好问题,保证消费。
  Faced with the "traffic jam" of excavators, first of all, we should find out the reasons according to the situation, have the ability to deal with problems and ensure consumption.
