强夯机在高原的正确打开方式

强夯工法因为处理高能、成本低,被广泛应用于机场、厂房等地基预处理中。但不是所有的强夯机都能到高原地区施工的,因为标准强夯机只满足2000m海拔以内,气温-10℃~40℃内使用,如果海拔过高,它也会和我们人一样,出现高原反应。那如何解决这个问题,保证设备的高出勤率,今天我就和大家一起探讨一下:
Dynamic compaction method is widely used in foundation pretreatment of airports and factories because of its high energy and low cost. However, not all dynamic compaction machines can be used in plateau areas, because the standard dynamic compaction machine can only be used within 2000m altitude and the temperature is - 10 ℃ ~ 40 ℃. If the altitude is too high, it will also have plateau reaction like us. How to solve this problem and ensure the high attendance rate of equipment, today I'll discuss with you:
一、动力系统:它是我们整车的动力源,随着海拔升高,空气密度降低,发动机的有用输出功率下降,散热功率升高,因此针对高原施工车辆,应该主要关注以下几个方面:
1、 Power system: it is the power source of our whole vehicle. With the increase of altitude, the air density decreases, the useful output power of the engine decreases and the heat dissipation power increases. Therefore, for plateau construction vehicles, we should mainly focus on the following aspects:
1、评估发动机的功率是否满足液压主泵需求,及时调整主泵功率,避免发动机因负载过高产生憋车现象;
1. Evaluate whether the power of the engine meets the requirements of the main hydraulic pump, and adjust the power of the main pump in time to avoid holding the engine due to excessive load;
2、提高水箱压力盖开启压力(建议开启压力少1.1kPa以上),避免冷却液低温开锅,影响散热,并根据使用工况重新评估、调整散热系统;
2. Increase the opening pressure of the pressure cover of the water tank (it is recommended that the opening pressure be at least 1.1kpa), avoid the low-temperature boiling of the coolant, which will affect the heat dissipation, and re evaluate and adjust the heat dissipation system according to the service conditions;
3、要根据当地低气温条件,及时更换相应规格冷却液、燃油、机油或者加装发动机冷启动装置,避免水箱冻裂,保证发动机低温环境下正常启动。
3. According to the local low temperature conditions, timely replace the coolant, fuel and oil of corresponding specifications or install the engine cold start device to avoid the freezing crack of the water tank and ensure the normal start of the engine under low temperature environment.
二、液压系统:它是我们整车的“血液循环系统”,因高原地区环境温度低,正常配置的46#液压油已不满足使用要求,容易造成低温条件下,因液压油流动性不好,润滑不到位,造成主要液压元件泵、马达的磨损,缩短其使用寿命。因此需要根据环境温度情况,选择合适牌号的抗磨液压油。另外,为防止液压油箱吸空,需要将液压油箱空气滤清器更换为手动排气预压式空气滤清器。
2、 Hydraulic system: it is the "blood circulation system" of our whole vehicle. Due to the low ambient temperature in plateau areas, the 46# hydraulic oil normally configured does not meet the use requirements, which is easy to cause the wear of main hydraulic components pumps and motors and shorten their service life under low temperature conditions due to poor fluidity and inadequate lubrication of hydraulic oil. Therefore, it is necessary to select the appropriate brand of anti-wear hydraulic oil according to the ambient temperature. In addition, in order to prevent the hydraulic oil tank from being empty, it is necessary to replace the hydraulic oil tank air filter with a manual exhaust preloading air filter.
三、润滑系统:它是设备能长期可靠运行的保障,包含发动机润滑系统和减速机润滑等,一台好的设备离不开后期细心的呵护保养,而润滑油品的选择尤为重要,不仅要选择正规渠道油品,而且要根据温度条件,选择合适的润滑油牌号,才能对润滑部位起到有用保护。
3、 Lubrication system: it is the guarantee for long-term and reliable operation of equipment, including engine lubrication system and reducer lubrication. A good equipment is inseparable from careful care and maintenance in the later stage, and the selection of lubricating oil is particularly important. It is necessary to select not only regular channel oil, but also appropriate lubricating oil brand according to temperature conditions, In order to effectively protect the lubricated parts.
