低成本、率、以工作质量保证产品质量

液压油在液压系统中起传递动力的作用，而且还起着润滑、冷却、清洗等作用。油液品质的好坏，直接影响液压系统的工作性能。对于泰安合力叉车液压油的检査，可按以下方面进行：

Hydraulic oil plays the role of transmitting power in the hydraulic system, and also plays the role of lubrication, cooling and cleaning. The quality of the oil directly affects the working performance of the hydraulic system. The inspection of hydraulic oil of Taian Heli forklift can be carried out as follows:

检查合力叉车液压油自身的劣化程度。一般液压油经长期使用后，由于温度、空气中的氧、水分及光照等作用，油液品质会逐渐恶化，通常表现为密度、粘度、酸值增高，闪点、抗乳化性能降低以及产生油泥等。

Check the deterioration of hydraulic oil of Heli Forklift. After long-term use of general hydraulic oil, due to the effects of temperature, oxygen, water and light in the air, the quality of the oil will gradually deteriorate, usually manifested by increased density, viscosity, acid value, reduced flash point, anti-emulsification performance and sludge.

检查液压油内混入水分的程度。工作过程中，要定期检査水分的混入程度，当水分超过使用界限时，应该换油。

Check the degree of water in the hydraulic oil. During operation, check the degree of water mixing regularly, and change the oil when the water exceeds the service limit.

油水混合成白浊状时，不能使用，应更换。

When the oil and water are mixed into white and turbid, they cannot be used and should be replaced.

合力叉车系统中的油应能循环流回储液罐，在管路中不停止，系统工作时间长，停止工作时间短，液压油内混人水分质量不超过0.1%。

The oil in the resultant forklift system shall be able to circulate back to the storage tank, and it will not stop in the pipeline. The system will work for a long time and stop working for a short time. The water content in the hydraulic oil will not exceed 0.1%.

管道很长，系统中油不能流回储液罐或不能完全循环，液压油内混入水分质量不超过0.05%。

The pipeline is very long, and the oil in the system cannot flow back to the storage tank or can not be completely circulated. The mass of water mixed in the hydraulic oil does not exceed 0.05%.

管道中油长时间不能流动，液压油内混入水分质量不超过0.03%。

The oil in the pipeline cannot flow for a long time, and the mass of water mixed in the hydraulic oil shall not exceed 0.03%.

判断泰安合力叉车液压油中是否混有水分。简单方便的办法是取一块加热铁板，把需试的油滴于铁板上，如能听到显著响声，则说明油中有水，且水分越多，响声越大。

Judge whether there is water in the hydraulic oil of Taian Heli forklift. A simple and convenient way is to take a heating iron plate and drop the oil to be tested on the iron plate. If a significant noise can be heard, it means that there is water in the oil, and the more water, the louder the noise.

检查液压油被污染的状况。一般的液压装置，液压油中含有机械杂质的使用界限为每100mL油液中污染物的含量不超过7-10mg。机械杂质含量可以通过滤纸过滤油液、测量其重量的方法测定。更多相关内容就来我 们网站http://www.jnhgjx.net咨询！

Check the hydraulic oil for contamination. For general hydraulic devices, the use limit of mechanical impurities in hydraulic oil is that the content of pollutants in every 100mL of oil is not more than 7-10mg. The content of mechanical impurities can be determined by filtering the oil with filter paper and measuring its weight.
