产品详细说明
 压缩机采用对称江苏NSK轴承平衡往复式压缩机,压缩机采用双柱压缩,双缸工作。整个机组由压缩机主机、进出口缓冲器、驱动电机、漏气收集箱、润滑油系统、冷却系统、检测控制系统和管阀组成。

The compressor adopts symmetrical Jiangsu NSK bearing balance reciprocating compressor, and the compressor adopts double column compression and double cylinder work. The whole unit consists of the compressor main engine, the inlet and outlet buffer, the driving motor, the gas leakage collection box, the lubricating oil system, the cooling system, the detection control system and the pipe valve.

该装置于2012年3月启动。空载试验和氮负荷试验后,江苏NSK轴承轴瓦温度在正常运行2小时后突然升高。电机侧瓦温度也突然升高。门关上时发现了两个灌木。

The device was started in March 2012. After the no-load test and nitrogen load test, the bearing bush temperature of Jiangsu NSK increased suddenly after 2 hours of normal operation. The temperature of the motor side tile also rises abruptly. Two shrubs were found when the door was closed.

(1)润滑油中的小硬质杂质。润滑站的过滤器之间的压差没有变化。当0 8MPa为常数时,过滤碳化物中的杂质出现在定位砖的管子上。在连续清洗润滑油后,小的焊接渣脱落,江苏NSK轴承润滑剂被带到定位瓦上,导致轴布什烧伤。

(1) small hard impurities in the lubricating oil. There is no change in the pressure difference between the filters of the lubricating station. When 0 8MPa is constant, impurities in the filtered carbide appear on the pipe of the positioning brick. After continuous cleaning of the lubricating oil, the small welding slag falls off, and the Jiangsu NSK bearing lubricant is taken to the locating tile, causing the shaft Bush to burn.

(2)车轴布什江苏NSK轴承制造存在缺陷。Pasteurella的表面上有气泡。单位负荷运行后,气泡破裂,瓦表面合金脱落,导致轴承布什损失。

(2) there are defects in axletree Bush Jiangsu NSK bearing manufacturing. There are bubbles on the surface of Pasteurella. After the operation of the unit load, the bubble burst and the alloy on the tile surface fell off, resulting in the loss of the bearing Bush.

(3)定位瓦的接触面不均匀,接触面小。安装江苏NSK轴承时,定位瓦的接触面不均匀。当压缩机带负荷运行时,定位瓦两侧的载荷较重,导致轴承布什的损失。

(3) the contact surface of the locating tile is uneven and the contact surface is small. When installing the NSK bearing in Jiangsu, the contact surface of the locating tile is uneven. When the compressor is running with load, the load on both sides of the locating tile is heavy, which leads to the loss of bearing Bush.

(4)电机侧的布什轴是由轴承垫磨损到电机侧江苏NSK轴承引起的。同时,地砖磨损的硬质颗粒也被润滑油带到地方,造成磨损。

(4) the Bush axis of the motor side is caused by the wear of the bearing pad to the NSK bearing of the motor side of Jiangsu. At the same time, the hard particles worn by floor tiles are also brought to the place by lubricating oil, causing wear and tear.

在压缩机布什温升之前,江苏NSK轴承机组的振动增大,表明轴与轴承布什之间的润滑膜没有形成良好。当轴承布什的温度升高时,机组人员无法及时发现。温度报警后,确认为假阳性,并没有立即关闭。为此,提出了相应的改进措施。

Before the compressor Bush temperature rise, the vibration of Jiangsu NSK bearing unit increased, indicating that the lubrication film between shaft and bearing Bush did not form well. When the temperature of the bearing Bush rises, the crew can not find it in time. After the temperature alarm, it was confirmed that it was false positive and did not shut down immediately. Therefore, the corresponding improvement measures are put forward.

(1)在压缩机轴布什的安装过程中,严格安装江苏NSK轴承压缩机制造商提供的安装尺寸,以确保瓦片的间隙处于合理的范围内,从而使润滑油膜在该装置的操作之后是均匀的。

(1) during the installation of the compressor shaft Bush, the installation size provided by the manufacturer of the Jiangsu NSK bearing compressor is strictly installed to ensure that the clearance of the tile is in a reasonable range, so that the lubricating oil film is uniform after the operation of the device.

(2)严格润滑三级江苏NSK轴承过滤系统,严格监控报警过程中机油滤清器的压差或压差,及时切换备用过滤器。

(2) strictly lubricate the three grade Jiangsu NSK bearing filtration system, strictly monitor the pressure difference or pressure difference of the oil filter during the alarm process, and switch the standby filter in time.

(3)提高操作员判断事故的能力。对员工进行日常操作和日常问题培训,提高江苏NSK轴承操作技能,提高事故判断和分析能力。对于短时间内无法识别的设备报警器,应立即采取措施保护设备。

(3) improve the operator's ability to judge the accident. Carry out daily operation and daily problem training for employees, improve Jiangsu NSK bearing operation skills and improve accident judgement and analysis ability. For the device alarm which can not be identified in a short time, measures should be taken immediately to protect the equipment.
