腐蚀不仅影响镇江NSK轴承精度和表面粗糙度,而且还降低了使用寿命,甚至报废,不能使用。
Corrosion not only affects the precision and surface roughness of Zhenjiang NSK bearing, but also reduces the service life, even scrap, can not be used.
轴承防锈工作是一项重要工作,特别是在轴承加工过程中,如酸洗、清洗、磨削等工艺在热处理车间,有许多工序。当产品不是流水线时,它是按顺序的方式。
Bearing anti-rust work is an important work, especially in the bearing processing process, such as pickling, cleaning, grinding and other processes in the heat treatment workshop, there are many processes. When the product is not pipelined, it is in a sequential manner.
加工后,须存放在中间仓库,所以轴承圈之间的存放过程须防锈。
After processing, it must be stored in the intermediate warehouse, so the storage process between the bearing rings must be rustproof.
经与相关厂家解决关键问题后,多年的生产实践表明,工艺间生锈几次增加,防喷效果较好。首先,对镇江NSK轴承轧辊进行了防锈试验。半成品和成品每天用亚硝酸钠溶液洗涤一次。三个月后,没有发现锈迹。对轴承套圈的半成品进行喷涂和腐蚀,效果相同。喷淋式防锈技术比较简单。
After solving the key problems with the relevant manufacturers, many years of production practice shows that rusting between the processes has increased several times and the blowout prevention effect is better. First, the rust proof test of NSK bearing roller in Zhenjiang is carried out. Semi finished products and finished products are washed with sodium nitrite solution once a day. Three months later, no rust was found. The semi-finished products of the bearing rings are sprayed and corroded with the same effect. Spray type rust prevention technology is relatively simple.
根据半成品仓库,它可以建在人行道上,中间约1.5米,地面水泥地面中间仓库通过镇江NSK轴承汽车轴承环。在通道的末端安装有用于储存水性亚硝酸钠的罐。配方为5~10个百分点亚硝酸钠加0.6个百分点碳酸钠。沟是在地上做的。然后将轴承环堆放在两侧的地板上。每个轴承环之间有一个0.6米的人行道。可以认为,中间仓库的设计约为64平,亚硝酸钠溶液池1m3。
According to the semi-finished warehouse, it can be built on the pavement, the middle of about 1.5 meters, the ground cement ground intermediate warehouse through the Zhenjiang NSK bearing automobile bearing ring. A tank for storing aqueous sodium nitrite is installed at the end of the passage. The formula is 5~10 percentage point sodium nitrite plus 0.6 percentage points sodium carbonate. The ditch is made on the ground. Then the bearing rings are stacked on the floor on both sides. There is a 0.6 meter sidewalk between each bearing ring. It can be considered that the design of the intermediate warehouse is about 64 flat, and the sodium nitrite solution pool is 1m3.
每天早晨用亚硝酸钠溶液清洗轴承圈一次。溶液通过泵抽吸水箱,并通过橡胶软管进入淋浴喷头。洗涤后,水溶液从后通道再循环到池中。在回水沟底部的上部,用丝绸、纱线、织物和灰尘进入水箱。镇江NSK轴承中间仓库要干净整洁。池中的溶液每两天进行一次测试,并根据测试结果进行补充。罐内溶液的更换周期是在不同月份进行的。从四月到九月,每两周更换一次,从十月到3月。
Wash bearing rings once every morning with sodium nitrite solution. The solution pumps the water tank through the pump and enters the shower nozzle through a rubber hose. After washing, the aqueous solution is recirculated from the back channel to the pool. In the upper part of the bottom of the back drain, enter the water tank with silk, yarn, fabric and dust. Zhenjiang NSK bearing intermediate warehouse should be clean and tidy. The solution in the pool is tested every two days and supplemented according to the test results. The replacement period of the solution in the tank is carried out in different months. From April to September, it is changed every two weeks, from October to March.
结论喷雾除鳞方便、省力。过去,中间仓库里的两个人没有生锈。现在一个人可以同时做其余的工作。2003年3月有7002136卷,3620卷,4000卷。此外,化学品的消耗也大大减少。过去,磨坊每月消耗亚硝酸钠超过4000公斤,但现在只有200公斤,节省了近一半。
Conclusion spray descaling is convenient and labor-saving. In the past, two people in the intermediate warehouse did not rust. Now one can do the rest of the work at the same time. In March 2003, there were 7002136 volumes, 3620 volumes, and 4000 volumes. In addition, the consumption of chemicals has also been greatly reduced. In the past, the mill used to consume more than 4,000 kg of sodium nitrite a month, but now only 200 kg, saving nearly half.
