How to increase the service life of screw nut in electric screw press?
91y游戏苹果下载安装 The screw and nut of the electric screw press rotate frequently, the phenomenon of wear is inevitable, the price of a set of screw nut is quite high, which increases the production cost of the enterprise greatly.
91y游戏苹果下载安装 Initially, the screw nut of the electric screw press was exposed, as shown in the figure below.
91y游戏苹果下载安装 When the bare leakage is outside, the dust is constantly eroding, resulting in the existence of dust particles between the screw nuts, and the continuous lubrication will cause serious oil leakage and other problems. It not only affects the appearance but also increases the difficulty of equipment maintenance.
91y游戏苹果下载安装 Lubrication and dust are important external factors affecting the life of screw nut.The dust pollution in refractory industry is large, so there are the following protection measures in the market, as shown in the figure below.
Static - Piston
91y游戏苹果下载安装 Sealing ring can isolate a small part of the dust but can not put an end to the phenomenon of oil leakage, semi-seal can solve the phenomenon of oil leakage, can not solve the problem of dust erosion, very troubkle to replace. Static pressure is not only an effective way to isolate the external dust, but also a continuous lubrication of the screw nut to form an oil film, which can completely solve the oil leakage phenomenon.
From the above analysis, it can be seen that the fully sealed static electric screw press is the ideal structure for reducing the wear of screw nuts.Due to the full seal static pressure type, the screw and nut are always immersed in the oil cylinder.
91y游戏苹果下载安装 The lubricating oil in the oil cylinder is recycled after purification and filtration to reduce the friction generated by the transmission, which plays a good protection role, and also avoids the abrasion and scratch caused by artificial refueling.
The service life of the screw nut can be increased by 3-5 times, which greatly reduces the maintenance cost of the equipment in the later period. Therefore,full seal static pressure is an effective method to increase the service life of the screw nut of the electric screw press.
