Grate cold confidential slider add lubrication to extend the use cycle

Grate cold confidential letter slider 2020 - add lubrication to extend the use cycle 06 - 30 zhang wei ChuYanPeng Lv Donghai ( Shandong spring xing cement co. , LTD. ) A, problems a company & Phi; 4. 8米× 74 MB of rotary kiln, grate cold model number: NC42340, production capacity: 5000 ~ 6000 t/d, the material temperature: 1400 degrees Celsius, discharge temperature: 65 ℃ + environment temperature, grate bed area: 133. 2 ㎡, stroke: 4 ~ 25 times/min, three sections of transmission. Grate, captain time of cold sealing the slider under the slider shaft drive, hydraulic cylinder operation frequency 25 times/min, the long-term dry friction lubrication, wear is larger, as the skateboard wear only can adjust the bolt fastening the slider, but after adjusting for several times, skateboard internal compression adjusting spring failure, seal clearance, skateboarding and slider shell lose sealing effect, make interior ministry under the grate cooling air outside, through the clinker cooling air containing dust and small particles of clinker, serious environmental pollution, reduce the service life of the seal the slider. The hydraulic cylinder piston rod seal damage will cause the hydraulic cylinder oil, hydraulic cylinder movement to the piston rod back and forth on the adhesion of tiny clinker dust into the hydraulic cylinder hydraulic cylinder piston seal damage internal, strain hydraulic cylinder wall, the whole hydraulic system pollution. Second, the solution to grate cooler mainly adopt centralized two lubrication, joint bearing at the end of the hydraulic cylinder head has the lubrication points, each class time open lubricating oil pump oiling 2 times, each time 30 min. Due to the hydraulic cylinder joint bearing chamber storage is less, while the distributor preview trip to a minimum, there is still a spill, wasteful. Solution is joint bearing lubrication points at the end of the hydraulic cylinder with four-way, using 10 mmpu trachea respectively connected to the seal on the slider, in a sealed sliding block before and after the drill a hole of fixed contact, through add the lubricating oil pipe, seal the slider for lubrication and sealing effect, See figure 1) 。 Lubrication time grate cooler with other lubrication points at the same time, at the bottom of the slide block processing a 400 mm & times; 150 mm oil collecting box to prevent oil spill pollution again, Field application effect is shown in figure 2) 。 Three, the transformation effect, after the operation, the sealed sliding block inside skateboard got lubrication, reduced the dry friction, improve the surrounding environment, no replacement seal slider, use more than 3 years, but also prolong the service life of the hydraulic cylinder.
