Little knowledge about hydraulic sand making machine

Hydraulic products range, through constant contact and use will understand more, today Xiaobian to introduce the relevant knowledge of hydraulic sand making machine.

Daily maintenance of hydraulic sand making machine: a lubricating oil (ZL-3 lithium grease) is added to the slideway of the main bearing and the movable bearing block every day with the manual oil pump, and the fuel is no less than 60ml per day. Always check the bolts are loose, timely fastening. Make the operation record of hydraulic sand machine, pay attention to the change of current, temperature, vibration and sound. Once found abnormal, timely analysis, find the fault point and deal with.

Periodic maintenance of hydraulic sand making machine:

Reducer should add N46 mechanical oil. The first operation 300~6000 hours, oil change, then every operation 1500~5000 hours must be replaced oil. Mainly determined by the working environment, the longest shall not exceed 12 months. Motor in general circumstances, its bearings can be changed 5000 hours grease (ZL-3 lithium grease), for the use of closed bearings motor, bearings can not be changed grease.

The bearing of the main engine is checked in general for two years. The wear condition of the bearing is determined and the replacement is decided according to the wear condition. If the gasket is intact or timely change mat, not into the dust, bearing can not be changed for several years. The pressure of the spring device is very important to the moving roller machine; it determines the breaking effect of the specific feeding particle size for the specific hardness. If the spring is too frequent reciprocating, it may be due to long-term fatigue and pressure to the bottom. The upper and lower plates can be cut and adjusted again by press.

Roller surface normal welding: General 10~12 months: use electric wire brush to clean the surface of the materials and debris, if not brush off, can be hand grinding wheel or angle grinding to the transition layer or parent material welding, polishing smooth. The air was heated to 300C by oxyacetylene gun. Wear resistant welding strip in 200C for 1 hours. The local welding of the direct current and alternating current welding machine in 140-160A is carried out. The transition layer and surfacing layer are deposited first, and the wear resistant layer must be guaranteed 8~10mm.
