Under normal circumstances, the regular maintenance of large-scale hollow blow molding machine equipment is once a year. The time is usually arranged in the days before the holidays or during the holidays. The equipment management personnel participate in the guidance work, and the equipment maintenance workers and operators cooperate. The main contents of regular maintenance of the equipment are as follows:
① Clean and scrub the oil stains and dust in the electric control box of the large hollow blow molding machine;
③ Remove the gearbox and bearing gland, check the quality of lubricating oil and the amount of metal powder in the oil, and clean and replace the oil if necessary;
③ Check the wear condition of various transmission parts. The gear with serious wear shall be surveyed and prepared to be replaced in the next maintenance;
④ Check the wear of the belt in the V-belt drive and adjust the tightness of the V-belt installation. Replace the seriously worn V-belt;
⑤ Check the wear condition of barrel and screw. For slight scratch and rough surface, polish it with oilstone or fine sand cloth, and record the measured size of cylinder and screw working surface;
⑥ Record the model and specification of V-belt and bearing with serious wear, put forward the order plan of damaged parts after maintenance, and prepare to replace it at the next maintenance;
⑦ Check and correct the difference between the heating temperature of the barrel (measured by mercury thermometer) and the temperature displayed by the instrument to ensure the correct operation of the extrusion process temperature;
⑧ Adjust and test each safety alarm device to verify its reliability and accuracy;
⑨ Test and check whether all kinds of pipelines (water, air and lubricating oil) are unobstructed, and repair the leakage and blockage parts,
⑩ Check and adjust the position of electric heating device, cooling fan and safety cover to ensure that they can work normally and effectively.
What are the business contents of the maintenance of large hollow blow molding machine
What are the business contents of the maintenance work of large hollow blow molding machine equipment
The maintenance work of large-scale hollow blow molding machine is based on the wear condition of some parts found in the equipment maintenance and the equipment problems affecting the product quality in the production work. The equipment technicians decide to repair or replace some parts or parts in a planned way, so as to restore the good working condition of the equipment.
The maintenance work of large-scale hollow blow molding machine can be divided into normal maintenance arranged according to the work plan and the maintenance of unexpected accidents in normal work.
