The maintenance and repair of large-scale hollow blow molding machine are two different maintenance methods for the equipment, but the purpose is one - hope that the production equipment can maintain good running state, ensure that the equipment can have high output and good products, and extend the working life of the machine and equipment as far as possible.
The maintenance of large-scale hollow blow molding machine is a regular work. The contents include: requiring the operators to use the equipment strictly and seriously according to the operation regulations of the large-scale hollow blow molding machine; operating production, cleaning and scrubbing equipment dust and oil and adding lubricating oil; inspecting and observing the operation of the machine, and asking the relevant personnel to eliminate the problems in time. This can delay the wear of machine parts and prolong the service life of the machine.
Equipment repair is to repair the damage of machine parts caused by normal or abnormal reasons. The purpose of repair is to restore the equipment to normal working capacity by repairing or replacing a part.
Attention should be paid to that maintenance and repair are equally important work. Maintenance is a protective measure for wear and damage of equipment parts. Repairing and replacing parts is a necessary means to ensure normal production and make equipment play its original performance. These two tasks should be well combined, focusing on prevention and taking precautions before they occur. Before the machine parts are damaged and can not work, it should be repaired and replaced in time to ensure that the machine has a good working condition for a long time.
Fixed sequence of blow molding machine equipment installation
The equipment foundation of blow molding machine should not only bear the weight of the equipment itself and the weight of raw materials for production, but also bear the dynamic load of automatic blow molding machine. The working speed of blow molding machine is not high and the dynamic load is not large, so there is no special requirement for its equipment foundation. Operate according to the basic condition requirements in the instruction manual of blow molding machine: use 300 or 400 cement, sand and stone to wash with water, and pour according to the mixing proportion of the three.
Installation and fixing sequence of foundation and equipment for large hollow blow molding machine.
① According to the instruction of plastic blow molding machine, dig the foundation pit, and dig the trench for wire conduit, upper and lower water pipe and compressed air pipe
② According to the distance size of the anchor bolt hole of the plastic blow molding machine, fix the wood mold of the anchor hole. The wood formwork for anchor hole shall be trapezoid or conical with small upper part and large lower part.
③ The pipelines for electricity, water and gas should be paved.
④ Pour the rod concrete and leave the anchor hole. The concrete should be covered with straw bags and watered twice a day after 24h. The ambient temperature should not be lower than 5 ℃,
⑤ After 7 days of cement curing, remove the foundation hole template, lift the blow molding machine and level it according to the position of the anchor hole; roughly find out the height, level and middle line position of the blow molding machine.
⑥ Place the equipment fastening bolt in the anchor hole, and screw the nut through the equipment foundation hole. Pay attention to set aside the length of thread for equipment height adjustment.
⑦ The foundation hole shall be poured with concrete and the curing period shall be more than 10 days.
⑧ A pair of inclined iron plates (with a slope of 1 / 20-1 / 10) and a steel plate are used as a group: the steel plate is under, and a pair of inclined iron plates are placed on the steel plate in the opposite direction, and are padded on both sides of the anchor bolts. At the same time, correct the screw middle line of blow molding machine coincides with the equipment middle line of blow molding machine production line
⑨ The bolts and nuts should be pre tightened diagonally and the tightening force should be balanced.
Correct the level, middle height and middle line position of large hollow blow molding machine. Tighten all the foot bolt holes. Connect water, gas and electrical lines.
