Motor use and maintenance:
Motor use and maintenance are often overlooked by people, whether a motor can maximize the economic benefits, extend the service life, the proper use and routine maintenance is a key issue.
(1) Start-up: The motor should first be checked before starting mechanical aspects, such as checking whether the shaft is flexible; bearings should be properly lubricated; fan and hood can not collide, the motor base fixed rate. Then you must check the circuit, plus check the motor leads are connected. Some motor outlet box only two lines, this easy access, and some have four lines, then the manual must be connected according to the instructions, otherwise it will burn out the motor. Thread must be firmly connected; the best in the motor outlet before installing a fuse, fuse ampere quota should be higher than the motor ampere quotas about 10 to 25%.
Before running the motor, it is best to carry out no-load test with no load, check whether the rotation is normal, whether the steering meets the requirements and so on. Single-phase motor steering. Manufacturers have taken the winding, not easy to change.
The motor starts normally 3 ~ 5 seconds to start is completed, if more than this time the motor can not turn up or reach less than 70 ~ 80% of the rated speed, you should quickly cut off the power, check the cause of the malfunction, must not be delayed, or easy to burn out Winding. This situation may be overloaded; the voltage is lower. Centrifugal switch does not move, motor windings and so on.
(2) Operation: When the motor runs normally with load, the speed is uniform, the sound is moderate, and the heat is proper. However, we should always pay attention to the motor temperature rise, if serious fever and other adverse symptoms must be closed to stop running. Mostly in rural areas as a result of grid voltage drop, this kind of heat does not burn the windings for a while, but to reduce the service life of the motor. To ensure that the motor moisture and good ventilation, the outlet box and capacitors, etc. can not enter the water, there is no mechanical damage. Wind shield can not be blocked, the motor housing should be well grounded. Capacitor damage update, the new capacitor voltage value of not less than the voltage of the old capacitor, the number of its approach is best equal.
(3) Maintenance: motor running for a long time can be opened for maintenance. Clean up debris inside the debris, add the lubricating oil (with sodium calcium base grease No. 1); preferably with 500-volt shake table winding insulation resistance measurement, the normal should be not less than 0.5 megohm.
Disassembly should pay attention to: â‘ winding wiring, centrifugal switch welding point shall not be wrong or disconnected, â‘¡ are not allowed to touch the winding insulation, protect the centrifugal switch clearance, to ensure the normal operation of its contacts, the contact Burning sparks can be fine polished cloth gently polished. â‘¢ aluminum shell motor should pay attention to avoid heavy blows, protect the end face of the motor stop, do not damage the chassis, the cover of the cooling ribs to maintain good cooling conditions. Fan blades can not touch the touch off, the bearings and shaft may not have mechanical damage and so on. When the motor is stored, it should be placed in ventilated and dry place.
Thermoforming packaging containers, such as cups, boxes, bowls and other thin-walled containers, such as milk cups, jelly cups, ice cream cups, disposable drinking cups, instant noodle bowls, fast food boxes, etc.
It is suitable for moulding plastic sheets such as HIPS, PS, PP, PVC, PET, ABS, etc. It can process high transparency, high tension, shallow tension, round, square, irregular, up and down biaxial tension, flanging and other products, and produce various packaging products such as boxes, plates, trays, bowls, caps and industrial packaging products.
The equipment is mainly composed of body, plastic absorption forming system, temperature control system, vacuum system, heating system, gas control system, electrical and computer control system, finished product punching system, product decomposition and self-winding system.
