When using injection molding machine
in a factory, we must be regular maintenance and maintenance, so as to the service life of the injection molding machine, the growth of more can save costs for the enterprise, so, in the vertical injection molding machine filters and the bypass oil filter replacement and cleaning, we should how to do?
Next by vertical injection molding machine manufacturer to introduce you to some of the filter and the bypass oil filter replacement and cleaning method.
Vertical injection molding machine filter for oil suction filter, installed in the pump inlet on the side of the tank, used to filter, clean the hydraulic oil.
When removing and replacing filter core, should follow the following instructions.
Some oil filter is put in the tank, cleaning, and then clean the filter directly to tear open come out.
1, use and maintenance according to the experiment and research results show that the fault of hydraulic equipment for more than 80% are caused by the pollution of oil, in consideration of the oil cleanliness requirements, the machine to install the bypass oil filter, suitable for high cleanliness requirements of the machine installation to avoid oil contamination, reduce mechanical wear and failure.
The longer the machine running time, the oil pollution is more serious.
Oil filter is through its internal filter oil filter effect, must be replaced after a certain period of time, the running of the machine for oil filter can work normally.
The lower oil filter is equipped with pressure gauge, allowable pressure rating of the filter is 0.
5 mpa, in the running of the machine, when the pointer of the table is smaller than 0.
5 mpa, said filtering situation is normal, when table pointer is greater than zero.
5 mpa, said filter blockage, users should replace filter, so as not to affect the normal work of the oil filter, ultimately affect the normal operation of the machine.
When replacement filter, machine should stop working, and will filter the handles on the lid off after the lift, and then pull out the filter, change a new filter, as is tight after installation, you can start work.
2, remove the first down the fuselage side boards, unscrew the filter in the middle of the socket head cap screw, oil filter and oil in the tank is separated, and then twist the end cover socket head cap screw, take out the filter, and then open it separate the filter and the middle bar.
3, clean thoroughly with light oil, gasoline, or washing oil removal filter blocking all the dirt on the wire, and all the metal on the magnet in the middle.
Insert the compressed air from the inside, and dirt from the wire.
In 4, install the filter in the filter, to tighten the Allen screw in end cover and tighten the Allen screw in the middle.
5, pay attention to (1) when the oil filter to remove, do not start hydraulic pump motor.
(2) when using compressed air blowing, cannot make blow air pump fixed too tight.
(3) if the wire is damaged, be sure to replace filter.
(4) in the dismantling and installation, must be careful so as not to damage the wire.
(5) after installing filter core, before starting motor, must look for screw down the middle socket head cap screw.
6. After the installation of the filter priming pump motor and oil pump light work ten minutes, after the oil pump normal work load.
6, oil change oil change can use barrel oil pump or siphon device, from the mouth filling vacuum oil absorption from the fuel tank.
The rest of the residual oil by the discharge of oil on the tank mouth out, therefore, is located in the bottom of the tank of oil discharge bolt must be turned on.
Foreign body in the empty tank.
At the same time also want to empty oil cooling unit and oil.
Any old oil, residual oil can lead to accelerated aging of new oil.
Open the side cover plate and tank top cover plate, all the foreign body in empty tank, such as oil filter is installed in the tank, at the same time, remove the oil absorption, oil filter, wash tank.
Change oil suction filter, rotary oil discharge bolt, sealed cover plate, filled with hydraulic oil.
Pollution control: must dispose of used oil.
Used oil suction filter, can return to oil suppliers, etc.
Oil filter can be recycled.
