Repair vertical injection molding machine Overview

Usually vertical injection molding machine may cause after being flooded with varying degrees of water inside the electrical control box electrical, machine hydraulic systems, lubrication systems, in this case, can be divided into the following sections to analyze the process:

First, the vertical injection molding machine electrical control part

After the vertical injection molding machine electrical parts water, it can cause a variety of electrical insulating properties of the original rust corrosion and reduce the phenomenon. General Press Follow these steps:

1. Disconnect all power;

2, in the shortest possible time after flooding, the I / O PC board above the battery is removed (recommended customers timely action) because the I / O board in the case of the battery is not removed, the individual components is still powered, This will accelerate rust and corrosion extent these elements, will increase the difficulty of component repair and maintenance costs;

3, the whole point of the electrical components inside Remove the (service operation) cleaning with alcohol, it is necessary if you want to break down the parts cleaning, including the I / O board, 24V power supply, 5V power supply, transformers, AC contactors, air switches, axial fans and the like;

4, and dried using the drying hopper will all live components sufficiently dried, the cleaning element can be decomposed into hierarchical clean, after drying hopper and dried at a temperature of 50 ~ 70 ℃, drying time of 8 to 10 hours, to test the insulation resistance value Meets requirements (generally measured by 200K file), it is determined whether or not completely dry;

5, the dried completely separate power check electrical components (service operation), the check can only be installed using intact.

Second, the vertical injection molding machine hydraulic part

1, can not open the vertical injection molding machine motor pump, because the motor is turned back into the hydraulic oil in the water may enter the hydraulic piping system of the machine, causing corrosion of metal hydraulic components;

2. Check the hydraulic fluid is water. Open the plug on the rack at the bottom of the tank, and release a small amount of oil, with a piece of paper stained with a little light, if you can not ignite a fire burning in the process of crackling Baoxiang, then the hydraulic oil in the water, we need to replace the entire hydraulic oil. (Anhydrous copper sulfate can also be used to test whether or not becomes blue, then the blue water);

3, if the water content in the oil, replace the fuel tank of hydraulic oil. Before oil change use a clean cloth to wipe the tank;

Third, the other part of the vertical injection molding machine

1, the motor of the motor stator and a rotor separated from the stator winding drying process (process that allows professional repair motor can also be used in the motor housing 100W incandescent thorough drying processing approximately 8 hours), insulation resistance must ensure ≥0.4 MΩ, the motor bearings removed by cleaning after checking whether the use of gasoline, are then replaced with the specifications bearings;

2, the lubrication pump

The lubrication pump rotor, a stator and a pump bile separation, fixed set of windings can be used for drying the drying hopper, the insulation resistance must ensure ≥0.4MΩ, pump gall rust stuck if you can die rust remover spray of bile into the pump inside rust, gear pumps can be flexible rotation within the bladder.

3, sub-size model must take the connector plug, connector socket (air plug) separately, dried (hair dryer available) after cleaning.

Fourth, the vertical injection molding machine servo motor and control system

1, electrical components, circuit board first with alcohol and then wash it off with a dry wind dried for 24 hours in 55 ℃ oven or drying hopper.

2, the vertical injection molding machine servo motor encoder and drying attention and motor bearing protection motor stator to prevent rust.

After the above ministries processed, re-assembled parts, power test machine.
