How to replace and install the hydraulic oil of the thread rolling machine?

Z28-150 thread rolling machine

√ The important thing about the thread rolling machine is to ensure the pressure is stable, and the first condition to ensure the pressure is the quality of the hydraulic oil. Many users have experienced pressure changes when the hydraulic oil has just been replaced, and the pressure will not be met soon. To eliminate the increase in oil temperature caused by weather, you should focus on checking the quality of hydraulic oil. Some users have reported that they have just changed the hydraulic oil. In fact, there is a misunderstanding here. First of all, you changed the oil but you are not qualified for the hydraulic oil. Secondly, Is the correct method for you to change?

√ The correct replacement method should drain the long oil, manually return the solenoid valve back to the valve core, and return the oil in the pipeline to the fuel tank. After draining, wipe the inner wall of the fuel tank with a clean rag to remove the old oil. Precipitated oil slag ensures cleanness in the fuel tank. For models with return oil filtration system, the oil return filter should also be removed and cleaned.

√ Old oil removal is not completely mixed with new oil, it will quickly pollute new oil and reduce the performance of hydraulic oil. Long-term use of unqualified hydraulic oil will also cause irreparable damage to solenoid valves and hydraulic oil pumps. Be careful when using a thread rolling machine to avoid unnecessary losses.

√ In order to make the thread-rolling machine have better effect when used, there are many aspects to be aware of when installing. So what do you need to pay attention to?

1. The important thing of the rolling machine is to ensure the pressure is stable, and the first condition to ensure the pressure is the quality of the hydraulic oil. Many users have experienced pressure changes when the hydraulic oil has just been replaced, and the pressure will not be able to meet the requirements. To eliminate the increase in oil temperature caused by weather, you should focus on checking the quality of hydraulic oil. Some users have reported that they have just changed the hydraulic oil. In fact, there is a misunderstanding here. First of all, you changed the oil but you are not qualified for the hydraulic oil. Secondly, is the correct method for you to change?

2. Turn on the electrical box equipment and carefully check if all the terminals inside are loose. If you find the problem, tighten them immediately. The hydraulic thread rolling machine supplier reminds you that you need to check the status of the wires to ensure that the wires are complete and there will be no problem of broken skin. When problems are found, they should be replaced in time.

3. During the test run after the power is turned on, it is necessary to pay attention to the operation of the hydraulic motor, and ensure that it is in a clockwise rotation state. In addition, the cooling water pump is also a very important component. If the coolant is reversed, the coolant will not come out, or it will come out very little. The main motor can be disregarded. It is determined according to the workpiece and the selection switch of the rolling mold used on the panel to rotate to the left or to the right. If the phase sequence is wrong, just leave the power cord free. Just switch the two random phase lines in the power cord.
