Today, Rongwei Machinery Technology Co., Ltd. will analyze hydraulic oil pollution for customers.
Harmfulness of hydraulic oil pollution of NC bending machine
The heavy pollution of automobile oil will immediately endanger the characteristics of hydraulic transmission system. What's more, it will cause frequent faults of the braking system and reduce the service life of the hydraulic bending mechanism.
The specific reason for this risk is the particles in the dust. As far as the hydraulic mechanism is concerned, the liquid particles entering the component will lift the component and drag the component to damage. In addition, it will also block the throttle valve hole, the damping hole in the hydraulic parts or the valve core is stuck, resulting in abnormal hydraulic press system.
In addition, the mixing of water and gas reduces the lubrication of hydraulic oil, accelerates the air oxidation of hydraulic oil, and causes cavitation erosion. Therefore, the accelerated etching of hydraulic parts will cause vibration, noise and so on.
Countermeasures to avoid hydraulic oil pollution of NC bending machine
In order to increase the service life of components of the hydraulic transmission system, ensure the reliable operation of the hydraulic transmission system, and make it feasible to control the hydraulic oil pollution within the necessary range.
There are two levels as follows:
First, it is necessary to avoid the pollution source entering the hydraulic transmission system. In addition, it is necessary to remove the pollution source already entering the system.
In addition, pollution control shall focus on all links, including design concept, production, manufacturing, installation, application, maintenance, overhaul, etc. of hydraulic device.
To avoid pollution, the NC bending machine adopts the following countermeasures in specific work:
Always keep the hydraulic press clean before use
Hydraulic oil is very easy to be polluted in the whole process of transportation and storage. The newly bought hydraulic oil looks neat, but in fact it's very dirty. Be sure to let it stand for a few days, and then consider its application in the hydraulic transmission system.
Always keep the oil clean after equipment and before operation
The automobile oil tank of NC bending machine must be clean in the whole process of production and manufacturing. In addition, the hydraulic transmission system should be completely clean after assembly and operation. Therefore, after the production, manufacturing and assembly are carried out and the test run is passed, people will remove the hydraulic oil in the and before the hydraulic oil is transported to the customer. That can ensure that the hydraulic oil is not easy to leak or pollute in the whole process of transportation. After the equipment is delivered to the customer, teach the customer to install, add hydraulic oil and operate the equipment again.
Keep clean during work
In the whole application process of NC bending machine, the hydraulic oil will be polluted by air, so people should prevent the invasion of gas and water. In order to completely solve the invasion of water, gas and pollution sources, a completely sealed water storage tank must be used. Lift the air filter screen on the vent to prevent dust, wear-resistant materials and refrigerant from entering. However, customers still have to maintain and replace hydraulic seals regularly.
Use a suitable oil filter element.
It is a specific way to control hydraulic oil pollution. Technical manufacturers will select different filtering methods, different precision and different filter device structures according to the provisions of machinery and equipment. Friends, customers must regularly maintain and clean the engine oil filter element and automobile fuel tank.
Replace the hydraulic oil on time
After a lot of research, many customers have hardly replaced the hydraulic oil in order to be cost-effective. As a result, the equipment is seriously damaged and even unable to work. Be sure to maintain and replace the hydraulic oil regularly. Be sure to clean the vehicle oil tank before introducing new oil.
Controls the temperature of the hydraulic oil
Too high operating temperature of hydraulic oil is harmful to hydraulic device. In addition, high temperature will also accelerate the mildew of the oil itself, cause different products and reduce its service life. Generally, the operating temperature of all hydraulic transmission systems is preferably less than 65 ℃. The hydraulic transmission system of NC bending machine shall be operated below 55 ℃.
