OEM Screw Air Compressor Oil Separator Air Filter Oil Filter Supplier, Suppliers

Air filter The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the screw rotor compression chamber for compression. Due to the internal clearance of the screw machine, only particles within 15u are allowed to filter out. If the air filter element is clogged and damaged, a large number of particles larger than 15u will enter the screw machine and circulate, which will not only greatly shorten the service life of the oil filter element and oil-gas separation core, but also cause a large amount of particles to directly enter the bearing cavity, which will accelerate bearing wear and increase the rotor clearance. The compression efficiency is reduced, and even the rotor is dry and seized.

Air Filter

The air filter is a component that filters out air dust and dirt, and the filtered clean air enters the screw rotor compression chamber for compression. Due to the internal clearance of the screw machine, only particles within 15u are allowed to filter out. If the air filter element is clogged and damaged, a large number of particles larger than 15u will enter the screw machine and circulate, which will not only greatly shorten the service life of the oil filter element and oil-gas separation core, but also cause a large amount of particles to directly enter the bearing cavity, which will accelerate bearing wear and increase the rotor clearance. The compression efficiency is reduced, and even the rotor is dry and seized.

Oil Filter

After the new machine runs for 500 hours for the first time, the oil filter element should be replaced. Use a special wrench to reverse the oil filter element to remove it. It is best to add screw machine coolant before installing the new filter element. Screw the filter element back to the oil filter seat with both hands and tighten it firmly. It is recommended to replace the new filter element every 1500-2000 hours. It is best to replace the oil filter element at the same time when changing the coolant. When the environment is harsh, the replacement cycle should be shortened.

Warning: It is strictly forbidden to use the oil filter element beyond the time limit, otherwise, due to the serious clogging of the oil filter element, the pressure difference exceeds the tolerance limit of the bypass valve, the bypass valve will automatically open, and a large amount of dirt and particles will directly enter the screw host with the oil, causing serious consequences.

Oil Separator

The oil-air separator is a component that separates the cooling liquid of the screw machine from the compressed air. Under normal operation, the service life of the oil-air separator is about 3000 hours, but the quality of the lubricating oil and the filtration accuracy of the air have a huge impact on its life. It can be seen that the maintenance and replacement cycle of the air filter element must be shortened in harsh operating environments, and even the installation of a front air filter must be considered.

The oil and gas separator must be replaced when it expires or the pressure difference between the front and back exceeds 0.12Mpa. Otherwise, the motor will be overloaded, and the oil-air separator will be damaged and oil will leak out.

Replacement Method: Remove the control pipe joints installed on the oil and gas barrel cover. Take out the oil return pipe extending into the oil and gas barrel from the cover of the oil and gas barrel, and remove the fastening bolts of the upper cover of the oil and gas barrel. Remove the upper cover of the oil and gas barrel, and take out the oil. Remove the asbestos pad and dirt stuck on the upper cover. Install a new oil and gas separator, pay attention to the upper and lower asbestos pads must be stapled and stapled, and the asbestos pads must be placed neatly when pressing, otherwise it will cause pad flushing. Reinstall the upper cover plate, oil return pipe, and control pipes as they were, and check for leaks.

Coolant Replacement

The quality of the screw machine coolant has a decisive impact on the performance of the oil-injected screw machine. A good coolant has good oxidation stability, rapid separation, good foam cleaning, high viscosity, and good anti-corrosion performance. Therefore, users must use Pure screw machine coolant. The first coolant should be replaced after 500 hours of running-in period of the new machine, and the coolant should be replaced every 3000 hours of operation thereafter. It is best to replace the oil filter at the same time when changing the oil. Use in places with harsh environments to shorten the replacement cycle.

Replacement Method: Start the air compressor and run it for 5 minutes, so that the oil temperature rises above 70°C and the viscosity of the oil decreases. Stop running, when there is a pressure of 0.1Mpa in the oil and gas barrel, open the oil drain valve at the bottom of the oil and gas barrel, and connect the oil storage tank. The oil drain valve should be opened slowly to prevent the coolant under pressure and temperature from splashing and hurting people and dirt. Close the oil drain valve after the coolant is dripping. Unscrew the oil filter element, drain the coolant in each pipeline at the same time, and replace with a new oil filter element. Open the screw plug of the oil filler, inject new oil, make the oil level within the range of the oil scale, tighten the screw plug of the filler, and check for leakage.

Frequently Asked Questions

Q1: How often should the compressor oil filter be replaced?

For a new machine, the oil filter element should be replaced after the first 500 hours of operation. Subsequently, it is recommended to replace the oil filter element every 1500 to 2000 hours. The replacement cycle should be shortened under harsh operating environments.

Q2: What happens if the oil filter element is used beyond its service life?

If used beyond the limit, serious clogging will occur, causing the pressure difference to exceed the bypass valve's tolerance limit. The bypass valve will then open automatically, allowing a large amount of dirt and particles to enter the screw host directly with the oil, which can cause severe component damage.

Q3: What is the typical service life of an oil-air separator?

Under normal operating conditions, the service life of an oil-air separator is approximately 3000 hours. However, this is highly dependent on the quality of the lubricating oil and the filtration efficiency of the air filter.

Q4: When should the air compressor coolant be replaced?

The first coolant replacement should take place after the 500-hour running-in period of a new machine. Thereafter, it should be replaced every 3000 hours of operation. It is highly recommended to replace the oil filter element simultaneously when changing the coolant.

Q5: Why is mixing different brands of coolants prohibited?

Mixing different brands of coolants is strictly forbidden because it degrades the quality of the coolant. This leads to poor lubrication, a lowered flash point, and increases the risk of high-temperature shutdowns or spontaneous combustion of the oil.

Q6: What are the main benefits of a high-quality oil separator element?

A high-quality separator element offers high porosity, excellent permeability, low pressure drop, and a large flow rate. It also provides high dust holding capacity, high filtration accuracy, and reliable corrosion and high-temperature resistance.
