Since the 30kw rotary screw air compressor rotor rotates in the barrel, the lubricating oil and the compressed air rub against the screw and the body. So that the working surface of the screw is gradually worn. The diameter of the screw is gradually reduced. And the diameter of the inner hole of the 30kw 40 hp screw air compressor is gradually increased. In this case, the gap between the screw and the 30kw screw air compressor’s mating diameter increases a little with the wear of the 40 hp screw air compressor rotor. Email:info@fntcompressor.com

Since the resistance of the front part of the air compressor screw 40hp machine and the manifold is not changed, this increases the leakage flow when the air is pushed forward. That is, the flow of air and lubricating oil from the diameter gap to the intake direction increases. And the time is long, slowly the air compressor screw rotor will wear out.

So, the question is, how do we fix the 30kw air compressor screw rotor wear of the 40 hp screw air compressor? The KINGBULL rotary screw air compressor is described as follows.

First, the 30kw rotary screw air compressor machine body repair

The inner surface of the 40 hp screw air compressor is harder than the screw. Its damage is later than the screw. The scrapping of the 40 hp screw air compressor is the diameter of the inner diameter, which wear will increase due to using time. The repair method is as follows. Email:info@fntcompressor.com

Because the wearer increases the diameter of the air compressor screw 40hp body. If there is a certain layer of nitrided, the diameter of the hole in the 30kw rotary screw air compressor can be bored, ground to a new diameter. Then the new screw is prepared according to the diameter.

The inner diameter of the 30kw rotary screw air compressor machine body is machined and trimmed to recast the alloy, the thickness is between 1-2mm, and then finished to the size.

Second, screw air compressor screw repair

The broken screw should be considered according to the actual inner diameter of the 30 kw air compressor screw. The outer diameter deviation of the new screw is given according to the normal gap of the screw air compressor 30 kw. Email:info@fntcompressor.com

After the surface of the thread with the reduced diameter of the wear screw is treated. The wear-resistant alloy is thermally sprayed and then ground to size. This method is generally processed and repaired by a professional spray factory. At the same time, the cost is still relatively low.

Surfacing the wear-resistant alloy on the threaded portion of the wear screw. Depending on the degree of wear of the screw, weld 1 to 2 mm thick and then grind the screw to size. This wear-resistant alloy consists of materials such as C, Cr, Vi, Co, W and B. Which increases the anti-wear and corrosion resistance of the screw. Professional butt welders have a high cost for this type of processing, and are rarely used except for special requirements.

The repair screw can also be plated with hard chrome. Chrome is also a wear-resistant and corrosion-resistant metal, but the hard chrome layer is easier to fall off.

In the above, KINGBULL brand 40hp rotary screw air compressor introduced how to repair the rotor wear of the screw air compressor.
