Production
Bushings
Bimetallic cylindrical bushings are manufactured according to the latest advanced technologies by centrifugal casting.
The developed high-tech process allows to obtain the working surface of the bushings with high technical performance,
due to bulk alloying of the product. In the manufacture of bushings for alloying, molybdenum, nickel, and chromium are used.
Special hours-long hardening and a high content of alloying components on the working layer, allows you to get products with a resource from 600 to 800 hours.
This exceeds at least 2 times the guaranteed resource of bushings made by standard technology of steel grade Steel 70.
The basic process for manufacturing bimetallic bushings
The basic process for manufacturing bimetallic bushings
The manufacture of bimetallic bushings occurs by centrifugal casting, under certain conditions,
a high content of alloying, hard alloy components is created on the future work surface. As a result, the hardness of the working surface increases to 65-70 NKS,
which determines the increased operating time. Since bimetallic bushings are not completely made of an expensive alloy during production, their cost slightly increases.
The casting process takes place in a monolithic mode, bimetallic bushings have a high density and the absence of seams.
Centrifugal casting allows you to get a high quality product and reduces possible manufacturing defects to a minimum.
An additional high-frequency hardening normalizes bimetallic tubes, relieves stress and improves their performance, increases hardness.
Advantages of bimetallic bushings comparing a bimetallic bush with a standard bush, its resource is increased up to 2, 3 times.
This is justified by the high hardness of the inner working surface of bimetallic tubes manufactured for mud pumps.
There is also the possibility of reusing a bimetallic sleeve, which has already developed its guaranteed resource.
For this, the sleeve is simply subjected to turning, as a result, slightly increasing the internal working diameter, it can be reused.
That is, as a result, the bimetallic cylinder sleeve can have a total service life of up to 3, 4 times higher than standard, single-component bushings.
Valves
The mud pump valve is designed to alternately communicate and disconnect the pump chambers with the suction and discharge pipelines in the flushing fluid medium. The design feature of the valves: the seal occurs between rubber and metal, and the valve disc does not sit (does not hit) on the seat crosspiece. This design of the mud pump valve allows to increase the mean time between failures compared to the conventional design by 10-15%.
Vibrating screen cassettes
The rigid sieve cassette on a plastic basis is the same two nets fastened with a plastic grate, but this grate is made in the form of a rigid frame with a thickness of about 40 mm. Such a cartridge does not need tensioning devices, since the mesh on it is stretched in advance when the cartridge is manufactured. On a vibrating screen, such a cassette is attached with simple wedges or clamps. A rigid metal-based cassette differs from a plastic-based cassette in that the frame of such a cassette is not made of plastic, but of metal, and the molten plastic fastens both nets and a metal frame with nets.
