The no-load test has the following requirements:
(1) Start and stop according to the start-up procedure, and all relevant chain systems should meet the technical requirements;
(2) The moving cone rotates in the forward or reverse direction (rotation) and should not exceed 15 revolutions per minute.
(3) The bevel gear should have no impact and periodic noise.
(4) The lubrication system works normally. The oil supply pressure should be in the range of 0.5-1.5 kg/cm 2 and the return oil temperature should not exceed 50 ° C (the load test should not exceed 60 ° C).
(5) The hydraulic adjustment device of the hydraulic equipment shall be locked according to its operating procedure; the size of the discharge port shall be adjusted to meet the requirements for use.
(6) The normal continuous operation time should not be less than 2 h, generally to meet the identification requirements.
The load test has the following requirements:
(1) Perform a load check on the items inspected in the no-load test run.
(2) Load test time, it is necessary to run normally for two days and nights (allow short-term parking check). The ore should be gradually increased, and the first amount should be fully loaded.
(3) The ore position should be installed correctly, and the ore should be evenly distributed in the crushing chamber.
(4) In the absence of over- iron , the support sleeve should not be bounced, and it can be smoothly eliminated in the case of over-iron.
(V) in the normal crusher crushing process, there should be no sharp vibration and abnormal sound.
A blended powder of tungsten carbide and Metal Alloy Powder can be used for laser cladding, a process used to deposit a layer of material onto a substrate using a laser beam. This blended powder is typically used as a feedstock material for laser cladding applications where high wear resistance and hardness are required.
Tungsten carbide is a hard and wear-resistant material that is commonly used in cutting tools, mining equipment, and other high-wear applications. It has excellent thermal conductivity and high melting point, making it suitable for laser cladding processes.
Metal alloy powders, on the other hand, are often added to the Tungsten Carbide Powder to enhance certain properties or tailor the characteristics of the final cladding layer. These metal alloys can include nickel, cobalt, chromium, or other elements, depending on the specific requirements of the application.
The blended powder is typically prepared by mixing the tungsten carbide and metal alloy powders in the desired ratio. This mixture is then fed into a laser cladding system, where it is melted using a high-power laser beam. The molten powder is rapidly solidified onto the substrate, forming a dense and wear-resistant cladding layer.
The resulting cladding layer can have excellent hardness, wear resistance, and thermal conductivity, making it suitable for various applications such as tooling, wear parts, and surface protection. The specific properties of the cladding layer can be adjusted by varying the composition and ratio of the tungsten carbide and metal alloy powders in the blend.
Overall, the blended powder of tungsten carbide and metal alloy powder offers a versatile and customizable solution for laser cladding applications, providing enhanced wear resistance, hardness, and other desired properties to the final cladding layer.
