Skeye Machinery Co., Ltd. Granite Components

 1. Cleaning and cleaning of good parts. The cleaning work includes the removal of residual foundry sand, rust, chips, etc. Especially some important parts, such as the gantry cutting machine, the inner cavity should be painted with anti-rust paint. Oil stains, rust or attached cuttings on the parts can be cleaned with diesel, kerosene or gasoline as a washing liquid, and then dried with compressed air.

 

  2. Lubricant is usually added to the mating surface before mating or connecting. Especially the bearing part in the spindle box component, the screw nut part of the lifting mechanism.

 

  3. The matching dimensions of the matching parts should be accurate, and the matching dimensions should be re-inspected or spot-checked during assembly. For example: the matching part of the main shaft journal and the bearing, the matching hole of the main shaft box and the bearing and the center distance.

 

  4. The assembly of the wheels requires that the axis lines of the two toothed wheels must be in the same plane and parallel to each other. Normal toothing clearance should be ensured, and the axial misalignment should be ≤2MM.

 

  5. The joint surface of the joint should be checked for smoothness and deformation. Otherwise, it should be trimmed and burrs removed to ensure that the joint surface is in close contact, flat, and not skewed.

 

  6. ​​The seals should be pressed into the sealing groove in parallel, and they should not be twisted or deformed, and the sealing surface should be damaged or scratched.

 

  7. The assembly requirements of the pulleys are that the axes of the two pulleys must be parallel, and the center of the groove should be positive. Excessive deviation will cause uneven tension of the pulleys, resulting in belt slippage and accelerated wear. At the same time, the V-belt should be selected before assembling, and the length should be consistent to prevent vibration in the transmission.

 

8. The bearing should be cleaned before assembling, and the anti-rust paint should be washed off before assembling. When cleaning, check whether the raceways and rolling elements are corroded and whether the rotation is flexible; when assembling the bearing, apply a layer of lubricating oil on the surface of the mating parts. When the pressure difference is too large, the assembly should be stopped for inspection; when assembling the bearing, the end without the model should face inward, in the direction of the shaft shoulder; when the bearing is set, the direction and position of the afterburner should be appropriate, and the raceway should not be rolled. The body should be struck evenly and symmetrically without slamming. Ensure that the end face is perpendicular to the shaft to prevent the installation from tilting.

 

9. The threaded connection should adopt the anti-loosening device. According to the actual situation and design requirements, the following commonly used anti-loosing devices should be selected; double nut anti-loosing; spring washer anti-loosing; split pin anti-loosing; stop washer anti-loosing round nut and flower cushion anti-loosing ; The tightening method of symmetrical multiple bolts should be tightened gradually in a symmetrical sequence, and the strip connectors should be tightened symmetrically from the middle to the two directions. The end of the rib of the bolt connection should protrude from the nut.

(1) The stomata bai rate is high. The important feature of porous ceramics is that they have more uniform and controllable pores. The pores are divided into open pores and closed pores. The open pores have the functions of filtering, absorbing, adsorbing, and eliminating echoes, while the closed pores are good for blocking heat insulation, sound, and the transmission of liquid and solid particles.

(2) High strength. Porous ceramic materials are generally made of metal oxides, silicon dioxide, silicon carbide, etc., which are calcined at high temperatures. These materials themselves have high strength. During the calcination process, the boundary of the raw material particles melts and bonds, forming a high

Strong ceramics.

(3) Stable physical and chemical properties. The porous ceramic material can withstand acid and alkali corrosion, and can withstand high temperature and high pressure. It is in a good clean state and will not cause secondary pollution. It is a green and environmentally friendly functional material.

(4) High filtration accuracy and good regeneration performance. The porous ceramic material used as the filter material has a narrow pore size distribution range and a higher porosity and specific surface area. The filtered material is in full contact with the ceramic material, and the suspended solids, colloids, microorganisms and other pollutants are blocked in the filter. Good filtering effect on the surface or inside of the medium. After a period of use, the porous ceramic filter material can be backwashed with gas or liquid to restore the original filter capacity.
