What is the principle of sand blasting machine?

The sand blasting machine uses the grinding fluid as the feeding power of the grinding fluid, and sends the evenly stirred grinding fluid (a mixture of abrasive and water) to the spray gun through the grinding fluid pump. As the acceleration power of grinding fluid, compressed air enters the spray gun through the air pipe. In the spray gun, the compressed air accelerates the grinding fluid entering the spray gun, and is ejected through the nozzle and sprayed onto the surface to be processed to achieve the desired processing purpose. In the liquid sandblasting machine, the grinding liquid pump is the feeding power, and the compressed air is the acceleration power.

What is the workflow of sand blasting machine?

Due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thus improving the fatigue resistance of the workpiece and increasing its adhesion between the coating and the coating prolongs the durability of the coating film. The sand blasting machine is also beneficial to the leveling and decoration of the paint, removing impurities, variegation and oxide layer on the surface, and at the same time roughening the surface of the medium, eliminating the residual stress of the workpiece and improving the surface hardness of the substrate.

What are the advantages of sand blasting machine?

1. The number and arrangement of shot blasting are calculated by computer shot blasting simulation. The 8 impellers are located up, down, left and right, respectively, to ensure that the shot blasting projectile covers most of the steel surface, including the ends. It ensures that the effect of shot blasting is comprehensive and effective.

2. The system of the sand blasting machine is a centrifugal hedging type shot blasting machine, which has the advantages of large blasting amount and fast ejection speed. The quantity and momentum of projectiles ejected to the surface of the workpiece in unit time are greatly improved. Therefore, the shot blasting time can be shortened, the efficiency can be improved, and a satisfactory cleaning quality can be achieved.

3. The dust removal system adopts filter type backwashing. The dust collector adopts a folded dust filter cartridge, which increases the dust removal area. The filter cartridge adopts nanofiber technology; the dust removal efficiency is over 99.99%, especially for dust particles with a diameter of 0.5μm. After high-efficiency filtration, the air is clean and can be recycled or discharged indoors. The pulse controller can adjust the frequency, speed and intensity of dust removal. Compared with the traditional domestic bag-type single-stage dust removal system, it has the advantages of high dust removal efficiency, small running resistance, small size, light weight and convenient replacement. Emissions comply with national emission standards.

●Precautions for the use of hydraulic jack

●How to repair and maintain hydraulic roof in daily use

Safe operation code of hydraulic jack

1. Hydraulic lifting equipment must be operated by specialized operators;

2. Ground wire must be installed for hydraulic pump station;

3. Check whether motor is rotating in pump indicated direction after startup; motor for this equipment is step-down startup with six second interval. Supply oil for jack after full start of the motor; exhaust air in system via exhaust valve before lifting;

4. Rated pressure for hydraulic system is 25Mpa and pressure indication of pump station pressure gauge cannot exceed 26Mpa;

5. Check clamp block of upper and lower clamps for slip during jack lifting. If block teeth are filled with foreign matters, clean on time and clean the taper sleeve outside block. Grease the taper surface to reduce sliding friction between taper surface and block arc; if teeth shaped surface is severely worn more than 0.4mm, replace block on time. Remove upper and lower clamps and clean after each project. Check wear condition and replace when necessary;

6. Check whether exhaust valve is closed before lifting;

7. Increase pressure slowly during adjustment;

8. System pressure can be at 28Mpa for a short time. Avoid long-term operation for damaging the system;

9. Do not crash high pressure oil pipe with hard objects. Avoid welding slag scorching. Replace high pressure rubber pipe for loss on time;

10. Release the pressure in system via exhaust valve when replacing hydraulic components;

11. Lift jack for a few millimeters when loosening clamp. Unload lower clamp and loosen it;

12. Loosen all lower clamps for butt joint and check; if looseness is inadequate, do not descend jack for opposite joint to avoid lower clamp damage;

13. Adjust pressure precisely when jack is ascending or descending in place. Do not put solenoid valve at neutral position to avoid instantaneous overvoltage;

14. Long-term overload operation is prohibited;

Precautions for the use of hydraulic jack

1. Hydraulic oil level in oil tank should be regularly maintained to normal level. Due to large capacity chamber of piping and hydraulic cylinder, it is mostly required to fill adequate hydraulic oil. After startup, hydraulic oil enters pipeline and cylinder, oil level decreases and filter even shows above oil level. Replenish hydraulic oil once again. It’s inevitable that hydraulic oil has loss during use, therefore, observe oil level regularly and replenish on time to maintain it at the middle position of level meter;

2. Hydraulic oil shall be kept clean always. Use oil filter vehicle when filling hydraulic oil with filtration precision below 30υm;

3. Replacing cycle for hydraulic coil is one year for normal operation;

4. Discharge all residual oil in tank when replacing hydraulic oil and refill after cleaning the tank. Filtration precision of new oil shall not be lower than precision of the system. Oil amount in tank shall be maintained within fixed level range;

5. Oil temperature shall be appropriate, not more than 60℃. Check for abnormal oil temperature rise. Start hydraulic pump and operate as required after oil temperature reaches 15 ℃ during winter;

6. Pay attention to the following for initial startup of hydraulic pump:

7. 1)     Hydraulic oil level in the tank shall be at the full position of vernier;

   2)     Check rotation direction of motor and it shall be clockwise seen from motor tail (arrow direction). If the direction id reversed, stop immediately and regain operation after handling;

   3)     Step up after 10 minutes’ idle operation of pump station;

8. Pay attention to check return oil filter. Replace cartridge for damage on time;

9. Before starting and stopping hydraulic pump, unload the overflow valve;

10. Spares for wear parts (seal ring, clamp block, etc.) shall be available at all times for timely replacement;

11. Set pressure of overflow valve cannot exceed maximum pressure of hydraulic system;

12. Check and maintain the jack before operation to ensure there is no oil leakage, clamp and the whole machine is in good condition;

13. When inserting lifting rod, the jack shall be loosened (loosening nuts at upper and lower clamps are screwed upward in place). Note that lifting rod and jack shall be almost concentric. Reset upper and lower clamps for normal operation and make the jack in operating state;

14. Prevent mud and sand from entering hydraulic rubber pipes during connection to avoid damaging hydraulic system and the jack;

15. Overpressure (overload) is prohibited during operation;

16. Lifting height shall exceed 20-30mm of coaming height and make jack piston at middle position for butt weld;

17. Make the jack at lifting state when descending the rod and oil pressure cannot be higher than that during lifting, that is to adjust oil pressure below that during normal lifting and then loosen lower clamp. After the jack is back stroke and lifted steel plate falls on newly surrounded plates, the jack bears no load. Loosen upper clamp and lifting rod descends;

18. According to actual ambient temperature, it is decided to use N46 anti-wear hydraulic oil for the system and mix of other grades is prohibited;

19. Clean and maintain the jack on time after one project, especially attachment at clamp block teeth. Replace for severe teeth wear and repair the replaced jack.

What are the reasons for using pipeline construction equipment

Due to the large volume of pipeline transportation, most of the pipelines are buried underground, occupying a small area, less terrain and object constraints, and short transportation distances.

Use pipeline construction equipment for sealed transportation, safe and reliable, long-term continuous and stable operation, easy to manage, easy to maintain, and realize remote centralized monitoring.

Therefore, a large number of pipeline laying work has been carried out in various countries, and related companies specializing in pipeline construction equipment have been derived. WINCOO is a company specializing in pipeline construction equipment.

What is the specific process of pipeline construction

There are many factors that can lead to operational defects in pipeline construction, such as inadequate installation technology, long construction period or insufficient supervision. Relevant technical personnel should be careful, careful, and concentrate on research and judgment when inspecting and accepting pipeline construction equipment.

Provide feedback and resolve the issue as quickly as possible. If the existing safety quality is not reached, the target area should be immediately compensated to ensure that the pipeline construction equipment can continue to operate safely. And maintain the original economic cost.

Specific process introduction:

Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair.

What pipeline construction equipment is needed during pipeline construction

The following pipeline construction equipment is needed during pipeline construction:

l Transport anticorrosive pipe

l Pipe assembly

l Pipe assembly and welding
