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.

l The tank hydraulic jacking system is classified according to the standard of walking mechanism.

l Tank hydraulic jacking system classified according to structural characteristics standards.

l The tank hydraulic jacking system is classified according to the standard of the tower structure rotation mode.

 

The tank hydraulic jacking system is classified according to the standard of walking mechanism.

It can be divided into mobile tank hydraulic jacking system and fixed tank hydraulic jacking system.The mobile tank hydraulic jacking system can run on a special track, has good stability, can walk with load, and has high work efficiency, so it is widely used in construction and installation projects.

 

The fixed tank hydraulic jacking system is divided into two types: attached jack-up type and inner-climbing type according to the different installation positions. The attached jack-up tower crane can rise as the building rises and is suitable for high-rise buildings.

 

Tank hydraulic jacking system classified according to structural characteristics standards.

It can be divided into pitch luffing tank hydraulic jacking system and trolley luffing tank hydraulic jacking system.The tank hydraulic jacking system of the pitch luffing jib tower does not achieve luffing by lifting and lowering the boom. Its advantages are: it can give full play to the effective height of the boom, the mechanism is simple, and the disadvantage is that the minimum amplitude is limited to the maximum amplitude About 30%, it cannot be completely close to the tower body, and the load rises and falls with the boom during luffing, and the luffing with load is not allowed.

 

The trolley luffing boom tower tank hydraulic jacking system relies on the trolley installed on the horizontal boom track to achieve luffing. Its advantages are: a large luffing range, the load trolley can approach the tower body, and it can change with load. The disadvantages are that the force of the boom is complex, the structure requirements are high, and the boom and the trolley must be on the upper part of the building, and the installation height of the spire is 15-20 meters higher than the roof of the building.

 

 

The tank hydraulic jacking system is classified according to the standard of the tower structure rotation mode.

It can be divided into down-turn tank hydraulic jacking system and up-turn tank hydraulic jacking system.The tank hydraulic jacking system of the lower slewing tower crane is equipped with the slewing support and the main mechanism of the balance weight at the lower end. Its advantages are: less bending moments on the tower, low center of gravity, good stability, convenient installation and maintenance, but the disadvantages are correct The slewing bearing has high requirements and the installation height is limited.

 

The upper slewing tower tank hydraulic jacking system has the slewing support, balance weight, and main mechanisms at the upper end. Its advantage is that since the tower body does not rotate, the lower structure of the tower body can be simplified and the jacking and joints are convenient.

 

The disadvantage is that when the building exceeds the height of the tower, the rotation of the tower crane is restricted due to the influence of the balance arm. At the same time, the center of gravity is higher, the wind pressure increases, and the weight increases, which increases the total weight of the whole machine.

What is the working principle of unfixing holding-latch hydraulic jack?

Hydraulic lifting device (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

What are the characteristics of unfixing holding-latch hydraulic jack?

1.Hydraulic lifting is stable, safe and reliable. The system adopts uniform control and single or partial (several) adjustment can be realized, so the lifting process is relatively stable. Characteristics of unfixing jack determine its good self-locking performance, without tank or heavy object gliding or falling due to power outage, which ensures safe and reliable hydraulic lifting.

2.Construction quality is guaranteed. Lifting height can be precisely controlled because of adjustable function (slightly descending). Welding quality if rank is guaranteed for the reasons given above.

3. Equipment is easy for operation with good working environment and efficiency.

4. The equipment has good adaptability. This set of equipment is applicable to hydraulic lifting of large-scale storage tanks with various volumes ranging from tens of thousands of cubic meters only by regulating hydraulic hoist (unfixing jack, hoisting frame, lifting rod, etc.)

5. Hydraulic pump station can be arranged at proper position as per actual working conditions. For large scale storage tanks, hydraulic pump station can be placed inside the tank, outside the tank or space between two tanks (when one pump station controls two tanks installation) for construction control.

6. Hydraulic pump station has manual and automatic controls with apparent features as strong adaptability and good technical performance price ratio.

7.Short construction period, low cost and good economic returns. Due to high modernization of package unit and fast lifting speed, the unit has low construction cost and good economic returns. The techniques has such advantages as easier for centralized control, convenient operation, safety and reliability (no falling), precise control of weld clearance and lifting height, which guarantees project quality, saves labor and reduces cost with remarkable economical benefit.

8.Unfixing jack is widely used in project installation due to its scientific structural design. The jack is composed of upper clamp, oil cylinder, lower clamp and support. Upper and lower clamps are equipped with self locking device. Upper clamp automatically locks lifting rod when oil cylinder ascends and lower clamp automatically loosens. During stroke return, upper clamp loosens and lower clamp locks lifting rod, thus, lifting rod cannot descend and lift heavy object to designated height step by step. The heavier the object is, the tighter the locking device locks. Heavy objects will not fall even during sudden power cut or oil pipe burst. This lifting mode is proven to be safe and efficient with low cost compared with pneumatic jack, big stroke jack and high altitude stranded wire lifting. These modes are not comparable to unfixing jack in terms of safety and practicability and it is the optimal product and installation for substitution. Unfixing jack is rapidly developed and applied in inversed lifting installation of storage tanks, power plant absorption tower and stack steel lining. This jack has slight descending function, which is convenient for plate to plate butt weld. As long as chaining fixing of support and lifting point are sufficient for bearing object load, the jack can lift object to designated place safely and efficiently.
