What is wet sandblasting?

Wet blasting machine is a technique for surface preparation using water, abrasives and compressed air.

"Wet blasting" refers to a technology that uses the power of compressed air to spray a mixture of water and abrasives at high speed to achieve surface cleaning, processing and modification of metals, plastics, ceramics and other materials. Since it is wet processing, it is also suitable for fine processing using abrasives as small as several microns.

Advantages of wet blasting

Wide selection of abrasive grain sizes, shapes and materials

Because the abrasive particles are carried by water to the target, finer particles can be used compared to dry blasting.

High fluid control and controllability

The grinding fluid mixed with water and abrasive grains can realize fluid control, so the processing precision is higher.

Less abrasive residue

After machining, the abrasive particles are washed away by water, so less particles remain on the machined surface.

Capable of handling ultra-thin targets

The processing pressure is small, and the ultra-thin target will not be damaged during processing.

Adding chemicals can get the effect of secondary treatment

Chemicals can be dissolved in water, and chemical treatment can be performed at the same time as sandblasting. Click here to know more automatic sandblasting machine for sale.

The principle of wet sandblasting

Wet sandblasting is an easy-to-automate and environmentally friendly way to circulate the grinding fluid.

We often find that in the city where we live, roads are often dug up. Whether newly built or used for a period of time, we always feel that the roads around our residence have never been intact. We dig and repair them every day, it is not convenient to travel, but also cause environmental pollution, the phenomenon of digging out a part of the road is also known as the “Zipper link.”.

The main reason for this type of Zipper is not only that the road is damaged, but also that the road was not well planned when it was built, and with the rapid development of the city, the existing underground pipelines can not keep up with the demand of the city, in addition, some new pipelines also need to cross the road.

A few days ago, I saw a news report that a certain place has stipulated that the newly-built urban roads should not be dug up for 5 years after they are delivered for use. This will effectively put an end to the phenomenon that urban roads are often dug up. It will also avoid the economic losses caused by the repeated occurrence of “Zipper links”.

But at the same time, it puts forward higher request to the construction of the underground pipe network of the city road.

Do you often see a machine at work in the city’s green belt, or on the sidewalk, inserting a rotating iron pipe into the ground to make a hole, and not far away inserting cables and pipes into the hole made by the machine, this machine is the HDD drilling machine.

Horizontal Directional Drilling Machine is the mechanical equipment for laying underground pipelines without the need to excavate the ground. It can avoid obstacles successfully within a certain radius of the ground. It can be operated in underground strata such as clay, sand and so on. It is widely used in electric power, flexible pipeline laying in the fields of communications, oil and natural gas.

Unlike road closures and major road repairs, horizontal directional drilling rigs can be built on the side of the road without affecting traffic or people’s normal travel, as we often see.

Through the advanced equipment calculation and positioning, can let the whole drill through the process of bypassing obstacles to reach the intended location, to ensure the construction accuracy.

HDD drilling machine is a new construction method that combines the common pipeline laying technology with the drilling technology used in oil exploitation.

When the horizontal directional drilling machine was not invented, it was not only inefficient but also costly to dig holes and sink pipes when laying pipelines to cross rivers or obstacles.

Horizontal Directional drilling first appeared in the United States, in the 1960s, an American engineer used oil field directional drilling technology in the pipeline.

Later, reaming technology was invented, which also made it possible to lay large diameter pipes, and a new horizontal directional drilling technology was formed.

China first introduced this HDD drilling technology in the 1980s. With the rapid construction of crude oil pipelines and urban pipelines in recent decades, horizontal directional drilling machine has developed rapidly in China, both the length of the crossing and the diameter of the pipeline have set many records.

We all know that it takes a lot of skill to extract oil, and that’s because it’s buried in the ground where you can’t see it, and it takes a lot of hard work to extract it.

In the exploitation of the first need to carry out very important drilling work, but also according to different geological and use different methods to drill wells, so as to obtain oil resources.

The traditional method of drilling wells is usually vertical drilling, but in many cases, horizontal drilling in the ground is used to find oil. This technique uses advanced acoustic and Gamma-Ray functions on the drill bit when drilling, the data in the formation is collected by the bit and transmitted to the ground operator, so that a more ideal drilling plan can be adopted in real-time, and the bit can be controlled to bend forward in the ground at will, that would be like installing a clairvoyant on an underground drill that would eventually find oil.

Since the appearance of the horizontal directional drilling technology, the human drilling technology has improved a step, improved the production efficiency, and reduced the engineering risk.

The structure of the concrete gunite machine is simple and reasonable and easy to operate. Humanized design and reliable performance.

Application

The hydraulic pile breaker is driven by hydraulic pressure and uses the power of an excavator or hydraulic station to break piles. Modular combination can effectively break the pile head. Hydraulic pile breaker cutting and dismantling: such as cast-in-place piles, precast piles, etc.; from the shape of the pile driver, it can be divided into circular pile drivers and square pile drivers. Pile drivers are widely used in high-speed railway bridges, industrial and civil construction pile foundation projects. Generally circular pile cutters are suitable for pile diameters of 150mm-2500mm; square pile shears are suitable for pile side lengths of 300-650mm, which can meet various large-scale foundation construction requirements.

Developing

Since the "France International Construction Machinery Exhibition" in 2012, hydraulic pile breakers have been introduced into the country, and research and development, production and testing have begun. The development of hydraulic pile breakers in China has not been smooth sailing. Irregular construction and serious irregular pile diameters in our country are important obstacles hindering the popularization of pile breaking machines. In 2014, Party A prohibited the use of breakers in the piling process. Factors such as insufficient labor force follow-up and rising labor wages are gradually promoting the popularization of hydraulic pile breakers.

Structure

The hydraulic pile breaker is composed of modules, which can be installed and disassembled by itself according to the diameter of the broken pile head. It is installed at the front end of an excavator or crane, and uses the power of an excavator or hydraulic station to break piles, mainly to destroy solid cast-in-place piles and solid precast piles. According to site requirements, the pipe piles may be destroyed. Click here to knoe more details.

Working Principle

The pile breaker provides pressure to multiple cylinders of the pile cutter through a power source, and the cylinders directly drive the drill rods while squeezing the pile body to cut off the pile head. During the construction process of the YG engineering pile cutting machine, the operation is simple, high efficiency, low noise, low cost, and it is suitable for pile group construction projects. The pile breaker adopts a highly modular combination, and the modules are connected through a pin shaft, and the pile heads within a certain range of diameter can be cut through the combination of different module numbers.
