What Is Wet Sandblasting Technology?

 Wet blasting 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 fewer 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.

The principle of wet sandblasting

Wet sandblasting is an easy-to-automate and environmentally friendly way to circulate the grinding fluid. Check here to know wet blasting machine.

The basic principle of wet sandblasting is as follows. The grinding liquid (mixture of water and abrasive) in the grinding liquid tank is drawn to the sandblasting gun by a pump and is sprayed onto the target material by the action of compressed air in the sandblasting gun. The grinding fluid is recovered to the grinding fluid tank for recycling.

“Minimally Invasive Operation”For Laying Urban Pipe Network -- Brief Introduction of Horizontal Directional Drilling Rig

“Zipper Road”

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 causes environmental pollution, the phenomenon of digging out a part of the road is also known as the “Zipper Road”.

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 Road”.

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

Horizontal Directional Drilling Rig

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 horizontal directional drilling machine.

A 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 HDD drilling 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.

Compared with the traditional construction method, horizontal directional drilling has many advantages such as high construction efficiency, low cost, no environmental impact and so on.

Development Course of Horizontal Directional Drilling Rig

Horizontal Directional drilling 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.

THE ADVENT OF THE HDD DRILLING MACHINE

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.

THE HDD DRILLING MACHINE DEVELOP IN CHINA

China first introduced this horizontal directional drilling technology in the 1980s. With the rapid construction of crude oil pipelines and urban pipelines in recent decades, horizontal directional drilling 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.

ADVANTAGES OF HORIZONTAL DIRECTIONAL DRILLING TECHNOLOGY

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.

With the requirement of energy-saving and environmental protection getting higher and higher, horizontal directional drilling rig, a kind of trenchless pipeline laying equipment, will be used more and more widely. Check here to get HDD drilling machine price list.

Modular Pile Breaking Machine Powered By Excavator

Application

The hydraulic pile breaker is driven by hydraulic pressure and uses the power of an excavator or hydraulic station to break piles. The modular combination can efficiently break the pile heads. Hydraulic pile breaking machine cuts and removes: such as cast-in-place piles, precast piles, etc.; from the shape of the pile cutting head, it can be divided into round pile breakers and square pile machines. Pile cutters 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 cutters are suitable for pile side lengths of 300-650mm, which can meet various requirements. Requirements for large-scale foundation construction.

Development

Since the "French International Construction Machinery Exhibition" in 2012, hydraulic pile breakers have been introduced into the country to start research and development, production, and testing. The development of hydraulic pile breakers in China has not been smooth sailing. Irregular construction in China and serious pile diameter irregularities are important obstacles hindering the popularization of pile breakers. In 2014, Party A prohibited the use of breakers in the process of pile breaking. Factors such as insufficient follow-up strength of the labor force and increasing labor wages are gradually promoting the popularization of YG brand hydraulic pile-breaking machines.

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 cutting piles, mainly to destroy solid cast-in-place piles and solid precast piles. According to site requirements, the pipe piles may be destroyed.

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 pile-crushing 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.

The pile-breaking machine can use the power of the excavator to break piles. At the same time, this company also needs other excavator attachments. Such as hydraulic metal shears, vibratory rammers, rock drills, etc.

Successful! Best Diamond Wire Saw Introduction

Best diamond wire saw

If you have been looking for a diamond wire saw with fast cutting speed, long wear life, and relatively cheap price, then the information to be shared with you here will definitely shock and excite you!

I would like to introduce you to a brand new steel wire rope with "44 diamond beads per linear meter". It should be known that the ordinary wire saw can only achieve a maximum of 40 grains per line of rice, but it surpasses the tradition and achieves 44 grains! Assuming that you use 10 coils of wire rope every month, it can save your mine or stone factory more than 300,000 yuan per year and increase your total output by 25%! This is not bragging, please see my next explanation.

The formula of diamond wire saws

In the formula of diamond wire saws, there is a vital material called cobalt powder. Cobalt powder and diamond have an excellent affinity and can bond with diamonds very well. However, cobalt powder is expensive, and the price has skyrocketed in recent years, while the price of wire saws has fallen all the way. In order to survive, bad manufacturers have to reduce the content of cobalt powder in the formula and even use iron powder instead of cobalt powder. This is what we often call "iron sand rope". After a period of time, the sand iron rope will rust. Such ropes are generally incapable of cutting, slow cutting, and short-lived, which will have a serious impact on your production, and even cause huge losses such as downtime!

Industry shocking

Since cobalt powder is so expensive, can there be a relatively cheaper cobalt powder rope?

Below I will show you this rope that I especially recommend for you today. It has a low price and high quality. The cobalt powder used is imported from Italy! How does it do it?

Next, I will reveal the secrets for you, but please note that these are commercial secrets, and you must ensure that you will not use this information to do anything that violates business ethics.

What are the disadvantages of poor-quality diamond wire saws?

At present, the price of high-quality wire saws in the entire market is around 240 RMB/meter, or even higher. If you want to cut quickly and have a high output, you can't buy a rope lower than this price, because the cheap rope will have the following problems: broken rope, beading, falling off, partial wear, not sharp, not durable.

Introduction Mud Pump For Drilling Rigs

Working principle of drilling mud pump

If the entire drilling construction process is compared to human life activities, then the drilling pump, like the human heart, is the source of continuous circulation of drilling fluid from the ground to the bottom of the well, and then back to the ground from the bottom of the well. The drilling pump sucks the drilling fluid in the circulating tank, and at a pressure of 10-30 MPa and a delivery displacement of 20-60 liters per second, it passes through the ground high-pressure manifold, hose, drill pipe, and drill nozzle to the bottom of the well. , It will also form a high-pressure jet when flowing through the nozzle of the drill bit. Play the role of breaking rocks, cleaning the bottom of the well, and cooling the drill bit. When drilling with bottom hole screws or turbodrills, drilling fluid is the power source for power drilling tools. If the drilling pump fails to work normally and the drilling fluid cannot maintain circulation during the drilling process, downhole drilling engineering accidents will occur. It's as if the human heart stopped beating.

Drilling mud pump classification

A reciprocating mud pump is a kind of drilling pump commonly used in oil drilling rigs, and its function principle is exactly the same as that of general reciprocating pumps. The power end of the drilling pump is a set of crank and slider mechanisms. Because the liquid transported is mostly mud, it is also called a mud pump. There are many types of drilling pumps, which can be divided into double-cylinder pumps and triple-cylinder pumps according to the number of hydraulic cylinders of the pump. According to the number of times the piston sucks or discharges liquid once, it can be divided into single-acting pumps and double-acting pumps. At present, the most widely used oil drilling rigs at home and abroad are double-cylinder double-acting and triple-cylinder single-acting piston drilling pumps.

Work efficiency

The efficiency of drilling pumps directly affects the speed and progress of drilling. The pump valves, pistons, cylinder liners, and sealing elements of drilling pumps are the weakest part of drilling pump accessories due to the harsh working environment and conditions due to long-term working in drilling fluid containing fine sand. In recent years, with the joint efforts of scientific research and manufacturing units, my country has developed a batch of high-quality, long-life drilling pump accessories, which greatly improves the working efficiency of drilling pumps.

Mud pump development

In the 1980s, due to the rise and development of jet drilling technology, the matching and renewal speed of high-horsepower drilling pumps was greatly accelerated. In just over ten years, the mud pump has increased from 600 horsepower in the past to 800, 1000, and 1300 horsepower at present. Individual deep-well drilling teams are also equipped with 1600 horsepower drilling pumps.
