1. Strength of sandblasting equipment

The main process parameters that affect the intensity of blasting are: blasting diameter, blasting speed, blasting flow, and blasting time. The larger the diameter of the sand blast, the faster the speed, the greater the intensity of sandblasting, the stronger the collision of the workpiece, and the greater the intensity of sandblasting. Sandblasting strength requires a certain amount of sandblasting time for the sandblasting machine to ensure that the sandblasting intensity reaches saturation within a certain period of time, and the sandblasting time is prolonged and the intensity no longer increases significantly. In the sandblasting strength test, the characteristics of the sandblasting strength are improved through the deformation of the test piece. Now contact us to get a cheap sand blaster machine factory price.

• 

• 

2. Sandblasting coverage

Factors affecting coverage include material hardness, blasting diameter, injection angle and distance, and blasting time. Under the specified sandblasting intensity, when the hardness of the workpiece is lower than or equal to the hardness of the standard test board, the coverage can reach 100%. Conversely, the search speed will decrease. Under the same blasting flow, the longer the distance between the nozzle and the workpiece, the smaller the jet angle, the smaller the blasting diameter, and the shorter the coverage required time. When the blasting strength is increased, the blasting, injection angle and distance of the appropriate size should be selected to achieve the required value. Click here you can check our sandblasters for sale.

3. Surface roughness of work piece

The factors that affect the surface roughness are the strength and hardness of the material, the diameter of sandblasting, the angle and speed of sandblasting, and the surface roughness of parts.

Under other conditions, the strength and surface hardness of some materials are higher, the plastic deformation is more difficult, the shallow hole is shallow, the surface roughness value is small, the diameter of the sandblasting is smaller, the speed is slower, and the lighter crater , The surface roughness is small. The larger the jet angle, the smaller the blasting speed, the smaller the impact pit, and the shallower the tangential velocity. The greater the tangential velocity, the greater the impact of sandblasting surface grinding and the smaller the surface roughness. The surface roughness of parts is also one of the influencing factors. If you are looking for portable shotblasting machine for sale, please leave your message.

The mini roller compactor has the advantages of convenient operation, small size, light weight, suitable for compaction operations in narrow areas and places where large road rollers cannot be driven. It has been widely used, but due to factors such as large engineering workload and long working hours, When mini road roller is performing compaction work, it is inevitable that there will be some failures. If it is not solved in time, it will not only affect the work efficiency but also delay the construction period.

• 

• 

Engine won’t start

Causes of failure: fuel exhaustion; fuel filter blockage; fuel pipe leakage; battery leakage or poor connection.

Solution: Fill the fuel tank with fuel; replace the filter; check whether the battery is deficient, charge it in time if it is deficient, replace the battery with a new one, and check the circuit.

Brake failure

The cause of the failure: there is dust and dirt on the friction plate, or it is damaged; there is a problem with the brake connection.

Solution: Remove the dust and dirt on the friction plate, and replace it with a new one if it is damaged; check the connector line failure and repair it.

• 

• 

Under pressure

The cause of the failure: It may be due to the blockage of the pilot relief valve of the small roller compactor that the control oil has no pressure or the hydraulic pump has no pressure; the amount of fuel is insufficient; the relevant parts are worn out and the coordination fails.

Solution: Check whether the overflow valve is blocked, and deal with it in time; replace the fuel with good quality; check the wear of related parts and repair it in time.

The road roller machine cannot change speed when walking

The cause of the failure: The variable motor mechanism cannot change speed because the displacement control mechanism of the variable motor cannot be opened normally or has a malfunction.

Solution: Check whether the walking speed control switch is in good condition, whether the variable speed solenoid valve is normal, and whether the circuit is unobstructed at the solenoid valve part to ensure that the solenoid valve can be opened smoothly and connected to the variable speed control oil circuit to ensure that its pressure is normal (the pressure is complementary Oil pressure).

When troubleshooting the road roller machine, be sure to perform a good maintenance for every failure so that the machine can take advantage of its performance. When mini road compactor is in operation, it is necessary to take a proper rest and allow it to be adjusted well, so as not to cause greater wear and tear of the road roller due to long-term operation, thereby reducing its life. If you have any other questions about mini road roller, you can call us and we will do our best to serve you.

Road rollers, also called road compactors, are a kind of road construction machinery that can often be seen. Its working principle is mainly to use its own gravity to plastically strengthen the compaction of those sandy, semi-clay soil or asphalt concrete pavements.

• 

• 

Principles of roller rollers:

1. The compaction of the pavement should start from the edges on both sides of the road and gradually move to the center of the road. The rolling belt during the two rolling before and after rolling should have a fixed overlap width. The overlap width of the tandem roller and the single-wheel vibratory roller is 250-300mm, and the overlap width of the static three-wheel roller can be half of the main road roller.

2. The roller should be rolled as close as possible to the paver, and the method of applying light first and then heavy should be adopted to ensure that the compactness requirement is reached before the mixture is cooled to below the required low temperature.

3. Pay attention to the temperature when rolling. Petroleum asphalt is between 80～150℃ (residual asphalt is 90～110℃, if the rolling temperature is too high, the material will be squeezed in front of the roller, and it will expand along the edge of the roller to produce transverse cracks and adhere to the roller. When the rolling temperature is too low, the viscosity of the asphalt becomes high and it is difficult to compact, and cracks will appear on the rolled road.

4. When rolling the new asphalt mixture, the operator should first drive the driving wheel into the fresh mixture yard to reduce ripples and breakage. Keep the rolling speed constant, do not stop arbitrarily on the hot material surface; turn or start slowly, so as to minimize the indentation.

• 

• 

Problems that need to be paid attention to when the road roller machine is rolling

1. When compacting loose materials, you should go through 1 to 2 times of static pressure before vibrating rolling.

2. When working on a ramp, the speed should be as low as possible, and driving on a cross slope greater than 20% is prohibited.

3. Use a low speed when working on the road roller. When working, pay attention to whether there are people or obstacles on the front, back, left, or right.

4. Pay attention to the formation and separation distance (3-5 meters front and rear, 0.5-1 meters left and right) when multiple rollers work together, and low speed (0-7km/h) when driving on slopes to prevent inertial landslides and crushing. Rolling must be carried out in accordance with the rolling process specified by the construction personnel during the rolling. No leakage during rolling, no change of the rolling speed, and no stopping at will.

In recent years, a sharp weapon similar to blood drops is dedicated to removing pile heads and repairing pile foundations. To get rid of the redundant parts of solid concrete cast-in-place piles and precast piles, this kind of weapon is the concrete breaker machine, Pile Breaker, and Pile Cutter. Don’t look at the appearance like a fancy round hanger; it is very powerful.

• 

• 

The pile breaking machine can provide pressure to multiple cylinders at the same time. The cylinders drive drill rods distributed in different radial directions and simultaneously squeeze the pile body. It is like a concrete solid column with a diameter of one or two meters at the same time. Like a bean sprout, it was cut off instantly, leaving only steel bars.

The pile breaker can be connected to a variety of construction machinery, hung on excavators, cranes, telescopic booms and other construction machinery, simple operation, low noise, low cost, work efficiency is dozens of times that of manual pneumatic picks, two operations 80 piles can be destroyed in one day, which is especially suitable for pile group construction projects.

Working principle of hydraulic pile breaker:

A concrete breaker machine is a new type of pile-breaking operation equipment, which uses hydraulic principles to controllably split objects. Especially in places where there are strict restrictions on dust, flying debris, vibration, noise, and exhaust emissions, the piling cutter has special advantages that it cannot replace. This machine is suitable for cutting round and square pile heads in pile foundation projects such as high-speed railway bridges, industrial and agricultural buildings. Through the remote control of construction machinery, the pile head can be cut safely and efficiently. It can avoid personal injury caused by manual construction, and the efficiency is dozens of times that of manual construction.

thermoplastic road marking machine

A thermoplastic road marking machine is a kind of equipment for pavement construction. It is widely used in parking lot marking construction and road traffic marking construction. Although there are many line marking machines on the market, the quality of marking is closely related to many factors, such as Pavement environment, marking paint quality, road quality, air humidity and temperature during construction, etc. If there is not much work required for hot melt marking in road traffic, for example, some road sections need to be re-marked, you can use an ordinary hand-push thermoplastic road marking machine, because of its small size, flexible construction, and convenient transportation. The team can quickly take it to the construction site for construction. During marking construction, heat and stir the powder coating with a hot melt kettle until it melts into a liquid state. Be careful not to overheat or low the temperature. Then put the paint into the marking machine for marking construction. Since the melting temperature of the coating is directly related to the quality of the marking, the hot melt kettle is a key component of the thermoplastic road marking equipment and an important part of the coating melting. The line drawn by the hot melt kettle is pressure-resistant and wear-resistant, and the color is durable and clear. Easy to identify.
