In China, automatic mortar jetting machines are widely used in diversion tunnels, highways, tunnels, and various underground constructions. Automatic mortar jetting machines have their own walking ability and can walk flexibly on slopes less than or equal to 12 degrees. Automatic mortar jetting machines can According to engineering requirements, one to three shotcrete machines are equipped to solve the shortcomings of traditional manual feeding. Its appearance is the improvement of the spanning of tunnel shotcrete construction. So how should the shotcrete truck be maintained during use?
Automatic mortar jetting machines is an important pipeline for conveying slurry. Its quality will reduce the loss of slurry, and it is also an important accessory to improve work efficiency. When choosing, you should ask whether the manufacturer is made of highly wear-resistant synthetic rubber and nanomaterials, and observe the cut surface of the shotcrete pipe to observe the inner and outer layers to see if the steel wire reinforcement layer and the corrosion-resistant outer rubber layer are used. If they are all in line, you can buy with confidence. If you buy the product online, you can consult the relevant manufacturers and check the related issues after the goods are delivered. If they are not in line, they can be returned to avoid being unable to return due to use. The tapered casing is generally made of polyurethane material, which has the characteristics of wear resistance, pressure resistance, and not easy to break. When purchasing the tapered casing, gently fold it by hand to see if there are small cracks at the crease. It indicates that the quality of the product is not good enough, and the wear resistance is not good. It is recommended not to buy this type of product. High-quality tapered sleeves will not appear small cracks in the creases when they are lightly folded by hand, and the creases will gradually disappear after recovery and will not be deformed.
Instructions for quick use of automatic mortar jetting machine
The first step: Connect the power supply, start the main motor by jog to test the forward and reverse rotation, and turn in the direction of the arrow. Pay attention to jog start, that is, turn off as soon as it is turned on. The machine is strictly prohibited from reverse rotation and idling for a long time.
The two step: Install the shotcrete pipe, add water to the hopper, and start the machine to lubricate the pipe with water.
The third step: add material to the hopper, pull the other end of the sandblasting tube into the hopper, let the machine circulate and discharge the material for a few minutes, then install the spray gun, connect the air pipe to spray, and stop the machine for more than 20 minutes in the middle to let the machine circulate out Feed it to prevent sand precipitation from causing pipe blockage.
The fourth step: cleaning after use, directly add water to the machine hopper, start to fetch water until clear water comes out, cleaning is completed, it is best to make pure cement slurry for the first use every day to prevent the remaining sand in the pipeline from blocking the pipe.
The new generation of automatic mortar spraying machine fundamentally solves the shortcomings of "low efficiency, high energy consumption, high resilience, and high pollution". Not only that, the automation system is more convenient to operate, and it can move forward and backward freely in engineering operations, thus avoiding the use of loaders. The trouble of hanging and the length of time.
