How does an orbital welding machine work?

The orbital welding machine uses the heat energy generated by the combustion of the oxygen-acetylene flame to heat the ends of the butt-welded rails to a molten state, and then applies a certain upsetting pressure to weld the rail ends. There are two existing methods: factory welding and mobile welding. Factory welding is the same as contact welding. The mobile welding method, also known as small air pressure welding, is mainly used to weld the joint joints of the long rails on the construction site. The quality of air pressure welding is also better. Aluminothermic welding. Put the prepared aluminothermic flux (made of metal aluminum, iron oxide, iron alloy and iron nail head, etc.) into a special crucible, ignite the flux with a high-temperature match, and produce a strong chemical reduction reaction to obtain high-temperature molten steel and molten steel. Slag, after the reaction is calm, inject it into the preheated sand mold tightly fastened to the ends of the two rails, melt both ends of the butt joints, remove the sand mold after cooling, and reshape the welded joint in time. Welded into one. The quality of aluminothermic welding is poor, and the fatigue strength is even worse, only reaching 45% to 70% of the base metal.

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?

What are the precautions for the use of hydraulic storage tank lifting equipment?

1. Hydraulic jacks cannot be used as permanent support equipment. For long-term support, the support part should be added under the heavy object to ensure that the hydraulic jack is not damaged.

2. If only one hydraulic storage tank lifting equipment is used to lift one end of the heavy object, the hydraulic storage tank lifting equipment should be placed on the symmetrical axis of the heavy object, and the long direction of the hydraulic jack base and the easy toppling of the heavy object should be made. the same direction. If two hydraulic jacks are used at one end of the heavy object, the direction of the base should be slightly symmetrical and placed on both sides of the symmetrical axis of the heavy object.

3. When two or more hydraulic storage tank lifting equipment are used to lift at the same time, they must be commanded, coordinated, and lifted at the same time.

4. Hydraulic storage tank lifting equipment should be stored in a dry and dust-free place. It is not suitable for use in workplaces with acid, alkali and corrosive gases, and it should not be placed outdoors in the sun and rain!

What are the structural parts of hydraulic storage tank lifting equipment?

The hydraulic storage tank lifting equipment is a piston type lifting equipment, consisting of a hydraulic control cabinet (pumping station), the main bearing of the high-pressure oil pipe, the accessories of the hydraulic pump system, the oil control valve, the piston jack, the ring wire rope hanger, and the pumping station by two independent Composed of a hydraulic lifting unit and a centralized electrical control cabinet, it can serve the lifting of two 10000m³ tanks at the same time. Each 10000m³ tank is equipped with 20 jacks. The total composition of the hydraulic oil pipe is distributed in two stages, and then the hydraulic oil is sent to the hydraulic jack. Short construction period, low cost and good economic benefits are its significant advantages.

What should be paid attention to before using hydraulic storage tank lifting equipment?

1. Before lifting, put the slotted end of the handle into the oil return valve stem, and tighten the oil return valve stem clockwise.

2. The handle of hydraulic storage tank lifting equipment is inserted into the handle hole and pressed up and down, and the piston rod will rise steadily to lift the heavy object. Due to the limiting device in the jack, it will not rise when it reaches a certain height.

3. To lower the piston of hydraulic storage tank lifting equipment, just use the slotted end of the handle to slightly loosen the oil return valve rod counterclockwise (no more than 2 turns), and the piston rod will gradually descend. If there is a load, the oil return valve stem should not rotate too fast, otherwise it will be dangerous if the descending speed is too large.

What is the working principle of hydraulic jacking system?

Hydraulic jacking system (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 jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, 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.
