Below is the right.ElevatorDefect Analysis of Gas Shielded Welding

　　ElevatorIt is a kind of equipment used for high-rise cargo handling. Its gas shielded welding refers to the method of welding with flux-cored wire under gas protection. Flux-cored wire is a kind of welding wire made by rolling thin steel plate into round steel pipe or special-shaped steel pipe, filling a certain amount of powder in the pipe and drawing. In the process of lifting equipment, the function of powder is the same as that of welding rod flux skin, the welding process of flux-cored wire gas shielded welding is actually a process of gas-slag joint protection. This method has advantages, but it also has some shortcomings. Let's share the shortcomings of gas shielded welding.

1. The wind resistance is weak. When CO2 gas shielded welding is carried out on the outdoor elevator, corresponding wind-proof measures must be taken to prevent potential safety hazards.

2. The splash is very large, and the spatter cleaning after gas shielded arc welding is more troublesome, but under normal conditions, the spatter generated is much less than that of alkaline electrode arc welding, so this is not a big disadvantage.

3. The operation is not flexible enough within a certain range. The welding torch and wire feeding hose of CO2 gas shielded welding are relatively heavy, so it is not flexible enough to operate in a small range.

4. Strong arc, the arc of CO2 gas shielded welding is very strong, and the protection should be strengthened during welding to avoid affecting the staff.

What issues need to be considered when choosing a fuel tank for a lift?

　　ElevatorIt is a kind of equipment with very simple structure and convenient maintenance. As a multifunctional lifting and handling equipment, its lifting system is mainly driven by hydraulic pressure, so it is also called hydraulically driven lifting equipment. The hydraulic oil tank of the equipment is mainly used for oil storage and heat dissipation., Separate the air in the oil and clean up the foam. Of course, the prerequisite for realizing these functions is to ensure the quality of the oil tank. Here I share some issues that need to consider when choosing the oil tank.

1. Oil tank structure. The partition plate in the traditional oil tank cannot play the role of precipitating dirt. A vertical partition plate needs to be installed along the longitudinal axis of the oil tank. There is a space between one end of the partition plate and the end plate of the oil tank to connect the space between the two sides of the partition plate. The oil inlet and the oil outlet of the elevator hydraulic pump are arranged on both sides of the partition plate at the unconnected end.

2. Considering the oil level of the oil tank, when all the hydraulic cylinders of the system are extended, the oil level of the oil tank cannot be lower than the low level of the oil level. After the oil cylinder is retracted, the oil level cannot be higher than the high level.

Taking into account the capacity, pumping to large flow tank capacity is generally 2 to 3 times the mobile equipment, pumping to large flow is 3 to 4 times the fixed equipment.

Well, let's talk about it today. Thank you for watching.
