JilinProductioThe elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and enters the lower end of the hydraulic cylinder through an oil filter flameproof electromagnetic directional valve, hydraulic control one-way valve throttle valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Jilin.Small pneumatic or electric derusting, which uses the principle of friction generated by air compression or electromagnetic effects to polish and remove rust on the surface of a spiral elevator, can be used for precision instrument push rods or for enterprises that require micro operation of spiral elevators.
Before connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, first screw on the mounting bolts at any diagonal position, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked
.What types of elevators are there? There are many types of such equipment, such as fixed lifting devices and vehicular lifting devices, depending on the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
Walking: assisted self-propelled, two wheel traction, self driving, and car modification.
Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
Manual hydraulic platform classification: Manual hydraulic lifting platform vehicles can be divided into manual hydraulic handling platform vehicles, manual hydraulic stacking platform vehicles, and manual hydraulic shear type platform vehicles.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment, fixed three-dimensional parking, and other places. So what is the new price for fixed elevators?
Recommendation and consultation.The water cooling of hydraulic stations is generally tubular water cooling, and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the two types of cooling are different, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
For guideway elevators installed outdoors, they are often exposed to rain and sunlight,JilinChain guide rail lifting cargo elevator,Jilin4-ton cargo elevator, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling, and alignment, and ensure the level of the foundation and various usage requirements.
Test the goods elevator every day to see if it can operate normally.
Installation materials.The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
The main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates, connecting tubes, and connecting pieces. The materials are all selected, including the thickness of both sides of the plate, products, many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, compact structure, small impact load, stable transmission, low noise and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling, so a worm gear reducer is selected. The involute worm is used, and the material is steel. Its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear is made of polyformaldehyde. Plastic worm wheels have the advantages of good processing economy, stable transmission, vibration absorption and noise reduction, light weight, wear resistance and self reliance, making the design of the elevator more humanized.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding, the short circuit current is much larger than the normal working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Jilin.When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
The anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, we can achieve this. At the same time, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
