Bucket elevator operation notes:
1. The hoist is maintained and managed by the designated personnel, and the key of the power switch box is managed by the designated personnel.
2. The hoist must have a hoist limiter and a travel limiter. The limiter should automatically stop the pulley before it is lifted 300 mm from the reel or pulley.
3. The hoist should have the maximum load mark, and the weight should not be overloaded (1T) when lifting or landing.
4. After power transmission, check the safety devices such as the hoist limiter, the travel limiter and the interlock switch. The action is sensitive and reliable, and the test is carried out.
5, before lifting, landing, ringing the alarm, before you can drive.
6, the hoist is absolutely not allowed to carry people up and down.
7. After the work is finished, the hoisting sling should be grounded, then cut off the power and close the upper and lower guardrail doors.
8. Always keep the environment around the hoist .
The daily maintenance of any machine is very important. Good maintenance can extend the life of the machine and bring higher economic benefits.
Bucket elevator maintenance:
1. The bucket elevator should drive at an empty load. Therefore, all materials in the hopper should be drained before each stop, and then parked.
2, can not be reversed, the chain can be derailed when reversed, it is very troublesome to eliminate the derailment.
3, even feeding, it is forbidden to suddenly increase the feeding amount. The feeding amount cannot exceed the conveying capacity of the hoist . Otherwise, it is easy to cause a "smuggling" accident when the material at the bottom is piled up seriously.
4. Replenish the lubricating oil in time.
5. When the chain and hopper are seriously worn or damaged, they should be replaced in time.
The operation of the bucket elevator :
Loading: In the actual process of the bucket elevator , charging is a key step. It can be said that the charging is the process of digging the material when the bucket is in the lower half of the base.
Promotion: The process in which the bucket bypasses the horizontal middle line of the bottom wheel and ends at the horizontal middle line of the head wheel, that is, the process in which the material rises vertically with the bucket is called the promotion process.
Unloading: The process of unloading the material from the discharge port when the material is removed from the upper part of the first wheel of the first wheel is called the unloading process. There are three types of unloading methods: centrifugal, gravity and confusing. Centrifugal type is used for materials with good fluidity and good scattering. Materials with more water content and poorer scattering should accept gravity discharge. Confidant discharge is better for material compliance. .
The bucket elevator is a series of hoppers that are uniformly fixed on the endless traction member, and the vertical conveying material is vertically conveyed. It is suitable for lifting and feeding of food, medicine, chemical industrial products, screws, nuts and other products. The automatic stop of the machine is controlled by the signal recognition of the packaging machine.
The bucket elevator has the advantages of large conveying capacity, high lifting height, stable and reliable operation and long service life. It can be divided into three types: ring chain, plate chain and belt.
The bucket elevator is suitable for conveying powdery, granular and small pieces of non-abrasive and low-grinding materials. The feeding of the hoist is inflow type, no need to use the bucket material, and there is little squeeze between the materials. Pressure and collision phenomena. The machine is designed to ensure that the material is less sprinkled during feeding and unloading, reducing mechanical wear. This type of hoist has less requirements on the type and characteristics of materials. It can not only improve the general powdery and small granular materials, but also improve the materials with high abrasiveness. It has good sealing performance and less environmental pollution.
The bucket elevator generally adopts inflow feeding, induction discharging, and large-capacity hopper intensive arrangement. Generally, there is no material returning and material excavation in the actual material lifting, so the invalid power is small. The advanced design principle and processing method ensure the reliability of the whole machine operation, and the trouble-free time exceeds 20,000 hours. The lifting height is high. The hoist runs smoothly, so it can reach a higher lifting height.
Manual Massage Foot Spa Massager
A manual massage Foot Spa Massager is a device designed to provide a relaxing and therapeutic foot massage. It is a manually operated handheld device, which means it does not require electricity or batteries to operate. The massager is made up of several parts, including the handle, rollers, and knobs.
