What are the lubrication methods of vibrating screen?

In the mine production site, vibrating screen is a common equipment, which needs to screen and dehydrate materials. Since it is a large-scale equipment and the workload of the equipment is large, the maintenance work of the vibrating screen should be done well at ordinary times, and the lubrication and maintenance can ensure the normal production and operation of the vibrating screen. So what kind of lubrication is used for the vibrating screen? Generally, there are two types of lubrication, oil lubrication and grease lubrication. The following editors from Hiside will give you a detailed introduction.

1. Lubrication method of vibrating screen

Oil lubrication of vibrating screen

Lubricating oil has strong fluidity and dispersibility, so the oil-lubricated seal needs to be safe and reliable. The sealing device is more complicated than grease lubrication, and it is more difficult to disassemble and maintain. Oil lubrication is generally suitable for bearings operating at high speeds or in environments with high bearing temperatures. Commonly used oil lubrication methods include oil bath lubrication, circulating oil lubrication, drip oil lubrication, oil injection lubrication, and oil and gas lubrication.

Grease lubrication of vibrating screen

Grease has the characteristics of strong adhesion, not easy to run off, and good pressure resistance. Due to the weak fluidity of the grease, the grease lubricated sealing device is relatively simple, the disassembly and maintenance are more convenient, and a special oil supply system is not required. Grease lubrication is generally suitable for work in low and medium speed and moderate temperature environments. Commonly used greases are calcium-based grease, sodium-based grease, aluminum-based grease, general-purpose lithium-based grease, extreme-pressure lithium-based grease and molybdenum disulfide extreme-pressure lithium-based grease.

How to maintain the roller skin of the briquetting machine?

In modern industrial production, in order to save raw materials, various equipment in various industries emerge in an endless stream. As an important equipment for processing and reusing residual materials, briquetting machine will inevitably experience various wear and aging during use. Important working components in the briquetting machine Roller skins are often worn out and replaced.

The roller skin is a cylindrical component with ball sockets dug on the surface of the roller core of the ball press. Usually, the material is pressed by hydraulic drive rollers, which are formed by the ball sockets of the roller skin. As a very easy to wear ball press component, Frequent replacement is unacceptable for the operator, but the worn roller skin of the ball press cannot meet the production demand, and it is not enough if it is not replaced, so it is very important to maintain the roller skin during use. What is the maintenance method of the roller skin?

1. The installation of the roller skin of the briquetting machine should be correct

There are four installation methods for the roller skin of the ball press. Different ball presses use different methods, but the installation standards are the same. First of all, the installation of the roller skin cannot be dislocated. If the roller skin is already dislocated during installation, then Not to mention production, the shape of the ball socket on the roller skin must be aligned, otherwise the ball press will not produce balls, loose balls, and the spherical shape is not true. The edges of the nests wear each other, and the roller skins need to be replaced after a long time, which is not worth the loss.

briquetting machine

2. Do a good job of protection before the briquetting machine works

The common steel for the roll skin of the casting ball press is 65 manganese alloy, and the common steel for the roll skin of the forging ball press is 92 chromium molybdenum. Our company uses a higher-level forging – bearing steel. Casting roller skins are relatively not wear-resistant, but the advantage is low cost. Some operators are not bad at money, and it is not a big deal to replace the roller skins frequently. However, for operators who use forged roller skins, the more durable the roller skins, the better. It is better not to replace it, but it is not necessary to maintain the roller skin of the ball press.

How to Extend Tractor Clutch Life

The tractor clutch is through the operating mechanism, relying on the friction between the main and driven components, to temporarily separate or gradually connect the engine and the transmission to transmit power, facilitate shifting, ensure a smooth start of the tractor, and prevent damage to parts caused by overloading. During the use of the tractor, many drivers cannot use and maintain the clutch properly, and do not realize the importance of correct adjustment of the clutch. Often due to improper adjustment of the use and operation, the early wear of the clutch and the damage of the transmission parts are caused, which reduces the service life. In order to reduce the failure of the clutch and prolong its service life, it must be used and adjusted correctly.

Correct use and maintenance

(1) When using the clutch, do it quickly and completely when disengaging, and slowly release the pedal when engaging. When the tractor starts, release the pedals quickly. Obstacles and rough terrain cannot be overcome by slamming the clutch pedal.

(2) The time for stepping on the clutch pedal to separate should not be too long, generally not more than 15 to 20 s. If you need to stop for a long time, the gear lever should be in the neutral position and the pedal should be released.

(3) Do not habitually press your feet on the pedals. When driving, do not step on the clutch pedal at all times except for starting, shifting and braking at low speeds. Otherwise, the clutch is often engaged, disengaged or semi-slipped, which will accelerate the wear of the clutch friction plate and pressure plate.

(4) Try to avoid starting with a heavy load. When the tractor starts with a heavy load, the clutch is prone to serious slippage, which generates frictional heat and burns, cracks, warps and deforms the pressure plate and driven plate of the clutch, and the compression spring is annealed. The asbestos friction plate is generally within the working temperature of 400 ℃, and the friction coefficient above this temperature decreases with the increase of temperature. Therefore, during heavy-load operations, if the ploughed land encounters local resistance changes, it is necessary to shift gears in time, and the plow should be slightly lifted before starting to reduce the starting resistance.

(5) When stopping normally, the accelerator should be closed first, then the clutch should be disengaged, and the brake should be properly used to make the locomotive stop smoothly; when stopping in an emergency, the accelerator should be quickly closed, and the brake pedal should be quickly pressed, and then the clutch should be disengaged. The double-acting clutch can operate the PTO handle only after the second-stage friction plate is disengaged.

(6) In use, the friction plate adheres to oil, which will cause the clutch to slip; the clutch will be immersed in muddy water, which will cause the parts to rust. At this time, the clutch must be disassembled, the muddy water should be wiped off with cotton yarn, the oil stains and rust spots should be cleaned with gasoline, and the friction plates should be reassembled after drying in the shade or drying (no drying is allowed). When the clutch assembly is installed on the flywheel of the engine, it is best to use a mandrel for positioning, which can ensure the concentricity of the center of the clutch friction plate and the first shaft, and make the gearbox and the engine assemble smoothly.
