In the mining sand and gravel industry, vibrating screens are often used to screen materials. Generally, the production in this industry is in an open-air environment, so sometimes bad weather is encountered. The main screening object in the vibrating screen, the screen, is sometimes inevitably affected by rain, etc., which will cause the screen to rust. However, the rust of the vibrating screen will not only affect the production efficiency of the vibrating screen, but also It affects the production efficiency of the entire machine-made sand production line, so when rust occurs, it must be dealt with in time.

How to prevent the vibrating screen from rusting

1. Select high-quality equipment

Choose a vibrating screen equipment with good material quality, and the quality of its accessories is also good, and it is not easy to rust. Therefore, high-quality screen material can largely avoid the occurrence of rust.

2. Cover the protective layer

Set a protective layer on the screen of the vibrating screen, for example, apply vaseline, oil, paint, etc. on the screen, or use hot-dip, electroplating, sputtering and other methods to coat the screen with corrosion-resistant metal, usually forming an oxide film, isolating The air will corrode the screen, and then do a good job of rust prevention and reduce the rust of the screen. Because the rust of the screen is mainly due to the chemical reaction between its surface and the moisture in the air, so in order to do a good job in the anti-rust work of the screen, the screen of the vibrating screen must be isolated from the air.

Valve bags are now widely used in our lives, and they are used in different industries. The characteristics of valve pockets are convenient transportation of goods, strong firmness, improved packaging efficiency, low damage rate, and there are many types of valve pockets. The machine manufacturer will now explain to you what are the classifications of valve pockets? Let’s keep reading.

Classification of valve bags

1. Multi-layer kraft paper bag: use two or more layers of kraft paper for further processing on the machine, make it into a bag shape, use polyester thread to reinforce and sew the bottom, and then use heat-sealing paper for heat-sealing treatment .

2. Paper-plastic composite bag: It is also a three-in-one kraft paper bag. The outer layer of the paper bag is kraft paper, and the inner layer of the paper bag is a plastic PP woven bag. EVA, PP, PE and other raw materials are used for high-temperature composite treatment. After completion, according to different Kind of material for one-step bottom treatment.

3. Square bottom open bag: It is basically the same as the multi-layer kraft paper bag. After the semi-finished product is made on the machine, the bottom is manually folded to make a square bottom. The bottom is glued with glue, and then dried by heat sealing or drying. Type processing, complete the production of open bags.

4. Square bottom valve bag: The basic production process is the same as that of the square bottom open bag. The square bottom valve bag is made by a square bottom machine. The valve bag has the same treatment on the mouth and bottom, and at the same time adds a kind of horn to the mouth. mouth, convenient for filling materials.

In this era of intelligence, the intelligent compact shelf is a very popular one, and it stands out among many products with its unique intelligent system. No matter how good things are, there will be some problems or damages when they are used. Let’s introduce the common faults and solutions of smart compact shelves in detail. Let’s find out together!

Common Faults of Smart Shelves

1. When operating the control panel of the intelligent compact shelf, the shelf can not work according to our instructions, but the indicator light on one side of the shelf can light up normally. In this case, the system circuit will fail due to long-term non-use, mainly because the fuse on the control circuit board is blown, resulting in disconnection. The user should check whether the fuse in the distribution box is normal in time and replace it in time to ensure its normal operation.

2. The intelligent compact rack cannot be used, the control screen does not appear, and the indicator light does not light up

Not available. We must first check whether the power supply is normal. It may be that the power supply is not turned on, or it may be that the intelligent intensive cabinet is overloaded due to operational errors, resulting in direct damage to the system. If this is the case, you need to reinstall the smart shelf, please contact the manufacturer, and it will not be able to be installed without a person.

3. The computer announces the command, but the product does not respond

Reason: The power supply of the fixed column panel is bad or the computer port is not set correctly. Solution: Press the power switch on the fixed column button to reset the ports on the computer.

4. When the computer is running, the screen state is disordered

Reason: signal scramble or virus intrusion, the plug of the signal cable is loose. Treatment: Turn off the power and restart, check whether the connector can still be used, and start the self-check function of the file storage rack system to automatically repair; if there is still a problem, please contact the manufacturer to send a technician.

The tractor clutch is installed after the engine and before the transmission. Its basic function is to transmit and cut off the power. The main function is to transmit the power from the engine to the transmission; the second is to ensure that the engine starts and the tractor starts smoothly; Temporary parking; fourth, to prevent overloading of the transmission system; fifth, the double-acting clutch also plays the role of transmitting or cutting off the power output.

However, tractor clutches often fail frequently during use. In fact, among the clutch failures, in addition to the quality problems and design problems of the clutch itself, a large part of the failures are related to improper use and operation. The following tractor clutch manufacturers will give you the details. Introduce the correct operation and use of the tractor clutch.

Do not step on the clutch, do not step on the clutch halfway.

Some tractor operators habitually put their feet on the clutch pedal when working. This habit is not good, and it is easy to damage the clutch. When the clutch of the tractor is working normally, the disc spring tightly presses the friction plate on the flywheel of the engine, and the clutch is in the state of pressing and engaging, and the friction plate does not slip.

When the clutch needs to be disengaged, it is realized by stepping on the clutch pedal. If the tractor is always half-stepped on the clutch, and the foot is placed on the clutch pedal for a long time, the clutch will often be in a semi-engaged and disengaged state, making the clutch It is in a semi-slip state during operation, which accelerates the wear of the clutch friction plate and pressure plate, and reduces the ability of the clutch to transmit torque. It is easy to cause the clutch to slip and burn the friction plate. The end face of the flywheel is ablated and pulled, and the clutch disc spring is annealed. When driving a tractor, you generally do not need to step on the clutch except for starting, shifting and braking at low speed, and you generally do not need to step on the clutch at other times. At this time, do not always step on the clutch pedal.

Correct operation of the tractor when starting.

When the tractor starts, it is necessary to depress the clutch to engage the gear. When depressing the clutch, depress the clutch pedal quickly, and go all the way to the end, so that the clutch can be completely separated, then engage the gear, and then release the clutch pedal; when releasing the clutch pedal, Operate according to the principle of “fast first, then slow”, that is, the free stroke before the clutch is not engaged can be lifted slightly faster, when the clutch starts to engage and appears semi-linked (the engine sound changes at this time), it should stop for a while, and then Slowly lift the clutch pedal (at the same time gradually add the throttle), that is to say, in the process from semi-linked to fully combined, the pedal should be lifted slowly to make the clutch engagement smooth, and while the clutch pedal is slowly lifted, according to the size of the engine resistance Gradually step on the accelerator pedal, the operation of the accelerator should be smooth and appropriate, so that the tractor starts smoothly. After the clutch is fully engaged and the tractor starts smoothly, you should quickly remove your foot from the pedal and place it under the pedal. When the tractor is not using the clutch, it is strictly forbidden to put your foot on the clutch pedal.

When it comes to calcium hydroxide, many people may not know what it is. It should be more familiar with slaked lime and slaked lime, especially in chemical experiments and physical experiments. So, in addition to being able to do experiments, do you know any other uses for this calcium hydroxide?

WHAT IS CALCIUM HYDROXIDE

Calcium hydroxide is a fine white powder produced by a professional calcium hydroxide production line, which is odorless and slightly bitter in taste. It is easy to absorb carbon dioxide and become calcium carbonate when placed in the air. It is made of calcium oxide, that is, quicklime, digested with water, dried, sieved, and air-selected (or crushed by an extension machine).

The chemical formula Ca(OH)2, commonly known as slaked lime and slaked lime, is formed into two layers after adding water. The upper aqueous solution is called clarified lime water, and the lower suspension is called lime milk or lime slurry.

The supernatant clear lime water can test carbon dioxide, and the lower turbid liquid lime milk is a building material. Calcium hydroxide is a binary medium and strong base (calcium hydroxide is considered to be a strong base in the middle school stage, but in fact it cannot be completely ionized in water. It has the property of alkali and has a corrosive effect on skin and fabrics. It has a wide range of applications in industry. It is a commonly used building material, and is also used as a fungicide and chemical raw materials.

Calcium hydroxide is a strong alkaline substance with irritating and corrosive effects. Inhalation of dust is highly irritating to the respiratory tract and may also cause pneumonia. Eye contact is also strongly irritating and can cause burns.

USES OF CALCIUM HYDROXIDE

With the development of modern industry, lime has opened up a variety of uses in many emerging industrial sectors besides the main material of civil engineering. Such as metallurgy, glass, alkali sugar, paper, food, medicine, feed, leather, calcium carbide and organic chemicals, carbonized bricks, carbonized plates and soil improvement, water treatment, gas purification, stone cutting aids, soil stabilizers, A large amount of lime is used in concrete conditioners, chemical reagents, gypsum board caulking coagulants, building adhesive ingredients, calcium alkane sulfonates, pharmaceutical acid stoppers, astringents, hard water softeners, and plastic fibers.
