One is oil dripping lubrication, which uses an oil cup to contain some lubricating oil and drops oil through the oil pipe to the gap between the inner and outer link plates at the loose side. The other is to lubricate the palm oil chain by means of oil injection. During operation, an oil pump is required to continuously supply oil to the chain through an oil pipe, thus playing the role of lubrication and cooling.

It is also one way to add lubricating oil to palm oil chain by manual method, using oil pot or brush regularly. In addition to the above three lubrication methods, oil bath lubrication or splash lubrication can also fully and effectively help palm oil chains to reach the lubrication state. A sealed transmission case is adopted. Part of the former chain and sprocket are immersed in oil, while the latter is splashed with oil by a larger diameter oil slinger.

Chain pollution: such as paint pollution and special grease pollution are not easy to remove in general alkaline degreasing solution. At this moment, it is necessary to use special solvent to remove or use incineration method, sand blasting method, etc. What is good for conveying chain, which increases cost and difficulty. In addition, the removal of welding slag such as welding touch is also appropriate and important. In order to reduce friction and wear between friction pairs and reduce friction resistance, all wear-reducing substances can be used as lubricating materials. There are many kinds of lubricating oil, grease, solid lubricant, etc. When selecting lubricant for chain transmission, the coordination among lubrication form, ambient temperature and chain specifications must be considered. Generally, high-quality mineral oil with stable chemical properties is used, and the one with pure composition, no oxidation and no impurities is the best.

There is a strict requirement in the production process of the conveyor chain, which is to prevent dust from entering and grease from flowing out of the hinge, so the chain must undergo strict pre-lubrication. Formally speaking, there are two types of conveyor chain: roller chain and sleeve chain. Most of the chains used in the engine are sleeve chain structures. The chains used outside the engine are transmission chains used to drive the rear wheels. Most of them use roller chains.

Judging from the current situation, there is no problem with the chemical properties of the conveyor chain. The key lies in its shockproof capability and noise. If the noise produced by the conveyor chain can be effectively reduced and the shockproof capability can be increased, it will play an important role in the transportation field.

1. Palm oil chain rusts due to lack of antirust treatment.

In the production process of palm oil chain, operators did not carry out the anti-rust treatment in strict accordance with the production requirements and did not adopt anti-rust packaging. Once it comes into contact with corrosive liquid and gas, corrosion will occur.

2. The palm oil chain rust is caused by the substandard quality of antirust oil.

Even though products such as antirust lubricating oil and clean fire oil have been applied to palm oil chain, if the quality of the products does not meet the technical requirements, it will be in vain and will also cause the corrosion of palm oil chain.

3. Corrosion of palm oil chain is related to chain materials.

In order to reduce the production cost of palm oil chain, some manufacturers choose unqualified materials, such as high content of nonmetallic impurities in the steel, which will reduce the anti-corrosion ability of the formed chain itself and lead to similar defects.

4. Palm oil chain corrosion is related to the operating environment.

When palm oil chain works in poor conditions for a long time, they will think that the content of harmful substances is too high, or the space is too small to carry out antirust treatment, thus causing adverse effects on the chains.

In addition, in this case, the stress on one side of the leaf chain bearing will become larger, which is easy to cause damage due to heating. Even if it is not damaged, it will form a larger gap in a short time. Once there is a large gap between the bearings, the straightness of the countershaft will be damaged.

Therefore, it is only necessary to do a good job of protection in order to prolong its service life and save the input cost for users. Leaf chains are combined with wheels with cogged buckle teeth to engage blocks with the pitch on chain links or cables, so errors can be avoided if the two can be produced together.

When the leaf chain is used in humid or high temperature environment, corresponding protection measures must be taken, otherwise, not only the leaf chain's due function cannot be fully exerted, but also its service life may be shortened.

2. The old combine chains cannot be mixed with some new combine chains, otherwise it will easily cause impact in the transmission and break the combine chains.

3. In the work of the combine chains, remember to fill the lubricant in time. The lubricating oil must enter the mating clearance between the roller and the inner sleeve to improve working conditions to reduce wear.

4. There should be no skew and swing on the shaft when the combine chains is installed. In the same transmission assembly, the end faces of the combine chains should be in the same plane. When the center distance of the combine chains is less than 0.5 m, the deviation of 1 mm is allowed to be more than 0.5 m when the center distance of the combine chains is 0.5 m or more. However, it is not allowed to have friction combined with the side of the combine chains. If the two wheels are too large, the chain is prone to de-chaining and accelerated wear. Care must be taken to check and adjust the offset when replacing the combine chains.

5, the tightness of the ccombine chains should be appropriate, too tight to increase power consumption, the bearing is easy to wear too loose and the chain is easy to jump and unchain. The degree of tightness of the combine chains is: lifted or pressed from the middle of the combine chains, and the center distance of the two combine chains is about 2% to 3%.

6. The new combine chains is too long or stretched after use. It is difficult to adjust. The link can be removed, but it must be even. The links should pass through the back of the combine chains, the locking tabs are inserted outside, and the opening of the locking tabs should be oriented in the opposite direction of rotation.

There are two main forms of industrial chain failure: one is failure caused by wear and tear; One is failure caused by fatigue.

Wear failure is the most common and obvious form of the industrial chain. There are many reasons for this failure. The main reasons are poor chain material and improper operation of workers. The most easily worn parts of the chain as a whole are sprocket and pin shaft. The wear of these two parts is mainly due to insufficient local lubrication, so in order to avoid this phenomenon, operators should pay attention to check the lubrication effect frequently, add lubricating oil in time, check whether there is abrasive in the lubricating oil or change the lubrication method. After the sprocket of the industrial chain is slightly worn, the sprocket can be reversely installed so that the less worn side faces the chain. In addition, if the use environment is harsh or the lubrication seal is not good, the hinge will be worn. Once the chain hinge is worn, the chain-link will become longer, which will easily cause tooth jump or chain release during operation, reduce the service life of the chain and accelerate the chain failure.

Let's talk about the failure of industrial chains caused by fatigue. At present, most factories in our country have workers rest and machines do not rest. Therefore, industrial chains are often overused and fail due to fatigue failure. That is to say, the chains bear excessive load during operation, resulting in uneven stress and easy breakage or extrusion. For this kind of situation, our chain factory can only solve it by strengthening parts.

In addition, in the process of low-speed and heavy-load transmission of industrial chains, overload breaking is also a common failure mode. Under certain service life, poor lubrication and sealing of the chain, or bad working conditions, will accelerate wear, leading to a significant reduction in the limit power, resulting in the failure of overload pull-off.

The storage of the combine chains is also crucial for prolonging the service life. When these parts are not used, they cannot be placed anywhere, otherwise, the quality of the chain will be easily damaged. When storing these products, do not store them in damp, hot and chemically corrosive places. Avoid storage in a humid environment, because the combination chain in a humid environment, the surface covered with water and oxygen produce chemical reaction to form rust, which damages the quality of the chain and further affects the sales. Do not place the chain in a place with too high a temperature or in a place with direct sunlight. If the sunlight is direct, the temperature of the stool surface of the chain will rise, expanding with heat and contracting with cold, thus changing the physical characteristics of the chain and causing damage or tooth drop during use. Placing the chain in the corrosive chemical environment will seriously corrode the surface of chain sprocket. Most of the chains commonly used in corrosive environment are galvanized chains or nickel-plated chains. Therefore, the chain must be stored in accordance with reasonable regulations so as to prolong the service life of the chain and reduce the expenses of the manufacturer.

1. One of the most important reasons for chain slipping is that the friction force between the chain and the conveyor belt is not enough. This phenomenon is mainly caused by water or humidity in the environment in which the chain is used. For this reason, we can take measures to add some rosin powder to the roller, but we should pay attention to not operating by hand in the process of adding rosin powder to avoid safety accidents.

2. The chain tension is too small, which is one of the reasons. It usually occurs at startup. The best solution is to adjust the chain tension device to increase the initial tension.

3. The speed of the conveyor in the conveying process is too fast, which will cause the conveying chain plate to slip. As long as we slow down the starting chain, we can effectively overcome the slip phenomenon.

1. The chain is tired and invalid

Assuming that the lubrication conditions are relatively good, but also a relatively wear-resistant heavy roller chain is basically due to fatigue damage when it fails. Due to the tight and loose edges of heavy roller chains, the load borne by these parts will also change. When the chain rotates, it will stretch or bend due to stress. Due to various external forces, cracks will slowly appear on various parts of the heavy roller chain. The cracks will slowly grow larger and fatigue and fracture may occur over time. Therefore, when consuming heavy roller chains, various measures will be taken to improve the strength of the parts. In other words, chemical heat treatment is applied to make the parts appear carburized, and shot peening is also used.

2. The cohesion strength is damaged

When the heavy roller chain is used, due to the load, the joint between the outer chain plate and the pin shaft, as well as the inner chain plate and the sleeve, may loose during use, causing the eyelets of the chainplate to wear out, and the length of the heavy roller chain will increase, presenting failure. Since the chainplate will fall off when the riveted center of the pin shaft head of the chain is loosened, and the chain-link may fall apart when the center of the pin is sheared, the heavy roller chain will eventually fail.

3. The chain will fail due to wear in use.

Assuming that the heavy roller chain materials used are not very good, the chain will often fail due to wear. The length of the chain will increase after it is worn out, and it is likely that there will be teeth jumping or chain dropping when in use. The wear of the chain is usually in the center of the outer link. If the pin shaft and the inside of the sleeve show wear, the gap between the hinges will increase and the length of the outer joint will also increase. The distance between the inner links is usually affected by the bus bars on the same side between the rollers. As it is not normally worn, the length of the inner links is not normally increased. If the length of the heavy roller chain is increased to a certain range, it may be broken, so its wear resistance is very important when consuming chains.

In addition, the performance of the heavy roller chain will be affected by gluing, static tension breaking, frequent starting, braking and other actions in the application process, which may lead to failure of the heavy roller chain.
