What should I do if the vibrating screen discharges?

In daily production, during the use of the vibrating screen, a relatively obvious material conveying is suddenly not smooth, followed by the problem that the discharge is biased in a certain direction. To solve this problem, we must first find out the reason for the deviation of the material, and then find out how to solve the problem of the deviation of the vibrating screen. In response to the above problems, the vibrating screen manufacturer gave us a detailed introduction.

The reason for the deviation of the vibrating screen

High frequency dehydration vibrating screen

1. The vibrating screen has a long working time

The vibrating screen has a large workload and a long working life. For a large linear vibrating screen, due to its heavy weight, if coupled with repeated vibration and strong inertia for many years, some parts of the body will be loose, which will lead to vibration. The angle of the motor changes, so the phenomenon of discharge deviation occurs.

2. Uneven feeding

If the vibrating screen is feeding more or less, it is easy to cause unstable screening accuracy, and because of the more or less material, the force deviation of the material is large, and there is a problem that the discharge is biased to one side.

3. Exciter installation problem

The transportation and screening of materials by the vibrating screen is pushed by the vibration exciter to the material with a fixed magnitude of excitation force in a designed fixed direction. Therefore, if the material conveying is not good, it can basically be judged as a vibration exciter. There is a problem with the installation angle. Under normal circumstances, the manufacturer will perform precise installation, testing, and adjustment before the equipment leaves the factory to avoid the deviation of the excitation force direction, so this problem is generally not the cause of the new machine.

Introduction to the fluidization of powder particles

When the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/s for cement), the friction between the gas and the powder is equal to the weight of the powder, and the powder no longer depends on the flow. The bed supports, at this point they can move freely and flow from high to low, keeping the upper plane of the powder layer horizontal, similar to liquid properties.

If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called the fluidization of the powder. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to make the compressed air form a fine and uniform airflow into the powder layer to fluidize the powder.

Why do concrete mixer trucks turn while walking?

Concrete mixer truck is a special truck used to transport concrete for construction. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete. The power is transmitted to the hydraulic pump, the hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe, and the hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the deceleration and torque increase of the reducer. The handle angle can realize the forward and reverse rotation of the mixing tank and the size of the rotating speed, so as to realize the operations of concrete charging, stirring, stirring and discharging. The concrete mixer truck will always keep the mixing drum rotating during transportation, so do you know why it needs to rotate while walking?

1. Improve the efficiency of use

concrete mixer truck

Concrete mixer trucks involve transportation time, and it takes a certain amount of time for concrete to travel from the manufacturer to the construction site. If the concrete mixer truck walks and turns on the road, the mixing time of the materials can be combined with the time of transportation on the road, which improves the utilization rate of time and improves the work efficiency. Especially in hot summer, the solidification of concrete can be prevented by continuous stirring. After all, for manufacturers and builders, the value of a truck of concrete is still great.

Common oil tank truck faults and solutions

In daily life, oil tank truck is a very common means of transporting dangerous goods, because its transportation objects are mostly all kinds of flammable and explosive oil products, so the safe transportation of oil tanker is the key of every tanker driver. What should be paid attention to, what are the common oil tank truck faults, and how should we deal with these problems? The following is a tank truck manufacturer–CIMC LINYU, to analyze the common oil tank truck faults and solutions.

Oil Tank truck faults can generally be divided into indirect failures and sudden failures. When a failure occurs, we need to first determine the cause of the failure, and then carry out targeted treatment.

1. The oil absorption of the oil tank truck is abnormal

The reasons for the abnormal oil absorption of the tanker are generally: there is no oil in the oil pump; the oil absorption depth is more than 5m; the valve opening position is not correct. To solve this problem, we can fill the oil tank to at least 10L, and adjust the valve to the appropriate position That’s it. If the fuel tank of the tanker cannot discharge oil, it may be an impurity oil discharge pipe. In this case, just cleaning the oil pipe can solve the problem.

2. The oil tank truck cannot absorb oil or absorb less oil

The reasons for the oil tanker not being able to absorb oil or the amount of oil being absorbed are: the suction pipe part is not tightly sealed; the gap of the oil pump is increased. At this time, we only need to make the seal tight, and check and repair the oil pump.

3. The power take-off box of the oil tank truck is abnormal

The reasons for the abnormality of the power take-off box of the tanker are as follows:

(1) The pressure of the car is insufficient, and the power take-off box is not in gear;

(2) The air path is not tightly sealed, and the power take-off box is fooled;

(3) The air chamber is damaged, and the power take-off box is not hooked;

(4) Too little lubricating oil or impurities in the power take-off box;

(5) Wear of power take-off parts

For the above problems, we usually only need to have enough air in the pneumatic power take-off box, so that the reading of the air pressure gauge is above 0.6Mpa, the air circuit is strictly sealed, check the air chamber in time, refuel or update the lubricating oil, dismantle and inspect, clean and replace the worn parts.

Do you know how tractor clutches work?

In modern agricultural production, tractor is a very important machine, and no other machine can replace the work of tractor. Therefore, tractor is widely used in agricultural production at home and abroad.

The use of the tractor clutch can ensure the smooth shifting and shifting of the tractor, and is one of the important accessories to ensure the normal operation of the tractor. With the development of society and the advancement of science and technology, knowledge such as electricity , heat, and information technology has been gradually applied to the machinery manufacturing industry, and the manufacturing technology of tractors has also improved, and has begun to gradually develop towards informatization, which has a great impact on the quality and performance of tractor clutches. Requirements have been further improved. Therefore, the research on the working principle of tractor clutch, how to use it and its maintenance and repair is also the work that tractor manufacturers and users have been doing all the time. Today, I will simply share with you how the tractor clutch works, precautions for use and how to overhaul.

How the tractor clutch works can be understood from its structure and working principle.

tractor clutch

 

The composition and working principle of the tractor clutch

The tractor clutch is mainly composed of four parts, namely: the active part, the driven part, the pressing device and the operating mechanism. The clutch is mainly composed of a flywheel and a pressure plate of the clutch. The flywheel is directly connected to the crankshaft of the engine and is controlled by the crankshaft; the clutch pressure plate is connected to the gearbox, and the transmission force is transmitted to the gearbox through the combination of the flywheel and the clutch pressure plate. The gearbox performs shifting work. In the process of using the clutch, there are two states, namely the combined state and the disengaged state. When the clutch is in the engaged state, the pedal of the clutch is at the highest position, at this time, there is no contact between the release lever in the clutch and the release bearing, and the clutch pressure plate presses the driven plate, thereby transmitting the transmission force to the transmission; while in the disengaged state When the clutch pedal is stepped on, the gap between the release lever and the release bearing is eliminated. At this time, the pressure plate and the release lever move downward under pressure, causing the pressure on both sides of the driven plate to decrease and disappear. The transmission force is transmitted to the transmission, that is, the disengagement state of the clutch.

Precautions for the use of tractor clutches

1. When starting, the clutch pedal should be lifted correctly

When the tractor is just starting, the clutch pedal should be stepped on correctly, and the clutch plate should not be lifted violently, which will make the clutch combination not stable enough and cause great damage to the friction plates. The correct starting method should be “fast, slow, slow”. When the tractor starts, quickly make it in a low gear, and pause to find the contact point at this time, and then change to a high gear to protect the safety of the tractor clutch. , to avoid unnecessary safety accidents caused by clutch damage when the tractor starts.
