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. Can.

The calcium hydroxide production line adopts a double-shaft stirring structure and consists of a bucket elevator, a special pulse dust collector, a digester, a semi-finished product conveyor, a powder separator, and a PLC control system. The calcium production line has a series of advantages such as environmental protection, automation, and reduction of labor consumption. So do you know the use of calcium hydroxide production line, what should we pay attention to, and how should we ensure the quality of calcium hydroxide in the production process ?

Precautions for the use of calcium hydroxide production line?

1. Calcium hydroxide production line usually works in a high temperature environment, the ambient temperature is high, and the normal working equipment will emit a lot of heat. Therefore, some equipment on the calcium hydroxide production line may generate heat due to continuous work during the production process. We need to prepare some cooling and freezing devices to cool down the equipment when needed to avoid wear and tear of components.

 

2. When working in a high temperature environment, we need to consider the safety and reliability of electricity consumption to ensure that the calcium hydroxide equipment and the circuit of the production line workshop are smooth. The calcium hydroxide equipment can be matched with some electrical equipment , and the detection of electrical equipment can be done in time. If it is found that the line is aging or abnormal, it should be stopped in time.

3. Do a good job in the anti-rust and anti-corrosion measures of the calcium hydroxide production line. Such as long-term rust prevention on exposed metal surfaces, that is, unpainted places: coating and electroplating processes can be used, and corrosion-resistant alloys can be used to prevent rust in the later stage. This work can be started from two aspects, one is to paint the equipment, and the other is to do a good job in post-maintenance and cleaning of the equipment to reduce the probability of rusting of calcium hydroxide equipment.

In cranes, tower cranes, truck-mounted cranes and other lifting equipment, the slewing bearing plays a very important role. It can form a connection between the chassis and the upper structure of the machine, allowing the crane to rotate 360 ​​degrees, while bearing the axial, radial and direction and overturning moment. The open design of the crane slewing ring allows the hydraulic system and other control components to pass through the slewing ring, making more efficient use of the limited space in the hoisting equipment.

As an important “joint” of the crane, the slewing bearing of the crane affects the performance of the crane and determines whether the crane can work normally and efficiently. Therefore, it is very necessary to properly maintain the slewing bearing of the crane.

The maintenance of the crane slewing bearingshould do the following:

 

(1) We must ensure that the mounting support of the slewing bearing has sufficient rigidity and the mounting surface is flat. Before the slewing bearing is installed, the bearing should be destressed to reduce the deformation of the slewing bearing. In addition, when the crane slewing bearing is installed, the contact surface between the bearing and the slewing bearing should be kept clean.

(2) The tooth surface of the slewing bearing should be regularly cleaned of debris and greased.

(3) After the first 100 hours and 500 hours of operation of the slewing bearing, the pre-tightening torque of the bolts should be checked respectively. After that, the preload torque should be checked every 1000 hours of operation. This can ensure the reliability of bolt work and avoid insufficient bolt preload.

(4) During the working process of the crane slewing bearing, it is necessary to pay attention to the changes in noise and slewing resistance moment. If there is any fault, it should be eliminated in time.

(5) When tightening the nut, lubricating oil should be applied to the thread of the bolt and the end face of the nut, and the torque wrench should be used symmetrically and evenly in the circumferential direction, and tighten it several times. The preload torque on each bolt should be approximately the same.

We all know that when some machinery and equipment need to generate excitation force, if the machine itself does not have this function, it needs to add some vibration devices. The vibrating screen needs to use mechanical vibration to screen materials. Therefore, vibration The screen exciter has become one of the important components of the vibrating screen.

When purchasing a vibrating screen exciter, many users generally focus on the quality and performance of the exciter. However, as long as the quality is passed, can the use of the vibrating screen exciter be completely assured? This is not the case. Although the quality of the exciter is the focus of attention, the use of the exciter is correct and reasonable, and it is also an important factor affecting the performance of the vibrating screen. If it is improperly operated for a long time, it is easy to cause the failure of the exciter, thus affecting the normal operation of the vibrating screen. As an old-fashioned vibrating screen exciter manufacturer, Luoyang Haiside Heavy Industry Co., Ltd. shares with you the precautions for the use of vibrating screen exciters, so that more people can learn the correct use of vibrating screen exciters.

The correct use of the vibrating screen exciter is summarized as follows:

1. Before starting the work, check the tightness of all the bolts, and after the initial work for 8 hours, check whether there is looseness and tighten again.

2. Check the oil level in the exciter. If the oil level is too high, the temperature of the exciter will rise or it will be difficult to operate. If the oil level is too low, it will lead to insufficient lubrication and damage to the bearing. Normally, 2/3 of the lubricating cavity should be filled. should.

3. Ensure a minimum clearance between all moving parts and fixed objects.

4. When the load of the vibrating screen starts, it will cause greater pressure on the bearing of the exciter and reduce the service life. Therefore, it is necessary to check the screen surface of the vibrating screen before opening to ensure that the vibrating screen is started under no load, and then start feeding after the vibrating screen runs smoothly. Before shutting down, the feeding should be stopped first, and the machine should be shut down after the material on the screen surface is drained.
