1. What are the main causes of oil spillage in tank trucks? Parts (such as side covers and thin-walled parts) are deformed at the joint surface and the housing is damaged, causing the lubricating oil to leak out.
2. After the plugs and check valves are blocked, due to the pressure difference between the inside and outside of the case, oil leakage may occur at weak sealing points.
3. The product (accessory) is of poor quality, material, or process; there is a problem with the structural design.
4. Improper assembly of high speed, with unclean surfaces, gasket damage, displacement, or failure to install according to operating specifications.
5. After long-term use, the sealing material wears too much, aging, deformation and failure.
6. Too much oil, too much oil or wrong oil.
7. Unstable tightening nuts, slip wire breaks, loose locks, etc., cause work failure.
Second, prevent oil tanker oil leakage and treatment methods
1. Avoid check valve, vent valve blocked. Due to the pressure difference between the inside and outside of the enclosure, it often causes oil leakage in the weak sealing area. Therefore, vehicles need to be regularly inspected, dredged and cleaned. As a result, the temperature in the enclosure rises, oil and gas fill the entire space, and emissions do not go out. As a result, the pressure in the enclosure increases and the lubricant consumption increases and the replacement cycle shortens. After the engine's ventilation system is blocked, the piston's movement resistance is increased and the fuel consumption is increased.
2. The joint nut of the vehicle is often disassembled and assembled, and it is easy for the slip wire to break and loosen, which can cause oil leakage. Properly solve all types of oil pipe joint seals. Replace the union nut, use a grinding method to solve the cone seal, make the nut tight and solve the seal.
3. Avoid hub throwing oil. Therefore, use the "cavity lubrication method (that is, the amount of lubrication)" to clear the ventilation hole. Wheel hub bearings and cavity too much lubricating oil, or its oil package is not properly equipped, poor quality and aging failure; brakes frequently caused by the hub temperature is too high; axle nut loose, etc. will cause the hub to throw oil.
4. Such as the oil pan or valve cover, due to the large contact area and difficult to compact, resulting in oil spills. Pay attention to the role of cushions. The gaskets between the stationary parts of the car (such as the joint end face, the housing, the cover gasket, the planar cover plate, the end caps, etc.) function as a leak-proof seal. If the materials, production quality, and installation do not conform to the technical specifications, the leak-proof function of the seal will not be achieved, resulting in accidents.
5. If the oil sump screw plug is not tightened or loosened, it will easily cause the loss of oil, and then a machine damage accident of “burning and holding the shaft†occurs. In addition, all types of fastening nuts on the vehicle must be tightened according to the specified torque. If the pressure is too tight, the gasket will leak; if it is too tight, it will cause the metal around the screw hole to bulge or screw the screw to cause oil leakage.
6. The oil seal must be replaced on time. If the improperly installed parts of the vehicle will cause discrepancies in the journal and oil seal edges, the oil spills will occur. If it is found that excessive use of the oil seal over time will affect the leakage of the vehicle and lead to oil leakage. Therefore, Chu Sheng Company warmly reminds you that this phenomenon should be promptly replaced.
Product introduction
Steel Bending Machine, one of steel reinforcement processing machinery.
The working mechanism is a horizontal working disk rotating on the vertical axis. The steel bar is placed in the dotted line position in the diagram. The supporting shaft is fixed on the machine tool.
For bending steel bars of various diameters, there are several holes on the work plate to insert the bending pin shaft, and the center pin shaft of different diameters can be replaced accordingly.
Advantages of characteristics
Applicable to all kinds of round steel, carbon steel, screw steel.
It has strong operability, high working efficiency, convenient Angle adjustment and neat bending
Operation procedures of steel bending machine:
1. Check whether the mechanical performance is good, keep the working table and bending machine surface level;
And prepare various spindle tool blocks.
2. According to the requirements of the diameter of steel bar and bending machine, the core shaft, forming shaft, iron shaft or variable structure shall be installed. The core shaft diameter shall be 2.5 times of the diameter of steel bar.
Check the core shaft, block and turntable shall be free of damage and crack, and the protective cover shall be tightly fixed and reliable, and the operation shall not be performed until it is confirmed that the air machine is running normally.
Iv. During the operation, insert the bend end of the steel bar into the clearance provided by the turntable for fixation, and fix the other end close to the fuselage and press it with your hand to check the fuselage fixation.
The side that actually holds the steel bar can be moved.
It is strictly forbidden to change the spindle, change the Angle, adjust the speed and so on.
When bending steel reinforcement, it is strictly forbidden to process steel reinforcement diameter, root number and mechanical speed beyond the mechanical specification.
When bending high hardness or low alloy steel bars, the maximum limit diameter shall be changed according to the mechanical nameplate, and the corresponding mandrel shall be replaced.
8. It is strictly forbidden to stand in the working radius of the bending steel bar and the unfixed side of the fuselage.
Curved semi - finished products should be stacked neatly, curved hooks should not face up.
When the turntable is turned, it must be done after it has stopped.
X. completion of operation, cleaning of site, maintenance of machinery, power off lock box.
