Cleaning methods for ship cranes
1.Vibration cleaning: The parts to be cleaned are placed on the cleaning basket or the cleaning rack of the vibration cleaning equipment and immersed in the cleaning solution. Vibration is based on the simulation of the cleaning equipment to simulate the effect of manual bleach and the oxidation effect of the cleaning solution, and to remove oil.
2. Boiling and cleaning: Assemble the prepared water solution and the cleaned parts into a thick steel plate cleaning tank of suitable specifications, heat it to 90℃, and then put it into the furnace. After that, boil and wash for 3 to 5 minutes.
3. Cleaning: Sprinkle the cleaning solution with the specified working pressure and temperature onto the surface of the product workpiece to remove oil stains. This method has a good cleaning effect and a high production rate, but the equipment is complex. It is suitable for cleaning parts that are not too complicated in appearance and have severe surface oil stains.
4. Special cleaning: The oxidation effect of the cleaning solution combines closely with the ultrasonic oscillation in the cleaning solution to remove oil stains.
5. Scrubbing: Place the parts in a container filled with diesel engine, gasoline or other cleaning solution, and clean them with cotton or a soft brush. This method is easy to operate in practice, the equipment is simple, and the speed is relatively low. It can be used for single and small batch production of parts. Under normal circumstances, it is not advisable to use gasoline for vehicles because it is fat-soluble, which can harm people's physical and mental health and easily cause fire accidents.
Common questions: Based on the causes and characteristics of environmental pollution caused by refined oil products, select the cleaning method to ensure the normal use of all parts, prevent the cleaning or damage of parts, and avoid air pollution and subsequent fouling of parts.
The diesel engine of a ship crane is a component that can convert other forms of energy into mechanical kinetic energy. Its fuel consumption is closely related to the service life of the ship crane, and thus has attracted much attention. So, what are the reasons for the high fuel consumption of its diesel engine? Let's analyze it in depth below.
1.The temperature of the diesel engine is either too high or too low.
2. The piston rod, engine piston and cylinder wall are severely damaged.
3. There are common faults or improper adjustments in the ignition system parts.
4. The cylinder structure is not tightly sealed or the valves are too large.
5. The main volume hole of the carburetor was not adjusted in time.
6. The gasoline pump and fuel injection pump in the diesel engine fuel pump system are not properly adjusted.
The above are the reasons for the high fuel consumption of diesel engines in small and medium-sized ship cranes. For different reasons, we need to do a good job in prevention and handling to ensure that the diesel engine and the ship crane have full normal working efficiency and service life, and do not consume gasoline and diesel resources. In this way, a large amount of expenses can be saved for the company. It can be seen that Reducing its fuel consumption is still crucial in work, and it is necessary to cause concern.
The internal setup and production requirements of ship cranes
1. Check and re-tighten the splicing bolts of each component.
2. The ballast of the track should be compacted to ensure the track surface is level and straight, with a height difference of ±5 centimeters on both sides of the track surface.
3. The operation room should be hung with an operation procedure board, and the gantry crane should be hung with a load limit tonnage board.
4. Check whether there are any broken rubber sheaths or exposed wires on various cables, and deal with them in a timely manner.
5. Check whether the electrical part meets the production requirements and whether short-circuit and leakage protection devices are installed in the main power supply of the operation room.
6. The limit device is excellent and easy to use.
7. Inspection of the running wheel gearbox, lubrication of gear oil and shafts, and restoration of brakes;
Ship cranes not only help us lift materials at a high speed when we are moving and renovating, but are also widely used in various factory operation assembly lines. When we work in an auto parts factory, there are often many components that need to be lifted to a fixed position before assembly. However, some components are very heavy. If we rely on manual lifting, it will not only be time-consuming and laborious, but also difficult to assemble due to instability. At this point, using a ship crane as an auxiliary can make the operation more convenient. First, we fix the crane in place, and then use it to lift the accessories to the corresponding height. In this way, we can assemble the accessories easily and effortlessly. It not only saves time and effort but also ensures a faster and more stable speed.
Performance inspection of ship crane hoisting organization
1. Regulation regulations: Ensure that the relevant organization operates stably during lifting and hoisting operations, maintains accurate posture, and does not cause climbing, vibration, impact, or abnormal expansion of the driver's output power; the lifting, rotation, and lifting mechanism's start-up light emission characteristics are excellent.
2. Adjust the working condition: The elevation Angle of the foundation boom and the heavy boom is 50°. Lift the rated weight under the force in this operation to a height-to-width ratio of one meter and then stop.
3. Adjustment method: Rotate the control joystick to the lifting (lowering) position of the boom. When the lifted object moves slightly, the braking system will be applied immediately. Continuously lift and lower the boom 10 times, accurately measure the accumulated distance of the horizontal movement of the lifted object, and calculate the average posture deviation of each lift and lower of the telescopic boom respectively. The value should comply with the standard value. Otherwise, the reliability and sensitivity of the braking system (galvanized steel wire rope lifting mechanism) or the control accuracy of the condensing static balance valve and secondary coil valve in the hydraulic press control circuit (hydraulic cylinder lifting) should be adjusted.
