Dump truck's cylinder maintenance knowledge
Before starting the dump truck , it is necessary to check if the coolant is sufficient, so as to avoid starting the vehicle in the absence of water. It is not possible to add cold water when the temperature of the engine of the dump truck is too high. This may cause cracks in the cylinder of the dump truck. Because the outdoor temperature in winter will be relatively low, it is necessary to fill the antifreeze well, and put the water clean, so as not to cause the freezing crack of the cylinder. When the dump truck is in use, it needs to be kept at the specified temperature all the time, and there will be no shortage of cooling water, so as to avoid overheating and overcooling of the engine. Before starting the dump truck, the oil level of the oil needs to be checked. The amount of oil in the vehicle needs to reach the scale specified on the oil dipstick. If necessary, it is necessary to replace the oil and add oil in a timely manner.
When the flatness of the dump truck on the flat surface exceeds the limit, the cylinder voltage may cause oil leakage, water leakage, and leakage or ablation due to lack of fastening. During the secondary maintenance of the vehicle, the cylinder can be fully supported on the platform so that the plane between the cylinder and the platform is parallel, that is, two equal high points are found on the diagonal of the four angles. . Move the dial gauges along the platform. The difference between the minimum and maximum degrees on the dial indicator in the plane of Sobe's test is flatness.
The flatness error of the plane on the cylinder block of the dump truck should not be less than 0.05 mm per 50 mm length. The total length of those six-cylinder engines with cast iron cylinders cannot exceed 0.03 mm; the four cylinders cannot exceed 0.02 mm; the engine of aluminum alloy cylinders cannot exceed 0.5 mm. The four cylinders must not exceed 0.3 mm. If the error in the flatness of the dump truck's cylinder surface exceeds the limit, it needs to be repaired immediately. If there is only a slight bulge in the partial position, it can also be smoothed with a fine trowel or rubbed with a stone. If the larger dents can be repaired using machining methods, they can also be repaired using milling or grinding.
Potassium hydroxide, also known as lye is an inorganic compound with the chemical formula KOH. Also commonly referred to as caustic potash, it is a potent base that is marketed in several forms including pellets, flakes, and powders. It is used in various chemical, industrial and manufacturing applications. Potassium hydroxide is also a precursor to other potassium compounds. Potassium hydroxide is used in food to adjust pH, as a stabilizer, and as a thickening agent. This ingredient has been considered as generally safe as a direct human food ingredient by the FDA, based upon the observance of several good manufacturing practice conditions of use. In addition to the above uses, potassium hydroxide is also used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid drain cleaners contain 25 to 36% of potassium hydroxide. Medically, potassium hydroxide (KOH) is widely used in the wet mount preparation of various clinical specimens for microscopic visualization of fungi and fungal elements in skin, hair, nails, and even vaginal secretions,. Recently, it has been studied for efficacy and tolerability in the treatment of warts. It was determined that topical KOH solution was found to be a safe and effective treatment of plane warts.
