There may be many friends who experience high-speed oscillation when using a docking garbage truck. In order to solve this problem, we must first find out what caused the cause of the failure and know the reasons for exclusion and finally solve the problem.
There are six reasons for the high-speed swing of the docked garbage truck.
1 The front wheel alignment angle of the garbage truck is misaligned, causing the front bundle to be too large;
2 The imbalance of the front tire pressure of the garbage truck is too low or the tire is caused by repairs or other reasons;
3 The front spoke deformation or the number of tire bolts are not equal;
4 loose parts of the drive system components;
5 garbage truck drive shaft bending, dynamic imbalance, front axle deformation;
6 Vibration absorber failure, inconsistent rigidity of the front leaf spring; deformation of the frame, loosening of the rivets, or deformation of the front shaft.
Butt-type garbage trucks at high speed vibration diagnosis and troubleshooting:
1 There are usually two cases of high-speed runout. One is that as the speed of the garbage truck increases, the oscillating movement becomes stronger; the other is that during a certain period of high vehicle speed, the oscillates and causes the steering wheel to shake. In making judgments, the drive axle is first erected, the front wheel is plugged with a safety plug, the engine is started and the high speed gear is gradually changed, so that the drive wheel reaches the final test-pivoting speed. If both the vehicle body and the steering wheel appear to shake, this is the vibration caused by the garbage truck drive system. Because the front axle front axle is at a standstill at this time, if the final trial oscillation speed is reached and the garbage truck does not appear to shake, the reason for the vibration is that there is a fault in the front axle part of the garbage truck.
2 Check whether the front wheel alignment angle and the front wheel meet the requirements. If the misalignment should be adjusted immediately.
3 Set up the front axle to test the wheels, check the wheel static balance and whether the tire is deformed too much. If necessary, carry out comparative tests of good docking garbage truck wheels.
Through the above introduction, I believe that everyone has a certain understanding of how to solve the high-speed swing failure of the docking garbage truck, clear the cause of the failure, and master the elimination method, I believe that this type of failure can be easily handled again. I hope my sharing can help you.
Standard Plastics <80℃
Some of the plastic variety that people will produce large, low price, wide use and wide influence is called standard plastic.Its connotation often changes with the development of time and science and technology.Important standard plastics are polyethylene, polypropylene, polyvinyl chloride, polystyrene and other varieties
standard plastics including polyethylene, polypropylene, polystyrene, PVC, acrylic - butadiene - styrene), poly (methyl benzene acid methyl ester and amino plastics and so on, its production accounted for more than 90% of the whole plastic production, so it is also called the large plastic varieties.
Merits and demerits
Compared with wood, metal, cement, glass and other materials, standard plastics have the following advantages and disadvantages.
Advantages: (1) easy to form, high degree of freedom of design;(2) easy coloring;(3) stronger than metal;(4) lighter weight;(5) easy to modify, easy to obtain required performance;(6) good electrical insulation;(7) good water resistance and no rust;(8) good chemical resistance;(9) production consumes less energy than metal;(10) as long as the waste plastics are treated well, the environmental damage and pollution will be less than other materials.
Disadvantages: (1) poor weatherability, especially in ultraviolet light, aging easily under uv light;(2) generate static electricity;(3) large thermal expansion coefficient and poor dimensional stability;(4) low surface hardness, easy to produce scratches;(5) poor durability and poor environmental stress cracking.
But with the continuous development of blending technology progress, as well as the standard polymer high-performance achievements, some of its insufficient gradually improved, broadens the application field of standard plastic, made of plastic in the position in the national economy more and more important.
Standard plastics has excellent performance, variety and versatility.Standard plastics can replace metal materials, cellulose materials and silicate materials with three traditional materials, and as the most powerful competitor of traditional materials.Standard plastics has been widely used in agriculture, light industry, textiles, electronic appliances, machinery, building materials, packaging and transportation and other departments, profoundly influences the whole development and the progress of science and technology, industrial and agricultural production in social development and national economic development, people's material and cultural living standards improve all aspects such as occupies very important position.
The purpose of standard plastics can be covered in the following aspects:
(1) Agriculture: various kinds of agricultural film, sheet materials, holding irrigation pipes, sprinkling irrigation pipes, fishing nets, breeding boxes, floating materials.
(2) industry: due to the electrical insulation of plastics, standard plastics are already used in the electrical industry to make insulating materials and packaging materials.Manufacturing parts and shells in electronic and instrumentation industries;Transmission gears and bearings in the mechanical industry;Chemical industry of various anti-corrosion containers, pipes, slots, tanks, etc.
(3) construction industry: Plastic doors, Windows, ceilings, floor leather, plumbing and pipe fittings, gas pipes and fittings, etc. are made from traditional materials such as wood and metal.
(4) Packaging: Various woven bags, packaging films, composite films, hollow containers, revolving boxes, corrugated boxes, packaging belts, foam plastics, etc.
(5) daily supplies: all kinds of plastic toys, toothbrushes, soap boxes, raincoats, tableware, utensils, slippers, etc.
(6) medical and equipment industry: all kinds of artificial organs, medical use infusion bags, one injection supplies, degradative medical materials.
(7) electric appliance industry: All kinds of office appliances and household appliances insulation, heat preservation, anticorrosive, moisture-proof housing, resistance to the tang, precise military components and so on.
Divisor in the above areas,standard plastics apply more extensive, at present, some standard plastics by modification to expand the application field, in the defense cutting-edge industry, transportation and aviation industry used as structural materials a lot.
