(1) Doing a good job of garbage trucks The walking period has a great deal to do with the length of service life of garbage trucks. Doing a good run-in period will reduce the amount of foot parts, improve the surface quality of the parts, improve their wear resistance, and lay a good foundation for prolonging the service life of garbage trucks.
(2) Start the engine correctly Before starting the engine, crank the crankshaft 30 40-40 revolutions before starting. The engine rotates in a cold state
After 2 minutes, the oil is no longer needed to reach each of the Kang's cohesive surfaces. If it is started in a hurry, the engine will inevitably be dry (or semi-dry) in a short period of time.
friction. The longer the stoppage time, the greater the start-up wear, the lower the engine wear, and the greater the start-up torque t. According to statistics, the starting wear accounts for about 50% of the total engine wear.
(3) Keeping the normal working temperature of the engine The normal working temperature of the engine refers to the temperature of the coolant within the range of 80-90°C. At this temperature, the engine parts wear minimal. To do this should:
1. Keep radiator and water jacket clear.
2. Keep enough coolant.
3. Keep the cooling system components and devices working properly.
4. Keep section judo normal.
5. The correct use of warmth device.
(4) Adhere to the car's speed
(5) Prevent overloading of the car.
(6) Preventing engine from detonation combustion
(7) Strengthen the maintenance in the use of automobiles.
Deep Groove Ball Bearing, formerly known as single-row centripetal ball bearing, is the most widely used rolling bearing. It is characterized by small frictional resistance and high speed, which can be used to bear the combined load of radial load or radial direction and axial load, and also can be used to bear the axial load.
The basic type deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. .Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open type means without seal, seal type deep groove ball bearing also have dust seal and oil seal. The dustproof sealing material is sheet metal stamping, only simple to prevent the dust from entering the bearing raceway. The oil-proof type is contact oil seal, which can effectively prevent the grease out of the bearing.
Deep groove ball bearing type:
deep groove ball bearing (60000 type);
Deep groove ball bearing with stop groove in outer ring (60000N type);
Deep groove ball bearing with a dustproof cover and a stop groove on the other side.(60000-ZN type)
Deep groove ball bearing double cover with dustproof cover and with stop groove in outer ring (60,000-2zn type);
Deep groove ball bearing with dust cover (60000Z);
Deep groove ball bearing with dust cover on both sides (60,000-2z);
Deep groove ball bearing with seal (60,000-ls type, 60,000-rz type);
Deep groove ball bearing with seals on both sides (60,000-2ls, 60000-2rz);
Deep groove ball bearing with flange (F60000 type);
Deep groove ball bearing with flange andone side dust cover(F60000-Z type).
Deep groove ball bearing with flange and both sides dust cover.(F60000-2Z).
Application:
Deep groove ball bearing can be used for gearbox, instrument, motor, household electric appliance, internal combustion engine, transportation vehicle, agricultural machinery, construction machinery, construction machinery, roller skating shoes, yo-yo-ball, etc.
