Sprinkler winter routine maintenance knowledge
There are two main aspects of winter maintenance of sprinkler vehicles. One is the mandatory maintenance provided by your brand's garage maintenance station on a regular basis. On the other hand, it is up to the owner to find out the problems early in daily use and make some routine maintenance. Only by doing this can the sprinkler extend the service life and safety of the vehicle. Improper maintenance or improper use of the sprinkler can cause vehicle breakdown and pose a safety hazard. Therefore, when you use a water truck, you must carry out careful and careful maintenance.
Dear user friends, please read carefully the manual of the sprinkler that comes with your car after you purchase the sprinkler, and follow the instructions on the manual for use and maintenance. Only in this way can your water truck stay in good condition at all times.
The following brief introduction to the maintenance of common sense after the use of the vehicle to a total reference.
First, the sprinkler car engine oil check
First park the sprinkler on a flat surface. Only in this way can the oil amount of the oil leveler be checked correctly. If the oil is within the two (F) and (L) markings, the oil is in the normal range, and if the oil is lower than the (L) position, it is not enough. The specified model should be added, and the fluid level after adding the oil can not be higher than the oil gauge (F).
Second, sprinkler engine antifreeze liquid level inspection
Note that when the engine is at a high temperature, you must never open the radiator cover, otherwise you may get burned by spilled coolant or high-temperature steam. After the engine is cooled, check that the liquid level of the antifreeze is between full and low. If it is not enough to add antifreeze as required, you cannot add other liquids. Otherwise, it will freeze the engine of the sprinkler and corrode the engine in the winter. .
Third, the brake fluid surface inspection
The braking of the sprinkler is very important because it often works in the downtown area of ​​the city, so we often check that the brake fluid is not enough. If it is found that the brake fluid is not enough, we must first check the brake system for possible leaks, timely repairs to the repair station, and add enough brake fluid, pay attention to adding the same type of brake fluid, so that the sprinkler car safe driving .
Fourth, the clutch master cylinder liquid level inspection
The fluid level of the clutch is between the high and low fluid levels, which is normal. If it is lower than the standard line, it may be damage to the main pump or the sub-pump. In the running state of the engine, it will be difficult to file or unable to file. Please visit the nearest service station immediately.
Fifth, battery maintenance inspection
Check whether the battery is firmly fixed and the electrolyte should be between the upper limit and the lower limit. When close to the lower line, add electrolyte or distilled water to the high position line in time. Keep positive and negative battery cables in good contact, and keep the battery clean and dry. Vehicles that have been placed for a long time must take off the positive and negative cables of the battery. After about half an hour or so of reconnecting and starting the engine, about 20 minutes later, if the battery is obviously insufficient, charge it in time.
Sixth, tire inspection
The tire pressure should be checked at room temperature every month. If it is lower than normal, the tire pressure should be replenished in time. The pressure cannot be too high or too low, otherwise it will affect the safety of driving. Check the cracking condition of the tire. When there is a safety hazard, replace the tire in time. When selecting tires, they should be the same type.
Seven, belt inspection
When starting the engine or driving the vehicle normally, the belt sounds. In one case, the belt is not checked and adjusted for a long time. Adjust it according to the normal standard. Another situation is the aging of the belt and it needs to be replaced.
Eight, air filter inspection
Over-dirty air cleaners can cause poor engine operation, excessive fuel consumption, and damage to the engine. When inspecting air cleaners, if there is less dust and lesser clogging, use high-pressure air to blow it from the inside out and continue to use it. Dirty air filters should be replaced in a timely manner.
Nine, spark plug inspection
The normal spark plug insulating ceramic is intact. There is no crack leakage phenomenon, spark plug gap 0.8 + -0.0mm discharge, the spark is blue, strong. If abnormality is found, adjust the gap or replace the spark plug.
Ten, check the fuel filter
If it is found that the fuel supply is not smooth, check whether the fuel filter is clogged. If the foreign matter is blocked, replace it in time.
Since the SMC is a fast curing system, the quick closing of the press is important. If the press is closed too slowly after feeding, it is easy to appear pre-cured patch on the surface of the product, or it may be short of material or oversized. While achieving rapid closure, the mold closing speed should be carefully adjusted at the end of the press stroke to slow down the closing process and facilitate the exhaust.
Molding Pressure The SMC forming pressure varies with the structure, shape, size, and degree of SMC thickening. The simple shape of the product requires only 25-30Mpa of molding pressure; the shape of the complex product, molding pressure can reach 140-210Mpa. The higher the degree of SMC thickening, the greater the molding pressure required.
The size of the molding pressure is also related to the mold structure. The forming pressure required for the vertical parting structure mold is lower than that of the horizontal parting structure mold. A mold with a smaller gap requires a higher pressure than a mold with a larger gap.
