1, because the winter temperatures are basically below zero, and the activity of the electrolyte in the battery of the mobile sales vehicle will be relatively low compared to other seasons, and the performance of the electricity storage will also be worse. . In this case, the mobile vending truck driver needs to check the condition of the battery power periodically. When the vehicle is turned off, it is important not to forget to turn off the lights or air conditioners, so as to avoid a situation where the mobile vending truck battery is depleted. appear.
2. In addition to the fact that the generators of mobile vending trucks in the winter have difficulties in starting up, in addition to the situation caused by the loss of the battery of the vehicles, there may be a serious product in the intake area of ​​the engine of the mobile vending truck. Because of carbon, the drivers must clean the throttle of the vehicle before seeing the winter, and reduce the occurrence of these conditions. Because the oil will have a higher viscosity at lower temperatures, it will also increase the resistance of the engine. This is also one of the reasons why the mobile vending engine starts to suffer. So in the winter, you should change the oil of the vehicle into an annual Thin engine oil.
3, the mobile vending engine's temperature rises in the winter is relatively slow, or the temperature does not go up, and the warm air is not warm, this is a relatively common problem. The place where most can be reflected is when the water temperature rises and traffic jams occur while waiting for the red light. However, once the mobile sales truck starts to run, the temperature will begin to drop again. The main reason for this situation is that the thermostat has a malfunction. It has always been maintained in a large cycle and can be changed after replacing the new thermostat.
When the mobile vending engine is started after the cold car is started, if the vehicle's engine has a rotating speed or an unstable idling condition, the causes of this failure include the following: The ignition system of the mobile vending engine malfunctions, the intake valve The back, as well as the excessive carbon deposition in the intake pipe, the failure of the fuel supply system, the damage to the ignition ring, and the like.
Return oil filters
Describe:
The return oil filters are located on the return pipeline of the system, the function is to capture the contaminants produced or intruded in the system before returning to the tank. So it's the most effective and important filter for controlling the concentration of pollution in the system.
The return oil filter is mainly installed on the return pipe road of the hydraulic system. Various kinds of dirt such as abrasive particles produced by various hydraulic components in the working process can be intercepted by setting the oil filter of the return oil pipeline to avoid returning to the fuel tank again. Inhaled again by a hydraulic pump. The allowable pressure difference of the oil filter in the return pipeline is 0.3 ~ 0.5mpa. according to the different pressure level. The accuracy is determined according to the requirement of oil contamination.
Characteristics:
The material of the filter elements are the chemical fiber, filter paper, wire mesh and line-gap types. The chemical fiber filter is more effective than paper filter, and the precision is high. It is difficult to clean the chemical fiber filter and paper filter element after blocking, so it is necessary to replace the filter element. The return oil filter is equipped with a differential pressure signaling device. When the pressure difference between the inlet and outlet of the filter due to the clogging of the filter element is up to 0.35mpa, the switch signal should be issued, and the filter element should be cleaned or replaced at this time. The filter core adopts a new type of
chemical fiber Filter Material, which has the advantages of high filtration accuracy, large oil flow capacity, low original pressure loss, large amount of sewage absorption and so on. The filter accuracy is calibrated with absolute filtration accuracy. The filtration ratio 3, 5, 10, 20 > 100, the filtration efficiency ≥ 99 ~ (99), is in accordance with the ISO standard.
