Prince beam roof panel design requirements: load pump low pressure water system, installation 80QSB-60 sprinkler pump, pump flow 60m3 / h, on both sides of the bottom three curved configuration before Prince beam gun, rear working platform installation of fire water cannon, the vehicle the lower sides of the mounting pressure sprinklers, the upper mounting lotus spray and other functions; the problem: the total light switch common faults, fault lights master switch is damaged or not working properly. Water entering the master switch inside the lamp, causing corrosion of the contact arm, elasticity decreases, resulting in poor contact. Copper rings are grease stains, resulting in contact with the copper ring is bad. Method to check the power supply connected to the lamp post master switch has power. Without electricity, is a power line failure; then the total light switch knob to the desired position, check the next column it should be turned on whether there is electricity. Without electricity, it proved to be a master switch internal fault lamp, replace the lamp master switch. Prince girders open gripping the steering wheel.

In addition, nitrogen oxides, etc., then the color of the exhaust gas may be black, blue or white cab processes, that is to say not exhaust smoke color For regular gasoline, the normal exhaust fumes should be no significant but Shangcuan cylinder lubricating oil, exhaust blue;... incomplete combustion, the exhaust is black oil mixed with water, white exhaust from overheating usually occurs . the engine, transmission, drive axle main gear, differential and brake assembly, etc. For example, engine overheating, mostly for cooling problems, is the lack of coolant or the pump does not work; transmission and drive axle overheated, mostly for lack of lubricants due; The brake overheating, mostly for brake shoe does not return the above phenomenon can sometimes be caused by a dashboard warning light directly reflected the need to observe the driver while driving the cab accelerator, you can manually test appearance Temperature Prince mutation cab working conditions, working conditions refers Prince cab suddenly appeared abnormal phenomenon, which is more common failure symptoms such as: difficulty in starting the engine suddenly stalled and then can not even start; the engine running. sudden decrease in power, driving weakness; moving suddenly brake failure or deviation cab cylinders, or even failure and other symptoms of this failure is obvious, it is easy to detect abnormal noise Prince cab appeared in the process of moving abnormally. sound, a car failure "alarm." In moving suddenly abnormal noises, as Prince cab car driver should be aware of a problem, you should immediately stop checks, must not let the vehicle "sick job."
