RV tourism is a new type of travel with RV as the carrier. The development situation of caravan tourism is very good, but there are many problems inevitably. The following editor will tell you some first aid methods for faults in RV travel.
What to do if the caravan leaks water?
In most cases, the failure of the pressure relief valve is the main cause of the water heater leakage. However, according to the law of thermal expansion and contraction, the volume of water increases after heating, and the space of the water heater is not enough, and the water will overflow from the thermal reaction valve (TPR) .
The solution to this kind of water heater leakage is very simple: first, turn off the water heater, cut off the power supply or close the air valve; then, close the external water inlet of the caravan and turn off the water pump; then turn off any faucet in the caravan Open; after the water in the water heater has cooled, carefully pull the thermal response valve lever. Let the water flow out; after the water is no longer overflowing, close the thermal reaction valve; finally turn off the faucet to gradually restore the water pressure. After finishing, turn on the water heater again, and the water leakage situation will be obviously improved. After opening the valve and turning on the faucet, the pressure above the water heater tank increases, and after the water is heated and expanded, it squeezes the accumulated air without directly overflowing.
What should I do if the RV brakes fail?
It is also possible for the brakes to fail after driving in the wild for a long time! Brake failure may be caused by insufficient maintenance of the brake system or improper operation while driving. This is a very serious and dangerous failure, and the precursors are often difficult to detect, it all depends on the on-the-spot reaction!
Try to use natural obstacles to stop the car to escape danger, or reduce the speed of the car by tightening and releasing the handbrake several times. In case of a brake failure when going uphill and you need to stop on a half-slope, you should keep the forward low gear and tighten the hand brake, and the car crew should quickly block the wheels with stones and other objects to prevent back slipping.
In the face of the above failures, the basic methods of first aid can be replaced, blocked, repaired, tied, broken, shortened, reduced, and replaced. In specific applications, in order to achieve the purpose of first aid, when several methods can be used for a fault, the fastest, most economical and safest method should be selected and used.
Its specific method is described as follows:
If conditions permit, and on the premise of ensuring reliable emergency driving after repair, the “repair” method should be adopted. If the connecting rod bearing is burnt out, after repairing welding with solder, use a knife to repair and scrape normally and then it can be used. This belongs to cultivation.
When a part is damaged and cannot drive normally. It can be replaced by parts that do not affect the running of the car, or replaced by self-made parts by taking materials on the spot. For example, use belts and backpack straps to make homemade fan belts to replace damaged fan belts.
That is, oil leakage, water leakage, and air leakage are blocked. If the fuel tank leaks, use epoxy resin to glue or smear it; if there is a perforation, you can use a wooden plug to block it, and if necessary, use iron wire or rope to tie it firmly.
It is the supplementary method. When a part is damaged and lost, or when the fit gap is too large, it can be considered to add a part of other parts for emergency repair. If the oil pipe is damaged and cannot be blocked, the damaged part can be cut off. Cover both ends of the oil pipe with rubber pipes to make it conduct.
It is the bandaging or binding method. When there is a fault that needs to be tightened and restored, consider using ropes, iron wires, wooden sticks, etc. to stick and bind. If the steering tie rod breaks, stick it with a wooden stick and tie it with wire, and keep it in use after both ends are tightened.
The circuit or air circuit that is about to be damaged is disconnected. If a certain wire is grounded and discharged, it is difficult to eliminate it for a while. When air leaks in the system and affects the work of the braking system, you can disconnect this air circuit to ensure the effective braking of the other air circuit, etc., which are disconnected first aid.
Generally speaking, for circuit parts, if a certain component in the circuit is damaged, it can neither be repaired nor replaced. Under the premise of allowing, it is a short circuit method to connect them in a short circuit. For example, the thermistor in the ignition coil is damaged. , You can use the short circuit method to ensure the normal operation of the engine.
The damaged parts should be removed under the premise of not affecting the driving. If the generator is damaged, it can be removed, and the path between the regulator and the power supply can be cut off. Only the battery can supply power to the ignition system. If the valve is broken, the valve adjustment screw of the cylinder can be removed to keep the valve closed, which is equivalent to subtracting the work of one cylinder.
It is to change spare parts, and bring as many spare parts as possible when leaving the car for emergency replacement. Although this method is simple, it is limited after all.
