Many owners of cars came up against a situation when on the way it is necessary to pump up a wheel. It is inconvenient to do it by the manual pump and forces on it leaves much. In such situation the compressor which takes a little place is useful and it can easily be placed in a trunk. In shop the wide range of the similar equipment is presented therefore information on what to choose the car compressor, will be very relevant. There are different types of the similar equipment which differ in the principle of work and also key parameters.
What type of the car compressor it is better to choose?
In most cases the similar equipment has identical filling which the cylinder, the manometer and the motor enters. Today in the market the compressors presented in two forms:
- Membrane. In such equipment the principle of work is based on progress of a special membrane from rubber. The main plus of such equipment – lack of the details creating friction that causes its reliability. Membrane compressors can be repaired, replacing the broken diaphragm. It is possible to refer emergence of difficulties in work in cold season as the membrane becomes rigid to minuses of such equipment. The maximum pressure created by this type of the compressor is 4 atmospheres, so, such equipment is not suitable for cargo cars.
- Piston. In this type of the equipment the operating mechanism is the piston which moves thanks to the compressor motor. Significant plus of this equipment is an opportunity to create big pressure and to have high performance. It is important that the connecting rod of the piston was located on a motor shaft. Saying about how to choose the piston compressor for mounting, it is worth noticing that it is necessary to choose the equipment in which the cylinder is made of quality steel with internal polishing. It is possible to carry to minuses what at essential loads of the technician is overloaded and its work will require a lot of time. It is also worth noticing that the compressor can be hammered into operating time with dust.
How to select the compressor according to the main characteristics?
After it was succeeded to choose equipment type, it is necessary to study possibilities of the device for what it is worth leaning on key indicators.
What to choose the compressor for the car:
- Case material. If the equipment is made of plastic, then it has to be strong to resist to blows, nonflammable and also frost-resistant. Similar requirements concern also hoses.
- Performance. In this parameter it is possible to judge that how many liters of air the compressor in a minute can download. For light cars it is enough also 40 l, and here for trucks and SUVs this parameter has to be 60-70 l.
- Pressure. Novelties in the market of such equipment are capable to make up for pressure equal to eight atmospheres. If the producer specifies bigger value, then it is, most likely, inveracious information.
- Manometer. Thanks to this device it is possible to determine pressure in tires. It can be digital and arrow. It is worth choosing option with the minimum class of accuracy – 0.2. Besides, as for arrow manometers, they because of strong vibrations give inveracious information.
- Way of food. Saying about how to choose the car compressor for pumping of tires, it is worth stopping on this parameter as the equipment can receive food from household network, the lighter or from joint stock bank. The second option, but connection on accumulator terminals more reliable way is considered convenient.
- Useful functions. For example, it is possible to find the compressor which after inflating of a wheel is automatically switched-off. The release valve will allow to lower quickly air from a wheel as necessary. There are options with an additional small lamp, etc.
