As we all know, is a small gasoline engine using gasoline as fuel and power is less than 30kW, non Road (excluding motorcycle gasoline engine) small gasoline engine, the corresponding machinery widely used in rural water pumping, irrigation, power generation, threshing, plant protection, garden pruning etc.. If you want to use it well, you have to choose a good gasoline engine to see how we give you the choice.
One, look at the sign
1. See whether there is a nameplate on the small gasoline engine, and whether the nameplate is marked with the name of the product model, the factory name, the site, the date of the factory and so on.
2, see whether there is a product certificate, or not to fill in the product model, number, factory date and other information.
3, see if there is a production license number. The small gasoline engine is the product of the production license management, and the production license number should be marked on the product and related technical documents.
4, look at the random documents of the small gasoline engine, such as the instruction manual, the three package certificate and so on. Are the product names, specifications, models, etc. consistent with the contents on the nameplate?
5. Look at the parts and parts. The box of the product of regular production enterprise is produced by special production plant (marked), and there is production date on carburetor, and there is a certificate and production date on cylinder head, muffler and magneto.
6, see whether the power is reasonable. The power index directly indicates the working capacity of gasoline engine, and the work capacity is limited by the size and displacement of its cylinder. When the cylinder size and its displacement are constant, the maximum power output will be fixed, even if there is a deviation, it will not be too large, usually no more than 10%.
Two, look at the safety protection and warning of the whole machine
The safety protection devices and warning signs can effectively guarantee the personal safety of the users. They belong to the national mandatory standard. Whether they meet the requirements is one of the important ways to judge the fake and shoddy small gasoline engines.
1, look at the starting jaw small gasoline engine (wheel), rotating flywheel or output shaft exposed is installed to meet the requirements of the protective cover to prevent the risk of wound and the explosion risk.
2, look at the small gasoline engine exhaust pipe (muffler), cylinder liner and cylinder head and other parts with high surface temperature whether to set up the protective cover and set a permanent safety warning sign at the obvious place.
3. See if the fuel tank of a small gasoline engine is equipped with a warning sign to prevent fire risk.
Three. Look at the quality of assembly and appearance
1. Look at the material. Check whether the thickness of the sheet covered is consistent, whether the surface is smooth and smooth, or whether the waste material is made. See whether the frame, protective cover and other parts are due to the deformation of the material too thin, the whole machine has no distortion.
2, look at the quality of the paint. Check the paint surface inside and outside the machine is uniform, smooth, consistent color, there are no wrinkles, peeling, flow, lacquer and other defects. Paint the inner surface with a sharp object to check if there is a primer.
3. See the quality of welding. Check the frame and hood part is durable, weld is uniform, there is no leaking welding, weld, wear, sealing off phenomenon.
4. Look at the quality of assembly. Check all parts are complete, easy to scratch parts without flash and burr, installation is firm; the flywheel nut or the power output shaft is to take effective measures in all nuts, rotation and transmission device is flexible rotation, no blockage, loose phenomenon.
Four. Test machine check
1, check the small gasoline engine is easy to start; 2, check the quality of the muffler; 3, check whether the vibration is too large after starting.
Through the above detailed introduction, I believe that you have a good understanding of the purchase of gasoline engine, better purchase.
