Concrete mixer starts difficult to find the cause is the key
It is hard to believe that many of my friends have been baffled by the start-up of vehicles. At the same time, they will find it very bothersome. Mixers should have this kind of situation. What should we do? Let's find the symptoms first, and then apply the medicine. The factors that cause the concrete mixer to start difficult are probably summed up the following points, are still in troubled card friends, may wish to check and check
1. When starting the concrete mixer truck, if only the sound from the electromagnetic switch of the starter is heard, the crankshaft does not rotate, which may be caused by the battery “breakingâ€. It is recommended to check the battery.
2. The self-discharge of the concrete mixer battery is serious, and the aging of the plates and separators will also cause short-term parking to start, but it will be more difficult to start again after a long period of parking. It is recommended to consider replacing the battery.
3, starter found that the starter suddenly turning powerless, accompanied by a burning rubber smell or smoke at the battery, then it may be extremely poor pile and pole clamp contact, resulting in heat burned.
4. When the starter starts, the drive gear and the flywheel ring gear of the engine flywheel will make an impact sound, which may be caused by the deformation of the meshing cut-in surface of the flywheel ring gear of the concrete mixer wheel.
5. When the main power switch is turned on, the drive gear of the concrete mixer starter meshes with the flywheel ring gear. This may be because the starter solenoid switch's holding coil is wrongly connected to the power terminal or the key switch. The three lines on the wrong connection.
6. If there is only a slight "click" at start-up and there is no response afterwards, there may be a problem with starting the relay to issue a card.
