1. Electromagnetic power main switch can be directly installed next to the battery of JLl065.1075 harvester, select a qualified orientation control switch on the instrument panel (in the normal operation, any part of the body will not accidentally touch the position, In case of abnormal operation of the main power switch, only one wire can be connected to the main switch. The line should be consistent with the direction of the lower wiring harness of the bridge. When the wall of the car is over the line, it should be far away from the moving parts and properly handle the contact part with the car wall to prevent the short circuit caused by friction. In many years of practical work, we have found that the current electromagnetic power main switch also has many shortcomings: (1) The continuous current supply is needed during work. Once the control circuit is open circuit, the whole vehicle voltage will rise and cause damage to the power equipment. . (2) If you forget to turn off the main switch while parking, it will cause loss of battery power. (3) It can only be controlled in the car, causing inconvenience to the maintenance work under the car. After repeated trials, we chose the Russian-made power switch (model FOCT3940-84) to solve the above problems. The Russian-made power switch uses an electromagnetic-mechanical double-acting switch, which is controlled by a push button installed in the car. It can also be manually controlled by the car. No current passes through the control circuit during operation, and forgetting to close the switch will not cause damage. Battery energy consumption. In practice it works well. 2. In order to solve the starter's "follow-up" phenomenon, we added a starter working indicator to the instrument panel. When the starter is powered on, the indicator light is on. When the starter switch is released, the light goes out. Just one indicator light and one wire (most of the harvester's granary under the granary plug has a white blank line, can use this line directly), one end of the wire is connected to the indicator, and the other end is connected to the starter magnetic switch. Small posts. The starter is powered by the start switch - starter relay - magnetic switch to start the electrical operation, and any part of it can not be well disconnected, will make the starter engine rotation at high speed after the engine is running, and this indicator only It can be extinguished when all the above electrical switches are off, so its working reliability is very high. If the driver finds that the indicator light is not extinguished after starting the engine, the engine should be shut down in time, disconnect the power switch and wait until the problem is identified, and then restart. This will enable the expensive starter to be protected from damage and will be used for several years. Proven effect is very good. 3. Almost all modern car lighting systems are equipped with light relays, because there is no light relay installed on the JLl065.1075 harvester, which reduces the efficiency of lights, and the frequent line temperature rise accelerates the aging of the wire harness, greatly shortening the In order to solve this problem, we have installed two small relays (model JD2912) behind the headlights to solve this problem. This allows the lighting system to flow through the ignition. The current of the switch is very small, which not only greatly prolongs the service life of the switch, but also reduces the temperature rise of the circuit, and at the same time, the brightness of the light is significantly improved.
The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
