Piston cylinder abnormal sound reasons are the following: the piston and cylinder wall with the gap is too large, and therefore acting in an instant, the piston will be subject to the pressure of high pressure gas in the cylinder so as to produce sound swing; piston pin and bushing or connecting rod bearing and journal with tight; oil too early, and so on. In the face of such a situation, how to do it? To make the engine of choice for stable state Knocking loudest, followed by each cylinder stop working, according to changes in each cylinder to stop the sound judgment, which is the most simple of a solution. After judging the source of the problem, to solve the problem for good. Detection shed body: Before installing greenhouses rolling machine, we must first conduct a detailed understanding of vegetable greenhouses, greenhouses require sufficient strength and bearing capacity; something greenhouses at a height requirement of symmetry, but low-lying before the shed to avoid installation and adjustment difficulties; Note roof leaked at the mouth of the film not to suppress leaked, leaked difficult. Selection models: the weight shed length, width, height and thatch curtain, greenhouses rolling machine reference manual to determine the choice of rolling machine model, taking into account the rain, snow, the weather will increase the weight of thatch curtains, greenhouse arch , width. Determine the electric rolling machine Model greenhouses shutter machine manufacturer, be sure to leave the load margin. For safe use of greenhouses rolling machine, to prevent accidents, the company recommends that customers focus on the following issues: 1. The first-time users before rolling machine shed needs please read its instructions. 2. Before use, greenhouses rolling machine body to inject oil 4 kg, later to be replaced once a year. 3. During the installation or use, should regularly check the host and all screws are loose connections, broken welds whether open welding and other problems. 4. Before using the brake clutch system must be oiled to maintain lubrication greenhouses rolling machine specifications, in order to avoid premature wear greenhouses rolling machine for sale, resulting in brake failure. 5. roll up to the rolling machine shed roof 30 cm, must be shut down. In case of brake failure dashing into the inverted switch down (reverse) direction, so rolling machine down properly after maintenance.
