There is a very human relationship now analyzed as 1 pipe is too long. Will make the internal oil of the cylinder can not be completely returned to the tank to participate in the exchange, which will cause the pre-pressed cotton cylinder of the 400 baler, because of its fast moving speed, easy to heat, the oil in the cylinder can not return to the tank to dissipate heat, so that the seal The parts will be in a high-humidity environment for a long time, which will reduce the service life of the seals. In particular, the rubber seals will lose their elasticity and the sealing effect will be worse. In addition, the high-temperature hydraulic oil will also change the viscosity of the oil and reduce the viscosity. It is easy to produce leakage 2 in the severe winter season, out of the box and out of the box and other infrequent movement of the cylinder, due to the influence of low temperature environment, and the oil does not exchange with the hot oil in the thermostat, resulting in too low oil temperature in the cylinder, 1 The viscosity of the liquid is too large, the movement time is prolonged, the production efficiency is prolonged, and the production efficiency is reduced. At the same time, the pressure required is larger than that during normal exercise, and the power is wasted; and in the ultra-low temperature environment, the seals such as the type will crack from the bottom to the lip. Affecting the sealing effect 1 will make the impact of the impurities in the oil and the service life of the hydraulic components caused by the corpse movement wear and tear. It is obvious that controlling the pollution of the hydraulic oil is important. I have a very deep understanding that the air in the oil in the cylinder is difficult to drain the oil in the cylinder. It is mixed with air at the beginning. If it is not exchanged with the oil in the tank, the air will be difficult to drain. The formation of bubbles and some bubbles in the oil creates a cavitation in the oil, so that the original sputum in the tubing of the tubing becomes a discontinuous state. This phenomenon is called cavitation. If the pressure increases, the bubbles are around. The impact plant of the pressurized oil will quickly rupture and condense into a liquid, as this process occurs in an instant. Therefore, in the case of local liquid card impact, the bubbles condense up to 60080 and cause strong noise and oil tube vibration. The air liberated in the pipe wall or other hydraulic component near the bubble condensation area contains oxygen, so that oxygen has Compared with the acidification, the surface of the part is corroded. The corrosion of the part which is produced by the cavitation phenomenon is called cavitation. When we are at the flange of the main cylinder of the baler, we find some small pits. Because of the use of such high temperature caused by cavitation, the bottom and the lip of the 0-type seal will produce scorch or carbonization, which greatly shortens the service life of the seal. There is a small amount of air in the oil, which has no effect on the physical properties of the oil. However, the cavitation occurs at high frequency in the same part for a long time, and the length change of the pipe of the local sputum is lengthened, which will make the impact larger in the hydraulic system. Due to the sudden opening or closing of the valve, causing a sudden change in the speed of movement of the liquid, the kinetic energy of the liquid will be converted into the squeezing energy, causing the pressure of the liquid to change, so that the energy is rapidly converted. Quickly tell the station behind! The liquid, forming a force wave, the speed of the pressure wave transmission 3 is related to the material density of the liquid. If the distance from the valve to the cylinder is the same. Then the time from the valve to the cylinder re-reflecting to the starting point valve is to improve the fine grinding speed of the top roller and reduce the grinding cost. The Xinjiang Agricultural Division processing factory Tan Bing Lizhong leather roller is an important component of the long-staple cotton emulsifier equipment. The quality of the roller repair is good or bad. Directly affecting the quality of the yew, the concentricity of the roller reaches the specified technical standard, so that the leather and the fixed knives can be creased to produce high quality and high yield skin, if the roller Concentricity straightness does not meet the specified technical standards. The gap between the components is difficult to adjust to the specified technical standard range. From the above, we can see that the number of revolutions of the sanding roller is constant, and the linear velocity of the top roller changes when the rotational speed of the roller is changed. When the speed ratio is higher than the speed of the top roller, the sand roller rubs the surface of the roller every second, and the friction is large. The friction resistance is large, the resistance is large, and the grinding depth and grinding are reduced. When the resistance of the cutting 1 is increased, the current of the motor is also large, and the power of the motor should be increased accordingly. The daily work efficiency is 23 skin rollers when the speed ratio of 121 is used. The speed is low, the newly purchased leather roller is only rough-processed, its radial runout is very large, and the straightness of concentricity is very poor. Only the fine grinding can guarantee the straightness of the leather roller, the straightness of the heart degree 1 traditional fine grinding roller It is made of the same speed and fine grinding by the roller and the sanding roller. This method is low in efficiency. In order to improve the grinding speed, our color sanding roller is high, rotating, and the working mode of the roller roller rotates at a low speed. The grinding surface of the second is small. When the grinding depth and the grinding test reach the full load power of the motor, the grinding roller runs, the grinding amount is several times the rotation speed ratio, and the work efficiency is improved from the original 23 to the current 10 In the experimental comparison, the same number of top rollers were finely ground using an improved method. Increased work efficiency, saved 1 ruler, reduced electricity cost (1) and artificial wage sand roller diameter roller roll diameter sand roller speed to kneading roller speed to æ±¾ sand roller line speed rice bran roller line speed rice bran work every day Efficiency At this time, if the valve closing time is called instantaneous closing, then the energy of the flow rate change is all converted into hydraulic energy. This hydraulic shock is called full impact or direct impact, and vice versa. After the indirect rush line is lengthened, if the time for closing or opening the directional control valve is not extended, a full impact may occur, which will increase the impact and cause noise vibration.
After the pipeline is lengthened, there is no doubt that the resistance along the path is large, and he will make the temperature increase easy. One aspect will make the power consumption increase, which is inconvenient, and it is not convenient to adjust the action immediately. Moreover, the oil pump room has abnormal conditions. When the operator is not easy to hear. Inadequate progress solves problems and brings trouble.
To sum up the above points, we recommend that users try to arrange the plant layout according to the foundation provided by us. We have provided the foundations that we have allowed to take into account many factors such as aesthetics and practicality. Try to increase the distance from us as much as possible. We can't follow the foundation construction provided by us. We should contact our technical department 1 in time to discuss the change force 4 so that your baler has no inherent defects. Because the pump room is too far away from the baler to debug the work belt.
