Anyone who knows something about the products of drying hot-blast stove knows that the hydraulic system of drying hot-blast stove is mainly composed of oil tank, plunger pump, one-way valve, oil filter, accumulator, nitrogen cylinder, overflow valve, stop valve, hydraulic control one-way valve, oil cylinder, workbench, oil pipeline and valve. Its daily operation means are mainly realized by switching and adjusting the valves in different parts according to the technological requirements. The device that controls the movement of these valves is hydraulic equipment, whose working principle is to transfer power by the pressure energy of liquid oil. And the hydraulic system of drying hot blast stove is a relatively simple one in hydraulic transmission technology. Its working principle and all components are not complicated, and the requirements of production and operation are also the most basic. Therefore, as long as the following four points are paid attention to in use, the basic normal work of the system can be ensured. 一、合理控制系统使用压力
1. Reasonable control system of operating pressure
The operating pressure of the hydraulic system of the drying hot blast stove is determined by the bearing capacity of the hydraulic components, the technological requirements of the small drying hot blast stove and the force required by the transmission valve equipment. Too low or too high can not meet the needs of production process and equipment maintenance, and even cause damage to production and equipment.
2. Use the correct fuel tank
Besides being used for oil storage, the oil tank also has the functions of heat dissipation, heating, clarifying oil and separating air from oil. The effective volume of the tank should be determined by heat dissipation calculation, and there should be enough space to accommodate the amount of oil released from the accumulator when checking the accumulator. The bottom outlet is used to remove dirt from the tank.
3. Correct selection and use of oil
Hydraulic oil is petroleum-based oil. When oil flows, the cohesion between liquid molecules causes internal friction between oil layers and prevents relative sliding between oil layers. This uneven motion of the liquid layer is called salary. If the slaughter is large, the internal friction force will be large, and the oil will be thick, whereas the oil will be thin. And this property varies with temperature. So when choosing hydraulic oil, salary is one of the main bases. In addition, the mechanical impurities, moisture, acidity and alkalinity of hydraulic oil will affect the working performance and equipment life of the hydraulic system. Therefore, in a hydraulic system, the selection of oil must take into account the process, equipment and life. Once the oil is settled, don't change frequently.
In addition, the internal leakage of small drying hot stove is mainly caused by the mechanical wear of hydraulic system executive components and operation and control components, and the wear and aging of internal sealing elements. Among them, the excessive impurities of hydraulic oil and the emulsification caused by the water in the oil are the catalytic factors that cause the leakage of hydraulic components. Therefore, the management of oil is one of the most important tasks for the rational use of hydraulic equipment.
