The hydraulic motor is usually put into operation Hebei special-purpose Clean before use. The purpose of cleaning is to remove the pollutants, metal chips, fiber compounds and iron cores left in Madai. In the first two hours of operation, even if the motor is not completely damaged, there will be a series of failures. Therefore, the hydraulic motor oil circuit should be cleaned as follows: 1. Clean the oil tank with easy drying cleaning solvent, and then remove the solvent residue with filtered air. 2. Clean all pipes of hydraulic motor. In some cases, it may be necessary to impregnate pipes and joints. 3. Install an oil filter on the pipeline to protect the oil supply pipeline and pressure pipeline of the valve. four special-purpose Cycloidal hydraulic motor of sanitation vehicle Install a flushing plate on the collector to replace precision valves, such as electro-hydraulic servo valve. 5. Check whether all pipes are of proper size and connected correctly.
Generally, rolling bearing or hydrostatic sliding bearing, hydraulic special-purpose Cycloidal hydraulic motor of sanitation vehicle Since the pressure motor works under the condition of input pressure oil, it does not need to have self-priming capacity, but it needs to have a certain initial air tightness to provide the necessary starting torque. The existence of these differences makes the structure of the hydraulic motor and the hydraulic pump relatively close, but they cannot work reversibly. The classification of hydraulic motors can be divided into gear type, impeller type, plunger type and other types according to the structure type. According to the rated speed of the hydraulic motor, it can be divided into high speed and low speed. The rated speed exceeds 500r/min Hebei Cycloidal hydraulic motor of sanitation vehicle High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.
If the hydraulic system is compared to the human body, then the hydraulic oil is equal to human blood. In the hydraulic system, the hydraulic oil plays a role in energy transmission, system lubrication, and prevention Hebei Cycloidal hydraulic motor of sanitation vehicle The functions of corrosion, rust prevention and cooling, and whether the hydraulic system can work effectively are closely related to the type and selection of hydraulic oil. Coding, composition and characteristics of hydraulic system: high purity general machine tool oil, refined mineral lubricating oil, with good rust resistance and oxidation resistance. High wear resistant hydraulic oil, refined mineral lubricating oil, rust proof, anti-oxidation, anti-wear. High temperature and high pressure hydraulic oil, with the characteristics of rust prevention, oxidation resistance, wear resistance, etc., is refined into mining lubricating oil, and added with viscosifier. Refined mining lubricating oil HG hydraulic guide oil, rust proof, anti-oxidation, anti-wear, anti stick slip. HS synthesis special-purpose Cycloidal hydraulic motor of sanitation vehicle Hydrocarbon is a kind of low temperature hydraulic oil, which has the characteristics of anti-oxidation and anti-wear.
Precautions during operation of cycloidal hydraulic motor: before operation, check whether all parts of the hydraulic system are connected correctly, and inject oil into the specified Hebei Cycloidal hydraulic motor of sanitation vehicle Height. Start and run without load for 10-15 minutes, and exhaust. Air bubbles in the oil tank, noise in the system, and gas accumulation in the engine oil cylinder all prove that there is air in the system. After the gas is discharged, fill the oil tank, and then gradually increase the load of the motor until the load is too large. Observe whether there is noise, oil rise, oil leakage and other abnormal phenomena. After 50 hours of operation, change the oil according to the maintenance rules, and then the oil according to the maintenance rules Hebei Price Replace. If there is no motor fault, do not disassemble it easily.
Hydraulic transmission system, the hydraulic transmission system is generally an open loop system without feedback, which mainly transmits power, supplemented by information, and pursues the perfection of transmission characteristics. Hydraulic elements special-purpose Cycloidal hydraulic motor of sanitation vehicle The characteristics of components and their interactions determine the working characteristics of the system, and its working quality is greatly affected by the changes of working conditions. Hydraulic drive system is widely used. The hydraulic system of most industrial equipment belongs to this category. In the hydraulic control system, servo valves and other electrohydraulic devices are mostly used in the hydraulic control system Cycloidal hydraulic motor of sanitation vehicle Price The control valve constitutes a closed-loop system with feedback, which mainly transmits information, supplemented by power, and pursues the perfection of control performance. The system adds detection feedback, which can combine common components into an accurate control system, and its control quality is less affected by the change of working conditions. Hydraulic control system is widely used in high-precision CNC machine tools, metallurgy, aerospace and other industries.
1. Generally, the motor shall be able to run forward and backward. Therefore, the hydraulic motor is usually required to have structural symmetry in the design. 2. The actual working pressure difference of the hydraulic motor depends on the load torque. When the moment of inertia of the driven load is large and the speed is high, rapid braking or reverse rotation is required, high hydraulic impact will be generated. Therefore, the system should be equipped with necessary safety valves and buffer valves. 3. Under normal working conditions, the inlet and outlet pressure of the hydraulic motor is higher than the atmospheric pressure, so there is no suction performance problem like the hydraulic pump. However, if the hydraulic motor can work under pump conditions, its oil inlet should have a minimum pressure limit to avoid cavitation. 4. Some hydraulic motors must have sufficient back pressure at the oil return port to ensure normal operation. The higher the speed, the greater the back pressure, which indicates that the utilization rate of oil source pressure is not high and the system loss is increased. 5. Because the internal leakage of the motor is inevitable, there will be slow sliding when the hydraulic motor oil outlet is closed for braking. Therefore, when long-term accurate braking is required, a separate anti-skid brake shall be set.
