Causes: 1. The pump is damaged, and the pump body is overheated and produces noise. 2. The control valve is closed tightly or the oil supply and return system is blocked, and local overheating occurs. 3. The safety valve is opened, and the valve cries or hisses, and local overheating occurs. 4. The distribution rotary valve is excessively leaking, and the valve chamber is overheated, and it is very hot when touched by hand. 5. The hydraulic motor crankcase is excessively leaking, and the single oil drain pipe is leaking special-purpose Low speed cycloidal hydraulic motor Treatment method for excessive leakage and high oil level: 1. Check the condition of the ball joint 2. Check the sealing condition of the cylinder piston 3. Check the viscosity and operating temperature of the oil 4. Check the contact surface between the oil pan and the housing 5. Check the surface between the connecting rod and the eccentric wheel Low speed cycloidal hydraulic motor Price 6. Check the wear of the oil pan and whether the two oil cavity channels at the inlet and outlet of the casting are connected
What is the oil supply mode of the hydraulic pump? The straight shaft swashplate plunger pump can be divided into two types: self suction type and pressurized type. Most high-pressure oil supply hydraulic pumps use pneumatic oil tank, and some hydraulic pumps are also equipped with oil make-up slave pump to deliver pressure oil to the oil inlet of the hydraulic pump. The self-priming pump has the characteristics of strong self-priming ability and no need for external oil supply special-purpose Low speed cycloidal hydraulic motor 。 Bearings for hydraulic pumps. The most important part of the plunger pump is the bearing. If the bearing has clearance, the normal clearance of the three pairs of friction pairs inside the hydraulic pump cannot be guaranteed. At the same time, the hydrostatic support oil film thickness of each friction pair will be damaged, thus reducing the service life of the plunger pump bearing. According to the data provided by the manufacturer of the hydraulic pump, the average service life of the bearing is 10000 hours. If the service life exceeds this value, a new port shall be replaced. 3、 Conclusion. The service life of the piston pump is related to the maintenance at ordinary times, the quantity and quality of the hydraulic oil, and the cleanliness of the oil. At the same time, avoid Low speed cycloidal hydraulic motor Price The particles in the oil will wear the friction pair of the plunger pump, which is also an effective method to extend its service life.
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 doy Low speed cycloidal hydraulic motor 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 doy Price Replace. If there is no motor fault, do not disassemble it easily.
In order to meet the needs of national economic development, hydraulic technology will continue to develop rapidly and be widely used in various industrial sectors. Therefore, vigorously developing the hydraulic machinery industry is also special-purpose Low speed cycloidal hydraulic motor In order to revitalize the development of the machinery industry. Based on improving the technical level of basic parts, we will increase the strength of technological innovation, supplemented by policy support, and fundamentally improve the technical level to achieve industrial development. On the other hand, it also shows that the development of hydraulic press in China has entered a new stage, and the development level of heavy equipment represents Low speed cycloidal hydraulic motor Price The engineering technology level of a country. Therefore, in general, the prospect of hydraulic press in China will be better and better.
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 Low speed cycloidal hydraulic motor 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 Low speed cycloidal hydraulic motor 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.
