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 high torque 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 high torque 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.
During the operation of hydraulic transmission, the hydraulic actuator can be adjusted steplessly in a large range by adjusting the control valve, and the speed range can reach 2000 meters. Good operation ability and rapidity. The liquid is elastic and can absorb impact, so the hydraulic transmission movement is even and stable; It is easy to realize fast starting, braking and frequent reversing. Reciprocating rotation special-purpose Low speed high torque cycloidal hydraulic motor The reversing frequency of rotary motion can reach 500 times/minute, and the reciprocating linear motion can reach 1000 times/minute. It is easy to control operation and realize overload protection. The hydraulic system with convenient operation and control is convenient for automatic control, remote control and overload protection; Automatic lubrication during operation, which is beneficial to Beijing Price Heat dissipation, prolong service life. It is convenient for automation and electromechanical hydraulic integration. Hydraulic technology is easy to combine with electric control and electric control technology to form an electromechanical hydraulic integration composite system to realize automatic cycle work.
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 Beijing Low speed high torque 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 Beijing Price Replace. If there is no motor fault, do not disassemble it easily.
When the main reversing valve of the central closing system and the central closing system is in the neutral position, all oil ports of the reversing valve are closed. If a fixed pump is used for oil supply, the liquid of the hydraulic pump will return to the tank at high pressure through the overflow valve. When the reversing valve is in neutral position, energy transmission starts from the high value, that is, the maximum pressure regulating value of the system. Just reverse Low speed high torque cycloidal hydraulic motor Price , its energy can be used by the actuator. When the reversing valve is in the middle position, it sometimes bears all the pressure of the system, so the internal leakage is greater than that of the open system. Generally, when the Beijing Low speed high torque cycloidal hydraulic motor In this case, the energy consumption of the closed loop is high, but if the intermediate unloading measures are added or the pressure compensated variable pump is used for oil supply, the energy consumption of the closed loop can be greatly reduced. Closed hydraulic systems are used for a variety of equipment.
