The device that can be converted into rotary motion is called motor. The hydraulic motor is a device that can convert the pressure energy of liquid medium into rotary motion. It converts the hydraulic energy provided by the hydraulic pump into mechanical energy. At the same power output, the weight and size of the hydraulic motor is only 5% - 20% of that of the DC motor, and the relative weight is very light, so the moment of inertia is small, the starting, braking and reversing are fast, the low speed stability is good, and the inorganic speed regulation can be easily realized. how special-purpose Cycloidal hydraulic motor of sanitation vehicle Select the hydraulic motor suitable for yourself: the main parameters of the hydraulic motor include pressure, flow, displacement and output power; The choice of the ideal hydraulic motor mainly depends on your desired power and Yangzhou Manufacturer The hydraulic pump you are using now matches. You can also see the selection of displacement. The displacement V is obtained by dividing the system flow Q by the required motor speed n. Select the model according to the displacement and check the prototype to see whether the motor torque meets the requirements.
1. Pascal principle: also known as static pressure transmission principle, it refers to the pressure exerted on the static liquid in a closed container is transmitted to all points of the liquid at the same time with equal value. The hyperbolic cosine of 2. The hyperbolic cosine of 2. System pressure: the discharge pressure of the hydraulic pump in the system. The hyperbolic cosine of 3. The hyperbolic cosine of 3. Servo valve and proportional valve: infinitely adjust the output of hydraulic valve, such as pressure, flow and direction, by adjusting the input electrical signal analog quantity. (Servo valve also has pulse special-purpose Cycloidal hydraulic motor of sanitation vehicle Wide modulation input mode). But the structure of these two valves is completely different. The servo valve controls the work of the torque motor by adjusting the electrical signal to deflect the armature and drive the front valve to work. The front valve control oil enters the main valve and drives the valve core to work. The proportional valve regulates the electrical signal to make the electric iron shift, drive the pilot valve core, drive the control oil generated, and drive the main valve core. The hyperbolic cosine of 4. The hyperbolic cosine of. Yangzhou Cycloidal hydraulic motor of sanitation vehicle Kinematic viscosity: the ratio of dynamic viscosity μ to the liquid density α. The hyperbolic cosine of 5. The hyperbolic cosine of 5. Fluid power: the force exerted by the flowing liquid on the solid wall to change the flow velocity.
The hydraulic motor has two circuits: the hydraulic motor series circuit and the hydraulic motor braking circuit. These two circuits can be classified into the next category. One of the series circuits of hydraulic motors: three hydraulic motors are connected in series with each other, and a reversing valve is used to control the start stop and steering. The flow through the three motors is basically the same. When the displacement is the same, the speed of each motor is basically the same. The oil supply pressure of the hydraulic pump Yangzhou Manufacturer High, small pump flow, generally used for light load and high speed. Serial circuit II of hydraulic motor: each reversing valve in this circuit controls one motor, each motor can work independently or simultaneously, and the rotation direction of each motor is also special-purpose Cycloidal hydraulic motor of sanitation vehicle optional. The oil supply pressure of the hydraulic pump is the sum of the working pressure difference of each motor, which is applicable to the condition of high speed and small torque.
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 Cycloidal hydraulic motor of sanitation vehicle 。 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 Cycloidal hydraulic motor of sanitation vehicle Manufacturer 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.
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 Cycloidal hydraulic motor of sanitation vehicle Manufacturer , 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 Yangzhou Cycloidal hydraulic motor of sanitation vehicle 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.
