As far as energy conversion is concerned, the hydraulic pump and hydraulic motor are connected as reversible hydraulic components, and the working fluid can be input into any kind of hydraulic pump to make it become a hydraulic motor; On the contrary, when the main shaft of the hydraulic motor rotates under the action of external force Sweeper cycloidal hydraulic motor manufactor It can also become a hydraulic pump. Because they all have the same basic structural elements, namely sealed and recyclable volume and corresponding distribution mechanism. However, the working environment of hydraulic motor and hydraulic pump is different customized Sweeper cycloidal hydraulic motor The performance requirements are also different. Therefore, there are many differences between the hydraulic motor and the hydraulic pump of the same model. The first hydraulic motor should be positive and negative, so its internal structure should be symmetrical; The speed range of the motor must be large enough, especially its minimum stable speed must have certain requirements.
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 Huzhou manufactor 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 customized Sweeper cycloidal hydraulic motor 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.
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 customized Sweeper cycloidal hydraulic motor 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 Huzhou manufactor 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.
Functions: It is used for the storage, supply and recovery of hydraulic media, the connection between hydraulic components and the transmission of energy carrying hydraulic media, filtering impurities in the hydraulic media, keeping the media required for the normal operation of the system clean, heating or cooling the system, storing and releasing hydraulic energy or absorbing hydraulic pulsation and impact, and displaying the pressure and oil temperature of the system; Hydraulic working medium: various hydraulic oils (fluids), efficacy: as the energy carrying medium of the system, it plays the role of lubrication and cooling while transferring energy. Generally speaking, the hydraulic components that can complete certain specific functions are called hydraulic circuits. In order to meet the working requirements of certain machinery or equipment, the overall structure of several special basic functional circuits connected or combined together is called hydraulic system.
Actuator: hydraulic cylinder, hydraulic motor and swing hydraulic motor. Function: convert the pressure energy of liquid into mechanical energy, which is used to drive the working mechanism to do work and realize reciprocating straight customized Sweeper cycloidal hydraulic motor Linear motion, continuous rotation or swing; Governor: pressure, flow, direction control valve and other control elements. Function: control the oil pressure, flow and direction from the pump to the actuator in the hydraulic system, so as to control the force (torque) and speed output by the actuator Huzhou Sweeper cycloidal hydraulic motor Degree (speed) and direction, to ensure that the main engine working mechanism driven by the actuator can complete the predetermined motion law; Hydraulic auxiliary device: oil tank, pipe fittings, filter, heat exchanger, accumulator, indicating instrument, etc.
When the working load changes from low speed to high speed in a wide range, the hydraulic motor is also required to be able to drive and regulate speed in the corresponding wide range, which requires the motor to have good low-speed stability and high speed performance. The speed regulation range K of the hydraulic motor is usually expressed by the ratio of the allowable maximum speed to the minimum speed. customized Sweeper cycloidal hydraulic motor It is the highest operating speed of hydraulic motor, but it is limited by many factors, mainly including: 1. Service life. After the speed increases, each pair is worn Huzhou manufactor The service life is shortened. 2、 Mechanical efficiency limits. At high speed, the hydraulic motor needs to input large flow, accordingly, the hydraulic loss of each circulating component increases, reducing the mechanical efficiency.
