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 OM cycloidal 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 Hangzhou OM cycloidal 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.
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 OM cycloidal motor Manufacturer 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 OM cycloidal 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.
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 OM cycloidal 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 Hangzhou Manufacturer 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.
Generally, rolling bearing or hydrostatic sliding bearing, hydraulic customized OM cycloidal motor 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 Hangzhou OM cycloidal motor High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.
