Hydraulic oil motor An eccentric block is equipped in the oil chamber between the stator and the rotor radial direction, the inner wall of the stator inner side, the guide slot plate is equipped between the stator and the rotor axial two sides, the rotor end face, and the side of the guide slot plate is equipped with a seal cover. hydraulic pressure Oil motor The rotation speed is about 30 rpm, and the flow is small; The oil chamber is generally a fixed section oil chamber, so the torque is large, and it does not need a very large supporting power. In the absence of mechanical transmission, the manual hydraulic oil pump can also be used to drive its operation; It can be widely used in industrial production, agriculture and animal husbandry and daily life. Set a correction value of atmospheric ambient temperature in each time range, correct the command value used to adjust the temperature of hydraulic oil at the hydraulic oil supply source according to the correction value of atmospheric ambient temperature, and implement feedforward compensation for the change of atmospheric ambient temperature in one day as a time period, The operating hydraulic oil can maintain a suitable ambient temperature even under the premise of bearing the transformation of atmospheric ambient temperature and the obvious interference of thermal inertia force.

Characteristics: From the perspective of energy conversion, the hydraulic oil pump and Hydraulic motor It is a reversible hydraulic component, which can output operating fluid to any hydraulic oil pump to change it into the working condition of hydraulic motor; On the contrary, when the main shaft of the hydraulic motor rotates from the external torque, it can also become the working condition of the hydraulic oil pump. Because the two have the same main structural elements - closed and time changeable capacity and corresponding oil distribution mechanism. However, there are still many differences between hydraulic motors and hydraulic oil pumps of the same type because of their different operating preconditions and different functional requirements. Firstly, the hydraulic motor should be capable of forward and reverse rotation, so its internal structure needs to be central symmetric; The rotating speed range of the hydraulic motor should be sufficiently large, especially its extremely low and stable rotating speed. Therefore, it generally adopts rolling bearing or hydrostatic sliding bearing; Secondly, because the hydraulic motor operates on the premise of outputting pressure oil, it does not need to have self-priming working capacity, but the necessary starting torque can be guaranteed only with the corresponding original tightness. Because of this kind of difference, the hydraulic motor and hydraulic oil pump are similar in structure, but can not be reversed.

Classification: According to its structure, hydraulic motors can be divided into gear type, vane type, plunger type and other types. According to the rated rotation speed of hydraulic motor, it can be divided into high speed and low speed. If the rated speed is greater than 500r/min High speed hydraulic motor If the rated speed is less than 500r/min Low speed hydraulic motor 。 The main types of high-speed hydraulic motors are gear type, screw type, vane type and axial plunger type. The main characteristics of the two are high rotation speed, small inertia moment, convenient opening and braking, and high sensitivity of adjustment (speed change and reversing). Generally, the output torque of high-speed hydraulic motor is small, so it is also called high-speed small torque hydraulic motor. The main type of low-speed hydraulic motor is radial plunger type. In addition, there are also low-speed structural types in axial plunger type, vane type and gear type. The main characteristics of low-speed hydraulic motor are large displacement, large volume and low rotation speed (sometimes it can reach a few revolutions per minute or even zero point), so it can be connected to the operating mechanism at any time; Without speed reducer, the transmission mechanism is greatly simplified. Generally, the output torque of low-speed hydraulic motor is relatively large, so it is also called low-speed high torque hydraulic motor.
