As a hydraulic equipment, hydraulic motor has been widely used in many factories. Generally, we should master the assembly skills of the hydraulic motor: the hydraulic system should want to buy Danfoss cycloid motor Correct machining and assembly. The mounting surface of the hydraulic valve on the oil block should be straight, and the sealing surface of the sealing groove should be finished to avoid radial scratches. The preload of the connection between the hydraulic valve and the oil circuit block and the connection between the oil circuit blocks shall be sufficient to prevent surface separation. The hydraulic equipment shall be inspected according to relevant standards before assembly Danfoss cycloid motor manufactor Check the pressure leakage of system components. If problems are found, corresponding measures shall be taken. If the problem is serious, it should be replaced. Accurately formulate the assembly process documents of hydraulic equipment, configure necessary assembly tools, and strictly follow the assembly process. Keep the hydraulic components, accessories, sealing parts and pipe fittings clean to prevent contamination, and check the integrity of the sealing surface and connecting threads. The hydraulic connector should not be tightened too tightly, otherwise some parts will be severely deformed or even broken, causing leakage. Avoid damaging sealing parts during assembly.
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.
The manufacturer of the hydraulic motor has explained to us the relevant knowledge about the speed and low-speed stability of the hydraulic motor. The speed of the hydraulic motor depends on the flow of the supply fluid q and the discharge of the hydraulic motor itself v. The hydraulic motor has internal leakage. Not all the liquid entering the motor drives the hydraulic motor to work. Some of the liquid is lost due to leakage, and the actual speed of the motor is lower than the ideal situation. When the working speed of the hydraulic motor is too low, it cannot maintain a uniform speed, and it stops when entering Xuchang Danfoss cycloid motor The unstable state is a creeping phenomenon. The high-speed hydraulic motor is required to work at a speed below 10r/min and the low-speed high torque hydraulic motor is required to work at a speed below 3r/min. All hydraulic motors can meet the requirements. Generally speaking, the low-speed stability of low-speed large torque hydraulic motors is better than that of high-speed motors. Due to the large emissions and size of the low-speed high torque motor, the sliding speed of the friction pair will not be too low even if the rotation speed is low want to buy Danfoss cycloid motor Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.
Its basic types are gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, adjustment (speed adjustment and want to buy Danfoss cycloid motor Reversing) High sensitivity. As the output torque of high-speed hydraulic motor is generally small, it is also called high-speed small torque hydraulic motor. Its basic type is radial plunger type, in addition, there are axial plunger, vane type, gear type and other structural types. Low speed hydraulic motors are mainly characterized by large displacement, large volume and low speed (sometimes Danfoss cycloid motor manufactor It can rotate a few revolutions per minute or even a few revolutions per minute), so it can be directly connected to the working mechanism; It does not need a speed reducer, greatly simplifying the transmission mechanism. Usually, the output torque of low-speed hydraulic motor is large, so it is also called low-speed high torque hydraulic motor.
At present, in the hydraulic system of construction machinery, the commonly used oil change method is by cycle or by train number. The hydraulic system of some construction machinery requires that the hydraulic oil be replaced when the motorcycle is 1200. surface want to buy Danfoss cycloid motor Grid 6 has reference value. For the maintenance of the hydraulic system, the parameters in Table 7 of the used hydraulic oil can better explain the problem. If the three items in Table 7 generally exceed the limit, the hydraulic oil shall be replaced. Except that the solid particles exceed the limit, that is, the hydraulic oil shall be replaced if the solid particles exceed the limit. During field inspection of oil, empirical inspection shall be carried out first, and whether to continue quantitative inspection shall be determined according to the observed oil pollution. According to the test results, determine the solution Danfoss cycloid motor manufactor What measures shall be taken for oil pressure (half oil change, full oil change or filtration). Thus, the quality of hydraulic oil in the hydraulic system can be guaranteed, so as to reduce system failures and improve the reliability of the system.
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. want to buy Danfoss cycloid 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 Xuchang 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.
