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 Crane 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 Zhejiang Price 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.

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 Crane 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 Crane cycloid motor Price 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.

As the power source and actuator of the hydraulic system, the performance of the hydraulic motor has a great impact on the performance of the entire hydraulic system. Therefore, the importance of studying the hydraulic motor performance test system is want to buy Crane cycloid motor It is very important that the rise and application of hydraulic testing technology based on virtual instrument has opened up a broad prospect for the performance testing of hydraulic motors. Hydraulic motors are widely used in machine tools, metallurgy, engineering machinery, plastic machinery, agricultural machinery, mining machinery, marine machinery and many other important fields. The performance of the hydraulic motor has a decisive impact on the whole system, and will directly affect the stability of the system. At the same time, the performance of the hydraulic motor will have an impact on the life of the system components and the production efficiency of the system. Zhejiang Price Unexpected failure of hydraulic motor will greatly reduce production efficiency.

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 Crane cycloid motor Price 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 want to buy Crane cycloid 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 is usually put into operation Zhejiang want to buy Clean before use. The purpose of cleaning is to remove the pollutants, metal chips, fiber compounds and iron cores left in Madai. In the first two hours of operation, even if the motor is not completely damaged, there will be a series of failures. Therefore, the hydraulic motor oil circuit should be cleaned as follows: 1. Clean the oil tank with easy drying cleaning solvent, and then remove the solvent residue with filtered air. 2. Clean all pipes of hydraulic motor. In some cases, it may be necessary to impregnate pipes and joints. 3. Install an oil filter on the pipeline to protect the oil supply pipeline and pressure pipeline of the valve. four want to buy Crane cycloid motor Install a flushing plate on the collector to replace precision valves, such as electro-hydraulic servo valve. 5. Check whether all pipes are of proper size and connected correctly.

During the operation of hydraulic transmission, the hydraulic actuator can be adjusted steplessly in a large range by adjusting the control valve, and the speed range can reach 2000 meters. Good operation ability and rapidity. The liquid is elastic and can absorb impact, so the hydraulic transmission movement is even and stable; It is easy to realize fast starting, braking and frequent reversing. Reciprocating rotation want to buy Crane cycloid motor The reversing frequency of rotary motion can reach 500 times/minute, and the reciprocating linear motion can reach 1000 times/minute. It is easy to control operation and realize overload protection. The hydraulic system with convenient operation and control is convenient for automatic control, remote control and overload protection; Automatic lubrication during operation, which is beneficial to Zhejiang Price Heat dissipation, prolong service life. It is convenient for automation and electromechanical hydraulic integration. Hydraulic technology is easy to combine with electric control and electric control technology to form an electromechanical hydraulic integration composite system to realize automatic cycle work.
