Reasons for oil leakage of output shaft of omp 50 hydraulic motor


How much do you know about omp 50 hydraulic motor? If you don't know much, after reading this article, I believe you will have a general understanding of it.

omp 50 hydraulic motor is a kind of cycloid motor. The cycloid motor is a small, low-speed, high-torque hydraulic motor of internal meshing cycloid gear type. Its structure is simple, low-speed performance is good, and the short-term overload capacity is strong. The cycloid motor has a stator and a movable blade. The stator, the blade and the drive shaft divide the motor into two chambers, each chamber has an oil port, when an oil port When the oil is in, the other one is out, and the propelling blade of the incoming oil swings. The omp 50 hydraulic motor perfectly continues the advantages of the cycloid motor. It adopts an integral stator and rotor pair, with precise structure, novel appearance, free reversal of forward and reverse rotation, adjustable speed range, and stable operation. High efficiency, large torque and low noise, can be used in parallel and series. Used in construction machinery, agricultural machinery, transportation, machine manufacturing and other departments, such as conveyors, operating machines, injection molding machines, harvesters, tubing clamps, manipulators, cranes and other mechanical equipment. This is a very good product. However, some users have encountered the problem of oil leakage from the motor output shaft. Even if the seal of the output shaft is replaced, it will not help. What is the reason for this? The answer is that the user ignores the issue of case drain pressure when choosing a tandem application.

The case drain pressure refers to the maximum pressure that the motor shaft seal can withstand after the motor is fully lubricated; if the motor is not used properly, after the machine has been working continuously for a period of time, the oil in the case will not be released due to various factors. Released, as a result, the motor's case pressure will become higher and higher, causing the shaft seal to fail in the first place. The case drain pressure mentioned here is not the case

The burst pressure is the pressure that the dynamic seal of the motor output shaft can withstand. Some manufacturers' motor samples only mention back pressure. In fact, back pressure refers to the return pressure of the motor, not the case drain pressure.

Here, I recommend a company, Hanjiu Technology, as a professional manufacturer of hydraulic products, Hanjiu Technology has more than ten years of experience in the production of hydraulic products, and its products are exported to all over the world and are widely praised. Process and continuous research and development efforts, so the omp 50 hydraulic motor it produces has better pressure-bearing capacity of the dynamic seal of its output shaft, that is, the company's products have a unique internal oil channel design, so that the internal oil leakage can not only play a role The function of lubricating parts can also drain excess oil while maintaining a certain housing drain pressure. Hanjiu Technology has always been committed to producing high-quality products. The drain pressure of the motor casing is also related to the motor speed, which is explained in detail in the product catalog of Hanjiu.

But it is not that the lower the case drain pressure, the better. The case drain pressure should be kept at a reasonable level so that the motor can operate normally. What range should the case drain pressure be kept in? This question will be discussed with you in the next article.
