Dear friends: How is the stepless adjustment system for reciprocating machines manufactured by Shanghai Huantian? Could you please give some information on it? Thank you!
To tell you honestly, there are basically no issues with hydrogenation
The quality is unstable; one of the newly installed actuators failed to function during testing； The hydraulic oil pump shafts have broken before. . . ； The failure rate is still much higher compared to Holbig, and there are more sudden problems.
It’s not very useful; it often stops working on its own
Is it a programming issue or a component failure?
There are issues with both the program and the accessories; the load keeps fluctuating randomly between 0 and 100, and the packing of the actuator is leaking severely
The program didn’t pose any issues; after basic debugging, there was not a single malfunction. The main problems were related to the quality of the actuators, and the temperature of the lubricating oil also affected their performance. In winter, when the ambient temperature is low, the oil temperature drops and its viscosity increases, which results in slow loading and unloading or even an inability to load or unload.
What you're referring to is the problems that arise under your local climate conditions: 1. There are issues with the selection of the hydraulic oil grade used in Ring Tian; 2. The design does not take into account protection against freezing and condensation in winter. Right?
1. The lubricating oil is fine; the main issue is that the insulation performance of the lubricating oil tank, which features variable volume control as designed by them, is very poor, especially in winter when it is greatly affected by ambient temperatures； 2. The design did not take into account the effect of ambient temperature on lubricating oil, which indirectly affected the operation of the actuator.
Our company makes use of Huan Tian’s poleless air volume control technology； There were many problems at the beginning, but it improved later on.
