Troubleshooting and Maintenance of Foaming Machines Hydraulic Station Pressure Fluctuations The hydraulic station in a foaming machine shows the driving force for the introduction of the mixing nozzles. Since the amount of mixing head introduced is closely related to the opening and closing time of the cylinder, the hydraulic station must be high and stable enough. When the hydraulic station fails to deliver pressure, the performance of the foaming machine will decline significantly. Next, I will teach you how to solve this problem.
The filter in the suction port of the hydraulic oil pump is too dirty, if the pump cannot suck oil, not only the vapour pressure will rise, but also the damage of the pump will be aggravated, so please clean the filter element carefully. The low increase in working pressure is associated with damage to the pump and speed control valve. Gear oil pumps used today can easily cause damage to their own structure and must be replaced frequently. Speed control valves are easily fatigued by long-term use, so please adjust them promptly to avoid working pressure leaks.
Our working pressure often varies a lot, this is because the skin pack in the energy storage device is damaged, we can replace the skin pack. In addition, the slide valve of the switching valve will flow downward and the working pressure of the hydraulic station may change. The application of polyurethane foam is well cleaned and maintained, and if it is not handled properly during use, it will immediately affect the use, while the service life of the product will be greatly shortened. Even for durable machinery and equipment, good cleaning and maintenance can further improve the service life of machinery and equipment.
Many people do not pay attention to the cleaning and maintenance of the equipment when they first start using it, but after two or three years of use, they will find that it will be easy to break down if they do not go to clean and maintain the equipment when they first use it, so it is important to do a good job of cleaning and maintenance.
Polyurethane foaming machine must be well moistened, in some important parts position to do a good job of moistening work, often maintenance of polyurethane foaming machine. The selection of lubricant is also very important, can not use some excessively cheap lubricant, because the cheap lubricant is very easy to block the problem.
