Waterjet cutting machine maintenance matters, how to do waterjet maintenance in winter?
The water jet is a star commodity in the cutting machinery. It has a wide range of uses. After buying the water jet cutter, it needs to be maintained. When winter comes, the water jet needs to be maintained, let's talk about how to maintain it. In November, the northern hemisphere enters winter, and the temperature of users in high latitude areas is also close to 0 degrees Celsius, and the waterjet maintenance must also be converted to winter mode. The low temperature in winter has a great impact on many operations. As the equipment with water as the main medium, water jet is not small, but production is still necessary, so how to do a good job of water jet in cold winter What about maintenance? I believe that many users who newly purchase water jets have no experience in this regard. Share some of this experience with you today. Here are some tips for water jet maintenance:
This mainly involves two aspects of maintenance: one is the oil pump, and the other is to prevent the water from freezing
We all know that the power of the water jet comes from the oil pump, and the oil pump has strict requirements on the viscosity of the hydraulic oil. In general, water jets should use anti-wear oil in winter. However, after the water jet is turned on, it is basically necessary to contact the work, and the temperature rises quickly. Therefore, Xiaobian's suggestion is to use anti-wear hydraulic oil in winter. When starting the machine cold, firstly operate at low pressure (only turn on the oil pump, do not turn on the high pressure) for 5~10 minutes, and then carry out the cutting process after the operating noise of the oil pump is normal.
The water jet is powered by the water-sand mixture mixed with the water jet sand at high speed to achieve the purpose of cutting, and the water will freeze when it is below zero, so the biggest problem of water jet operation in winter is freezing. So how can we minimize the impact of temperature on water jets?
It is recommended that you take the following steps to keep the water jet cutting machine warm:
1. Put on a "cotton jacket" for the pump;
2. "Bake" the machine before starting the cold machine every day until there are water droplets at the end of the high-pressure pipe;
3. At the end of processing every day, remove the cutting head and store it against freezing;
4. Turn off the water supply of the water pump, and start the oil pump to empty the water in the high-pressure cylinder, accumulator and high-pressure pipeline as much as possible;
5. The machine needs to be preheated in advance before starting the machine every day, and do not use it directly.
The winter maintenance of the water jet is introduced. Obviously, even a product as good as a waterjet cutter needs to be well maintained when winter comes, so have you learned how to maintain a waterjet in winter?
