use High pressure cleaner Cleaning the railway tank car can achieve the purpose of water saving, steam saving and pollution reduction. However, in winter in northern areas, freezing and condensation of the cleaning machine pipeline is likely to occur, which affects normal use. By improving the anti-freezing and condensation of the high-pressure cleaning machine, good results have been achieved. The anti-freezing effect ensures the normal use of the high-pressure cleaner in winter.
The cleaning of railway tank cars before oil loading is an important measure to ensure the quality of oil products. The cleaning of railway tank cars is divided into general washing and special washing. According to the relevant quality requirements, the general washing only needs to remove the residual night, clean and wipe without impurities. Yes, special car washing requires steaming and water washing. The special washing process that has been used in the past is: pumping residual liquid, manual descaling, blowing replacement, steam heating for 45-60 minutes, manual cleaning agent scrubbing, fresh water flushing, sewage pumping, blowing drying, using this car washing process Mode, car wash time is long, consumption of steam, water, cleaning agent, etc. are large, which causes certain pollution to the environment, the labor intensity of employees is high, and the work efficiency is low. The use of high-pressure cleaners to clean railway tank cars can save 2,000 tons of steam by saving 0.7 tons of steam per car and washing 3,000 cars per year. In terms of water saving, each car can save about 0.9 tons of water and nearly 3,000 tons of water per year. At the same time, car washing with chemicals is no longer used, which can reduce the consumption of cleaning agents, bamboo root brushes, mops and brooms. The special washing time is greatly reduced. 1~2 hours, achieve the purpose of improving the efficiency of brushing, reducing consumption, reducing labor intensity, and reducing environmental pollution.
Although there are many advantages to using a high pressure washer, in the northern area, the weather is cold in winter, the outlet pipe of the high pressure washer is a dn10 high pressure hose with a small diameter and a length of about 22 m. If there is water in the pipe or pump, it is easy Frozen hoses or plunger pumps not only cause losses, but also affect the normal operation of the car wash. The problem is very prominent. On the other hand, when the water temperature is low in winter, it will also affect the cleaning effect. Therefore, in order to use high-pressure cleaners in northern regions, it is very important to solve the problem of anti-freeze condensation.
