Preparation work before use of Guizhou reverse osmosis equipment

The reverse osmosis pure water equipment is a high-pressure operation device. For the consideration of reverse osmosis pure water, single-stage reverse osmosis equipment, the equipment itself and the safety of operation, the staff must strictly follow the operating specifications before use, except for this In addition, it is necessary to confirm the switching state of the valve timely and accurately. It is necessary to ensure that the water inlet valve of the filter and the water inlet valve of the high-pressure pump are in an open state, and the high-pressure pump and the RO inlet valve are opened one turn, and the needle valve on the concentrated water pipe is rotated three and a half turns before turning on the produced water and concentrated water. The water outlet valve, after closing the sampling valve and cleaning valve, opens the pressure indicator valve to a half-open state.

When the above conditions are met, it is necessary to turn on the high-pressure pump for trial operation. The PH value of the feed water is within the range of 3-11, one or more of the equipment such as ultrafiltration, integrated pure water equipment, and the reverse osmosis device is automatically closed. Pure water machine water purifier. Row. When the pressure of the equipment's water supply is greater than the osmotic pressure, the filtered water can penetrate the osmotic membrane to achieve a better desalination effect.

In order to ensure the safety of the treated water quality, the reverse osmosis pure water equipment needs to be cleaned regularly or irregularly during long-term use. There are two common cleaning methods for reverse osmosis pure water equipment: 1. On-line cleaning Online cleaning is to clean the entire equipment, Guizhou pure water equipment, and prepare for cleaning and do not need to take out the membrane elements during cleaning. Simple, convenient and fast. However, this method is more suitable for frequent cleaning or cleaning with less pollution. 2 Offline cleaning This method mainly requires the pressure vessel of the reverse osmosis membrane to be taken out of the reverse osmosis membrane element and placed in a dedicated cleaning machine for cleaning. This cleaning method is not complicated to operate and the effect is relatively obvious. It is suitable for situations where the water quality is poor and the online cleaning effect is not ideal.

Construction machinery tires are divided into heavy dump truck tires, loader tires, excavator tires, scraper tires, bulldozer tires, and road roller tires.
