Construction site special wheel washer advantage one, fully automatic, ultra-accurate all-round high-pressure cleaning Henan Inalvit mechanical wheel washing machine adopts automatic computer control system, easy to achieve unattended, can greatly reduce the cost of manual cleaning, the starting control system of the machine adopts Japan imported photoelectric sensor, extremely high precision, long service life

　　Wheel washers make air pollution no longer become the biggest hidden danger to our health, and the relevant reports say that the biggest health and safety problem of our human beings comes from air pollution, I believe that hearing such reports, the fear of air pollution in each of our hearts has increased by another point. We thought the pollution was serious enough

　Engineering wheel washer is specially designed for the washing of various large engineering vehicles on the construction site, the equipment can automatically complete the work of flushing and sludge discharge. Rinse water can be recycled and only a small amount of water needs to be replenished during operation, so a lot of water can be saved. It is especially suitable for dense residential areas, all kinds of construction sites, cement plants, coal mines, landfills, concrete plants and other factories. The equipment is easy to install and transport, and can adapt to the needs of frequent transfer of construction sites. Engineering wheel washer manufacturers analyze the negative impact of construction vehicle pollution on the surrounding environment, mainly including: 1. The impact of damage to the surface 　　

　Easier and optimized foundation pit structure design of engineering wheel washer: engineering wheel washer is cost-effective, and the simpler and optimized foundation pit structure design makes the production cost and later maintenance cost lower, the product volume is smaller, more convenient to transport, and more cost-effective; Environmental protection and energy saving: innovative use of advanced treatment technology combining sewage automatic circulation purification system and screw conveying sludge discharge system to more effectively save water, electricity and other energy, reflecting the concept of green environmental protection 　　

　　How to carry out daily maintenance of engineering wheel washing machine equipment? Engineering wheel washer equipment is a new type of site cleaning environmental protection equipment that should be required by environmental protection policies, but also one of the points to be inspected by various environmental protection departments, the wide range of engineering wheel washers is undoubtedly to a large extent to solve the problem of road pollution of construction site vehicles, engineering vehicles working in the construction site only need to go through the engineering wheel washer equipment for a few minutes to clean on the road, so that the road pollution situation is effectively solved, so engineering wheel washing machine equipment is currently each construction site should be equipped with environmental protection equipment.

　Construction project wheel washer, site wheel washer flushing water is equipped with a special pool, designed as a clear water pool and sedimentation tank to ensure the recycling of water. The construction site wheel washer adopts the method of sludge removal pump to remove the sludge: usually the method of removing the silt of the car wash by the construction site wheel washer equipment is to use the scraper to scrape out the sludge, and this method cannot scrape the sludge at all in actual use

　Construction site wheel washer is a set of automatic washing facilities, environmental protection, energy saving, recycling of water resources are its characteristics, can clean all kinds of construction site vehicles, so that the construction site vehicles meet the requirements of the road. Today, the editor of Hunan Ruisheng Mechanical and Electrical Equipment briefly talks about the working principle of the entire cleaning system of the engineering wheel washer: 　　

　Do you know what a construction site wheel washer does? With the country's increased efforts to protect the environment, it has increased rectification efforts for various industries with pollution, especially the construction site industry. In order to prevent some vehicles entering and exiting the construction site from causing environmental pollution, the construction site needs to install a site wheel washer at the entrance. Some customers may have questions in their minds, that is, does this construction site wheel washer have to be installed? The editor of the construction site can clearly tell the majority of construction site contracting customers and friends: the construction site wheel washer must be installed. The wheel washer is looking for our Hunan Ruisheng mechanical and electrical equipment, and now follow the editor to see why the construction site wheel washer must be installed. 　　

What is the maintenance method of screw air compressor oil and gas separator filter element? Maintenance should be carried out after the air compressor is stopped and the corresponding safety measures are made. Small air compressors mostly use rotary oil and gas separator filter elements, and their maintenance methods are the same as oil filters; The built-in step is as follows: loosen the piping on the oil and gas barrel while maintaining the pressure valve (minimum pressure valve)

Screw air compressor working principle and several common small problems, now follow Hunan Ruisheng mechanical and electrical equipment Xiaobian to see, Zhigao screw air compressor working principle, compressed air system using twin screw air compressor. The work of the machine is divided into three processes: intake, compression and exhaust:
