How to choose your snow removal machine-rolling brush articles_faq

With the development of society and the advancement of science and technology, people’s quality of life is gradually improving, and the requirements for urban transportation, environment and their own living conditions are getting higher and higher. City managers are also constantly improving their management level, striving to meet people’s needs, food, shelter, transportation , Try to create a comfortable environment for everyone. Clearing snow in cities in winter is an important part of sanitation work, and sanitation workers in various places are increasingly aware of the importance of snow clearing work. Today, with mechanized snow removal operations as the main method, the selection of snow removal equipment in the early stage is very important. It can be said that the quality of snow removal equipment will directly affect the effect of later snow removal operations. Below, we will start from a professional point of view and give suggestions for purchasing various snow removal equipment for the reference of users. 1. Snow sweeping brush The function of the snow sweeping brush is to rotate the same part of the ground multiple times within a unit time by rotating at a high speed, so as to separate the snow from the road surface and sweep the snow to the right side of the road. It can show its advantages when the road area is not thick with snow, the cleaning effect is good, the cleanliness rate is high, and it can achieve the effect of seeing the road. The disadvantage is that it cannot cope with thicker compacted snow and icy roads. When choosing to use the snow removal roller brush for snow cleaning, we need to pay attention to the following aspects of the snow removal roller brush: 1. Hydraulic system: The hydraulic system is the core part of the snow removal roller brush work, which provides power for the roller brush. The hydraulic system consists of hydraulic pumps, hydraulic motors, hydraulic valve blocks, hydraulic oil tanks, radiators and hydraulic oil. Among them, hydraulic pumps, motors and valve blocks are the top priority of the hydraulic system. Key words of hydraulic pump: pump type pump displacement working pressure There are two types of hydraulic pumps in the snow removal rolling brush hydraulic system on the market. One is that the flow rate and pressure output are variable, which can be changed with the load (the snow removal rolling brush works on the ground) The variable variable pump, the other is a constant flow and pressure output, and does not change with the load. The two types of hydraulic pumps have a huge difference in the effect of roller brush snow removal, service life, and product stability. The advantage of the variable pump over the fixed pump is that the snow removal energy is 'supplied on demand'. The roller brush provides different energy requirements under different working conditions, with low energy loss and low system heating, thereby prolonging the service life of the equipment hydraulic system components. On the contrary, If you choose a fixed pump output, no matter what working conditions the roller brush encounters, the system always works at 100% energy output, which causes a lot of energy loss and the hydraulic oil heats up quickly. This is why some users use the snow removal vehicle to work for a while After time, the equipment had to be stopped for 'cooling downThe displacement of a pump is a manifestation of the 'capacity' of the pump. It refers to the hydraulic oil removed by the impeller of the pump after one revolution. The displacement is multiplied by the number of revolutions of the pump per minute to obtain the flow rate of the pump. The greater the displacement of the pump, the greater the flow provided to the hydraulic system, the stronger the power of the hydraulic system and the higher the speed of the roller brush. On the contrary, the smaller the displacement, the power of the hydraulic system will be insufficient. But the flow rate provided by the pump is related to the number of revolutions per minute of the pump. Generally, the engine speed is controlled at about 1500 rpm when the snow removal vehicle is working. If the speed is too small, the pump provides too little flow. Work under load, the loss of the chassis vehicle is relatively large. At present, in order to reduce production costs, some manufacturers use small displacement hydraulic pumps, but in order to maintain the effect of rolling brushes, they can only 'small horse-drawn carts'. Each time snow removal, the snow removal vehicle must step on the accelerator pedal to the end, which affects the chassis. The vehicle loss is quite large, so buyers must pay attention to the displacement of the pump, and choose a standard speed to measure the pump capacity. The pressure of the pump is an important point to pay attention to when purchasing. There are three pressure values u200bu200bin one of the hydraulic pump parameters: continuous pressure, intermittent pressure, and peak value. Continuous pressure refers to the pressure at which the hydraulic pump can operate for a long time, that is, the working pressure of the hydraulic pump. When working within this pressure range, the performance of the pump can be maintained within the normal range; the intermittent pressure is higher than the continuous pressure, which is Refers to the short-term and intermittent working pressure of the hydraulic pump in a specific environment (such as the sudden lifting of the snow removal brush, sudden encounter with thick snow, sudden encounter with large obstacles, etc.). The hydraulic pump can only achieve this in a short time. The pressure value, then restored to the continuous pressure range, can not work at this pressure value for a long time, the peak value is the largest pressure value of the three pressure values, generally refers to the maximum test pressure of the hydraulic pump, and it is not allowed in actual working conditions There is a peak condition. According to our company's years of experience in the production of snow removal equipment, the working pressure of the hydraulic system during work is generally about 60-70% of the working pressure of the hydraulic pump, so that the hydraulic system is well protected while ensuring the effect of roller brushing. Therefore, when inquiring about the pump pressure energy, be sure to ask the seller whether the pump pressure parameter provided by the seller is continuous working pressure or discontinuous pressure.
