Full-automatic concrete mixer truck is one of the necessary mechanical equipment in modern construction engineering. Do you know what will happen if its oil number and tank design are unreasonable? Let's explain it to you.
(1) Improper selection of the oil number of the hydraulic oil may cause the heating of the hydraulic system. When the oil temperature is low, the system works normally. However, after the system works for a period of time, the oil temperature increases and the viscosity of the hydraulic oil decreases, resulting in an increase in the internal leakage of the system. With the increase of the leakage, the oil temperature increases, forming a vicious cycle of oil temperature. The solution is to select the hydraulic oil with proper viscosity according to the load of the system and the requirements of normal working temperature.
(2) The design of the oil tank is unreasonable, which reduces the heat dissipation effect of the hydraulic system. The main function of the oil tank is to store hydraulic oil, but it also has the functions of heat dissipation, precipitation of impurities, and water separation. The design of fuel tank is unreasonable, mainly in two aspects:
First, the volume of the oil tank is too small. Because the fully automatic concrete mixer is a mobile hydraulic equipment, the volume of the oil tank is generally about twice the flow of the hydraulic mixer, so the heat dissipation area and oil storage capacity of the oil tank are small;
Second, some oil tanks are not reasonably designed in structure. The oil suction and return nozzles are relatively close, and there is no partition in the middle, which shortens the cooling cycle of oil in the tank and the path of settling impurities, and even causes most of the return oil to directly enter the oil suction pipe, reducing the heat dissipation effect of the oil tank and increasing the oil temperature.
The solution is to properly increase the volume of the oil tank, and try to increase the distance between the oil suction pipe orifice and the oil return pipe orifice, and set a partition between the oil suction and return pipes to ensure the heat dissipation power of the oil tank.
What will happen if the oil number and tank design of the mixer truck are unreasonable? The above is the relevant answer to the question. I hope to help you. Please come to our website for more matters consulting service
