Hydraulic lifting column as some of the main places of maintenance equipment, more and more loved by everyone. What are the factors that lead to the instability of the hydraulic lifting column? The following is a good answer for everyone.
1. The hydraulic pipeline is also very important. The hydraulic pump is also an important factor affecting the flow of hydraulic oil. The hydraulic pump that has been used for too long is also prone to problems. When the speed of the electro-hydraulic lifting column slows down, check the hydraulic pump oil supply flow Whether it is stable;
2. The electric hydraulic lifting column often has phenomena such as difficult to detect the rising position, impact noise when rising, and oil leakage of hydraulic cylinder. The main reason is that the lifting speed of the lifting hydraulic cylinder is too fast, resulting in an increase in failure rate and serious Affect production efficiency. There are three applications for lifting columns-construction, security and landscaping. All bollards can have architectural and landscaping common, only in style, shape and material differences. When it comes to safety applications, different bollards are used to block different objects. Hydraulic lift instability is the first to analyze the factors of hydraulic oil flow, hydraulic oil quality is not good, there are a lot of impurities, will also lead to slow blockage;
3. Establish a speed rigidity analysis for the lifting circuit. The flow rate into the hydraulic cylinder, that is, the flow rate through the one-way throttle valve, is the flow rate through the throttle valve, the throttle shape of the throttle valve and the viscosity of the hydraulic oil. The greater the speed rigidity of the throttle speed control circuit, the better the speed stability of the hydraulic circuit.
4. The diameter of the cylinder and the flow rate of the hydraulic oil. The speed of the hydraulic lift is inversely proportional to the cross-sectional area of the cylinder piston rod, and is proportional to the hydraulic oil flow. The diameter of the cylinder is fixed. When the speed of the hydraulic lift is slow, priority should be given to the hydraulic flow;
