Electric Scissor Aerial Work Platform Solenoid Valve Research

Electric scissor aerial work platform generally uses hydraulic cylinder to lift. The decline solenoid valve is an important part of the entire hydraulic system, which usually installed in the bottom of the hydraulic cylinder. The main function is locking hydraulic cylinder to prevent the platform sinking due to its weight, protect workers safety. This paper first introduces its structure and working principle, and then does the experiments such as resistance pollutants, leakage, and a comprehensive analysis of the decline in the performance of the solenoid valve.
