The rise and decline of the hydraulic lifting platform depends on the expansion of the hydraulic cylinder, but how does the components of the lifting platform cooperate with the work? The following brief explanation:
(1) When the pressure of hydraulic lifting system is too high：
The hydraulic circuit of the shear lift is: fuel tank -filter -hydraulic pump -overflow valve -fuel tank
(2) When the system pressure does not exceed the rated pressure of the hydraulic pump：
To achieve the process of lifting the lifting platform, its hydraulic circuit is: fuel tank -filter -hydraulic pump -one -way valve -the left position of the three -way four -pass electromagnetic replacement valve -one -way valve -hydraulic cylinder -hydraulic cylinder —— Three -level four -way electromagnetic transformation valve -fuel tank -fuel tank
To achieve the decline of the scissor lifting platform, its hydraulic circuit is: fuel tank -filter -hydraulic pump -one -way valve -one -way valve -the right position of the three -way electromagnetic transformation valve -hydraulic cylinder- Balance valve -speed regulating valve -the right position of the three -bit four -bon electromagnetic transformation valve -fuel tank
To make the lifting platform in a static state, its hydraulic circuit is: fuel tank -filter -hydraulic pump -one -way valve -the median of the three -way four -pass electromagnetic replacement valve -fuel tank
