& nbsp; The goods lifting platform is a type of lifting equipment composed of walking organization, hydraulic organization, electric control organization, and supporting organization. Hydraulic oil is composed of a vane pump to generate a certain pressure. It enters the lower end of the hydraulic cylinder through an oil filter, a explosion-proof electromagnetic directional valve, a throttle valve, a hydraulic control check valve, and a balance valve, causing the piston of the hydraulic cylinder to move upward and lift the heavy object. The return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and the additional pressure is adjusted through an overflow valve. The pressure gauge is used to investigate the reading value of the pressure gauge.
& nbsp; Troubleshooting method for goods lifting platform: 1. Overload solution: reduce load, unclosed return valve solution: tighten the return valve, manual pump check valve stuck, return failure solution: unscrew the oil pump valve bolt, inspect, clean, and replace clean hydraulic oil. 4. Severe oil leakage solution for manual pump and gear pump: replace the oil pump seal ring.
& nbsp; The gear pump is damaged and the oil produced has no pressure. Solution: Replace the gear pump. Solution: Insufficient hydraulic oil. Solution: Add enough hydraulic oil. Solution: Check the button contactor and fuse. Filter blockage solution: Replace or clean, support valve or electromagnetic reversing valve malfunction solution: Repair or replace A. The input voltage of the electromagnetic coil is lacking 220V
