Division I should be looking for the required product quality assurance lifts

forklift jacks as mechatronics special equipment, widely used in various residential, commercial services and facilities, railways, airports and other buildings, and its development is closely related with the process of urbanization. China is the world's largest elevator manufacturing, selling and exporting countries, after years of competition with foreign brands, national brands have made great progress overall capacity. Benefit from the protection of housing construction and urbanization deepened.
Pump output flow or no flow output. Pump output flow shortage for many reasons, which requires itemized overhaul.
(1) insufficient intake. The reason is that the flow of suction piping resistance is too large or fill fuel shortage. If pump rotation. Tank level is too low, the oil temperature over hoop, into the pipeline leak, oil filter blockage.
(2) excessive leakage. The reason is that the gap is too large, resulting in poor scissor pallet truck. As with the oil pan by metal fragments, iron and other scratches, face oil greatly increased. Variables institutions sealing surface with the bad check valve, pump and bearing surface with the oil pan with blisters or cracks, etc. This can be checked in the pump body foreign matter mixed in the hydraulic oil, does not determine the site of the pump being damaged. Troubleshooting should be based on various reasons. If the check valve sealing surface re-spotting, grinding oil pan and cylinder face, replacement parts have blisters or cracks. When the plunger and the plunger bore badly worn or damaged, it should be re-bore plating, grinding and other processing repairs. If badly worn piston variable displacement mechanism, replaceable piston, the piston and the piston bore clearance is 0.02 mm. When the oil pan is not placed between the pump body and cause a large leak, you should open the pump reassembly. If oil viscosity is too low, so that each part increased leakage, to replace the hydraulic oil.
Lift developments are in a peak state, because most manufacturers or individuals in order to improve the utilization of space, more options multistory building, which also requires a device to facilitate the drop down to enhance cargo. As ordinary elevator high cost, low capacity, not suitable for loading tens or hundreds of tons of tons of goods, so the development of a high-capacity hydraulic lift to assist the production and transport of goods. Hydraulic cargo lift that is safe and has a large load capacity, and easy maintenance, making this particular industry and some faster development.
