Characteristics and working principle of hydraulic elevator Overview The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric control mechanism and a supporting mechanism. The hydraulic oil is formed with a certain pressure by the vane pump, and enters the lower end of the liquid cylinder through the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the liquid cylinder moves upward to lift the weight The return oil at the upper end of the liquid cylinder returns to the tank through the explosion-proof electromagnetic directional valve. Its rated pressure is adjusted by the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge. 1. Principle Hydraulic lifting platform products are divided into crank arm hydraulic lifts, scissor hydraulic lifts, mast hydraulic lifts, and straight arm hydraulic lifts according to working methods. Hydraulic lift is a replacement product of folding arm lift (lifting platform) and scissor lift (lifting platform). It can be widely used in the decoration, decoration of the facades of the stations, terminals, airports, hotels, post and telecommunications, municipal gardens, grain depots, cleaning companies, public buildings or the installation and maintenance of power systems, etc. The elevator has the advantages of light weight, self-propelled, electric start, self-supporting legs, simple operation, large working surface, especially capable of working at heights across obstacles. 1. The hydraulic lifting platform can be divided into: four-wheel mobile type, two-wheel traction type, car modification type, battery car type, auxiliary self-propelled type, and lifting height ranging from 4 meters to 18 meters. The load of this series of products is divided into 0.1 to 0.8 tons, which can also be customized according to user requirements. The maximum load can reach 10 tons. 2. The hydraulic lifting platform is widely used in the maintenance of industrial and mining enterprises' workshops, municipal construction, decoration of hotels and hotels, with reliable quality and perfect performance. 3. The user can choose the power mode and configuration according to his use range: ①The power system includes: battery DC power supply, single-phase or three-phase power supply, diesel engine. ②Walking: auxiliary self-propelled, two-wheel traction, self-driving, and car modification. ③ Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand outriggers, pull-out outriggers. ④Control system: explosion-proof electric control system, remote control system, PIC control system, ⑤Hydraulic pump station: pump station for domestic lifting platform, imported pump station from Italy ⑥Outside is the protection device: organ cover type, mesh type, iron plate sealed type. 3. Purpose Hydraulic lifts are widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different operating heights, and can be equipped with various tabletop forms (such as balls, rollers, turntables) , Steering, tipping, telescopic), with various control methods (split, linkage, explosion-proof), it has the characteristics of stable and accurate lifting, frequent starting, and large load, etc., which effectively solves the difficulties of various lifting operations in industrial enterprises and makes production Homework is easy. The hydraulic lifting platform mainly realizes the lifting function through the pressure transmission of hydraulic oil. Its scissor mechanical structure makes the lift have higher stability, a wide working platform and a higher carrying capacity, so that the working range at high altitude Larger and suitable for multiple people working at the same time. It makes the aerial work more efficient and more secure.
