Nai meihengFixWholesale manufacturers of hydraulic cargo elevators have found that the market demand for hydraulic cargo elevators is also increasing. More importantly, some cargo loading and unloading work as well as decoration, hotels, logistics, warehouses, supermarkets, are commonly used in these situations, especially in the decoration industry. I have seen many decoration companies use small hydraulic cargo elevators, which are also specially processed and manufactured, and have some differences from the hydraulic cargo elevators we often see. There are significant differences in structure, shape, lifting speed, and height, and the prices of hydraulic cargo elevators also vary. The hydraulic cargo elevators used in the decoration industry have a low lifting height, some only 2 meters, and do not require many materials. He mainly promotes people, not goods, and rarely promotes goods, so the load is small, but not inferior to the use of other hydraulic cargo elevators. He is stable, safe, interpretable, and durable enough to make hydraulic cargo elevators a good helper in the decoration industry. The function of hydraulic cargo elevators is gradually improving with our needs, and the properties we require are different. Wholesale manufacturers of hydraulic cargo elevators also manufacture according to our requirements.
After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.
Nai meiheng.On the other hand,Nai meihengIndoor hydraulic lifting platform car, under the action of high pressure, the hydraulic system inevitably causes the hydraulic valve to flow back or the sealing components to produce oil. The main reasons for the natural descent of the hydraulic cargo elevator include the following points: replacement of the support valve due to leakage. The lowering valve is damaged or not powered on. Require the lowering valve to be kept clean on a daily basis, and if damaged, replace it with a new hydraulic lowering valve in a timely manner.
The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
.Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Hydraulic lifting table: the hydraulic lifting table is 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 operation heights and can be equipped with various table forms (such as ball, rotary table roller steering, telescoping) tipping, linkage, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, heat dissipation separation of air contained in oil and elimination of foam.
The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years, with the advantages of higher lifting height, stable operation, and simple maintenance compared to the scissor fork type elevator.
Hydraulic cargo elevator: Only when the load of the hydraulic guide rail type lifting cargo elevator cannot start working, should the pressure of the hydraulic system be checked. If the pressure is below the normal range, the set value of the relief valve should be adjusted. Professional elevator manufacturers have high pressure resistance, good waterproof performance, fire and high temperature resistance, strong overload capacity, corrosion resistance, radiation resistance, and long service life

Economic management.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
Remember not to overload, overload is the root cause of many faults.
A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, unless incorrect operation or safety protection devices fail, as the load borne by the steel wire may exceed its breaking capacity. The damage to the steel wire rope of the cargo elevator is mainly gradually formed during long-term use. After a certain period of repeated bending and friction,Nai meihengHydraulic lifting platform frame, the steel wire on the surface of the steel wire rope will experience bending fatigue and wear, and the steel wire on the surface layer will gradually break. At this point, if it cannot be used again, it should be replaced in a timely manner to ensure the safety of the hydraulic platform.
There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
Nai meiheng.The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
