Principle Principle of electric elevator: hydraulic oil is formed by a vane pump to a certain pressure, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve to make the piston of the hydraulic cylinder Move upwards to lift the weight. The oil return from the upper end of the cylinder is returned to the fuel tank through the flameproof electromagnetic reversing valve. The rated pressure is adjusted through the overflow valve, and the pressure gauge reading value is observed through the pressure gauge. The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil at the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and the brakes are safe and reliable, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve adjusts the flow rate and controls the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulic control check valve, namely hydraulic lock, is added to ensure that the hydraulic pipeline can be safely self-locked when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure. The electronic control system can control the rotation of the motor through the explosion-proof button to change the direction of the explosion-proof electromagnetic directional valve to keep the load rising or falling, and adjust the time delay through the “LOGO” program to avoid frequent starting of the motor. Inflexible lifting, jam phenomenon. With the development of social science and technology, electric elevators have been popularized in all corners of social life and used more and more widely. Whether it is construction, civil engineering, or people’s daily life, electric elevators are inseparable from many businesses. This business opportunity has invested in the establishment of factories, and electric lift machinery companies have been established like bamboo shoots in major industrial cities. The electric lift market is extremely hot and demand exceeds supply. It can be seen from the side that the rapid development of society has led to the development of the entire industry. People’s needs, however, as a buyer, how to choose a good electric lifting machine among the company’s products has become an important topic today. 1. When purchasing electric lifting machinery, you should not buy it blindly. It is necessary to do sufficient market research and field inspection to determine the company’s scale and its credibility. This is first and foremost. Many small-scale companies in the market cut corners in order to seek violence, thereby greatly reducing the quality of lifting products. Although they will sell very cheaply, this kind of machinery does not take long and has a high risk factor. . Therefore, as a purchaser, you cannot covet a little price and cause greater regret. 2. Based on the information you have investigated, choose an electric lifting machine with a good price/performance ratio. You must choose from its technical parameters, practicability and versatility. Usually there are many kinds of electric lifting machines, including (vehicle type, fixed type, (Hydraulic, Scissor, etc.) Each has slightly different technical parameters and uses, but there are also many similarities in functions. Therefore, as a customer, you have to purchase with a purpose, that is, if you buy a lift mechanical What to do, and what kind of lifting machinery can meet your needs and has many uses. 3. The last point is that after the equipment arrives, when unpacking and accepting, check whether the random technical data is complete, whether the random accessories, tools, and accessories are consistent with the list, whether the equipment and accessories are damaged, defective, etc., and do the unpacking acceptance recording.
