With the development trend of technological progress in today's society, the application of aluminum alloy elevators is becoming increasingly widespread. Whether it is engineering construction, architecture, or people's daily lives, hydraulic press lifting machinery is indispensable. Many shop owners seize this entrepreneurial opportunity and compete to invest and establish factories. With the emergence of rising stars in major industrial production cities after being heartbroken, the lifting machinery manufacturing industry is still popular and in high demand. From the side, it can be seen that the rapid development of the social economy is driving the development trend of all manufacturing industries and the demands of everyone. However, as consumers, how to choose good lifting machinery from many enterprise products has become a key topic of discussion nowadays.
1： When purchasing lifting machinery, one should not blindly follow the trend. Adequate market research and visits should be conducted to clarify the business scale and reputation level of the enterprise. It is essential and necessary. Nowadays, many small-scale taxpayers in the sales market sell inferior products as high-quality ones in order to gain explosive power, which greatly reduces the quality and quantity of elevator products. Although they may sell them at a good price, this type of mechanical equipment does not take long and has a high risk index. Therefore, as consumers, we cannot create greater shortcomings just by seeking a lower price.
2： Based on the materials you have researched comprehensively, when selecting a cost-effective lifting machinery, you need to choose from its performance parameters, applicability, and practicality. Generally, there are many types of aluminum alloy profiles (melting point 660 ℃) lifting machinery, including (b ā o ku ò) (mobile lifting platform, fixed lifting platform, electric lifting platform, scissor lift, etc.), each with slightly different performance parameters and main uses, but there are also many areas with similar functions. Therefore, as a consumer, you can make targeted purchases, that is, what you want to do with the lifting machinery, and which lifting machinery can consider your needs and main uses. The sentence is:.
3： The final point is that after the delivery of the machinery and equipment, when unpacking and verifying, it is necessary to check whether any technical documents are complete, whether any spare parts, special tools, and notes are consistent with the details, whether the machinery and spare parts are damaged, defective, etc., and to keep a good record of the unpacking project acceptance.
The principle of the aluminum alloy profile (melting point 660 ℃) lifting platform:
Hydraulic oil is generated by an axial piston pump to generate a certain working pressure. It enters the lower part of the hydraulic cylinder through an oil filter, an explosion-proof electromagnetic directional valve, an overflow valve, a hydraulic control check valve, and a static balance valve, causing the piston rod of the hydraulic cylinder to move upwards and lift heavy objects. The return oil above the hydraulic cylinder returns to the car oil tank through an explosion-proof electromagnetic directional valve. Its rated working pressure is adjusted according to the speed control valve, and the reading value of the pressure gauge is observed based on the pressure gauge.
The piston rod of the hydraulic cylinder moves downwards for fitness (i.e. lowering heavy objects). The gear oil enters the upper part of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil below the hydraulic cylinder returns to the car fuel tank through the static balance valve, hydraulic control check valve, overflow valve, and explosion-proof electromagnetic directional valve. To stabilize the lowering of heavy objects, the braking system can be trusted by setting a static balance valve on the return oil passage to balance the control circuit and maintain the working pressure, so that the lowering rate will not be changed by the heavy object. The total flow rate is adjusted by the overflow valve to operate the elevator speed. To ensure the reliability of the braking system and prevent accidents, the hydraulic control check valve, also known as the hydraulic press lock, is raised to ensure safe locking in case of unexpected hydraulic pipeline rupture. Install an overweight voice control alarm system to distinguish between overweight or mechanical failures.
