What is a hydraulic system?


2020-10-16

The role of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil. Hydraulic systems can be divided into two categories: hydraulic drive systems and hydraulic control systems. The main function of hydraulic transmission system is to transmit power and movement. The hydraulic control system must make the output of the hydraulic system meet specific performance requirements (especially dynamic performance).

Why are hydraulic lifting platforms so popular?


2020-10-16

The hydraulic lifting platform mainly realizes the function of lifting through the pressure transmission of hydraulic oil. Its shear fork mechanical structure enables the lifting platform to have higher stability, and the large working platform and higher load-bearing capacity make it possible to work at heights. The scope is larger and suitable for multiple people to work at the same time. It makes high-altitude operations more efficient and safer. The working principle of hydraulic lifting platform The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the cylinder through the oil filter, explosion-proof electromagnetic reversing valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the cylinder moves upwards and lifts the weight. The oil return from the upper end of the hydraulic cylinder is returned to the fuel tank through the flameproof electromagnetic reversing valve, and its rated pressure is adjusted through the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge. (Recommended   Precautions for the safe use of the lifting platform) The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the cylinder returns to the 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 hydraulically controlled one-way valve, that is, hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure. use The hydraulic lifting platform is widely used in various industrial enterprises and production lines such as automobiles, containers, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different working heights, and can be equipped with various table tops (such as balls, rollers, Turntable, steering, tilting, telescopic), with various control methods (split, linkage, explosion-proof), has the characteristics of stable and accurate lifting, frequent starting, large load capacity, etc., effectively solving the difficulties of various lifting operations in industrial enterprises, making Production operations are effortless.

Influencing factors of hydraulic cylinder sealing


2020-10-13

Factors affecting the sealing of hydraulic cylinders   Today's hydraulic cylinders are used by many manufacturers, but many people do not understand this. If the seal is not good, it will completely affect the normal use. The current sealing is mainly affected by the following factors: 1, talk about hydraulic cylinder sealing, first, the current production process requirements. Because if the manufacturer has no position in the production process, it will directly affect the seal. Because if the production process is not high, it will directly lead to insufficient sealing of the butt joint and easy to produce gaps. 2. In addition, when producing hydraulic cylinders, which production materials are mainly used. Because if the production material used is a relatively smooth and high-quality material, it will not affect the sealing of the accessories. Therefore, many companies now need to understand the sealability of the company during use or purchase in order to better use it. The above are the factors that affect the tightness, which can play a certain role in many companies. It is inseparable from the tightness of ensuring the normal operation of the equipment. I hope this product knowledge can help you operate the equipment better.
