Hydraulic technology working principle and advantages

The hydraulic principle relies on the static pressure of the liquid medium in a certain mechanical and electronic system to complete the accumulation, transmission and amplification of energy, and realize the lightness, scientific and maximization of the mechanical function. Hydraulic principles can be used to build hydraulic drive systems or hydraulic control systems. The basic function of the hydraulic circuit consists in an easily controlled energy transfer in the form of liquid pressure energy.

From the perspective of energy transfer: hydraulic technology is roughly in the middle of mechanical energy transfer and electrical energy transfer. From the aspect of transmission characteristics: mechanical transmission and hydraulic transmission can be said to have fixed characteristics. In contrast, hydraulic transmission and electric transmission are the same, with the characteristics of continuously variable transmission, in addition to constant power, it is easy to achieve constant Features such as speed and constant torque. The characteristics of hydraulic technology can be summarized as follows:
(1)It is easy to carry out stepless speed change, and the shift range is wide, that is, the force and torque can be easily adjusted in a wide range;
(2)The control performance is good, that is, Force, speed, position, etc. can be controlled correctly with high response speed. In addition, it has good adaptability to other control methods such as electrical and mechanical, especially in combination with electrical signal processing, and can obtain excellent response characteristics;
(3)reliable operation and good operating performance;
(4)structure and characteristics It has moderate flexibility;
(5) It can use standard components to form a loop that realizes any complex function. Related books The reason for these characteristics is that the volumetric components are used as the capacity converters, namely the hydraulic pump and the hydraulic actuator, and the lubricated oil (hydraulic oil) is used as the working medium.

Hydraulic system in block making machine

图片
The hydraulic system is a mechanical function that acts through hydraulic pressure. In hydraulic-based systems, mechanical motion is produced by containing pumped liquid, usually produced by moving the piston's cylinder. According to the different forming structures, the block making machine is divided into a hydraulic block making machine and a mechanical block forming machine. Hydraulic machines can produce a variety of bricks by changing different molds. It is mainly designed with hydraulic transmission as a brick, with low noise, large output, etc. It is widely used in buildings, squares, roads, parks and other buildings. As one of Chinese leading manufacturing and export companies, we produce hydraulic concrete block moulding machines that can produce concrete solid blocks, concrete hollow blocks, and interlocking paving blocks. Our product range is the most leading price in the market, especially in Africa and Asia. Our company FULANG is a leading manufacturer and expo

How to maintain block making machine ?What is block machine? Block machine is used for making burning free block,which means block produced can be used directly and need no burning. According to the domestic and international market needs,we need to produce new block machine.The machine has the advantages of compact structure, large pressing force, strong rigidity, full seal and dust control, smooth operation, simple operation, high output value, and long service life.Block machine’s material feeding part and rotary disc part adopts the most advanced technology to achieve large power transmission, stable operation, accurate in place,and low repair rate.So how to maintain hollow block machine ?Let the technical staff to introduce the maintenance. How time flies,when summer is over,winter is not faraway.Winter temperature is relatively low,not conducive to the production and maintenance of general concrete block.Blocks are easily damaged by frozen and the quality is affected.Therefo

Tips and advice for buying a hydraulic brick making machine

图片
If you want to enter the brick or block manufacturing industry, it is an obvious first step from your own hydraulic brick making machine to get your business started. In this guide, we will focus on a few key things to consider when purchasing a hydraulic briquetting press. We will also provide you with some further tips and tricks to track your operations in the industry on the right side. Successful new business itself. With this in mind, let's take a closer look at this topic. First, hydraulic concrete block making machines are available in a variety of sizes, with the largest models costing more than $100,000 and achieving surprising daily production levels. Of course, if you're just getting started in a small business, you probably don't need this productivity at all, in which case you'd better buy a smaller model. Keep in mind that smaller models are usually still able to produce between 50 and 100 blocks per hour, so there is still nothing to sneeze at thi
