The balance circuit of the one-way sequence valve is adopted for the weight drop of the waste paper baler

Jan 04, 2021

       The hydraulic cylinder of the vertical waste paper baler or the vertically moving working parts cause the working chamber to form a vacuum because of its own weight falling or the speed in the downward movement exceeds the speed that the hydraulic pump can reach, which is out of control or stall, the waste paper baler Standing balance circuit. The balance circuit is to set an appropriate resistance on the downward return oil path of the vertical hydraulic cylinder, so that the back pressure generated by it can be balanced with its own weight. The following describes the work flow of the balance circuit of the one-way sequence valve of the waste paper baler.


       The hydraulic cylinder of the vertical waste paper baler or the vertically moving working parts cause the working chamber to form a vacuum because of its own weight falling or the speed in the downward movement exceeds the speed that the hydraulic pump can reach, which is out of control or stall, the waste paper baler Standing balance circuit. The automatic waste paper baler is a mechatronic product, mainly composed of mechanical systems, control systems, feeding systems and power systems. The whole packing process consists of auxiliary time such as pressing, returning, carrying, transferring, outgoing up, outgoing down, and receiving. The balance circuit is to set an appropriate resistance on the downward return oil path of the vertical hydraulic cylinder, so that the back pressure generated by it can be balanced with its own weight. The following describes the work flow of the balance circuit of the one-way sequence valve of the waste paper baler.

Here, the adjustment pressure of the balance circuit sequence valve of the waste paper baler using the one-way sequence valve should be slightly greater than the pressure formed by the weight of the working parts in the lower cavity of the hydraulic cylinder. Mineral water bottle packing machine This product has the characteristics of good rigidity, toughness and stability, beautiful appearance, convenient operation and maintenance, safety and energy saving, and low investment cost of equipment basic engineering. It is widely used in all kinds of waste paper factories, waste recycling companies and other units and enterprises. It is suitable for the packaging and recycling of waste paper, plastic straw, etc. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower, and reduce transportation costs. With the increasing awareness of environmental protection, waste paper balers have played a great role. Some waste paper can be reused, and it is becoming more and more accepted by everyone. Domestic waste paper balers have been In constant innovation, we are constantly following the development of some foreign advanced technologies. When the reversing valve is in the neutral position, logically, the piston can stay in position, but due to the leakage of the sequence valve, the piston will actually fall slowly. When the pressure oil enters the upper cavity of the hydraulic cylinder of the waste paper baler to push the piston down, the sequence valve opens when the back pressure is greater than the set pressure of the sequence valve, and the piston and moving parts descend. The weight is balanced, so There is no speed phenomenon. When the reversing valve works in the right position, the pressure oil enters the lower cavity of the hydraulic cylinder through the one-way valve, the upper cavity of the cylinder returns oil, and the piston and working parts move upward. This kind of circuit adopts M-type functional reversing valve, which can make the upper and lower cavities of the cylinder be closed when the hydraulic cylinder stops working, which can lock the working parts. In addition, it can unload the pump and reduce energy consumption. This kind of circuit can make the movement of the waste paper baler relatively stable, but the power loss on the sequence valve is large when the piston moves down, so it is used for the waste paper baler system with the same weight of the working parts and not too large , Such as in the hydraulic system of vertical modular machine tools, slotting machines, and forging machine tools.
