Precautions for Disassembling the Hydraulic Pump of a Scrap Metal Baler In our daily use of scrap metal balers, it is imperative to avoid disassembling the hydraulic pump. The oil used in the hydraulic system of scrap metal balers has very low compressibility, and its impact can generally be ignored under normal circumstances. Therefore, even if the system contains a small amount of air, it can significantly affect the performance of the scrap metal baler.Air dissolved in the oil will escape from the oil at low pressures, causing gas saturation and cavitation phenomena; when these bubbles reach high-pressure areas, they are quickly shattered by the pressure of the oil, rapidly compressed, generating noise in the system, and when the gas is suddenly compressed, it releases a large amount of heat, causing local overheating and damaging hydraulic components and oil.The high compressibility of air also causes the actuating elements to creep, disrupting operational smoothness, and sometimes even causing vibrations, all of which affect the normal operation of the scrap metal baler system. Depending on the different reasons for air entering the system, the following points should be noted during use and maintenance:An exhaust valve should be installed at the top of the oil cylinder of the scrap metal baler to facilitate the removal of air from the cylinder and system. Scrap metal balers accommodate larger variations in oil temperature and load than those using throttle valves. The parallel hydraulic cylinder synchronization circuit using flow control valves is simple in structure, low in cost, and thus widely applied.Efforts should be made to ensure that any pressure within the scrap metal baler system is always below atmospheric pressure, while using particularly good sealing devices, replacing failed ones promptly, tightening pipe connections and joints with screws, and cleaning the oil filter at the entrance of the scrap metal baler's oil tank regularly.Regularly check the oil level in the scrap metal baler's tank during daily operations, ensuring it remains above the oil gauge line. At lower levels, the oil suction port and return oil port must also be below the liquid surface, separated by a baffle. In case of an emergency, stop work immediately.To understand the composition and structure of scrap metal balers, consider these aspects:

Scrap metal balers are mechatronic products, primarily composed of mechanical systems, control systems, feeding systems, and power systems. The entire baling process consists of pressing, returning, lifting the box, rotating the box, ejecting the package upwards, ejecting the package downwards, and receiving the package among other auxiliary times.On the market, waste paper balers are mainly divided into horizontal and vertical types. Vertical waste paper balers are smaller in size because they have smaller baling dimensions and are less efficient.In contrast, horizontal waste paper balers are larger in volume but have greater compression force than vertical balers, larger baling dimensions, higher efficiency in packaging output, and are easier to automate, as most waste paper balers adopt a horizontal form.Horizontal waste paper balers are easy to automate, can improve overall baling efficiency, and save on labor costs for baling.The wire guide frame of a vertical waste paper baler consists of four sets of wire guide devices installed on a frame, suspended on a central axis of the compaction frame, moving horizontally relative to the compaction frame under the action of a hydraulic motor. The compaction frame is a welded component with wheels at the bottom, capable of horizontal movement along the main slide rail under the push of a hydraulic cylinder.The lifting platform is mainly formed by two horizontal beams bolted together, which can move vertically up and down under the push of two hydraulic cylinders.

The main rail seat of a vertical waste paper baler is mainly composed of two wear-resistant steel tracks set on the surface. The wheels of the compaction frame are guided to run along the outer sides of the two tracks, with the hydraulic cylinders that drive the compaction frame arranged in between. Besides mechanical components, there is also a complete set of hydraulic stations. From the above description, it can be seen that various movements of scrap metal balers are completed by the power of fluids.Characteristics of scrap metal balers include high compression ratios, strong processing capabilities, durability, and suitability for baling different shapes and sizes of metal materials.
