Why is the main hydraulic pipe of the baler returning very slowly? Solve!

Jan 07, 2021

   The main hydraulic pipe of the baler returns very slowly. It is very likely that there is a problem with the pilot valve of the reversing valve. The pilot valve may block the port a or port b. The waste paper baler is used to squeeze waste paper and similar products under normal conditions and pack them into a special packaging belt to greatly reduce the volume, thereby reducing transportation volume, saving freight, and increasing benefits for enterprises. The introduction of advanced technology and advanced technology of similar products at home and abroad. Provide you with some basic points of the problem, careful maintenance, if you can't solve it, please call.


   The main hydraulic pipe of the baler returns very slowly. It is very likely that there is a problem with the pilot valve of the reversing valve. The pilot valve may block the port a or port b. The lead frame of the automatic waste paper baler is composed of 4 sets of wire devices installed on a frame. The entire lead frame is suspended on a central axis of the compression frame, and moves horizontally relative to the compression frame under the action of a hydraulic motor. The compression frame is a welded component, and the bottom is equipped with wheels, which can move horizontally along the main slide rail under the push of a hydraulic cylinder. The lifting platform is mainly formed by bolting two horizontal beams, and the lifting platform can move up and down in the vertical direction under the push of two hydraulic cylinders. Provide you with some basic points of the problem, take care of it, if you can't solve it, please call.

1. Due to the slow movement of the oil cylinder, the insufficient flow should be considered. First consider the valve or the oil cylinder bleed. The hydraulic valve may be worn out (a basic type of component failure) or the spool is stuck causing unloading. 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. The oil cylinder should be inspected for damage to the seal. In addition, consider the failure of the regulating mechanism of the flow control valve. Consider whether the oil pump is damaged or sucking in air.

 2. The overflow valve is stuck! If it is not used for a long time, the infected spool (subject to the valve body) is easily stuck. If the oil cylinder has no pressure in a single pass, it will consider the leakage of the oil cylinder and the pump valve The problem is, the specific combination of actual judgment. If you can't perform maintenance and repairs on your own, then call the staff to solve the problem for you, believe in, believe in yourself, believe in our common choice.
