Everyone knows the function of the pressure reducing valve when using a hydraulic baler,but how to solve the problem if the pressure reducing valve fails?
1.The hydraulic baler inlet and outlet of the pressure reducing valve are opposite,please pay attention when using it.The mark near the oil port on the valve,or refer to the product catalog of hydraulic parts,do not design errors or connect errors.
2.The inlet pressure is too low.After the orifice of the pressure reducing valve core,the output pressure of the outlet will decrease.
3.The load on the downstream circuit of the pressure reducing valve of the baler is too small to build pressure. At this time,please consider connecting a throttle valve downstream of the pressure reducing valve to solve this problem.
4.Due to the accumulation of dirt,the contact between the pilot valve and the valve seat mating surface is poor and cannot be closed;or the pilot cone is severely scratched,the valve seat matching hole is not round,and there is a gap, resulting in the pilot valve core and valve seat hole tight.
5.In the process of disassembly and maintenance,the missing poppet valve will not install the poppet valve in the valve seat hole.In this regard,the assembly or tightness of the taper can be checked.
6.The hydraulic baler orifice on the main spool is blocked by dirt,and the oil cannot flow into the spring cavity of the main valve through the orifice at the lower end of the main spool and the feedback pressure of the oil outlet cavity.Can not be transmitted to the pilot poppet valve,causing the pilot valve to lose its adjustment to the outlet pressure of the main valve;after the orifice is blocked,the main valve spring cavity loses oil pressure,making the main valve a direct-acting slide valve with a smaller spring force (only the main valve) Valve balance spring,therefore,when the outlet pressure is very low,the pressure reducing valve can be throttled by overcoming any force of the hairspring.
The pressure reducing valve is an important component of the hydraulic baler.When it has problems,you must pay attention to it.

In our daily life, we can often see hydraulic balers, and some companies still cannot do without it. Then we want to buy a hydraulic baler, what aspects do we need to understand?
1. You can find the products you need through the Internet. Generally, manufacturers who are capable of making hydraulic baler products will have their own official website. Through the official website product introduction, learn about the detailed parameters and introduction of each product, and the applicable industry. Working hours, etc., like hydraulic baler network, is the most professional industry website in China, users can learn more about each product above through the website;
2. Introduced by friends around you, such as your colleagues or users who have hydraulic balers around to learn about the performance of the baler, the failure rate, and the after-sales service of the manufacturer. These are often in reality. Problems encountered
3. Through industry websites, such as hydraulic baler net, China Packaging Net, China Hardware Net, China Paper Net, Global Hardware Net, etc., there are usually many manufacturers of hydraulic baler products, you can click to check it out. Learn more about hydraulic baler.
If you need a hydraulic baler, please visit the Nick Machinery website www.nkbaler.net, there are product pictures and videos, please click to watch! Or call 86-29-86031588, if you don’t understand, someone will be responsible for the explanation.
The straw silage baler is a kind of mechanical equipment that can be seen frequently. It is very convenient to use, can quickly pack the silage, and it is also very simple to operate. Do you know the correct operation method?
1. The operator of hydraulic equipment must understand the principle of the system, grasp the sequence of actions of the straw silage baler system and the adjustment methods of each component.
2. Before starting the equipment, check whether all movement organizations and solenoid valves are in the original condition, check the oil tank level, if the oil is insufficient, prohibit the engine.
3. The oil temperature of the straw baler is usually controlled at about 35 degrees. When the temperature in the oil tank does not reach a certain temperature in winter, it is forbidden to start performing the sequence of elements. The heater should be turned on for heating or the oil pump should be started. Let the pump run dry. When the oil temperature is too high in summer, a certain cooling method should be adopted. Pay close attention to the operation status of the system. If there is any doubt, stop the pump in time.
It should be noted that when the shutdown time of the straw silage baler exceeds 4 hours, the hydraulic pump should be idling for about 5 minutes before the equipment starts operation.
If you are interested in the above straw silage baler or have questions, please log in to our company's website: www.nkbaler.com, or call: 86-29-86031588
Nick brand clothing baler is recognized by many customers with its high-quality qualifications and professional craftsmanship according to everyone's actual needs, and is trustworthy.
We mentioned above that there are three reasons for the abnormal pressure of the garment Baling Press machine. Now let's talk about how to solve the abnormal pressure.
When installing and debugging the hydraulic pump, you must carefully read the instruction manual and strictly implement the installation and debugging process requirements. Confirm the suction and discharge ports of the pump, and be sure to fill the pump with hydraulic oil before starting the hydraulic pump. The oil inlet and outlet ports of the hydraulic pump must be well sealed and must not leak or enter air. If it is confirmed whether there is air ingress, grease the sealing part to see if the noise of the pump is significantly reduced to determine whether there is air ingress during pump operation.
2. When assembling the hydraulic pump for the garment baler, the cleaning and assembly process procedures must be implemented. For example, the blades in the vane pump must not be installed backwards, and the movement must be flexible. After the blades are coated with oil, it is appropriate that they can automatically fall into the rotor groove by their own weight. The processing, storage and transportation of the parts in the pump must strictly comply with the drawings and various technological requirements, and the inspection system must be strictly inspected before assembly. Unqualified parts cannot be installed on the pump.
Only when the pressure value of the garment Baling Press machine is in a reasonable range can the equipment exert its excellent performance and work more efficiently.
