Maintenance of pressure reducing valve of hydraulic baler
Author : admin Time : 20-11-26 AllPageView : 539

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.

  • Routine inspection of NICKBALER brand automatic baler

    The automatic waste paper baler needs to be turned on and checked before it is used. It can be put into use after the startup and check everything is normal. The check contents are as follows:

    1. The location, temperature and cleanliness of hydraulic oil. Hydraulic oil is generally not a problem, so it only needs to be checked regularly.

    2. It is summer now, and the rain is relatively abundant. If the baler is placed outdoors, be sure to do a good job of coping with it before and after the rain. Such as: whether the circuit is smooth, whether there is water in the box

    3. Check whether the conveying of the conveyor is normal

    4. Look around the machine, comprehensively check whether the equipment is normal, and ensure that the work is correct before feeding.

    If the operator develops the good habit of daily inspection, it can not only maintain the normal production of the equipment, but also bring greater value to the production.
