What are the reasons for the destruction and deformation of the filter element in the four column hydraulic press machine?

The reasons for the damage or deformation of the filter element are: the filter element is blocked and the selection is wrong.  Elimination method: check the cleaning oil filter regularly in time;  Four column hydraulic press machine correctly select the pressure capacity, strength, flow capacity to meet the requirements of the filter, for a variety of special reasons to take the corresponding countermeasures.

How to prevent the filter of four column hydraulic press machine from dropping grain?

For the metal mesh filter, when the environmental temperature is high, the local oil temperature of the filter of the four column hydraulic press machine is too high, more than or close to the melting point of the welding point, plus the original welding is not firm, under the continuous impact of the oil will cause the welding point to fall off.

How to prevent the filter of four column hydraulic press machine from dropping grain?

Four column hydraulic press machine mostly use metal powder sintered filter.  After falling off particles enter the system, the throttle hole is blocked and the valve core is stuck.  The reason is that the quality of sintered powder filter element is not good, so it is necessary to choose qualified sintered filter.

How to prevent filter blockage of four column hydraulic press machine?

In the working process of the filter of the general four-column hydraulic press, the surface of the filter element will gradually heal, resulting in blockage is a normal phenomenon.  The blockage here refers to the serious blockage caused by the failure of the four-column hydraulic press machine.  After the blockage of the filter, it will at least cause the poor effect of the pump oil and the noise produced by the pump. The hydraulic system cannot absorb enough oil to cause the pressure of the hydraulic press to fail to achieve the desired effect.  A large number of bubbles and filter elements appear in the oil to increase the pressure of the hydraulic press due to blockage, resulting in the breakdown of the four-column hydraulic press machine.

What are the functions of the relief valve of SMC/BMC hydraulic press machine?

The pressure control valve relief valve, as an important index to measure the operation performance of SMC/BMC hydraulic press machine, plays a role of constant pressure relief, stability, system unloading and safety protection in hydraulic equipment.   Today we will talk about the role of relief valve on hydraulic press machine.

1. Regulating pressure overflow

SMC in quantitative pump hydraulic system under the condition of oil supply and throttling control of motor speed, always set the throttle valve and the speed controller in the oil, the part of the pump oil into the hydraulic cylinder for action, but the excess oil through the relief valve into the tank, the overflow valve is normally open state, the adjustable pressure regulating spring pre-tightening force, also can adjust the working pressure of the system.

2. Protect

When the system is refueling with variable pump, no excess oil must be spilled in the system, and its working pressure is determined by the load. At this point, the relief valve in parallel with the pump is only opened in overload, to ensure the safety of the resin well cover hydraulic press system.

3.Make the pump unloading

When the external port of the pilot relief valve is connected with the tank, the main valve column is quickly lifted when the inlet pressure is low and the energy loss is reduced by unloading the pump.After the electromagnet is energized, the control port outside the relief valve of the resin well cover hydraulic press is connected with the oil tank, so the pump can be unloaded.

4.Remote pressure regulation

When the external control of the pilot relief valve is connected with the relief valve with low pressure regulation, when the hydraulic pressure in the upper chamber of the main valve column reaches the adjustment pressure of the low-pressure valve, the main valve column overflows to realize remote pressure regulation.When the solenoid valve of the resin well cover hydraulic press machine acts at the right position without power, the outer port of the pilot overflow valve is separated from the low-pressure regulator, which is equivalent to plugging the outer port, and the pressure is regulated by the pilot valve on the main valve. The solenoid valve can conduct two-stage pressure regulation, but the pressure regulation pressure of the remote regulator of the resin well cover hydraulic press machine must be lower than that of the pilot valve.

5. Line forming back pressure

By setting the overflow valve of the resin well cover hydraulic press machine on the closing oil circuit of the hydraulic cylinder, the forward flash phenomenon of the hydraulic cylinder when the stroke back pressure of the closing chamber of the cylinder sharply reduces the load or becomes zero is eliminated, and the motion stability of moving parts is improved. Therefore, the valve for this purpose is also called back pressure valve.
