Mechanical testing(spring force etc.).
Modifying spring force can adjust the on-off frequency.
Stepless adjustment of the spring force.
If the spring force is increased, this frequency will be boosted.
Retaining the spool orreturning to the de-energized position is the return spring force.
The spring force allows the use of doors with a width of 850- 1100 mm.
In this nut,which adjusts the spring force must be placed opposite the hinge.
Conservative forces include gravity,the electromagnetic force, and the spring force.
For example, for door closer door apecs The average range of spring force for the doors of apartments is 60-80 kg.
When the handle is released, the piston will absorb the grease oroil into the pump chamber by the spring force.
As long as the solenoid force overcomes the spring force and static pressure, the pilot valve core can be removed.
The inlet port of P andT outlet port is not through when the pressure at P port does not reach 90% of spring force.
Some cartridge valves are affected by internal physical forces such as spring force, pressure, differential pressure, or friction.
The inlet port of P and T outlet port is not through when the pressure at P port does not reach 90% of spring force.
The spring force is available to adjust by regulating the head hexagon of the direct operated relief cartridge valve with easy and flexible operation.
Therefore, the slope of the characteristic curve is determined by both the spring force and the hydraulic force. .
The spring force is available to adjust by regulating the head hexagon of the direct operated relief cartridge valve with easy and flexible operation.
The fluid force on the valve spool is direct equilibrium with the spring force in direct-acting relief valve.
When the pressure on inlet port drops, the spring force is larger enough to set the valve spool in the close position, but the spring force is available to be altered by adjustment of presetting pressure and changes different stiffness spring in order to alter the pressure adjustment range.
The ball comes back to its seat andstop the reverse flow while the pressure force gradually lower than the spring force.
The hydraulic solenoid valve parts assembly utilizes this force to overcome the spring force and the liquid force, to opens or closes the corresponding flow channel.
There are many types of test pins for different applications, differing in diameter, length,shape of contact head, spring force etc.
When the incoming hydraulic pressure rises to higher than the presetting pressure of spring force, the valve spool lifting and open the P port and the hydraulic oil is pressurized out from the outlet port T.
The piston is held by a spring which forces the valve to open when the pressure becomes greater than the spring force.
The hydraulic relief cartridge valve starts to overflow from P port to T port if the system operation pressure is rising to 90% of spring force and goes up until the main pressure achieving Max. setting pressure of spring. .
The hydraulic force generated on the lower side area of valve spool compares with the spring force, the spool is beginning to open when fluid pressure is larger than the spring presetting force, then the hydraulic oil flows to reservoir through outlet port T.
The hydraulic pressure on the side acts on the area difference of the poppet to overcome the spring force directly, drive the poppet up.
Once the pressure difference between the two main pipe up to 3.5~ 4.5Mpa,the piston IS to overcome the spring force to the right(left) movement, so that the travel switch contact closed, the signal to control the solenoid valve to switch, the reverse movement to complete a cycle of work.
In this way, after opening the check valve, the flow increases, the opening increases, andthe spring is compressed, the spring force does not rise too quickly.
Please refers to picture B,the valve spool is in the close position against the spring force, the oil port P and T is each isolated.
