hello i have four dpg + 64-1 mounted together on a voltage test machine, they work simultaneously. tell me is it correct to connect them together with the vents? what purpose are the vent holes? faster work?have You got any graphs with correctly mounting 4 pieces together?
The DPG+ series parallel grippers are sealed units that are used in hazardous environments. They have a IP67 rating and can work in wet conditions and even be submerged to a shallow depth. The vent port allows for pressure balance inside the gripper jaw area as the gripper opens and closes and displaces air. There are 3 ways to use the vent; 1) If the environment is mostly clean, a sintered or mesh filter can be installed to allow the internal area to vent to atmosphere. 2) If there is fluid in the environment such as splashing coolant then a tube can be installed in the port that vents to a clean dry area away from contamination. 3) If the gripper is exposed to heavy coolant flow or submerged in fluid then we recommend air pressure be applied to slightly pressurize the internal area to prevent fluid ingress around the seals as the sliding jaw moves through the seal. The 4 gripper vent ports do not need to be daisy-chained together. If it makes sense to do that then use T fittings at each gripper and connect a common tube between them. In this case of testing electric connections in a clean environment the port needs only a sintered or mesh filter installed.
@@SCHUNKUSA Hello! thank you for the quick reply. our grippers work very quickly in a dusty environment - the tested material crumbles. The machine was built by Korean engineers, unfortunately I do not have contact with them. Is it possible in the case of dust as well as in the case of immersion, it is possible that they connected 4 grippers together to give a slight pressure to the guides to reduce the risk of particles from the environment fudging into them? I will add that the dust is really fine. Once again, thank you very much for your interest in my question and I send greetings from Poland.
Yes, the S-ports can be connected together and pressurized simultaneously. Note that we recommend low pressure on these ports, 7-14psi (0.5-1.0bar). The valve used for this circuit should be a 3-way, 2-position so that it is normally closed electrically open. There is a reason for this. When the grippers are closing, the S-circuit should be open to atmosphere so the displaced air inside the gripper can escape. We have seen times where the grippers will “chatter” when closing if you have pressure on the S-port. Once the grippers are closed, reapply pressure to the S-port.
Nice explanation. Thank you.

@@SCHUNKUSA cheers mate! I understand all now👌😊
