(1) constant filling fluid coupling were full of oil, the temperature of the oil expansion will seal Dingfan, break the seal, they may even coupling housing Splitting.hydraulic hose fitting

(2) in order to start or overload time limit torque rise limit of the auxiliary chamber before the rectangular fluid coupling mostly set side auxiliary chamber, after the auxiliary chamber, at the start or overload through the shunt to the auxiliary chamber, so as to reduce the working chamber the full-charge rate to the low transmission torque. If the coupling cavity is wholly filled with oil, during normal operation, these auxiliary chamber is full of oil when starting or overload, the working fluid can not be diverted from the working chambers, which can not reduce the filling rate of the working chamber of the coupling, also unable to reduce the transmission torque coupling lost overload and delay start function. Constant filling fluid coupling fluid-filled, must be in accordance with the regulations and must not be completely filled.hydraulic fittings suppliers

(3) The test proved that constant filling flu id coupling 80% filling rate has reached the maximum transmission power, filling rate of more than 80% of the power, not only can not improve, they may reduce the power.hydraulic fittings manufacturers
