1) When the valve core or push rod is radially clamped, the frictional force will increase. At this time, this resistance is opposite to the movement direction of the spool and the push rod, one of which helps to adjust the spring force to increase the oil pressure, and the other direction helps the oil pressure to overcome the elastic force and make the oil hydraulic The force is reduced, which reduces the sensitivity of the pressure relay.
2) Due to the deformation of the micro switch bracket or the loosening of the zero-adjustable part during use of the pressure relay, this will increase the minimum empty stroke of the micro switch that was originally adjusted or guaranteed after assembly and reduce the sensitivity.
3) If the drain cavity of the pressure relay is not directly connected to the fuel tank, our company mainly deals in stainless steel metal hoses and other products. Due to the high back pressure of the drain port, the sensitivity will also be reduced.
4) The micro switch part of the differential pressure relay and the oil drain cavity are separated by a rubber membrane. Therefore, when the oil inlet cavity and the oil drain cavity are reversed, the pressure oil will break through the rubber diaphragm and enter the micro switch part, which will be damaged Micro Switch.
5) Since the pressure regulating spring cavity and the oil drain cavity are connected, there is no sealing device at the adjusting screw. Therefore, when the oil drain pressure is too high, external leakage occurs at the adjusting screw, so the oil drain cavity must be directly connected back to the oil tank.
Charging Connector Plug is a tool for charging electric vehicles. With the popularization of electric vehicles, the electric vehicle charging gun will become a key point in the development of automobile industry and energy industry. The electric vehicle gun can solve the problem of fast charging, so as to achieve energy saving and emission reduction.
