Abstract

Disclosed is a control system of an automatic press for polytetrafluoroethylene gaskets. According to the system, forming thickness of the polytetrafluoroethylene gaskets is set through an external key, acting time and pressure of an electronically controlled hydraulic cylinder are controlled by a single-chip microcomputer, a gravity sensor detects gravity of the washers formed by pressing to obtain density of the gaskets, data collected by the sensor are fed back to the single-chip microcomputer, data reference is provided for an operator by connection with a display screen of the single-chip microcomputer, a traditional complicated relay control circuit is improved, and automation level of the press for the polytetrafluoroethylene gaskets is improved.

Description

Technical field [0001] The patent of the present invention is a control system of a polytetrafluoroethylene gasket automatic press, which is applied to a polytetrafluoroethylene gasket automatic press. Background technique [0002] There are many ways to use PTFE as a sealing material. Because of its high corrosion resistance, stable physical properties, and high and low temperature resistance, it has achieved good sealing performance and is widely used in petroleum, chemical, pharmaceutical, electric power, and steel industries. Applicable media include almost all chemical components such as water, oil, acid solution, alkali solution, etc. PTFE gaskets are durable and reliable in sealing performance; PTFE itself has the best corrosion resistance and aging resistance, and has good creep resistance and cold flow resistance after special processing; it can be used in a wide range of It can be used safely for a long time within a certain temperature range; it is soft and easy...
