Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] refer to figure 1 , is a schematic diagram of the external structure of the overall equipment of the present invention, including a base 1, a water tank 2, a magnetic float level gauge 3, an emptying pump 4, a filling pump 5, an electric control system 6, and a water storage skid 7, and a water tank is installed on the base 1 2. Filling pump 5, electric control system 6, what is stored in the water tank 2 is suppressing medium, and the liquid level of suppressing medium is controlled by magnetic float liquid level gauge 3.

[0021] The emptying pump 4 is an unsealed self-controlled self-priming pump, which has the characteristics of temperature resistance and pressure resistance, stable and reliable self-priming performance, long service life, small vibration, low noise, easy disassembly, and easy installation.

[0022] The perfusion pump 5 adopts an anti-corro...

Abstract

The invention discloses full-automatic pressing equipment for a detachable plate heat exchanger and a control method. The equipment comprises a PLC control system and an electric control cabinet controlled by the PLC control system, a plurality of electromagnetic valves are arranged in the electric control cabinet, the electromagnetic valves control first to seventh pipelines respectively to carryout full-automatic pouring, pressurizing, pressure maintaining, pressure releasing, back pumping and drying processes of plate pressure testing, and therefore full-automatic pressurizing testing of the detachable plate heat exchanger is completed. The electric control system is adopted to control opening and closing of the electromagnetic valve and starting and stopping operation of the electricequipment, errors caused by manual operation are greatly reduced, the full-automatic mechanical pressing process is achieved, the productivity is liberated, the production period is shortened, the operation precision is improved, and the detachable plate heat exchanger plate pressure test method is a great leap in the detachable plate heat exchanger plate pressure test technology.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a fully automatic pressing device and a pressing method for a detachable plate heat exchanger. Background technique [0002] The traditional plate pressure test is to manually pressurize the heat exchanger. After the filling is completed, the electric pressurization pump is used to pressurize to 1.5 times the design pressure, and then the pressure is maintained. Check whether there is any leakage, and then release the pressure manually. Discharge the pressing medium directly. Since this process is all manual operation, the production cycle is long, and the process precision is not high, which leads to the existence of disadvantages such as low production efficiency of the heat exchanger, high labor intensity of workers and difficulty in ensuring precision. Contents of the invention [0003] The invention provides a brand-new fully automatic pressing device and pressing...
