The heating system is controlled by 4 PTC heaters, 2 solid-state relays, 1 PLC, 1 touch screen and a temperature probe. The touch screen sets the process temperature, and the PLC and the solid-state relay perform PID adjustment by reading the actual value of the temperature probe to automatically heat to the set temperature; the temperature control range is +/-2 percent. The configuration of the air cooling system is as follows: the air cooling system is communicated to the interior of the casting machine through a heat-preservation corrugated pipeline from an air outlet of a refrigeration air conditioner to meet the requirement of temperature reduction, and automatic constant-temperature dehumidification is realized. The secondary temperature control system can accurately control the casting temperature of the ultrafiltration component, and avoids untimely solidification, poor sealing performance and difficult demoulding caused by too low temperature. The over-high temperature causes the solidification not in place, the assembly is scrapped and the like.
1. The PID is an abbreviation of the combined action of the specific column operation (P), the integral operation (I) and the differential operation (D). Wherein the proportional action is a proportional band operation established on a Set Value (SV),
here, the control variable (MV) is proportional to the deviation, providing a smooth control process without oscillations: the integration is an automatic correction process for the step deviation: both the proportional and integral effects are corrected by the control result,
and therefore inevitably produces a response lag. The differential action compensates for this drawback, and the response to disturbances can be accelerated by controlling the manipulated variable in proportion to the slope (differential coefficient) formed by the deviation.
AT means self-tuning, and when PID is executed, PID operation under the PID constant stored in advance by the user is interrupted, and after AT is executed, PID operation is started (restarted) based on the calculated PID constant.
Parameters for temperature system: p (%) is 20 to 60, I (min) is 3 to 10, and D (min) is 0.5 to 3.
2. TPO is a time division ratio output, used in combination with a PID calculation command, and converts a value obtained by dividing an operation amount by an operation range into a task ratio based on an input operation amount into a time division ratio output,
and (5) outputting pulses and controlling a Solid State Relay (SSR).
3. The epoxy casting time of the ultrafiltration membrane component is 8 hours, and the temperature is controlled at 25 ℃. The heating process is adopted at the temperature of more than 30 ℃ outside the room temperature, and the heating process is adopted at the temperature of less than 25 ℃.

5. the casting centrifuge is additionally provided with a heater, so that the casting time is reduced and the casting quality is improved;
6. the polyurethane is statically poured by using a vibration platform.
The casting seal material can be a curing product of a bi-component polyurethane adhesive, the bi-component is a component A and a component B, wherein the component A is an isocyanate-terminated polyurethane prepolymer, the isocyanate-terminated polyurethane prepolymer is a product obtained by reacting hexamethylene diisocyanate and polyethylene glycol adipate diol at a ratio of 1.5: 1 at 80 ℃ for 6 hours, the component B is a component containing active hydrogen, the component containing active hydrogen is polyoxypropylene diol, a catalyst dibutyltin dilaurate is added, the using amount is 0.5 per thousand of the total amount, and the bi-component polyurethane adhesive is prepared according to the following weight percentages: isocyanate-terminated polyurethane prepolymer: 38%, active hydrogen-containing component: 62 percent, and is mixed to prepare an adhesive, and then the adhesive is centrifugally cast and is cured for 36 hours at 60 ℃.
