Commissioning of the surge tank
Set the pressure, follow the high to low criteria, according to the process one by one, namely: blocking pressure - release pressure - operating pressure setting pressure, follow the high to low criteria, according to the process Carry out, ie: blocking pressure - release pressure - operating pressure (a) set pressure, in accordance with the high to low criteria, according to the process one by one, namely: blocking pressure - release pressure - operating pressure.

(2) After the pressure is set, it is necessary to check the closing pressure and verify its function, and whether it reaches the demand value.
(3) After the pressure setting meets the demand, the outlet valve can be opened. Before then, the outlet valve should not be opened to prevent accidental attack.
(4) Fine appearance should pay attention to maintenance, in order to prevent the pressure from shaking and damage the appearance.
(5) In the commissioning of 1+1 pressure regulating equipment, if uninterrupted air supply is required, the pressure should be manually controlled by bypass, the pressure regulating valve should be operated by one hand, and the pressure gauge should be hand-held, and the time should be investigated to change the pressure to maintain the outlet pressure. Within the pressure range, after the pressure regulator pressure setting is completed, slowly open the regulator outlet valve, and then close the bypass valves after the regulator is normally supplied with air.
(6) If the regulator adopts 2+0 one open and one closed type, both roads need to be debugged, open one way, close one way (standby), the air pressure between the inlet and outlet valves should be vented in the spare road to avoid the pressure regulator film and stretch The spring is pressed and becomes tired.
(7) If the regulator port uses two channels to actively switch the air supply, the pressure parameters should be set according to the main and auxiliary roads, then the two inlet and outlet valves must be fully open, and the active switching has higher requirements on the function of the regulator, usually The voltage regulation accuracy is ≤2.5%, and the sealing precision is ≤10. Check the active switching: the main road pressure is improved (imitation fault), the main road pressure is too high and the intercepting valve action, blocking the main road gas, suspending the gas supply, and investigating whether the auxiliary road can complete the self-starting gas supply according to the set pressure. After the inspection is passed, the main road blocking valve is reset, and the pressure of the main road regulator is adjusted back to the original set value, so that the pressure of the main and auxiliary two-way regulator is set, the main road is mainly supplied with gas, and the auxiliary road is used. Standby, when the main road is out of order, the auxiliary road regulator starts its own operation without interrupting the supply of gas. This method is commonly used in the public welfare and industrial and commercial gas supply.
(8) Series monitoring and voltage regulator debugging The series monitoring of the voltage regulator is mostly controlled by the method of monitoring, that is, the monitoring regulator is fully open.
1. First check whether the pressure signals of the two regulators (or pilots) are correct. If the pressure signal tubes are connected behind the operation regulator, they are correctly connected.
2. Press the pressure regulator springs of both pressure regulators to the pressure regulator spring of the tightest front pressure regulator (monitoring pressure regulator) to make the pressure of the rear stage to the blocking pressure and debug the blocking valve. 3. Commission the release valve.
4. Then adjust the pressure regulator of the front pressure regulator (monitoring regulator) to make the center pressure to the outlet pressure setting value +10%.
5. Adjust the tension spring of the post-release regulator (operating regulator) to set the post-stage pressure to the outlet pressure setting (the center pressure will rise to equal the inlet pressure at this moment).
