The relationship between the oxygen system configuration of the hospital and the oxygen side and the configuration of the booster equipment
Ø The technical indicators of the oxygen side determine the configuration of the oxygen system. It includes mainly oxygen flow and pressure. The pressure on the oxygen side is determined by the oxygen use in different places in the hospital. The oxygen use pressure of the general inpatient ward is ≤0.3MPa, and the oxygen pressure in the hyperbaric oxygen chamber and the operating room is relatively high, generally 0.5MPa.
The flow rate on the oxygen is determined by the number of beds in the ward, the operating room, the ICU, and the number of hyperbaric oxygen chambers. The calculation of the flow rate on the oxygen side is generally calculated in four ways: 1. The amount of oxygen per hour or daily is directly calculated by a readable number of meters such as a flow meter; 2. Some hospitals do not have a total flow meter, such as using liquid oxygen, According to the liquid level gauge on the liquid oxygen tank, the tank size is converted into the oxygen consumption per unit time under standard atmospheric pressure: 3. For new hospitals, the standard atmospheric pressure can be calculated by the number of beds, 1CU, operating room, and high-pressure oxygen configuration parameters. The maximum amount of oxygen used per hour: 4. the bidding documents or the hospital's clear oxygen configuration, to obtain the required model of oxygen equipment, the above four ways in the configuration of the oxygen system need to consider the surplus, The actual production of the oxygen generator should be more than the oxygen consumption on the oxygen side.
Ø Oxygen production characteristics of oxygen generator
The oxygen output pressure of the PSA oxygen generator is generally 0.4-0.45 MPa, and the outlet pressure has a certain relationship with the gas production. The premise of the stable operation of the oxygen generator is to set a stable outlet pressure, so as to ensure the oxygen flow stable.
Ø The configuration of oxygen booster equipment
If the oxygen boosting device is not equipped in the oxygen system, sometimes it can not fully meet the oxygen pressure demand in different occasions of the hospital. At the same time, because the oxygen consumption is not constant, the outlet pressure of the oxygen generator is unstable, which actually leads to the oxygen generator. The production of gas is reduced, ultimately jeopardizing the interests of customers, so it is necessary to equip the oxygen system with oxygen pressure equipment.
The purpose of configuring the oxygen booster is not only to meet the different oxygen pressure requirements of oxygen, but also to store oxygen and balance the amount of oxygen side to reduce the operating power consumption and the stable operation of the oxygen system equipment.
The configuration of the oxygen pressure equipment also needs to match the oxygen generator. If does not match, it will not bring benefits, which will affect the performance of the oxygen booster and the stable operation of the oxygen generator.
In general, the piston oxygen booster will have few leaks, as the equipment runs, the amount of leakage will increase, the gas production of the oxygen generator will also decay with the use time. The processing capacity of the rolling machine is the same as that of the oxygen generator, which will cause the rolling machine to start and stop, and the running time will be extended (limit the inlet valve of the rolling machine). Therefore, the configuration of the oxygen rolling machine should be less than the oxygen production of the oxygen generator. This will meet the hospital's oxygen demand, reduce equipment purchase costs, and reduce operating power consumption.
