Where an oil purifier is installed looks like a question of where to put things, but it is in fact a decision point shared by several parameters. Whether the machine goes into the oil tank room or the switch room, the length of the inlet pipe, the number of joints in the vacuum pipework, the electrical distance to the distribution panel, and the temperature and dust conditions of the room all change with it. Working through those before the position is fixed costs far less than changing it afterwards.
The position sets pipe length and the number of joints
Standing next to the oil source, the inlet pipe is short, there are fewer valves and joints along it, and therefore fewer places that can leak. The resistance on the suction side is low, the inlet conditions at the pump are steadier and the chances of gas locking and pump cavitation are smaller. The vacuum pipework follows the same logic: every additional joint in the extraction line is one more possible leak point, and the performance of a vacuum system is very sensitive to leaks.
The advantages of standing next to the switch room are exactly the reverse: the pipework has to be longer, and every extra length of pipe on the oil side needs insulation, fixing and routing planning, with the extra dismantling and reassembly work at maintenance time sitting in the same place.
The position sets the complexity on the electrical side
The ZYD-100 runs on three-phase 380V / 50Hz with a total power of 72 + 5 kW. The further the machine stands from the distribution panel, the more work goes into cable routing, cable tray, rodent protection and moisture protection; the closer it stands, the simpler that part becomes, but the capacity and the space on the panel side then have to be checked to make sure the load of a high-power machine can be connected at all.
There is one point that is easily overlooked: the control cabinet carries the operating panel, and people have to use it. In the switch room, maintenance staff walk further for every operation; in the oil tank room, the daily work of sampling, draining and changing elements is all within reach.
The position sets heat dissipation and the working environment
The installation space has to take the 1200×1400×1800 mm footprint and the approx. 720 kg machine weight, with room left for handling and for maintenance access. On ambient temperature, the TYA series is given a working environment range of -20~45 °C, and the margin for heat dissipation in a hot workshop is already thin; if the machine is then squeezed into a corner with poor ventilation, the temperature rise inside the cabinet becomes more pronounced.
| Choice of position | What it gains | What it costs |
|---|---|---|
| Close to the oil source | Short inlet pipe, few leak points, good inlet conditions at the pump | A longer electrical run and separate planning on the panel side |
| Close to the switch room | Short cables and few changes on the control cabinet side | Longer oil lines, and sampling, draining and element changes all take a longer walk |
| A middle position between the two | Neither the pipework nor the electrical run has to be stretched too far | Interfaces and maintenance space have to be reserved on both sides |
| A separate enclosure in a hot workshop | The local ambient temperature can be kept under control | Extra ventilation, insulation and power planning are needed |
Where the compromise lies
For most situations the answer is the middle position: the machine stands neither against the oil tank nor against the distribution panel, but at a point in between where neither the pipework nor the cables have to be stretched. When the position is being fixed, run a line for each of the three oil paths, the inlet, the vacuum return and the outlet, plus one for the power supply, count the joints on every section, and then check the room temperature, the floor condition and the access dimensions against them. The position can only be considered settled when all of these are satisfied together.
There is also a case where the choice does not have to be made between two positions: during a maintenance window, the machine can be wheeled to where the oil is. The TYG-100 is a mobile vacuum oil purifier with a flow rate of 6000 L/h and castors under the base, and the point of a machine like that is to move the question of position out of the selection stage and into the stage of use.
The position is not the most convenient corner on the drawing, it is the compromise at which the oil lines, the circuit and the working route all come out even.
