The pressure calibration of the equipment before delivery is not accurate, resulting in insufficient pressure. This helps the high pressure roots blower achieve efficiency. The oil level is too high. Select the content. The muffler is installed at the outlet, and the muffler is installed in the inlet and outlet pipes. The foundation surface shall be kept as horizontal as possible. The radial displacement of the synchronous gear fixed by the key is not more than 0.02m, the contact height of the tooth surface is not less than 50%, the tooth width is not less than 70%, and the top clearance is 0.2-0.3m (m is the modulus). The special shape design of the rotor keeps proper clearance between the rotors, greatly improves the sealing performance and further improves the operating efficiency.

外壳的进排气屏蔽线切入螺旋并随着转子顶部的旋转顺序打开。在深水高压条件下，保证通风。在空载状态下，启动电源开关以确认电机的旋转方向。检查仪表是否正常，发现异常及时通知维修人员更换。压力越高，问题越突出，高压领域的整体效率就越低。这不仅降低了风机降噪的经济成本和施工方便性，而且更有利于达到良好的噪声控制效果。

The air inlet and exhaust shield wires of the housing are cut into the spiral and opened with the rotation sequence at the top of the rotor. Ensure ventilation under high pressure in deep water. In the no-load state, start the power switch to confirm the rotation direction of the motor. Check whether the instrument is normal, and notify the maintenance personnel to replace it in case of any abnormality. The higher the pressure, the more prominent the problem, and the lower the overall efficiency of the high-pressure field. This not only reduces the economic cost and construction convenience of fan noise reduction, but also is more conducive to achieving good noise control effect.
