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.

外殼的進(jìn)排氣屏蔽線切入螺旋并隨著轉(zhuǎn)子頂部的旋轉(zhuǎn)順序打開,。在深水高壓條件下,，保證通風(fēng)。在空載狀態(tài)下,，啟動(dòng)電源開關(guān)以確認(rèn)電機(jī)的旋轉(zhuǎn)方向,。檢查儀表是否正常，發(fā)現(xiàn)異常及時(shí)通知維修人員更換,。壓力越高,，問題越突出，高壓領(lǐng)域的整體效率就越低,。這不僅降低了風(fēng)機(jī)降噪的經(jīng)濟(jì)成本和施工方便性,，而且更有利于達(dá)到良好的噪聲控制效果。

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.
