The inlet of the screw blower is equipped with an air filter, which efficiently removes particles. The air filter element is located inside the casing and is easily removable for cleaning.And weTwin-screw blowerAdvanced processing technology, equipped with protective covers, easy to disassemble, all parts rotate smoothly without blockage, good lubricant sealing, no leakage.The screw blower's internal structure is compact, with daily maintenance conveniently accessible on the front of the soundproofing cover. This is because the back of the cover is the exhaust outlet, allowing the machine to be installed side by side for better space utilization.

  The screw air compressor provides oil-free air and operates stably in extreme conditions.Screw blowers offer superior adjustment capabilities compared to other blowers, with reasonable operation and running methods. Even in the event of an accident, they come with good protective measures.The oil level of the screw blower can be easily observed from outside the sound-insulating cover, eliminating the need for shutdown inspections. It is also highly portable due to its integrated design, allowing for direct forklift transport.

AfterEditorMultiple major repairs and...Engineers are conductingCommunicationTwin-screw blowerThe primary causes of equipment failures include broken shafts, bearing damage, excessive vibration, rotor lock-up, and shaft seal leaks. The main failures leading to increased overhaul frequency are rotor lock-up and friction.

Friction between the rotor and the housing or between rotors.Twin-screw blowerCommon malfunctions include... If such a malfunction occurs during operation, it will be accompanied by severe vibration and noise.Twin-screw blowerAfter a prolonged shutdown, frequent occurrences of the rotor becoming stuck have been reported.EditorHere we goFaultThe primary reasons are summarized into the following categories.

　　The gap between the impeller blade and hinge is not appropriate.

The blades and hinges of the impeller are not properly spaced, and their gaps change during operation. When both rotors rotate at low speeds, collisions occur, leading to friction between the rotors and even potential jamming.

If this fault occurs during operation, it can cause collisions between the two rotors or between the rotors and the housing, resulting in a loud impact noise. As the vibration intensifies, it may even lead to base vibration; at the same time, the temperature of the friction area rapidly rises, sometimes even causing the casing to burn red.

　　Bearing Failure

Poor fan operation, worn oil seals, and excessive assembly gaps may all lead to bearing damage. This can cause an increase in temperature, as well as the temperature of the bearing housing. In severe cases, the bearing housing may deform.

Especially during the locking process of the inner and outer rings of the bearing.Twin-screw blowerThe bearing seat and side cover plate are subjected to significant external force, leading to high temperatures. Uneven heating of the bearing seat and side cover plate can result in deformation and cracking of the side cover plate in severe cases.

Diameter wear causes excessive clearance between the shaft and the inner race of the bearing, while wear on the bearing housing leads to excessive clearance between the housing and the outer race of the bearing, which can result in the rotor becoming stuck or experiencing friction. Particularly for belt-connected fans, the driving shaft is subjected to the tension of the belt, causing the bearing housing to be subjected to force in one direction, making the bearing housing on the belt side of the driving shaft prone to uneven wear.

　　Gear wear

Gear wear and increased gear side clearance can alter the position of the two rotors, reducing the hinge clearance between the driving and driven rotors and expanding the blade clearance, leading to mutual collision and friction between the two rotors.

　　Rotor Housing Warping

If the rotor or housing deforms, the clearance between the rotor's outer diameter and the housing will be too small, leading to the rotor's frictional jamming.

　　The clearance between the rotor end face and the side cover plate is minimal.

Twin-screw blowerWhen the gap between the rotor and side cover plate is too small, debris is forced into the gap; or, after the axial positioning bearing wears out, the axial movement of the rotor increases, leading to friction between the rotor and the side cover plate, causing the rotor to become stuck.
