Talking about the composition and wearing parts of Roots blower

Inquiry: Our company uses two CCR-150 Roots blowers from your company. Now we need to quote spare parts. Could you send me a spare parts list? The customer bought CCR-150 Roots blower at that time, and now he needs to make a list of spare parts, but he does not know what spare parts are needed and what vulnerable parts are. Therefore, let's discuss the composition and vulnerable parts of Roots blower.

The main engine of ordinary three leaf Roots blower mainly consists of the following components: casing, impeller (a pair), driving shaft, driven shaft, shaft sleeve, gear oil tank, gear (a pair), tooth end wall plate, drive end wall plate, driving bearing end cover, driven bearing end cover, bearing gland, bearing (4), sealing shaft sleeve (4), main shaft pulley, and other main components, including pressure plate Small parts such as exhaust gas, oil pointer, oil drain screw, and others such as sealing ring, round nut, stop washer, etc. See the following Figure Structure Diagram of Roots Blower for details.

Roots blower also includes base, motor, inlet silencer, outlet silencer, check valve, pressure gauge, V-belt, pressure relief valve, elastic joint, motor pulley, belt cover and anchor bolt.

Roots blower is a relatively sturdy and durable mechanical equipment with simple structure, low failure rate and few vulnerable parts. However, it is also related to user's operation and maintenance. Some customer companies have their own technical maintenance personnel, so they will purchase spare parts and consumables. What spare parts and consumables do Roots blower need to be replaced regularly? Now let's share with you. Main spare parts and wearing parts of Roots blower mainly include gear, bearing, V-belt, filter element (filter cotton) of air filter, etc.

Why talk about gears and bearings first? Roots blower is relatively durable and has been used for several years without problems. However, when the fan is running, the gear and bearing are running at high speed, and the wear of the gear and bearing will be a little more, so it is necessary to add gear oil to maintain the gear regularly, and add bearing grease to maintain the bearing. If there is enough lubrication, the wear of the gear and bearing will be smaller. If there is no lubrication or insufficient lubrication, the wear of the gear and bearing will be faster Quite serious, so gears and bearings shall be included in the spare parts list.

Then comes the filter element (filter cotton) of Roots blower inlet filter and V-belt, both of which are consumables. There will be dust entering the filter in the operating environment of the fan. The filter element needs to be cleaned or replaced regularly. After the fan runs for a period of time, the dust will gather in the filter element, affecting the air intake of the fan. In serious cases, foreign matters will enter, causing damage to the fan. If there is more dust on the site, the filter element will be replaced more frequently. There is also the V-belt, which is prone to aging after a long time of use. Another point is that when the fan is running, the belt is always in high-speed operation and friction. If the tension cannot be adjusted in time or the tension is not appropriate, the belt will slip, wear seriously, or even break. Therefore, the belt of Roots blower is also a consumable. Therefore, the routine maintenance of the fan can not only save costs, but also extend the service life of the fan.

After talking about spare parts and consumables, we will also talk about lubricating oil and oil seal. Although lubricating oil is not a part of Roots blower, it is consumable and indispensable. Customers often want to buy lubricating oil. We usually tell customers that the lubricating oil model is medium load 220 industrial gear oil, which is generally available in the hardware market, and can be purchased locally or from manufacturers. The oil seal of Roots blower that has been used for many years may also be eroded or corroded. When the equipment is repaired or the equipment needs to be replaced with spare parts, the oil seal should also be replaced together.

In general, whether Roots blower is more durable and what spare parts and consumables need to be prepared are closely related to user maintenance as well as fan quality. Therefore, when purchasing fans, users should make more comparisons and choose Roots fans with good reputation and quality.
