　　罗茨PROBURN中文免费版下载安装压力降低具体措施：

　　1.风量偏小

　　风量偏小和罗茨PROBURN中文免费版下载安装的间隙也很大的原因，间隙增大，内泄漏严重，就会产生风量减小的情况。同样道理，在输送气体的过程中，如果管道出现泄漏，也会产生风量减小的表象。风量偏小还有可能是因为管道阻塞引起，管道阻塞通常与高压、温度高并发，为防止管道阻塞的情况，定期检查罗茨PROBURN中文免费版下载安装的是非常有必要的。

　　Roots blower is a high-speed machine, so it will produce vibration, and because of the pulsation of its internal air, it also increases the vibration of Roots blower, so roots blower needs to be fixed on the ground during installation. According to different fan models, excavate a 150*150mm square 300mm deep square pit on the ground according to the size of the fan, and bury the anchor bolts, then connect the fan through bolts and nuts, and finally fill the square pit with cement concrete. After the concrete is fixed, tighten the nuts with force, so that the fan base and concrete are firmly connected together, so as to reduce the vibration displacement of Roots fan during operation, The operation safety of the equipment is improved, and the service life of the fan is greatly prolonged due to the reduction of vibration.

　　Installation skills and adjustment of Roots blower

　　1. Power cord installation problem

　　When wiring roots blower, it should conform to the rated working voltage of the blower. The voltage used is 380V, and it should not be connected to 220V working voltage. The wires shall not be connected reversely. After being connected reversely, the fan will reverse. If the fan turns incorrectly during the test run, it must be checked. If the check fails, the equipment will be damaged in a short time after the pipes are connected. For example, we once had a customer who failed to detect the test run because the wires were connected reversely, resulting in serious damage to the fan after running for about 10 minutes.

　　2. Installation platform problems

　　Generally speaking, roots fans should be installed on the platform above the ground, but it needs to be determined according to the actual situation. Some small models of roots fans do not need to be fixed, while some models of roots fans must be installed and fixed. Roots fans placed indoors are recommended to be installed according to the actual situation, which can be installed on the platform or on the ground. As for the roots blower placed outside, we suggest to install it on the platform, which can effectively avoid some external erosion.

　　3. Altitude during installation

　　If we have two disposal plants, and the altitude difference between the two places is large, the roots fans between them shall not be used interchangeably. Because the altitude is different, the roots fans of the same model cannot be used interchangeably. When selecting roots blower, we also need to determine the model of Roots blower according to altitude to ensure normal use.

　　4. Switch problems during installation

　　Generally speaking, the switch should not be far away from the equipment. Once the equipment is far away from us, it is inconvenient to control it in case of failure. The longer the failure time is extended, the greater the damage of the equipment is.

　　5. Air flow problems during installation

　　When installing roots blower, it's best not to have strong wind in the surrounding environment. Whether it's upwind or downwind, it will affect the suction and exhaust effect of the equipment. Therefore, controlling the air circulation around the blower can effectively prolong the service life of Roots blower.

　　Roots blower installation:

　　Roots blower is installed before leaving the factory. Only connect the inlet silencer with the inlet, the outlet silencer with the outlet, and then connect the outlet silencer with the pipe. Here are the installation precautions:

　　1. Roots blower shall be installed in a place with solid ground and sufficient space shall be left around for inspection, maintenance and repair.

　　2. The foundation level should be maintained under the roots blower base. It is recommended to pad damping rubber at the four corners of the base or cast and install with bolts to ensure that the roots blower operates smoothly and has little vibration.

　　3. The connecting pipe between Roots fan and system should be sealed reliably. For small vacuum pump, metal pipe connection gasket and oil resistant rubber can be used. For small Roots fan, vacuum rubber pipe connection can be used. The pipe diameter should not be less than the suction diameter of Roots fan, and the pipe should be short and less elbows. (when welding the pipeline, the welding slag in the pipeline should be removed, and it is strictly forbidden for the welding slag to enter the vacuum pump chamber.)

　　4. In the connecting pipeline, users can install valves and vacuum gauges above the air inlet of Roots blower to check the limit pressure of Roots blower at any time.

　　5. Connect the power supply according to the provisions of the motor label, and install the grounding wire and fuse and thermal relay with appropriate specifications.

　　6. When the roots blower is powered on for test run, the motor belt must be removed, and the vacuum pump can be put into use only after confirming that the rotation direction of the vacuum pump meets the specified direction, and the roots blower is used for reverse oil injection. (turn according to the direction indicated by the protective cover)

　　7. For Roots blower with cooling water, connect the cooling water as required.

　　8. If the solenoid valve is installed at the mouth of Roots blower, the valve and roots blower should act at the same time.

　　9. When the exhaust gas of Roots blower affects the working environment, a pipe can be installed at the exhaust port to lead away or install an oil mist filter.

　　Commissioning of Roots blower:

　　Roots blower commissioning includes: inching commissioning, no-load operation commissioning, full pressure commissioning and full system commissioning.

　　1. Inching commissioning refers to completely separating the fan from the system and disconnecting the inlet and outlet pipes of the fan on site. Turn the gear manually. After confirming that there is no jam inside the machine body, start the fan, then turn it off immediately, and then observe whether the rotation direction of the fan is the same as that marked on the machine body. If it is different, for three-phase motors, exchange any two-phase cables and reconnect them. Because the structure of Roots blower cannot be reversed.

　　2. No load operation commissioning refers to starting the fan and running it continuously for half an hour on the premise of inheriting the previous step and confirming the correct rotation direction of the fan, and observing whether the fan operates stably and whether there is abnormal noise and vibration.

　　3. Full pressure test refers to the installation of a valve at the outlet of the fan (to avoid noise, when a silencer is connected behind the valve), after starting the fan, apply a simulated load to the fan by gradually closing the valve until the fan pressure reaches the pressure shown on the nameplate, and then operate continuously for about 2 hours to ensure that the fan has no abnormal sound, The temperature is stable (after the fan is pressurized, the temperature rises gradually, generally as short as half an hour, as long as 2 hours, the temperature tends to stabilize and stops rising. If it continues to rise, there are mostly problems), and the fan current is within the range shown on the nameplate.

　　4. The whole system test refers to connecting the fan into the working system and starting the trial operation, which shall last for more than half an hour. Since the design is generally equipped with design allowance, the pressure and current of the actual operation of the fan after it is connected to the system should be lower than the pressure shown on the nameplate. If there is an overload condition, it often means that the selection is improper, and the problems need to be strictly investigated and analyzed.

If you want to know these knowledge, you can click here. If you want to purchase roots blower, you can contact our official customer service hotline.

　　Precautions and steps for assembly of three blade roots blower:

　　1. Precautions during assembly

　　(1) Check whether the disassembled parts are damaged. Pay special attention to the matching parts. If any damage is found, repair or replace it.

　　(2) The bearing should be cleaned and then coated with lubricating oil. When installing the bearing, tools, hands, etc. should be cleaned.

　　(3) Remove the dust from the fitting part, and then apply oil.

　　(4) If the sealing gasket is damaged or lost, replace the gasket with the same thickness and material.

　　2. Assembly steps

　　(1) Install the wall panel (front wall panel) on the drive side onto the housing.

　　(2) Install the impeller part into the casing from the gear end.

　　(3) Install the gear end wall plate on the housing, pay attention to the total axial clearance, and if it is not enough, the housing gasket can be selected.

　　(4) Assemble the front and rear bearings. When assembling the front bearing, the bearing housing should be filled with 1/2-1/3 bearing space grease.

　　(5) Assemble the gear.

　　(6) Install the drive side bearing and locknut together, and install the bearing gland.

　　(7) Adjust the clearance and drive in the locating pin.

　　(8) Install pulley and other parts.

　　Methods to quickly reduce the bearing temperature of three blade roots blower:

　　The bearing temperature of the three leaf roots blower will also be affected by the external environment. In winter, the room temperature is low, and the three leaf roots blower operates well (when the room temperature is 5 ℃, the front bearing of the three leaf roots blower is about 80 ℃). In summer, when the room temperature reaches more than 30 ℃, the front bearing of the three leaf roots blower rises with the room temperature above the set trip temperature. In order to avoid tripping, the crew installed spray water on the casing to cool down as an emergency treatment method, but the sanitary condition during operation is poor. Now several simple and fast methods are recommended.

　　1. Simple and practical is to install sunshades outside the fan, which is one of the direct methods of cooling.

　　2. If the temperature rise of axial flow fan, wear-resistant fan and other fans is too high, it is likely that the inlet and outlet pipe gates are not closed when the fan is started. Solution: Just close the inlet and outlet pipe gates.

　　3. In addition, due to the severe vibration of the box, the installation of the shaft and rolling bearings is skewed, the front and rear bearings are not concentric, and the fan rolling bearings are damaged or the shaft is bent, which are all factors affecting the fan bearing temperature. The solution: lubricate the lubricating oil in time to reduce the friction coefficient.

　　4. The motor belt is too loose. Here, pay attention to replace the motor belt in time, and adjust the position of the pulley to make it stressed evenly.

　　The above are the precautions and steps for the assembly of the three blade roots blower and the method to quickly reduce the bearing temperature.

　　Assembly sequence of Roots blower:

　　Roots blower separates the inlet and outlet with the help of engagement with two impellers, and pushes the gas in the cylinder volume from the inlet to the outlet without internal pressure in the process, so as to achieve the purpose of forced exhaust. Roots blower must be assembled before use, so as to ensure its normal operation.

　　1. Lift the casing onto the workbench, purge and repair burrs.

　　2. Install the wallboard at the drive end on the housing.

　　3. Push the rotor into the housing from the other end.

　　4. Assemble the side wall panel at the gear end; And ensure the total axial clearance. If the total clearance is not enough, the casing gasket can be selected.

　　5. Assemble the bearing seats and bearings on both sides. Determine the axial distribution clearance of the impeller.

　　6. Assemble the gear part and oil slinger. Pay attention to proofreading according to the marked mark. The conical surface of the gear shall not be oiled and shall be cleaned.

　　7. Assemble the gearbox.

　　How to operate roots blower safely:

　　1. Check the tightness of all parts of Roots blower and whether the locating pin is loose. If it is loose, it must be fastened.

　　2. The fan body shall be free of scale, rust and peeling. Prevent leakage.

　　3. When disassembling the machine, please measure the matching size of the machine, record and mark and guide the parts to ensure that the original matching requirements are assembled and maintained.

　　4. Sometimes the overload of Roots blower cannot be displayed immediately, so please pay attention to the changes of inlet and exhaust pressure, bearing temperature and engine power to determine whether the machine operates normally.

　　5. Under normal conditions, the equipment must be operated for 1000 hours to change the lubricating oil. Pay attention to whether the lubrication of lubricating oil is normal. Pay attention to the quality of lubricating oil. Always listen to the operation of Roots blower, whether there is noise or not. Pay attention to whether the equipment operates under the specified working conditions.

　　6. The new machine or modified roots blower will be put into operation according to the use procedure. It is recommended to replace all lubricating oils after 8 hours of operation. Routine maintenance is very important, and the fault must be repaired before use.

　　You must read the instructions carefully before operation to ensure that the staff grasp the useful use method of the equipment. Roots blower can operate correctly.

　　Specific measures for pressure reduction of Roots blower:

　　1. The air volume is too small

　　The air volume is too small and the gap of Roots blower is also very large. If the gap increases and the internal leakage is serious, the air volume will decrease. Similarly, in the process of transporting gas, if the pipeline leaks, it will also produce the appearance of reduced air volume. The low air volume may also be caused by pipe blockage, which is usually accompanied by high pressure and high temperature. In order to prevent pipe blockage, it is very necessary to regularly check the operation of Roots blower.

　　2. Causes of noise increase

　　The roots blower has been used for a long time, the overall compactness has decreased, the bolts have become loose, the silencer has aged, and the gap error between various parts has increased, resulting in the increasing noise of the roots blower.

　　3. Pressure reduction

　　The main reasons for the pressure reduction of Roots blower are: the gap increases, and the gap between impellers, between impellers and wallboards, and between impellers and casings increases. Roots blower is a mandatory gas transmission equipment, and the pressure presented by roots blower is the front resistance, that is, the back pressure we often say. The increase of gap will lead to serious gas backflow (increased internal leakage), resulting in the reduction of negative pressure and the appearance of pressure reduction. Other reasons for pressure reduction: the tightness is reduced. If there is gas leakage in Roots blower or pipeline, it will affect the pressure value of Roots blower. The leakage is serious, and the pressure naturally cannot reach the rated standard.
