Good CapitaLand oil vacuum pumpsIn the process of use, due to inadequate maintenance or such and such problems lead to some failures, good Kaide, Leybold and other brands are no exception, have to be repairedYa Zhi RedIt is recommended to follow these steps:

1: Cut off the power supply and remove the vacuum pump from the vacuum system;

2: Use gravity method or pressure method to release and collect dirty oil to avoid polluting the environment;

3: Remove the belt and pulley key (two-stage rotary vane vacuum pump contains belt);

4: Disassemble the low vacuum end first, remove the rear end cover, and then take out the low vacuum rotor, rotary vane and spring, etc.

5: Remove the front cover and take out the high vacuum rotor, rotary vane and spring, etc.

6: Remove the sight glass, exhaust valve, exhaust cover, etc.;

7: Thoroughly clean the removed metal parts with gasoline and dehydrate them with alcohol. Rubber parts can be boiled with 15 sodium hydrofluoride water soluble to remove oil.

For burrs or rusty parts, you can use oil stone or metallographic sandpaper to gently grind to remove rust spots and burrs. The cleaned parts must be dried;

8: When assembling, install the stage first, lift the spring and rotary vane into the rotor, and then put it into the imported vacuum pump cavity, install the front end cover, and then install the positioning pin, and tighten the screws evenly and symmetrically. After assembly, the rotation should be flexible and uniform.

After installing the front rotor and the rear end cover, install the exhaust valve (the exhaust valve plate should be close to the valve seat) and other parts, such as gas ballast device.

Good CapitaLand screw vacuum pump.

Precautions should be taken when installing.

1.Good Cade.

Before the initial start-up of the progressive cavity pump, the mud collection tank and mud inlet pipeline should be cleaned to prevent stones, cement blocks and others falling during the construction.

Metal objects. Inside the crusher or pump. The pump should be operated only after opening the inlet and outlet valves and confirming that the pipeline is unobstructed, and the pump should be mainly concerned about whether the bolts are loose, whether the vibration of the pump and pipe exceeds the standard, whether the dripping water in the packing part is in the normal range, whether the temperature of the bearing and reducer is too high, and whether there is abnormal sound in each running part.

2.As a progressive cavity pump, the medium it conveys is returned in the pump.

Cooling and lubrication of the rotor, so it is not allowed.

idling, otherwise the stator and rotor will be damaged due to friction and heating. The pump should be injected into the suction end of the pump before initial use.

Fluid media. or lubricating fluids, such as aqueous or diluted glycerin.

Water glass, detergent, etc., in case the pump is in a frictional state during initial start-up. In the wastewater treatment industry, sludge or sludge sometimes occurs.

If large impurities in the scum (such as packaging bags, etc.) will be blocked in the suction pipe, these phenomena should be avoided during the day. If such a situation occurs accidentally, the pump should be stopped immediately for cleaning to protect the safe operation of the pump.

CapitaLand vacuum pump oil change is a common daily maintenance, but the more common the more should be done, the next to introduce to you the method and precautions of CapitaLand vacuum pump oil change.

How to replace CapitaLand vacuum pump oil:

1) The gravity method places the container below the oil drain port, unscrews the oil drain screw, and allows the old oil in the vacuum pump to flow into the container automatically. After the old oil has been drained, a small amount of clean vacuum pump oil is injected from the suction port.

100 500ml), rinse the inside of the vacuum pump chamber, and then, start the vacuum pump to run for about 1min, then turn off the vacuum pump, and release the injected new oil. If the released oil is still dry, new miscellaneous oil should be injected.

Rinse until clean. Then, screw on the oil drain screws. Unscrew the screw on the oil filling hole, add the pro-vacuum pump oil to the vacuum pump, so that the oil surface reaches the oil mark line, and then screw on the oil filling screw.

2) The pressurization method places the container under the oil drain port and unscrews the oil drain screw. Close the air extraction port and turn on the vacuum pump at the same time, open the gas ballast valve and cover part of the exhaust port of the vacuum pump to create a sufficient internal pressure for the dirty oil to be released quickly. Then, rinse the inside of the vacuum pump chamber according to method (1) and change the oil with new one.

Precautions for changing the vacuum pump oil:

1) Attention should be paid to cleaning to prevent dirt from mixing into the vacuum pump, 2) The vacuum pump should not be started for too long, so as to avoid fatigue due to the exhaust valve beating too dry and violent, 3) It is strictly forbidden to wash the vacuum pump with medium oil, gasoline, alcohol, etc., 4) The oil change is best carried out after the oil temperature rises, so as to make the visceral oil of the vacuum pump run out.

Maintenance method of good Kaide vacuum pump: Usually the operation of vacuum pump equipment is relatively simple, most of the normal production process does not need too much human operation, if the operator finds that the vacuum pump has abnormal conditions, in order to prevent accidents, the power should be cut off immediately, and the repair should be reported in time. During use, it should be avoided from direct sunlight and away from heat sources.

In daily work, the equipment should be inspected and maintained every day to keep it free of dust and debris to prevent debris from entering the pump. 1. When the vacuum pump is in normal operation and use, the following contents should be checked every three days: a. Whether the pump oil is within the range of the vernier b. Whether the pump oil has turned yellow and black, and whether it is turbid c. Whether the sound is abnormal d. Whether there is oil leakage during the operation of the vacuum pump 2. If the vacuum pump filters the metal mesh, it should be opened and cleaned every week to filter the debris.

The filter screen can not filter debris is to replace the filter and seal the gasket. 3. Instructions for regular maintenance of equipment: The pump oil is poor with the operation of the pump, so it is necessary to find out the degree of dirt and viscosity through the oil window, and replace the pump oil in time.

Pump oil change interval: oil change and cleaning every six months. The steps to change the pump oil are as follows:

a. Open the suction tube of the pump and let it start running after 5 seconds. The remaining oil in the pump is easily drained. B, first remove the exhaust pipe, open the oil valve, and then pour out the pump oil c, close the oil drain valve, the new vacuum pump oil from the oil filler injection d, if the pollution of the pump oil is very serious, you must add some new pump oil, through a few minutes of operation to make it clean, if the cleaning is not in place, must be repeatedly cleaned several times E, after the new pump oil, let the pump run on, and wait for the temperature to rise after confirming the vacuum ultimate pressure F, the maintenance process needs to clean the filter screen Fourth, operation instructions:

1) The vacuum pump produces high temperature (40 degrees to 80 degrees Celsius) in long-term operation. Therefore, after operation or just stop running, before the motor and pump body are cooled to normal temperature, do not touch the surface (2) In the event of an emergency during work, immediately turn off the main power supply and solve the warranty solution (3) If the equipment is abnormal, it should stop running immediately, and it is strictly forbidden to force irrigation, and continue to work with illness (4) It is strictly forbidden for non-maintenance personnel to disassemble the vacuum pump parts (5) The cloth strips and rags used in the maintenance equipment are placed in the specified stacking place to avoid debris from entering the pump.

There may be oil return phenomenon during the operation of the Kaide rotary vane vacuum pump, how to operate smoothly without oil return?Hochod Vacuum Technology recommends the following measures to prevent oil backflow from rotary vane vacuum pumps.

1. Separate the oil near the left side of the exhaust valve from other oils, and the oil level is only slightly higher than the partition wall.

2. Move the oil tank and exhaust valve to the side to reduce the oil level and reduce the oil volume.

3. Add a pipe to the oil hole so that the oil level is only slightly higher than the oil inlet.

4. Set up the check valve mechanism, and automatically close the oil inlet hole when the pump is stopped.

5. Set up the oil pump and auxiliary mechanism, and cut off the oil circuit when the pump is stopped.

6. The sealing part of the shaft seal should be reliable and replaced in a timely manner.

7. The plane of the valve seat should be flat, and the valve plate should be elastic.

8. The pump port is equipped with an inflation valve.

9. Loading into the mouth container.

Some customers are troubled by the problem of water ingress into the buffer tank of the vacuum pump when using the CapitaLand vacuum pump, and the following is what to do with the water inlet of the vacuum pump buffer tank told by the technical engineer of Yazhileide.

1. First of all, find the reason for the water inlet of the buffer tank of the CapitaLand vacuum pump: generally because when using the vacuum, the valve has a large opening and a high vacuum degree, resulting in water (or a large amount of water vapor) being pumped into the buffer tank, so that the water will enter;

2. The solution after water inlet is: open the outlet valve at the bottom of the buffer tank of CapitaLand vacuum pump and release water. In general, a small amount of moisture needs to be left in the buffer tank as a test of the tightness of the bottom of the buffer tank.

Good Kaide vacuum pump mainly uses water to seal to ensure that the water is constantly sealed, the sealing gasket at both ends of the vacuum pump is not dewed, the vacuum degree is no problem, the water quality must be good, otherwise the pump body will be scaled, the suction channel and exhaust channel impeller is getting smaller and smaller, affecting the vacuum degree, do these points are fine.

There is oil injection at the pump outlet: too much oil is added, reducing the amount of oil added. Pumping air from the air inlet for a long time should be avoided. ·

Fogging at the air outlet of the pump: Check whether there is air leakage at the air inlet and other parts. The vacuum is on the low side

Whether other light liquids are mixed into the pump chamber and oil, it should be properly operated for a period of time after the new oil change;Check whether there is air leakage in each sealing part of the pump; Calibrate the detection instrument.

Precautions for oil change of diffusion pump and oil booster pump: choose good quality oil; When changing the oil, all the old oil should be poured out; Clean all parts of the pump with solvent gasoline or special cleaning agent, wipe them dry with acetone or ethyl puzzle, dry them in the oven, or use a hair dryer to dry them; Install the internal and external parts of the pump according to the original part, and the nozzle should be in the middle of the pump cavity; The operator should wear white gauze degreasing gloves and pour diffusion pump oil or booster pump oil according to the required amount.

Problems arising from the use of diffusion pumps and how to eliminate them:

The vacuum degree is low, check the pre-vacuum;

Check whether the cooling water is smooth and whether the water temperature is high;

Whether the cooling water pipe is partially blocked;

The power of the electric furnace wire is too large or too small;

whether the supply voltage is low;

The injector is incorrectly assembled;

inaccurate regulatory measurements;

The meter or wire is not normal;

whether the vacuum system is leaking;

Whether the residual coating is too thick after long-term use in the studio;

The oil caused by improper operation is quickly oxidized, that is, it turns red or black, and the inspection work is to forget to turn on the cold water;

There is a serious air leak in the vacuum system;

When the diffusion pump is working, the atmosphere enters the diffusion pump;

There are volatile gases or dust entering the pump chamber in the working room;

Good CapitaLand Vacuum Pump Installation:Good CapitaLand vacuum pumpsInstallation of pumps and motors of accessories: When installing pumps and motors of vacuum pump accessories, before installing the vacuum pump and compressor, turn the coupling by hand to confirm whether there is any card and other damage in the pump.

Good CapitaLand vacuum pumpsPipeline installation between gas-water separators: the exhaust pipe of the vacuum pump or compressor is connected to the inlet pipe of the gas-water separator, the flange connection of the pipeline should be gasketed to make it reliably sealed, the inlet pipe of the vacuum pump or compressor should be equipped with a reservoir valve, and a pressure gauge should be installed between the exhaust pipe and the valve.

Good CapitaLand vacuum pumpsInstallation of the air-water separator of accessories: The air-water separator is installed on the foundation according to the outline drawing.

In the use of the pump, the vacuum pump oil is degraded and deposited, and there is the pollution of foreign substances, the performance is constantly declining, and the oil must be replaced after a certain period of time, and if it is still used, it will affect the normal performance of the vacuum pump. So how often should I change the vacuum pump oil?

According to relevant research reports, extending the oil change from 2,000 hours to 4,000 hours reduces pump life by 30%-50%. The experience of many enterprises with better vacuum pump management shows that the selection of high-quality vacuum pump oil and the reasonable oil change period can greatly reduce the failure rate of the pump and ensure good operation.

How often should I change the vacuum pump oil?

On the one hand, due to the promotion of environmental protection and energy saving, the performance of the vacuum pump is constantly upgraded, and its heat load and continuity.

Rising, coupled with the diversification of working conditions, makes the working conditions of vacuum pump oil more and more harsh, aggravates the degradation of oil, and shortens the oil replacement period; On the other hand, the performance of vacuum pump oil is improving more and more, and the quality is being upgraded.

Fast, so that the oil period increases, the total oil change period is extended. Recommended reading: Vacuum pump repair.

If the oil consumption is very large, new oil is constantly added in operation, and the new oil accounts for a large proportion of the lamp oil in the oil, and the amount of new oil added in the middle is greater than the oil change.

The amount of oil can not be extended by extending the amount of oil change, and the extension of the oil change period is not of much significance. Once, some oil change periods also take into account the consumption of vacuum pump oil.
