What happens when the 2X 70 rotary vane vacuum pump oil is much less in a short period of time?

The maintenance and maintenance of the 2x series rotary vane vacuum pump is as follows:

1. In addition to paying attention to Article 15, the rotary vane vacuum pump should pay attention to the following matters in its work:

1) The rotary vane vacuum pump must be kept clean at all times, and no other objects should be placed on the pump.

2) Pay attention to whether the belt tightness is appropriate, and adjust it once a year in the first half year.

3) Whether the pipe joint is leaking air and eliminate it in time.

2. After the rotary vane vacuum pump works continuously for three to half a year, the oil should be changed once, and the oil change time should be shortened according to the specific situation in areas with high humidity, the pump working in the wet season, or the pumped gas is polluted greatly.

The oil change is as follows:

1) Dismantle the rotary vane vacuum pump from the vacuum system, pad one end of the chassis motor higher, open the oil plug and drain the oil, rotate the vacuum pump, cover the exhaust port, so that all the dirty oil in the cavity is released from the oil drain port, and then add 100-500ml of new oil from the air inlet and continue to rotate more than 5-10 turns, clean the inside, operate 3-5 times according to this, after the special dirty oil is cleared, then install the oil drain plug, put the pump flat, add new oil from the air inlet and the oil filling hole, and the oil change is completed.

2) It is not advisable to start the motor for a long time when changing the oil, so as not to make the exhaust valve plate beat too violently and fatigue.

3) It is strictly forbidden to use kerosene, gasoline, alcohol, etc. to clean the pump without disassembly.

Rotary vane vacuum, his game will be able to detect what it is in a short time, so what's the situation?

Dear: I'm glad to answer for you, add about 5-10 liters of oil because of the shutdown state to add 1 2, that is, about 5 liters of oil, in the running state to 1 3, this level corresponds to the bearing ball 1 3 height, that is, about 3-4 liters, in fact, it is not so strict, add more regrets Jane friends will leak out of the acacia, add less, the oil in the oil cup will be automatically replenished. No more than 2 3 is appropriate, not less than blind 1 3, full oil heating is serious If the compressor is running, the oil level is less or you can't see the oil, but there is a return to it, after the shutdown, the oil is back to half or two-thirds is OK, if it is too low, you can re-add hope it can help you.

There is usually a maintenance manual.

The main thing is to look at the vacuum pump oil usage.

These pumps are crude but durable.

Summary. 2x30 rotary vane vacuum pump oil loss is too large? Often, large consumption of vacuum pump oil can be caused by persistent vacuum leakage and damage to the vacuum pump.

For example, on the Millrock LD85 freeze dryer, the vacuum level of the system should be able to reach 10MT, and the vacuum leak rate should be 30MT h in light rain. If the instrument does not meet the above parameters normally, it needs to be checked accordingly.

2x30 rotary vane vacuum pump oil loss is too large? Often, a large amount of vacuum pump oil consumption can be caused by continuous vacuum leakage and damage to the chain die and the vacuum pump. For example, on the Millrock LD85 freeze dryer, the vacuum level of the system should be able to reach 10MT, and the vacuum leak rate should be 30MT h in light rain.

If the instrument does not meet the above parameters normally, it needs to be checked accordingly.

1: The equipment is aging and the sealing is poor, which may make the lubricating oil enter the place where it should not enter, so the lubricating oil is consumed too quickly. 2：

The quality level of lubricating celery oil is not up to the standard, especially the high temperature stability is not good, and the evaporation rate of annihilation is accelerated when the temperature is slightly higher, so the lubricating oil is consumed too quickly.

The vacuum pump oil used in rotary vane vacuum pump, in addition to having the characteristics of the so-called lubrication, cooling, oxidation, oil-water separation and so on of general lubricating oil, emphasizes that in the low-pressure state, the light components are much less than the conventional oil, and the vacuum technology of Hochot is popularly speaking, that is, you will not pump out the oil and gas when vacuuming, in this way, your vacuum pump will quickly achieve the vacuum effect, and will not be pumped back and forth, the vacuum degree is always not up, which requires a high degree of oil refining, and synthetic oil should be used when necessary!

Horkodd Vacuum Technology (Shanghai) – rotary vane vacuum pumps should generally use rotary vane vacuum pump oil that meets the requirements of the SH0528-92 standard. Rotary vane vacuum pump oil with ISO VG100 viscosity at ambient temperature of 10 40. At an ambient temperature of 0 10, use vacuum pump oil with ISO VG32 viscosity grade.

When the vacuum pump is running, it is necessary to ensure that the oil level is at 1 2-4 5 of the height of the oil window. Oil levels and oil contamination should be checked frequently (weekly is recommended). If the oil level is too low, the rotary vane vacuum pump should be stopped, and the appropriate vacuum pump oil should be added to the height of the oil window at 4 5 places.

If the oil is contaminated, the oil will be blackened, emulsified, and thickened, and the oil should be changed in time.

Is it a vacuum pump for a vacuum packaging machine?

Vacuum pump oil pollution is a more common vacuum pump failure, vacuum pump oil pollution is not only as simple as polluting the vacuum pump, it will also affect the working efficiency of the vacuum pump, and even risk to the vacuum pump accessories. There are several reasons for vacuum pump oil contamination:

1.After a new rotary vane vacuum pump or vacuum pump is repaired, rinse the interior with water, fuel or cleaning agent.

2.Rotary vane vacuum pumps work in an environment that has a lot of water, dust or chemicals, which can also contaminate the vacuum pump oil.

3.The anti-rust inside the sealed vacuum pump is not unsealed and interferes with the operation of the vacuum pump oil, which also pollutes the vacuum pump oil.

4.When changing the vacuum pump oil, the old oil is not clean, the old is added to the new vacuum pump oil, the residual old oil pollutes the new oil, and the oxidation products of the old oil accelerate the oxidation of the new oil.

5.Work mistakes, when the vacuum pump oil is added in the vacuum pump operation, some other varieties or inferior imported vacuum pump oil are added, and the different formulations and additives of these lubricating oils may reflect badly with the original vacuum pump oil and are easy to deteriorate. Fact**: Howcht.

1.The rotary vane pump can pump water vapor, and it is best to add an ordinary filter screen before pumping to prevent hard impurities such as rust from damaging the equipment. During operation, the water vapor will be discharged, and the vacuum pump oil and water vapor will be separated without any problem.

However, it should be noted that before the equipment is turned off, it is best to run for half an hour without load to ensure that the water vapor and oil are completely separated.

2.The rotary vane pump can be kept in vacuum after it is shut down, but if the valve or flange is connected to the vacuum system, the vacuum level will be reduced. After the machine is shut down, it can be separated from the evacuation system.

The rotary vane pump itself can be kept in a vacuum state. The problem that the vacuum oil does not completely soak the rotary vane vacuum chamber is almost non-existent, because if you want to ensure the operation of the vacuum pump, you must ensure that the vacuum pump oil is sufficient, so that there must be lubricating oil filling and sealing between the selections.

1. Pump oil emulsification;

2. Connect the solenoid valve.

3. Chaomai vacuum provides consultation.
