How to clean the filter element of a vacuum pump? The role of the filter element of the vacuum pump

1. Blockage. An effective way to solve the blockage is to install the vacuum pump exhaust filter, the vacuum pump filter element will definitely filter some impurities in the water or oil when working, and after installing the vacuum pump exhaust filter, it will absorb the debris in the oil in the water, so as to ensure that the Edwards vacuum pump works in a clean environment, and the vacuum pump will avoid blockage. In addition, in addition to the blockage problem, the vacuum pump filter element also needs daily maintenance and maintenance, the staff should listen carefully to the sound of the vacuum pump whether there is noise, check whether the vacuum pump filter element has impurities, check whether there are oil stains at the exhaust port, if there is an abnormal situation, the master should be immediately asked to repair or replace the parts.

2. Resistance. If you want to solve the problem, you have to get to the root of the problem. We have to find the cause of the blockage, what causes the filter to block, so that we can find each of the causes for each of them.

There are usually two reasons, one is a change in geometry. In this case, the filter element should be removed to see the degree of deformation, mild deformation can be slightly repaired before use, severe deformation should not be used again, otherwise it will aggravate the damage of the vacuum pump.

Another reason is that high-temperature oxidation and water droplet atomization cause impurity particles in the filter element of the vacuum pump, resulting in the resistance of the filter element. There are also some that are left over from cleaning. At this time, the filter element of the vacuum pump should be thoroughly cleaned, first use a brush or hair dryer to get out the impurity particles, and then clean it with a cleaning agent, so that no more impurities remain.

The vacuum pump filter element is a consumable material for the vacuum pump, except for the coarse filter element of the large filter two-stage filtration can be cleaned with citric acid, the others do not need to be cleaned, and the maintenance condition should be paid attention to, and the working condition is an important factor to extend the service life of the vacuum pump.

The cleaning of the filter element of the vacuum pump is also very simple, remove the filter element, and then rinse it with a water gun, and where there is debris, you can use tweezers to pull out the dirt, but if it is a missing star or a filter element made of gypsum, there is no need to clean it, and it will be scrapped directly and buy a new one.

There are three main filtration forms in the operation of imported vacuum pumps:

1. Air inlet filter: It can effectively prevent solid particles and fine ash from being sucked into the vacuum pump. Reduces mechanical wear and increases operational reliability. This extends the service life of the pump and protects the system components at the same time.

2. Exhaust filter: taking into account the exhaust resistance, dust holding capacity, and oil and gas separation performance, the requirements of the three are to achieve the optimal balance. Different internal and external positions should use different materials to achieve different separation purposes.

3. Oil filter element: used for lubricating oil filtration of imported vacuum pump and mainstream filter for extending the service life of oil, installed in the oil circuit.

The function of this machine filter element is as follows:

1. Prevent solid particles from entering the vacuum pump: The filter element can filter out the solid particles in the air, such as dust, sand, fiber deficiency, etc., prevent them from entering the vacuum pump, and reduce the wear and failure of the vacuum pump.

2. Filter out liquids and oil mist: In some applications, the gas may carry liquid particles or oil mist, and if these liquid particles or oil mist enter the vacuum pump, it will have a negative impact on the sealing performance of the vacuum pump. The filter element effectively removes these liquids and oil mist and keeps the vacuum pump in good working order.

3. Improve the work efficiency of the vacuum pump system: By filtering out the impurities and particles in the air, the filter element can keep the vacuum pump system clean, improve the exhaust efficiency of the vacuum pump, and improve the work efficiency of the entire vacuum pump system.

4. Maintain the stability of the vacuum level: The filter element can prevent impurities and particles from accumulating inside the vacuum pump, maintain the cleanliness of the system, so as to maintain the stability of the vacuum degree and ensure the stable operation of the vacuum pump for a long time.

Hello, the method is as follows: 1. The cleaning work of the vacuum oil purifier must be carried out in a state of non-operation, first of all, check whether the inlet and outlet pipelines of the oil purifier have been closed, and check whether the power switch has been closed. 2. After confirming that the power switch has been turned off, open the oil release valve and air release valve to let the residual oil in the vacuum filter flow out until the oil is completely clean. 3. Prepare the oil pan containing kerosene in advance, open the filter cover, take out the filter element of the oil purifier and put it in kerosene, soak it for about half an hour, rinse it twice with water and blow dry.

4. Use a brush to brush off all the deposits that can be seen on the filter, and then wipe them off with a rag. 5. Replace the filter element with the filter and tighten the bolts.

Air filter, installed in the air inlet, filters air droplets, oil separator core - drops for oil vacuum pumps, what kind of pump is your pump?

Vacuum pump filter element is a supporting product of vacuum pump, which is divided into vacuum pump exhaust filter, vacuum pump inlet filter, and vacuum pump oil filter.

The first is the vacuum pump exhaust filter, the vacuum pump exhaust filter is a device installed at the exhaust port of the vacuum pump, mainly to filter the oil mist generated by the vacuum pump in operation, on the one hand, to make the exhaust clean, and to achieve the purpose of fuel saving, improve the performance of the vacuum pump and extend the life of the vacuum pump.

The second is the vacuum pump inlet filter, which is installed at the air inlet to filter impurities in the air to avoid clogging or disturbing the precision system.

Finally, there is the oil filter, also known as the oil grid, which is the filter that filters the oil.

It is used to filter the air inlet empty. Prevent dust from entering the vacuum pump.

The vacuum pump filter element is the filtration equipment in the vacuum pump.

Vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to pump air from the pumped container to obtain vacuum. In layman's terms, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in an enclosed space.

According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas capture pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.

In order to purify the resources of the original fluid and the separation of resources and simple devices, the filter element is mainly used in oil filtration, air filtration, water filtration and other filtration industries.

The vacuum pump filter element is a necessary accessory for vacuum pumps, and many vacuum pump users do not know how often the vacuum pump filter element is replaced, and some even use it until the vacuum pump is abnormal. Abnormalities in the vacuum pump usually manifest themselves in smoke from the exhaust port or a sudden increase in motor current. If such a situation occurs, the vacuum pump filter element should be replaced immediately, but before these situations occur, the filtration effect of the filter element has changed, which has been affected, in general, the service life depends on the working conditions, before I saw an article "How often should the vacuum pump filter element be replaced?"

For the installation of the slide valve pump filter is a little troublesome, but some manufacturers are installed after delivery, saving the user's installation cost, but there are still many people interested in installation, or the manufacturer does not provide installation and delivery services, now find a picture here, I hope to help you.

There are many ancillary products for vacuum pumps, exhaust filters and intake filters are the most important ancillary products, in addition, there are oil filters and so on.

The exhaust filter is used in the exhaust port of the vacuum pump, the purpose is to filter the oil smoke, let the oil flow back, save costs, on the other hand, to ensure the cleanliness of the exhaust, through the inspection of the environmental protection department, and maintain the atmospheric environment of the plant.

The filter installed in front of the vacuum pump is the air intake filter, which is installed on the vacuum pipeline, in order to protect the vacuum pump from the damage of foreign substances and reduce the wear of the vacuum pump caused by impurities and dust in the air.

Therefore, the intake filter and the exhaust filter are equally important, and the combination of the two greatly improves the working efficiency of the vacuum pump and prolongs the service life of the vacuum pump. At the same time, the installation of an air intake filter can also reduce the burden on the exhaust filter and extend the service life of the exhaust filter.

Generally speaking, vacuum pump manufacturers will be equipped with air inlet filters (air filters), if there is no matching or later replacement, it is recommended to buy a filter produced by a qualified manufacturer in a regular channel.

Intake filter, inlet air filtration is more complicated.

In order to ensure product quality and maintain the safe operation of production equipment, the replacement of the vacuum pump filter element should be completed in detail according to the steps, and the production operator should record and supervise the replacement process.

After receiving the production instruction to replace the vacuum pump filter element, first make sure that the system stops running, prepare a suitable spare filter element, check whether the specifications, material, size, O-ring material, model and other data of the filter element are normal, and prepare disassembly tools, collection buckets, rags and other tools.

After that, the vacuum pump cartridge housing is thoroughly cleaned, and the area around the filter is emptied to leave the operating area. Bring protective gear. Disconnect the filter that needs to be replaced from the system.

Slowly open the exhaust port at the top of the filter, relieve the pressure on it, pay attention to safety in the process, prevent the splashing of materials or liquids, empty the materials in the filter, open the filter cover with a tool, take out the filter element of the Baker vacuum pump, and use a plastic bag to pack the filter element to be scrapped, use clean tools and rags to clean the inside of the filter, and wait for the new filter element to be installed.

Open the plastic bag at one end of the opening of the filter element, check whether the O-ring is intact and in place, and install the inflow of materials according to the method of flowing in from the outside of the filter element and flowing out from the inside of the filter element; Moisten the O-ring and the filter seat jack with a suitable wetting agent (such as water), hold the end of the filter element close to the O-ring, insert the filter element socket vertically into the filter element socket jack, insert the Baker vacuum pump filter element well, remove the filter cartridge bag, then install the metal cover, and tighten the filter with a tool; Close the filter drain port, open the air release valve at the top of the housing, and open the inlet valve slightly to let the material enter the housing until the liquid overflows from the air release valve at the top of the housing, at which point close the air release valve. Pay attention to check the disassembly place for leakage, and slowly open the filter outlet valve until it is fully opened. Indicates that the replacement is complete; Remove replacement tools and cleaning tools.

Cleaning the surroundings.

Vacuum pump filters require special attention when replacing them:

The pressure shock should be prevented, reverse pressurization should be prohibited, and when the pressure drop between the upstream and downstream of the filter is greater than or the flow rate drops significantly, the vacuum pump filter element should be replaced; When installing the filter element, attention should be paid to the installation direction of the filter element, which is outside in and inside out.
