MAINTENANCE METHOD OF PP WINDING FILTER

          When the PP winding filter is used to meet the design flow, then the filter needs to be opened after the shutdown to remove the filter element. Then you can use the water on the faucet to rinse the dirt on the surface, then soak for 24 hours, then immerse in 4% sodium hydroxide for 24 hours and then take it out, and then rinse it on the faucet.

         After the flushing is completed, you need to check the PP winding filter device for damage. For example, check whether the O-ring is damaged. If the O-ring is damaged, you need to replace the O-ring. At the last installation, you need to install the filter according to the method of filter installation. Rinse under less than 0.1Mpa pressure.

          If the filter element needs to be shut down for a long time after use, please remove the filter element, clean it according to the method described above, dry it and keep it properly, and use it again next time it is turned on.

What are the characteristics of Rail Freight & Intermodal?

  Rail Freight & Intermodal is one of the logistics transportation methods, so what are the characteristics of railway freight? The accuracy and continuity of railway transportation are relatively strong, and railway transportation is almost independent of the climate, so it can operate regularly, regularly and accurately regardless of day and night throughout the year.

      Rail transport is generally faster. Rail Freight can reach hundreds of kilometers per day, and the speed is much higher than that of sea transportation. The transportation volume is relatively large. A freight train on the railway can generally transport 3,000 to 5000 tons of freight, and these loads are much higher than air transportation and automobile transportation. The cost of railway transportation is relatively low, and the fuel consumption for transportation is about one-twentieth of that of automobile transportation.

      The transportation risks of railways are relatively reliable. Generally speaking, the risks are less than those of maritime transportation. Rail Freight generally needs to lay tracks, build bridges and tunnels, so road construction projects are relatively difficult and complicated, requiring a large amount of steel And timber, these artificial constructions help to protect the risk of railway freight from being much reduced.

What are the advantages of CNC Precision machining?

 CNC Precision machining is widely used in life. So what are the advantages of precision machining?

         CNC machining of precision hardware shafts has high precision and stable machining quality. Processing can be coordinated with multiple coordinates, so that parts with complex shapes can be processed. When CNC precision machining parts are changed, the CNC program needs to be changed This can save a lot of production preparation time. When machining workpieces, it is possible to produce more precise and highly precise workpieces.

         In addition, the accuracy of the machine tool is relatively high, so the general rigidity is relatively large, so you can choose a favorable processing amount to improve productivity. Generally speaking, if the machine tool has a high degree of automation, it can reduce the intensity of labor. In short, compared with traditional processing technology, precision metal processing can win from different aspects.

Maintenance and maintenance of high voltage cattle prod

First, through the general methods of wiping, cleaning, lubrication, adjustment and other equipment to maintain and protect the performance and technical status of the high voltage cattle prod, called equipment maintenance. There are four main requirements for high voltage cattle prod maintenance:
(1) Cleaning
The inside and outside of the equipment are clean and tidy. There are no oil stains on all sliding surfaces, lead screws, racks, gear boxes, oil holes, etc. The parts are not leaking or leaking, and the chips, debris and dirt around the equipment should be cleaned.
(2) Neat
Tools, accessories, and workpieces (products) should be placed neatly, and the pipes and lines should be organized.
(3) Good lubrication
Refueling or changing oil on time, continuous oil, no dry friction phenomenon, normal oil pressure, bright oil mark, smooth oil passage, oil quality meets requirements, oil gun, oil cup, linoleum clean.
(4) Security
Obey the safe operating procedures, do not overload the equipment, the equipment's safety protection device is complete and reliable, and eliminate unsafe factors in time.
The maintenance content of the cattle shock stick generally includes routine maintenance, regular maintenance, regular inspection and precision inspection. Equipment lubrication and cooling system maintenance are also an important part of equipment maintenance.The routine maintenance of equipment is the basic work of equipment maintenance, and must be institutionalized and standardized. For the regular maintenance of equipment, work quotas and material consumption quotas shall be established, and assessment shall be carried out according to the quota. The regular maintenance work of equipment shall be included in the assessment content of the workshop contract responsibility system.
Regular inspection of equipment is a planned preventive inspection. In addition to the human senses, the inspection methods must also have certain inspection tools and instruments. The inspections are carried out according to regular inspection cards. Regular inspections are also called periodic inspections. The mechanical equipment should also be checked for accuracy to determine the degree of accuracy of the equipment.
Equipment maintenance should be carried out in accordance with maintenance procedures. Equipment maintenance procedures are requirements and regulations for routine maintenance of equipment.Persistence in equipment maintenance procedures can extend equipment life and ensure a safe and comfortable working environment. Its main content should include:
(1) The equipment should be neat, clean, sturdy, lubricated, anti-corrosive, safe, etc., the working methods, working methods, tools and materials used, standards and precautions;
(2) The parts, methods and standards for daily inspection and maintenance and regular inspection;
(3) Check and assess the content and methods of the operator's maintenance equipment.
Equipment maintenance work should be assessed in conjunction with the enterprise production economic contract responsibility system. At the same time, enterprises should also mobilize the masses to carry out equipment maintenance work combined with special groups, conduct self-inspection, mutual inspection, and carry out equipment inspections.

WHAT FACTORS AFFECT FUEL OIL PRESSURE SENSOR?

          There are many factors that affect the stability of Fuel Oil Pressure Sensor. Generally, there is the structure of the pressure sensor. The design of the elastic components, housing, diaphragm, upper indenter and lower pressure pad of the sensor must ensure that the structure can not Relevant performance fluctuations should occur, or the performance fluctuations should be small, so when designing a pressure sensor, try to make the strain zone stress single and the stress uniform.

         The patch part is flat. Generally speaking, it is necessary to ensure the ability to resist eccentric load and lateral load on the structure, so that the installation force will be far from the strain zone, and the displacement of the load support point can be avoided during measurement. The pressure sensor is an assembly manufacturing product, so in order to ensure technical performance and long-term stability, it can be set into an overall structure in the initial stage.

          The metal material of the elastic element can play a key role in the comprehensive performance and long-term stability of the Fuel Oil Pressure Sensor. Therefore, it is necessary to select a material with high strength limit and elastic limit, low elastic modulus time and small residual stress caused by machining and heat treatment.

          Mechanical processing and heat treatment, during the mechanical processing of elastic components, because of the large residual stress caused by uneven surface deformation, the larger the amount of cutting, the greater the residual stress, so the residual stress generated by grinding It will be bigger. Therefore, the tempering process must be used to generate internal stress in the opposite direction, so that the residual stress can be offset with each other, thereby reducing the effect of the residual stress.
