LC type Roots oil pump maintenance method and application description
LC type Roots oil pump maintenance method and application description 1, often check the oil level position, if it does not meet the requirements, it must be adjusted to meet the requirements. When operating the LC type Roots oil pump, the oil level to the oil mark center shall prevail. LC type Roots oil pump maintenance method and application description
PP plastic, polypropylene, commonly known as "baijiao",Scientific name: polypropylene.
Description:
PP Plastic is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP Plastic don't have the problem of environmental stress cracking.Polypropylene (PP Plastic) is a semi-crystalline thermoplastic.PP Plastichas high impact resistance, strong mechanical properties, resistance to many organic solvents and acid and alkali corrosion.
PP Plastic is widely used in industry and is one of the most common polymer materials.
Australian COINS are also made of polypropylene.
Polypropylene bonding:
K-720 is suitable for polypropylene PP plastic adhesion, suitable for large area plate lamination, high transparency, suitable for PP adhesion PP, PP adhesive PC, PP adhesive ABS,PP adhesive PVC, PP adhesive acrylic, PP sticky metal, PP stick wood.
K-7007 adhesion performance is roughly the same as k-720, light yellow and more economical.
K-620 is adhesive small area polypropylene PP glue, must be used with the k-650 treatment agent, the instant positioning, the strength is high.
Advantages:
1. Low density;
2. Heat resistance ;
3. Non deformation;
4. High stiffness;
5. High surface strength;
6. Good chemical stability;
7. Nontoxic and safe.
Disadvantage:
The main disadvantage of the fault polypropylene is that the high temperature rigidity is not enough, and the low temperature is brittle.
Poor environmental tolerance, outdoor use, easy to turn yellow and brittle.
Tensile strength of anisotropy, the products are easy to deform, continuous use of low temperature, high creep performance, and long - term load.
Poor printing performance.
Application:
1,Valve part, drinking water and sewage water pipe,
2,Sealing element, spraying carrier,
3,Corrosion-resistant trough and barrel, industrial applications that have acid and alkali-resistant requirement; wastewater and gas discharge equipment for industrial purpose,
4,Scrubbing tower, clean room, semiconductor plant and other related industrial equipment and machinery, food machinery and chopping board,
5,Electroplating process, toy part
Combustion characteristics: PP Plastic easy to burn, polypropylene from continue to burn after the fire, with the top of the flame is yellow, the bottom made in blue, with a small amount of smoke generated, burning melt dripping, and oil.
Specification: the thickness of PP sheet material can be produced from 0.3mm to 2mm, and the PP sheet material is of rolling material and width of 500-1000mm.
The thickness of the plate can be produced from 2mm to 200mm. The specification is 600*1200mm 1000*1000mm 1000* 2000mm. Other specifications can be customized as needed,and The diameter of the PP rod can be produced from 2mm to 250mm, the length is 1 meter, PP rod can be ordered to be more than 3 meters in length.
Color: white and black, other colors can be customized
Modified varieties: PP sheet have various enhancers and other auxiliaries can be added to make modified varieties, depending on the requirements
Storage methods:
Keep in tight, cool and dry place to ensure good ventilation
Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
1. Check the oil level position frequently. If it does not meet the requirements, it must be adjusted to meet the requirements. When operating with the LC type Roots oil pump, the oil level should be the center of the oil standard.
2, the oil change period according to the actual use conditions and whether it can meet the performance requirements, etc., at the discretion of the user. General new LC type Roots oil pump, pumping clean and dry gas, it is recommended to change the oil after working for about 100 hours. After you can't see the black metal powder in the oil, you can extend the oil change period after Botai.
3, often check the oil quality, found that the oil should be replaced in time to replace the new oil, to ensure that the LC type Roots pump is working properly.
4. Under normal circumstances, the LC type Roots oil pump should be inspected after 2000 hours of operation, check the aging degree of the silicone seal, check whether the exhaust valve is cracked, and clean the dirt deposited on the valve plate and the exhaust valve seat. Clean the parts of the entire LC type Roots oil pump chamber, such as rotors, rotary vanes, springs, etc. Generally cleaned with gasoline and dried. After cleaning the rubber parts, dry them with a dry cloth. Carefully touch and hurt.
5. Add bearing lubrication oil to the bearing body. Observe that the oil level should be at the center line of the oil mark. The lubricating oil should be replaced or replenished in time.
6. Check the LC type Roots oil pump pipeline and joints for looseness. Turn the LC type Roots oil pump by hand to see if it is flexible.
7. After re-assembly, test operation should be carried out. Generally, it must be run for 2 hours and change oil twice. Because it will leave a certain amount of volatile substances in the LC type Roots oil pump after cleaning, it will be put into normal operation after the operation is normal.
8. Start the motor. When the LC type Roots oil pump is running normally, open the outlet pressure gauge and the imported LC type Roots oil pump. After it shows the appropriate pressure, gradually open the gate valve and check the motor load.
9, try to control the flow rate and head of the LC type Roots oil pump within the range indicated on the sign to ensure that the LC type Roots pump operates at the highest efficiency point, in order to obtain the maximum energy saving effect.
10. When the LC type Roots oil pump is to be stopped, first close the gate valve, pressure gauge, and then stop the motor.
11, LC type Roots oil pump during operation, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature must not exceed 80C.
12, LC type Roots oil pump in the first month of work, after 100 hours to change the oil, after each 500 hours, change the oil once.
13, often adjust the packing gland to ensure that the drip leakage in the packing chamber is normal (in order to drip out is appropriate).
