Forklift gear pump drive system common faults and solutions

March 25, 2020

The drive system is one of the systems commonly used to forklift gear pumps, but also one of the systems it often fails, then what are the common failures of the gear pump drive system of forklift truck? How to solve it? ? With these questions, then we will introduce the forklift gear pump drive system common failures and solutions. Forklift gear pump drive system common faults and solutions First, the clutch slippage or non-separation, the failure of the reasons are: 1, the friction plate stuck on the oil or friction plate damage, this treatment is to clean the friction plate or replace the friction Piece; 2, the separation of bearings combined with pressure on the lever in the separation above, this approach is to deal with the split rod assembly rod length shortened; 3, the bearing clearance is too large, this approach is to divide the pump assembly Put the rod to be long; 4, oil in the air, this approach is to drain the air inside the oil; Second, the gearbox has abnormal sound, the reasons for the failure are: 1, excessive gear wear or bearing damage , This approach is to deal with gear change or replacement of bearings; 2, there are debris gearbox, the solution is to rule out debris.

PE Plastic Rod, full name is Polyethylene Rod.

Physical properties: PE  plastic Rod is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials, composed of ethylene polymerization, depending on the density is divided into high density polyethylene Rod, medium density polyethylene and low density polyethylene.


Classification of PE Rod
(1) LDPE Rod
       Low density polyethylene Rod (also known as high pressure polyethylene Rod)
       
(2) LLDPE Rod
       Linear low density polyethylene

(3) MDPE Rod
       Medium density polyethylene
       
(4) HDPE Rod
       High density polyethylene (also known as low pressure polyethylene)

 (5) UHMWPE Rod 

      Ultra high molecular weight polyethylene

 (6)Modified polyethylene Rod
      Chlorinated polyethylene (CPE) and crosslinked polyethylene (PEX)

 (7)Ethylene - ethylene copolymer
     Ethylene/propylene copolymer (plastic), EVA, ethylene, ethylene butene copolymer - other olefins, such as octene POE, cyclic olefin copolymer, ethylene/unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).
Polyethylene, which has a molecular weight of 3 million to 6 million, is known as UHMWPE.

Ultra high molecular weight polyethylene Rod is very strong and can be used for body armor.


Applications:
1. Papermaking industry: suction box board, scraper, molding plate, bearing, gear;
2. Mining industry: charging barrel, abrasive and adhesive-resistant back lining for warehouses;
3. Chemical industry: acid pump, filter plate, worm gear, bearing;
4. Food industry: packing machinery parts,   bottle guide, screw, wear plate, slide way, stud weld, roller and other transmission parts;
5. Textile industry:buffer board;
6. Food processing industry: chopping block, refrigerating plant;

7. Wharf: anti-collision board.


Advantages: 
1. Acid and alkali resistance, resistance to organic solvents 
2. Excellent electrical insulation and static resistance
3, Can still maintain a certain touness even at low temperature
4. Extremely high impact strength
5. Low friction coefficient
6. Non-toxic
7. Low water absorption
8.Lower density than any other thermoplastic plastics (<1g/cm3)

 Disadvantages:
 PE Plastic Rod have Weak mechanical property, air permeability, easy deformation, easy ageing, brittle, brittle less than PP, easy stress cracking, surface hardness, easy to scratch.
Difficult to print, in printing, surface discharge treatment, cannot electroplating, the surface has no luster.
       
       
Specification: the diameter of the PE rod can be produced from 2mm to 250mm. The conventional length is 1000mm, and the length is unlimited.
The thickness of PE Rod material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width cannot exceed 1200mm, the length is not limited.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 1000mm* 2000mm, and the commonly used specification of10-180mm is 600*1200mm.PE Rod can also be customized according to requirements, and the width cannot exceed 1200mm, and the length is not limited
 

Color: natural color is wax white, also can be customized black and color, the order of the color to order is 500KG.


Modified varieties: PE sheet/rod can be added to the fiberglass, copper powder and molybdenum disulphide to enhance the bar.
Add antistatic agent to the permanent antistatic electric bar, and the volume resistance value is between 6 to 9 power of 10.Add flame retardant to the flame retardant rod from UL 94V-0 to HB flame retardant grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.

Combustion characteristics:

Combustion situation: easy

Combustion flame status: molten drop, yellow lower blue

After the fire: continue to bur

Smell: the smell of wax burning

    

 Product certification: most environmental certification reports and safety reports for raw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
