A forklift (forklift parts) stock folded his slow rise of reasons:
1, pump wear or leakage;
2, the distributor valve spring pressure is too low or the ball and valve seat wear and tear;
3, the distributor valve lifting and lifting cylinder valve stem clearance is too large;
4, the lifting cylinder and piston clearance is too large, or the seal of aging, damage;
5, the pipe or fittings leak;
6, one-way throttle valve can not be lifting fork failure reasons:
① tank short of oil;
② tubing connector plug or serious oil spills;
③ pump damage;
④ broken valve spring or permanent deformation;
⑤ door frame deformation;
⑥ poor hydraulic oil and so on.
Second, the forklift (forklift parts) Fork automatically upgraded reasons for the decline:
1, seal aging or damaged;
2, the lift cylinder and the gap between the piston is too large;
3, the hydraulic cylinder and distributor valve lifting lifting large gap between the valve stem;
4, the hydraulic cylinder and distributor valve lifting lifting large gap between the valve stem. |
