Forklift hydraulic steering gear fault checking and removal

Forklift steering gear obstructs the signs: oil leakage inspection, valve body, diaphragm stator and back cover joint leakage, oil leakage at shaft strength, oil leakage at overflow valve;
Clearing measures: exchange the corresponding parts of the seal ring, wash the joint surface dirt, tighten the bolt check 2, limit bolt washers can not bend oil.
Removal Measures: Smooth or replace the gasket.
The forklift steering gear obstructs the signs: heavy steering and heavy inspections. 1. Fuel shortage in the fuel tank;
Clearing measures: Add hydraulic oil to the oil level to check the height of the oil, 2 to the disk rotation, and the cylinder does not move when moving, the suction pipe leak, the steering system atmosphere;
Removal measures: Exclude the atmosphere in the hydraulic system, replace the suction pipe inspection 3, slow turn to light, fast turn bias to heavy, the oil pump is not enough for reasons;
Clearing measures: The oil pump is not normal, the change of the oil pump is checked 4, the quick turn or the slow turn bias is extremely heavy, the steering is without pressure, the hydraulic oil viscosity is too large or the one-way valve fails due to the original cause;
Clearing measures: exchange hydraulic oil, wash the check valve of the steel, reload the steel ball to check 5, light the no-load steering, the load turns heavy, and the reason why the pressure of the overflow valve is low is caused.
Removal measures: Wash overflow valve and regulate relief valve pressure.
The forklift steering gear obstructs the sign: steering failure check 1, biased disk cannot be back to center, center pressure drop increases, spring sheet breaks lead to;
Removal measures: exchange of damage springs check 2, pressure swing significantly increased or can not be turned, pull off the pin or deformation caused by, or the joint shaft opening break or deformation
