How to solve the oil spill?
Two, body leakage oil Stem with the valve body sealing accomplished by type O sealing ring, if seal aging or damage, the system pressure under the action of the hydraulic oil to flow out along the valve stem, lead to oil leakage of the valve body. All you need to do is replace the o-ring seal.
The relief valve spring failed If the relief valve spring failure, hydraulic oil under pressure from below system regulation would have forced from ball valve position into the oil spill: and cause of leakage, make the system failure. The spring must be replaced and then adjusted to adjust the spring pressure to the specified 14 Mpa. Adjusted according to the 600 mm from the center of the load in demand load 7.5 t of the goods, when goods in seems up with locking nut locking, the pressure is needed to adjust the pressure. (4) multiplex valve stem cannot be reset If the stem is not reset, the groove is connected to the oil channel and the leakage is generated. One is that the spring force of the valve is reduced by means of the retainer or damage of the stem spring, and the stem shall not return to the original position, and the spring shall be replaced when repaired. Two, the valve body is not clean between the stem and the stem, which produces a large resistance, which makes the stem reposition difficult, and it is necessary to clean the inside of the multi-way valve to remove the resistance.
Internal leakage: It is common to cause the hydraulic cylinder of forklift truck to rise or fail to rise, and the fork of the fork falls on its own. The reasons for the leakage and the elimination method: (1) there is too much friction between the stem and the valve body The wear of the stem and body is accelerated due to the long-term use of the dispensing valve and the non-cleaning of the oil, which destroys the sealing surface of the valve and causes the leakage of oil. If the valve stem is worn lighter, it can be polished to the stem plate. If the stem is worn badly, it needs to be replaced (2) oil leakage between the body Failure of sealing ring to produce internal leakage; The valve body is damaged or damaged when installed, and it is easy to leak between the body when the oil pressure is applied. If the body damage is done, it is necessary to grind, replace the o-ring, and tighten the bolts in order and torque
Forklifts will run into a variety of problems, affecting both work efficiency and quality of work and causing unnecessary waste. However, before the problem occurs, the failure prevention measures of forklift should have a better effect on the occurrence of the failure. Here's a look at how forklifts can prevent oil spills. Measures to prevent oil spills: carefully dispose of various liners. Be like oil tray or valve cover cover, because contact area is big, not easy compaction, can cause oil leak easily. Tighten the nuts by the repair specification. The underpining of the padding will grease the oil; Too tight will cause the metal to bulge or twist the screw to cause the leak. Timely replacement of failure oil seal. The oil seal is improper, the shaft neck is different from the oil seal, it is easy to dump the oil because of the bias. Some after use for a long time, will lose elasticity, due to aging of rubber sealing lip crack damage or failure, since the tight spring will loss in sealing effect, should be in accordance with the standard repair or replace the qualified parts. Replace the badly worn machine parts in time.
Fix the main bearing in time. When the main bearing and shaft neck fit clearance is too large, before and after the sealing of the oil seal for crankshaft impact could lose caused by the oil from the crankshaft head leakage, or to the penetration of the clutch oil, thus pollution lining cause skid, job failure. Avoid the one-way valve and the ventilatory valve. This type of valve hole blocking easy cause box shell temperature, pressure, piston motion resistance, fuel consumption increase, oil and gas is full of the whole space, lubricating oil consumption increase and change cycle shortened. Properly handle all kinds of tubing joint seals. Tighten and press the nuts to seal and seal, after sealing or sealing the thin copper leather on two cones. Avoid hubcaps. Cavity should be adopted for the lubrication (namely adequate lubrication), dredge vent, the rational use of braking, strictly choose the high quality parts, and assembly and adjustment according to the process specification. Hopefully, the above points will help you to solve similar problems.
