Common faults of the throttle valve of electric hydraulic pallet truck manufacturers

by:Staxx Pallet Truck     2022-09-18

The throttle valve in the pallet truck manufacturer of the electric hydraulic pallet truck is to control the fluid flow by changing the throttle length or the throttle section. Parallel connection can be combined into a one-way throttle valve. But when we use the electric hydraulic pallet truck daily, the throttle valve will fail, which is very troublesome. Then, let's analyze the failure problem of the throttle valve for you.

1. Common faults of the throttle valve of the electric hydraulic pallet truck manufacturer

1. The flow rate of the throttle valve is unstable and fluctuates from time to time

2. There is little or no flow at the throttle valve outlet of the electric hydraulic pallet truck

3. The internal leakage flow increases

2. The manufacturer of the electric hydraulic pallet truck is faulty Cause Analysis and Diagnosis and Solutions

The flow rate of the throttle valve is unstable and fluctuates frequently

Cause:

The oil is mixed with impurities and is adhered to the throttle valve. On the edge of the orifice, the flow cross section becomes smaller, resulting in a slower flow rate; when the impurities in the oil are washed away, the flow cross section increases and the speed increases.

The temperature of the electric hydraulic pallet truck system rises, which causes the viscosity of the oil to drop, thereby increasing the flow and speeding up.

The damping device is blocked, air is mixed inside the system, and pressure fluctuations and jumps appear, making the speed unstable.

The internal and external leakage of the throttle valve is large, the flow loss is large, and the required flow cannot be guaranteed.

Diagnosis and solutions:

First disassemble and wash the throttle valve, clean the stains, and replace the filter. If the oil is seriously dirty, it is recommended to replace the oil liquid.

The manufacturer of electric hydraulic pallet trucks believes that certain cooling measures should be taken when necessary.

Check the gap between the valve core and the valve body. If the gap is too large, it is safer to replace the valve core.

Clean the throttle valve with damping device, and check that the moisture of the exhaust device is working properly. If it is not normal, it should be repaired and the air in the oil should be discharged.

There is no flow or very little flow at the throttle valve outlet of the electric hydraulic pallet truck

Cause:

The clearance between the valve core and the valve hole is too large, The leak is serious.

The orifice is blocked and the valve core is stuck.

Diagnosis and solutions:

(1) The manufacturer of electric hydraulic pallet trucks recommends to find out whether there is a serious leak, find out the cause, and then prescribe the right medicine.

(2) Disassemble and inspect the electric hydraulic pallet truck, clean the throttle port, replace the oil, improve the filtration accuracy, and keep the oil clean.

(3) Check whether the gap between the valve hole and the valve core is too large. If it is too large, the valve core needs to be replaced.
