HOWO dump truck hydraulic hand pump WG9719820001

Description

Introduction to hydraulic hand pump WG9719820001 for HOWO Dump Truck：

The hydraulic hand pump WG9719820001 is the most crucial component of the hydraulic lifting system of HOWO dump truck. Its main function is to control the inclination angle of the truck’s cargo compartment through the control valve in the driver’s cab, thereby enabling different levels of cargo discharge.

The main working principle of the hydraulic hand pump WG9719820001:

During the lifting process, the lifting pump conveys high-pressure hydraulic oil to the hydraulic cylinder. Inside the hydraulic cylinder, there is a piston and a piston rod, and the piston rod is connected to the tilting mechanism of the vehicle body. When the driver selects the lifting direction (rearward tilt or lateral tilt) through the control valve in the operation room, the hydraulic oil will flow to the corresponding hydraulic cylinder according to the operation, pushing the piston and the piston rod to move, thereby enabling the vehicle body to tilt at different angles and completing the unloading.

Manual Hydraulic Pump WG9719820001 applicable heavy truck models: Suitable for models such as SINOTRUK HOWO, SHACMAN DELONG, etc. Including specific models like HOWO T7H, HOWO A7, etc. It is a common cab lifting pump with features such as oil-proof, wear-resistant, and low noise.

Structure of the hydraulic hand pump WG9719820001:

1. Power mechanism: Usually driven by a motor or an engine to provide power for the lifting pump, enabling it to draw hydraulic oil from the oil tank and pressurize it to deliver it to the hydraulic system.
2. Pump body: The main part of the lifting pump, which contains various gears, pistons or blades, and through the movement of these components, it realizes the intake and discharge of hydraulic oil and generates high-pressure oil flow.
3. Control valve group: Used to control the flow direction, pressure and flow rate of the hydraulic oil to achieve smooth lifting, lowering and stopping operations of the cab or the vehicle body. For example, the distribution valve can distribute the high-pressure oil flow to different hydraulic cylinders to achieve different tilting actions of the vehicle body; the safety valve can prevent the system pressure from being too high, protecting the hydraulic system and vehicle components safely.
4. Pipes and connectors: Used to connect the lifting pump with hydraulic cylinders, oil tanks and other hydraulic components to form a complete hydraulic circuit, ensuring the smooth flow of hydraulic oil.

Fault Diagnosis and Repair of Hydraulic hand Pump WG9719820001

Fault Phenomenon: Press the handle of the lifting pump, but when there is no oil shortage in the lifting pump, it lacks force when lifting, and even after pressing for a long time, it still cannot lift. This might be due to the damage of the lifting pump or a problem with the conversion valve. If the lifting cylinder can rise but cannot lower, it might be a fault in the distribution valve.

Maintenance Method: For some simple faults, such as the damage of the rubber seal of the electric pump, it can be solved by disassembling the electric pump and replacing the rubber seal. If the internal components of the lifting pump are damaged, it might be necessary to replace the entire lifting pump assembly or undergo professional maintenance and repair.
