Construction Machinery Hydraulic Piston Pump, designed specifically for the main hydraulic systems of heavy-duty tracked construction machinery such as excavators, loaders and bulldozers, is the power core component of the hydraulic system. It efficiently converts the mechanical energy of the engine into hydraulic energy, providing stable and continuous high-pressure oil for all equipment actions such as boom, arm, bucket, travel and slewing, ensuring reliable operation of the equipment under heavy-duty and harsh working conditions such as mines and construction sites. The housing of the product is made of high-strength cast iron, integrally formed by casting process with dense and defect-free blank structure, excellent strength and rigidity, which can withstand high-pressure impact and alternating loads without deformation or cracking. The surface is treated with yellow anti-corrosion spray paint with strong adhesion, excellent weather resistance and corrosion resistance, which can effectively resist moisture, dust and corrosive media, extending the service life of the product.
The internal core components such as cylinder block, pistons, valve plate, retainer plate and main shaft are made of high-quality alloy steel, strengthened by multiple heat treatment processes such as forging, quenching and tempering, high-frequency quenching and carburizing, with high hardness, excellent wear resistance and fatigue resistance, which can withstand wear and impact under high pressure and high speed conditions for a long time, greatly extending the service life. Key mating surfaces such as pistons, valve plate and main shaft are precision polished/ground with high dimensional accuracy and low surface roughness, with reasonable fit clearance, reducing friction resistance, improving volumetric efficiency and transmission efficiency, and reducing energy consumption. The pump body is integrated with valve groups such as pressure compensation and flow control, which can automatically adjust the displacement according to the load, achieving a balance between energy saving and high efficiency. Built-in high-quality seals, resistant to high pressure, oil and aging, can effectively prevent hydraulic oil leakage, ensuring stable system pressure and reducing maintenance frequency. The product has passed strict factory tests, including pressure resistance test, flow test, leakage test, etc., to ensure that all performance indicators meet the original equipment standards. At present, this model of hydraulic pump is in stock, which can quickly respond to orders and provide stable supply guarantee, making it an ideal accessory for the maintenance and repair of construction machinery in mining, construction, water conservancy and other fields.
