description

The HVP116 pilot pump adopts upgraded reinforced integral gear pump structure, professionally optimized for frequent start-stop, variable load switching and continuous medium-duty operation characteristics of general construction machinery hydraulic systems. Different from ordinary low-precision pilot pumps with easy wear and fast pressure attenuation, this model adopts unified industry-standard installation dimensions and hydraulic calibration parameters, with ultra-low internal leakage and linear stable flow-pressure output. Equipped with high-hardness wear-resistant alloy gear pair, fatigue-resistant bearing assembly and high-temperature aging-resistant composite sealing system, it can maintain stable pilot pressure output for a long time under long-term cyclic hydraulic impact and high-frequency compound action switching. The high-rigidity one-piece pump body has outstanding vibration resistance, dust resistance and sediment corrosion resistance, perfectly adapting to municipal engineering, earthwork construction, road renovation and other complex and harsh working environments.

advantages

Adopting industry-standard universal calibration parameters and installation dimensions, it supports 1:1 non-destructive plug-and-play replacement for multiple mainstream construction machinery models, no equipment modification required, with wide compatibility and zero adaptation faults.
Optimized low-pulsation constant-pressure output technology effectively suppresses pilot pressure fluctuation and pressure drop caused by frequent load switching and compound actions, solving common problems such as slow equipment response, weak operation and working jitter.
High-hardness alloy gear pair and reinforced bearing structure effectively improve wear resistance and structural stability, adapt to long-term high-frequency start-stop and variable-load operation, and maintain long-term stable pilot pressure output without attenuation.
High-quality anti-aging and high-temperature resistant sealing system resists long-term hydraulic cyclic impact and temperature changes, completely eliminates oil leakage and system pressure loss, and reduces daily equipment maintenance costs.
Integral high-rigidity pump body features excellent vibration, dust and corrosion resistance, adapting to various complex and harsh construction environments, with service life significantly longer than ordinary universal pilot pumps.

FAQ

Q1: What are the common failure symptoms of HVP116 pilot pump?
A: Typical faults include delayed operation response, weak boom/arm/bucket compound actions, unstable idle pilot pressure, walking jitter and deviation, unsmooth swing actions, slow main pump variable response, pump body oil leakage and abnormal operating noise.
Q2: Why does the equipment become sluggish after long working hours?
A: Long-term frequent medium-load operation causes wear of internal gears and bearings of the pilot pump, increased internal leakage and decreased pilot pressure, resulting in insensitive main pump variable adjustment and weak hydraulic actions. Replacing the aging HVP116 pilot pump can restore original control performance.
Q3: How to maintain HVP116 pilot pump daily?
A: Keep hydraulic oil clean, replace hydraulic oil and filter elements regularly to prevent hard impurities from wearing precision gear components. Regularly check the pump body for oil leakage and abnormal noise to ensure stable pilot pressure output and normal main pump variable operation.
Q4: How to extend the service life of HVP116 pilot pump?
A: Avoid long-term continuous overload operation and frequent sudden load impact, maintain the cleanliness of the hydraulic system, reduce internal component wear and fatigue loss, and effectively extend the service life of the pilot pump.
