description

PSVD2-27E hydraulic pump spare parts adopt targeted medium-load reinforcement optimization for 10–12 ton excavator working conditions. Core friction pair components adopt high-rigidity enhanced alloy steel matrix + high-density uniform wear-resistant copper alloy composite structure, balancing high torque output stability and long-cycle wear resistance, fully adapting to high-frequency medium-load cyclic operation of medium-small engineering machinery. The cylinder block undergoes integral precision heat treatment and multi-times micro stress relief to completely eliminate processing residual stress and operational fatigue stress, matched with ultra-precision mirror lapping to form ultra-stable micron-level clearance fit with the valve plate, effectively restraining progressive internal leakage caused by long-term medium-pressure continuous operation. The upgraded piston-shoe assembly adopts deepened high-flow lubrication grooves and enhanced anti-sticking friction structure, reducing medium-load cyclic friction loss during frequent commutation and climbing operation, maintaining stable high-torque output and smooth low-speed operation without stuttering or power attenuation. The reinforced valve plate and retainer plate optimize contact stress uniform distribution, comprehensively improving medium-pressure impact resistance and structural fatigue resistance, completely solving stubborn faults such as medium-load crawling, walking deviation and intermittent jitter of 10–12 ton excavators.

advantage

OEM Micron Precision, 100% Lossless Interchangeability: All PSVD2-27E spare parts are manufactured strictly in accordance with OEM micron-level dimensional, flatness and tolerance standards. No on-site grinding or modification is required, with ultra-high fitting accuracy, fully matching the assembly structure and medium-load operating parameters of original 10–12 ton excavator travel motors.
Medium-Load Reinforced Optimization, High Torque Stable Output: Core friction pairs adopt multi-cycle stress relief and alloy reinforcement technology, specially optimized for long-term medium-load high-frequency operation of 10–12 ton excavators. It effectively solves low-speed stuttering and insufficient climbing power, maintaining continuous and stable high-torque output without performance attenuation.
High Cost-Performance, Reduce Medium-Load Construction Downtime Loss: Support flexible single-piece replacement for local moderate wear and full kit replacement for overall aging. Avoid expensive integral motor replacement, greatly reducing daily operation and maintenance costs and large-volume construction shutdown losses of 10–12 ton medium-small excavators.
Multi-Process Strict Factory Inspection, Stable Batch Quality: Each batch of spare parts undergoes precision dimensional verification, flatness testing, hardness sampling and medium-pressure cycle impact tests to ensure uniform batch quality, guaranteeing stable and durable medium-load operating performance after equipment repair.
Excellent Medium-Pressure Durability, Strong Working Condition Adaptability: Exclusive medium-load grade material formula adapts to long-term medium-pressure continuous operation and frequent load switching, resisting medium-level oil scouring and pressure fluctuation impact, effectively delaying component aging and extending medium-load travel motor service life.

FAQ

Q1: What typical medium-load faults can PSVD2-27E spare parts solve?
A: It thoroughly fixes common medium-load faults of PSVD2-27E medium-load travel motor, including progressive medium internal leakage, insufficient medium-load climbing torque, obvious low-speed stuttering, insensitive hydraulic linkage response, bilateral walking speed deviation, medium-load walking jitter, minor abnormal operating noise and persistent medium-pressure oil seepage.
Q2: What equipment is PSVD2-27E suitable for?
A: Mainly applicable to 10–12 ton various brands of medium-small excavators, widely used in municipal large-volume earthwork, road infrastructure construction, stone yard material handling and medium-load cyclic construction scenarios, perfectly matching original PSVD2-27E travel motor assembly and system supporting parameters.
Q3: How to choose single parts or full overhaul kit?
A: For motors with short service life and only local moderate wear, select single-piece targeted replacement; for motors with long-term frequent medium-load operation, obvious torque attenuation and overall component aging, full rotating group kit replacement is recommended to restore original medium-load high-torque performance.
Q4: What are the key overhaul points for PSVD2-27E motor?
A: Thoroughly clean internal medium-load wear powder and micro impurities, replace all aging medium-pressure anti-aging seals, strictly control medium-load friction pair assembly clearance and flatness fitting, and conduct medium-load walking test and precise debugging after assembly to ensure bilateral speed synchronization and stable high-torque output.
Q5: How to extend PSVD2-27E travel motor service life?
A: Keep hydraulic oil highly clean and replace filter elements regularly; avoid long-term continuous overload and over-pressure operation; control system oil temperature within normal range to prevent oil deterioration and seal premature aging under long-term medium-load working conditions.
