description

In daily micro-construction, municipal trimming and garden engineering scenarios, the PSVD2-17E motor endures long-term frequent flexible start-stop, repeated low-intensity vibration and long-duration low-temperature oil scouring, which easily causes micro friction pair wear, subtle surface scratches and slow volumetric efficiency attenuation, resulting in typical mini-machine problems such as low-speed crawling, insensitive hydraulic linkage, asynchronous left-right walking speed and slight running jitter. PSVD2-17E hydraulic pump spare parts adopt targeted lightweight optimization for mini-excavator working conditions. Core friction pair components adopt high-precision compact alloy steel matrix + fine uniform wear-resistant copper alloy composite structure, balancing flexible response and long-term wear resistance, fully adapting to frequent cyclic flexible operation of small construction machinery. The cylinder block undergoes precise integral heat treatment and micro stress relief to eliminate tiny processing residual stress, matched with ultra-precision mirror lapping to form stable micron-level clearance fit with the valve plate, effectively restraining slow internal leakage growth caused by long-term low-pressure continuous operation.

FAQ

Q1: What typical mini-machine faults can PSVD2-17E spare parts solve?
A: It thoroughly fixes common light-duty faults of PSVD2-17E mini travel motor, including slow internal leakage growth, low-speed crawling and stuttering, insensitive walking response, unilateral speed asynchronous, subtle running jitter, minor abnormal noise and long-term micro oil seepage.
Q2: What equipment is PSVD2-17E suitable for?
A: Mainly applicable to 6–8 ton various brands of mini excavators, widely used in urban municipal micro-renovation, garden construction, indoor demolition and site leveling scenarios, perfectly matching original PSVD2-17E mini travel motor assembly and system parameters.
Q3: How to choose single parts or full overhaul kit?
A: For motors with short service life and only local slight wear, select single-piece targeted replacement; for motors with long-term frequent flexible operation, obvious response lag and overall component aging, full rotating group kit replacement is recommended to restore original low-speed stable performance.
Q4: What are the key overhaul points for PSVD2-17E motor?
A: Thoroughly clean internal micro wear powder and tiny impurities, replace all aging low-pressure anti-aging seals, strictly control micro friction pair assembly clearance and flatness fitting, and conduct low-load walking test and fine debugging after assembly to ensure synchronous left and right speed and stable flexible output.
Q5: How to extend PSVD2-17E travel motor service life?
A: Keep hydraulic oil clean and replace filter elements regularly; avoid long-term continuous overload operation; maintain normal system oil temperature to prevent oil deterioration and premature seal aging in low-pressure working environments.
