Rocket 1L03DE10RDouble stage combined gear pumpDetailed Explanation of Technical Parameters and Adaptation Scheme for Small and Medium sized Hydraulic Equipment

In the procurement and maintenance of small and medium-sized hydraulic equipment such as tractors, forklifts, and small loaders, selecting the right pump type is the key to ensuring stable system operation. The Roquet 1L03DE10R gear pump, as the core model of the L0 series, has become the preferred choice for this type of equipment due to its high pressure output of 275 bar, precise flow rate of 3 L/min, and standardized structure. This article will provide comprehensive references for equipment procurement managers and maintenance engineers from three aspects: technical parameters, industry pain point solutions, and application cases.

2、 How Roquet 1L03DE10R solves the core pain points of small and medium-sized hydraulic equipment

Small and medium-sized hydraulic equipment often faces three major pain points during operation: "unstable power", "difficult installation and adaptation", and "high maintenance costs". However, Roquet 1L03DE10R has solved them one by one through technical design:

1. Unstable power issueTraditional hydraulic pumps are prone to ± 10 bar fluctuations under 275 bar pressure due to unbalanced radial forces, resulting in tractor suspension jamming and forklift lifting shaking. Roquet 1L03DE10R adopts hydraulic balance design, optimizes gear tooth profile and sets balance groove, and controls pressure fluctuation within ± 5 bar to ensure smooth operation of the equipment. At the same time, the automatic lateral adjustment technology can automatically compensate for gear wear clearance (0.02-0.05mm), and even after 5000 hours of operation, the flow attenuation rate is only 3%, avoiding a decrease in power.

2. Difficulty in installation and adaptationDuring maintenance, the shaft type and front end cover specifications of the old pump body are not consistent, and the equipment base or pipeline needs to be modified. The E-shaft, 10 front end cover, and R-port of Roquet 1L03DE10R are all standardized designs, which can directly replace domestic or imported pump bodies of the same specifications (such as Rexroth and Parker models of the same level). The installation time is shortened from 8 hours to 2 hours, reducing equipment downtime losses.

3. The problem of high maintenance costsThe core components (pump shaft, castings) of Roquet 1L03DE10R are all independently produced by Roquet, and special spare parts kits (such as drive shaft kit, seal kit) are provided, so there is no need to replace the pump body as a whole during maintenance. Taking seal wear as an example, replacing Roquet's original seal only costs 500 yuan, far lower than the 3000 yuan cost of replacing a new pump.

3、 Roquet 1L03DE10R Typical Application Cases and Installation Suggestions

Case 1: Upgrading the hydraulic suspension system of a tractorThe Dongfanghong tractor at a certain agricultural machinery station has a raw liquid pressure pump pressure of only 200 bar, and the suspension lifting is stuck. After replacing Roquet 1L03DE10R, the continuous high pressure output at 275bar ensures smooth lifting and lowering of the suspension, and the low temperature adaptability at -20 ℃ solves the problem of difficult starting in winter in the north, increasing operational efficiency by 20%.

Case 2: Maintenance of forklift lifting mechanismThe Heli forklift in a certain logistics park had a pump that was unable to lift due to shaft wear. The E-shaft of Roquet 1L03DE10R is directly adapted to the motor coupling, and the R-port does not require pipeline replacement. After maintenance, the lifting speed was restored to 0.5m/s, which meets the design standards.

Installation recommendationsPriority should be given to using elastic couplings as the driving method to absorb radial/axial vibrations of 0.3-0.4mm and avoid damage to the pump body caused by motor vibrations; ② The diameter of the suction pipe should be ≥ 16mm to ensure a pressure drop of<0.3bar and prevent cavitation; ③ Before installation, it is necessary to check the cleanliness of the oil. If it does not meet the requirements of 19/16 (ISO 4406), the oil and filter element need to be replaced.

As the core model of the Spanish Roquet brand, 1L03DE10R has passed 99.9% factory testing, ensuring reliability. Whether it is the "cost performance balance" during equipment procurement or the "quick adaptation" during maintenance, they are both high-quality choices for small and medium-sized hydraulic systems.
