Problems solved by technology

[0002] The gear pump is the power element of the hydraulic system, fuel system, etc. During the working process of the gear pump, due to the relative movement and friction of the gear end face, the gear end face will be worn for a long time, the gap between the gear end face will increase, and the leakage of the gear end face gap will increase accordingly. If the gear pump is large, the outlet flow rate of the gear pump will decrease, and the actual flow rate of the existing gear pump cannot be detected and calibrated in real time during the working process, so the flow rate of the gear pump will not meet the service requirements after long-term operation, and the service life will be low

Embodiment 1

[0033] like Figure 1-11 Show, a traffic intelligent calibration gear pump, including the gear pump pump body, the gear pump body is opened with main oil port 5, main outlet outlet 6, motor component on the gear pump body 1. Gear pump component 2. Control valve component 3; the control valve component includes the control valve shell installed on the gear pump. The control valve shell is installed in the main valve to change the flow of the liquid in the gear pump. , The first oil outlet, a throttle drool, the first oil outlet, and the throttling droosure as the oil end of the two positions of the main valve, respectively. The oil outlet is connected with the main oil port; the control valve shell is also installed in the pilot valve 4 used to control the main valve core. The valve core 11 is connected to the driver source 18, and the pressure sensor is connected to the drive source 18 by the controller. Among them, the main valve and the pilot valve are both four -bodium four -way...

Abstract

The invention discloses an intelligent flow calibration gear pump and relates to the technical field of gear pumps, the intelligent flow calibration gear pump comprises a gear pump body, a main oil inlet and a main oil outlet are formed in the gear pump body, a main valve for changing the flow direction of liquid in the gear pump is arranged in the gear pump body, and a first oil inlet, a first oil outlet and a throttling opening are formed in the main valve; the first oil outlet and the throttling opening serve as oil outlet ends of two positions of the main valve respectively, a pilot valve is further arranged in the gear pump body, a pressure sensor used for detecting the pressure of liquid in the pump is further arranged on the gear pump body, a valve element of the pilot valve is connected with a driving motor, and the pressure sensor is connected with a driver. A direction control valve, a pressure sensor and the like are integrally designed with a gear pump, and the flow is calibrated through the corresponding relation between pressure and the flow. Reversing of the main valve is controlled through the pilot valve, reversing force needed by the valve element of the main valve under the large-flow condition can be met, and meanwhile the whole pump is compact in structure, small in size and light in weight.

Description

Technical field [0001] The present invention is a technology field related to gear pumps. More specifically, it is specially involved in a traffic intelligent calibration gear pump. Background technique [0002] Gear pump is a dynamic element of hydraulic and fuel systems. During the working process of gear pumps, due to the relative movement and friction of the gear end surface, it will cause the gear end surface to wear. Large, the outlet flow of the gear pump is reduced, and the existing gear pump cannot conduct real -time detection and calibration of its actual traffic during the working process. After the long -term work of the secondary gear pump will not meet the use requirements, and the life span will be low. Invention content [0003] The embodiment of this application provides a traffic intelligent calibration gear pump to solve the problems existing in existing technologies, and the direction control valve, pressure sensor and other integrated design with the gear pu...
