Problems solved by technology

[0003] However, the existing speed measurement method uses a sensor to detect the speed of the hydraulic motor, and the sensor is installed together with the hydraulic motor. Since the hydraulic motor is installed in the pump casing of the hydraulic submersible pump, the installation of the sensor is very inconvenient

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] figure 1 It is a flow chart of a method for measuring the rotational speed of a hydraulic submersible pump provided by an embodiment of the present invention. Such as figure 1 As shown, the speed measurement method can be controlled by the host computer, including:

[0034] Step S1: Obtain the return oil flow rate and return hydraulic oil temperature of the hydraulic motor of the hydraulic submersible pump.

[0035] Wherein, when the hydraulic motor is working, a hydraulic pump is usually provided to deliver oil to the hydraulic motor. Therefore, the hydraulic motor has an oil inlet connected to the oil inlet pipeline and an oil outlet connected to the oil outlet pipeline. The oil return flow is the instantaneous oil flow val...

Abstract

The invention discloses a rotation speed measuring method and device of a hydraulic immersed pump and a hydraulic control system, and belongs to the technical field of ship liquid cargo loading and unloading. The rotation speed measuring method of the hydraulic immersed pump comprises the steps that the return oil flow and return oil hydraulic oil temperature of a hydraulic motor of the hydraulicimmersed pump are obtained; a flow value of the hydraulic motor is determined according to the return oil flow and the return oil hydraulic oil temperature; and the rotation speed of the hydraulic immersed pump is determined according to the flow value of the hydraulic motor. According to the rotation speed measuring method and device of the hydraulic immersed pump and the hydraulic control system, the rotation speed of the hydraulic immersed pump can be conveniently measured.

Description

technical field [0001] The invention relates to the technical field of ship liquid cargo loading and unloading, in particular to a method for measuring the rotational speed of a hydraulic submersible pump, a measuring device and a hydraulic control system. Background technique [0002] The hydraulic submersible pump is the pumping equipment used on the ship to transfer and transport the liquid cargo in the liquid cargo tank. Before the hydraulic submersible pump leaves the factory, a speed measurement test is usually required to test and evaluate the state performance of the hydraulic submersible pump. The hydraulic submersible pump is usually driven by a hydraulic motor, so the rotational speed of the hydraulic submersible pump can be obtained by measuring the rotational speed of the hydraulic motor. Sensors are currently used to detect the rotational speed of hydraulic motors. [0003] However, the existing rotational speed measurement method uses a sensor to detect the ...
