Embodiment 1

[0025] According to an embodiment of the present invention, an embodiment of a control method for a direct-fired evaporator of a liquid nitrogen pump truck is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a set of computer executable instructions, for example. and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

[0026] figure 1 It is a flow chart of a control method for a direct-fired evaporator of a liquid nitrogen pump truck according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0027] Step S102, obtaining the instantaneous flow of liquid nitrogen in the evaporator to be controlled;

[0028] Step S104, determining the instantaneous maximum output power of the evaporator to be controlled based on the instantaneous flow;

[0029] Step...

Abstract

The invention provides a control method and system for a direct-fired evaporator of a liquid nitrogen pump vehicle, relating to the technical field of equipment control, including: obtaining the instantaneous flow rate of liquid nitrogen in the evaporator to be controlled; based on the instantaneous flow rate, determining the evaporation rate to be controlled The instantaneous maximum output power of the evaporator; based on the instantaneous maximum output power, determine the number of working cylinders in the evaporator to be controlled; send control instructions to the evaporator to be controlled based on the number of working cylinders, so that the evaporator to be controlled The number of cylinders is randomly and symmetrically opened to work, which solves the technical problems of unbalanced use of each cylinder of the evaporator and dry burning without liquid nitrogen in the existing control method of the direct-fired evaporator of the nitrogen pump vehicle.

Description

technical field [0001] The invention relates to the technical field of equipment control, in particular to a control method and system for a direct-fired evaporator of a liquid nitrogen pump truck. Background technique [0002] For the direct-fired evaporator of the liquid nitrogen pump truck, the current mainstream control method is to use the original imported control system or the self-developed control system. The control methods of these two control systems are based on how to realize the temperature control of the direct-fired evaporator Accuracy and rapidity have not been further studied in combination with the application environment of the direct-fired evaporator. When the evaporator is applied to a liquid nitrogen pump, dry burning, uneven use of each cylinder block and damage to a single combustion cylinder are prone to occur. Problems such as failure operation cannot be carried out. [0003] For the above problems, no effective solutions have been proposed yet. ...
