Problems solved by technology

[0002] When the high-pressure plunger pump is started, it rotates with the input shaft, and the pump begins to generate pressure. At present, the driving power source of the commonly used pump is a motor or a gasoline engine. The high-pressure medium in the pump will directly increase the input torque of the pump, which affects the power of the motor. In other words, it is necessary to increase the starting current of the motor, and the increase of the starting current may cause the motor to burn out or the fuse to blow out, etc.; for gasoline engine power, if the power has not reached the no-load idle speed, if the load is applied, the power will be overloaded and stop

Embodiment Construction

[0019] The present invention will be further described below with specific embodiment, see Figure 1-3 :

[0020] The high-pressure plunger pump pressure regulating system with easy-start function is composed of a pressure regulating system and an easy-start valve, and a set pressure can be closed between the water inlet area 14 and the return water area 9 of the pressure regulating system. Easy to start valve.

[0021] The above-mentioned easy-to-start valve is: on the pipeline connecting the water inlet area 14 and the return water area 9 of the pressure regulating system, the elastic force of the spring 10 of the easy-to-start valve makes the valve core 12 far away from the position where the pipeline of the valve seat 11 is conducted.

[0022] The above-mentioned spool 12 is a steel ball.

[0023] The pipeline connecting the water inlet area 14 and the return water area 9 of the above-mentioned pressure regulating system: it is a process hole added between the water inle...

Abstract

The invention belongs to the technical field of high-pressure plunger pumps, and particularly refers to a high-pressure plunger pump pressure regulation system with easy-start function, which is composed of a pressure regulation system and an easy-start valve. There is an easy-start valve with a set pressure that can be closed between the water areas. This invention can prevent the motor from being stuck when starting, making it easy to start, greatly improving the convenience of pump operation and use, and has very strong creativity and practicability , Suitable for all types of high-pressure plunger pumps.

Description

Technical field: [0001] The invention belongs to the technical field of high-pressure plunger pumps, in particular to a high-pressure plunger pump pressure regulating system with an easy-to-start function. Background technique: [0002] When the high-pressure plunger pump is started, it rotates with the input shaft, and the pump begins to generate pressure. At present, the driving power source of the commonly used pump is a motor or a gasoline engine. The high-pressure medium in the pump will directly increase the input torque of the pump, which affects the power of the motor. In other words, it is necessary to increase the starting current of the motor. An increase in the starting current may cause the motor to burn out or the fuse to blow out, etc.; for gasoline engine power, if the power has not reached the no-load idle speed, the load will be added, and the power will be overloaded and stop. The high-pressure plunger pump pressure regulating system is equipped with an ea...
