Abstract
The utility model provides a pressure-controllable hydraulic tapping machine, which comprises a hydraulic tapping machine body, wherein an impact oil inlet and a rotary oil inlet are arranged on the hydraulic tapping machine body; the first pressure control device is communicated with an impact oil path in the hydraulic tapping machine body; the rotary oil inlet is communicated with a second pressure control device used for controlling the rotary oil pressure, and the second pressure control device is communicated with a rotary oil path inside the hydraulic tapping machine body. And the oil inlet pressure is ensured not to be higher than the design requirement.
Description
Technical Field
The utility model relates to a stokehold equipment field, a controllable hydraulic pressure tapping machine of pressure very much.
Background
The blast furnace iron making process needs to frequently carry out iron notch opening operation, the core equipment of the iron notch opening is a hydraulic tapping machine, the performance of the hydraulic tapping machine directly influences the blast furnace production, and the hydraulic tapping machine is one of key equipment for the production in front of the furnace. The hydraulic tapping machine must be used strictly according to the design parameters to ensure the performance and service life of the hydraulic tapping machine. The oil feed pressure of a hydraulic tapping machine is one of the key factors that affect its service life.
The oil inlet pressure of the existing hydraulic tapping machine is set during installation and debugging, a user frequently increases the oil inlet pressure in the using process, a pressure regulating valve for the tapping machine is not designed in some hydraulic systems, the oil inlet pressure of the tapping machine is the same as the pressure of the system and is far higher than the pressure required by the normal use of the hydraulic tapping machine, and the service life of the hydraulic tapping machine is influenced, so that the development of the hydraulic tapping machine capable of controlling the inlet pressure is necessary.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a controllable hydraulic pressure tapping machine of pressure guarantees that oil feed pressure is not higher than the design requirement.
In order to realize the technical characteristics, the purpose of the utility model is realized as follows: a pressure-controllable hydraulic tapping machine comprises a hydraulic tapping machine body, wherein an impact oil inlet and a rotary oil inlet are formed in the hydraulic tapping machine body; the first pressure control device is communicated with an impact oil path in the hydraulic tapping machine body; the rotary oil inlet is communicated with a second pressure control device used for controlling the rotary oil pressure, and the second pressure control device is communicated with a rotary oil path inside the hydraulic tapping machine body.
And the first pressure control device and the second pressure control device both adopt pressure limiting valves.
The utility model discloses there is following beneficial effect:
the utility model discloses in through installing corresponding first pressure control device and the second pressure control device at two different import positions of hydraulic pressure tapping machine body and then control the regulation to the oil pressure that enters into hydraulic pressure tapping machine body inside, make it keep at the oil pressure of settlement, prevent the too high and damage to the hydraulic pressure tapping machine body that leads to of oil pressure.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention.
In the figure: the hydraulic tapping machine comprises a first pressure control device 1, a hydraulic tapping machine body 2, an impact oil inlet 3, a rotary oil inlet 4 and a second pressure control device 5.
Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 1, a pressure-controllable hydraulic tapping machine comprises a hydraulic tapping machine body 2, wherein an impact oil inlet 3 and a rotary oil inlet 4 are arranged on the hydraulic tapping machine body 2; the impact oil inlet 3 is connected with a first pressure control device 1 for controlling impact oil pressure, and the first pressure control device 1 is communicated with an impact oil path inside the hydraulic tapping machine body 2; the rotary oil inlet 4 is communicated with a second pressure control device 5 for controlling the rotary oil pressure, and the second pressure control device 5 is communicated with a rotary oil path inside the hydraulic tapping machine body 2. Through adopting foretell hydraulic pressure tapping machine, install corresponding first pressure control device 1 and second pressure control device 5 and then control the oil pressure on original hydraulic pressure tapping machine body 2, guarantee that oil feed pressure is not higher than the design pressure, and then play fine guard action to hydraulic pressure tapping machine body 2.
Further, both the first pressure control device 1 and the second pressure control device 5 employ pressure limiting valves.
The working process of the utility model is as follows:
1. the pressure oil enters the first pressure control device 1 and the second pressure control device 5 through the impingement oil inlet or the swivel oil inlet.
2. The first pressure control device 1 and the second pressure control device 5 control the pressure input to the hydraulic tapping machine body 2 within the design required pressure.
3. The hydraulic tapping machine body 2 operates at normal pressure.
