Self-reminding mechanical pressure gauge for hydraulic pump station

Abstract

The invention discloses a self-reminding mechanical pressure gauge for a hydraulic pump station. The self-reminding mechanical pressure gauge comprises a mechanical pressure gauge body, wherein the lower end of the mechanical pressure gauge body is fixedly connected with a connecting pipe, one side wall of the mechanical pressure gauge body is connected with a maintenance screw, the mechanical pressure gauge body is connected with a pointer shaft, a pointer is fixedly connected onto the pointer shaft, one end, far away from the pointer shaft, of the pointer is provided with a sensing end, andthe mechanical pressure gauge body is fixedly connected with a dial corresponding to the pointer; the self-reminding mechanical pressure gauge for the hydraulic pump station has the characteristics ofhigh mechanical strength, high accuracy, convenience in production and the like of the mechanical pressure gauge, and has the characteristic of convenience in reading of an electronic pressure gauge.When the pressure gauge is abnormal, reminding can be carried out actively, staff is reminded to respond to the abnormity in time, damage to a hydraulic pump is not easy to occur, meanwhile, remote monitoring and data recording can be carried out, and the self-reminding mechanical pressure gauge is convenient for management personnel to manage.

Description

technical field [0001] The invention relates to the technical field of pressure gauges for hydraulic pump stations, in particular to a self-reminder mechanical pressure gauge for hydraulic pump stations. Background technique [0002] The hydraulic pump station is a hydraulic source device composed of a hydraulic pump, a driving motor, a fuel tank, a pressure gauge, a directional valve, a throttle valve, and a relief valve, or a hydraulic device including a control valve. Supply oil according to the flow direction, pressure and flow required by the driving device. It is suitable for all kinds of machinery where the driving device and the hydraulic station are separated. Connect the hydraulic station and the driving device (oil cylinder or motor) with oil pipes, and the hydraulic system can realize various regulations. Actions. [0003] Among them, pressure gauges are divided into mechanical pressure gauges and electronic pressure gauges. Mechanical pressure gauges refer to i...

Problems solved by technology

Although electronic pressure gauges can automatically generate readings and are convenient for reading, their accuracy and stability are not good, especially for hydraulic pump stations.

[0004] The structure of the mechanical pressure gauge in the prior art includes a pointer, a dial and a glass panel. By judging the position indicated by the pointer on the dial, the numerical value of the pressure is determined. Although the mechanical pressure gauge has high mechanical strength, high accuracy, and is easy to produce and other characteristics, but it needs to be actively observed to judge its logarithm. When the pressure indication value is abnormal, it cannot be actively reminded. expand
