Problems solved by technology

[0005] The pressure transmitter dedicated to water pumps has always been installed by installing the sensor into the base. No buffer device is added to the diaphragm, and a retaining ring is often used to position the sensor in some transmitters. The safety factor is low. In the case of overload, it is easy to cause diaphragm breakdown and sensor positioning failure

Abstract

The invention relates to a special pressure transmitter for a water pump. The special pressure transmitter for the water pump comprises a base, a buffering sheet, foam cotton, a steel wire, an O-shaped seal ring, a sensor, a shell, a circuit board, a silicone wire, a Hirschmann joint, an air guide tube and an insulation sleeve, wherein a groove used for accommodating the O-shaped seal ring is formed in the outer circle of the sensor; the O-shaped seal ring is clamped with the sensor via the groove; a metal tube is arranged at the top of the sensor; the air guide tube is in inserted connection with the metal tube; a cavity with an open top is formed in the base; the sensor is arranged inside the cavity; the buffering sheet is arranged between the bottom of the cavity of the base and the bottom of the sensor; the foam cotton is arranged between the buffering sheet and the bottom of the sensor; the buffering sheet is clamped with the foam cotton via the steel wire; the circuit board is fixedly arranged in the insulation sleeve; the insulation sleeve is fixedly arranged in the shell; the circuit board is connected to the Hirschmann joint via the silicone wire; the top of the base is connected to one end of the shell; the other end of the shell is connected to the Hirschmann joint.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a pressure transmitter, in particular to a special pressure transmitter for water pumps. Background technique [0002] Pressure transmitter is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, and ships. , machine tools, pipelines and many other industries. [0003] Pressure transmitters mainly include capacitive pressure transmitters, diffused silicon pressure transmitters, ceramic pressure transmitters, strain gauge pressure transmitters, etc. Pressure transmitters can be divided into general pressure transmitters (0.001MPa~35MPa), differential pressure transmitters (0~1.5kPa) and negative pressure transmitters according to...
