Numerous industry such as lathe, pipeline.
Pressure transmitter mainly has capacitance pressure transmitter and diffused silicon pressure transmitter, ceramic pressure transmitter, answers
Variant pressure transmitter etc..Pressure transmitter according to pressure measurement scope be divided into general pressure transmitter (0.001MPa～35MPa),
Differential pressure transmitter (0～1.5kPa) and negative pressure transmitter three kinds.
The Main Function of pressure transmitter passes to electronic equipment pressure signal, and then in its principle of Computer display pressure
It is substantially: and the mechanical signal of this for hydraulic pressure pressure is transformed into electric current (4-20mA) such electronic signal pressure and voltage or electricity
Stream size is linear, usually proportional relation.
The method that water pump special pressure transmitter has been used up loading in pedestal by sensor is installed, at diaphragm position
Not adding any buffer unit, and often use back-up ring to carry out alignment sensor in part transmitter, safety coefficient is low, at pressure
In the case of overload, it is susceptible to diaphragm and punctures the situation lost efficacy with sensor location.

Detailed description of the invention:
Below the detailed description of the invention of the present invention is described in detail.
As it is shown in figure 1, water pump special pressure transmitter, including pedestal 1, buffer substrate tablet 3, foam 4, steel wire 5, O RunddichtringO
6, sensor 7, housing 8, circuit board 9, silica gel line 10, Hirschmann joint 11, airway 12 and insulating sleeve 13,
The cylindrical of sensor 7 is provided with the groove accommodating O RunddichtringO 6, and O RunddichtringO 6 and sensor 7 are by this groove card
Connect,
The top of sensor 7 is provided with metal tube, airway 12 and this metal tube grafting,
Pedestal 1 is provided with the cavity that top is opened wide, and sensor 7 is located in this cavity, the cavity bottom of pedestal 1 and sensor 7
Bottom between be provided with buffer substrate tablet 3, between the bottom of buffer substrate tablet 3 and sensor 7, be provided with foam 4, buffer substrate tablet 3 leads to foam 4
Cross steel wire 5 clamping,
Circuit board 9 is fixedly arranged in insulating sleeve 13 by the way of embedding silicone rubber, and insulating sleeve 13 passes through interference fit
Mode is fixedly arranged in housing 8, and circuit board 9 is connected by silica gel line 10 with Hirschmann joint 11,
The top of pedestal 1 is threaded connection with one end of housing 8, and the other end of housing 8 passes through with Hirschmann joint 11
Threaded.
Further, rectangular seal 2 also it is arranged with in the middle part of the lateral wall of pedestal 1.
Further, the bottom of pedestal 1 is provided with screw, and the internal diameter of this screw is 3mm.
The phenomenon in use easily causing diaphragm to damage in view of transmitter because of overvoltage and icing, has invented water pump
Special pressure transmitter, it is possible to solve the problems referred to above.
As it is shown in figure 1, when hydraulic pressure arrives at transmitter, add buffer substrate tablet 3, play cushioning effect, make current disperse, from respectively
Individual direction arrives sensor 7, and overvoltage thus can be avoided to cause diaphragm to puncture.And steel wire 5 can make foam 4 not with sensing
Device 7 contacts,
In the case of cold weather, measured medium (namely water) icing volumetric expansion, therefore add foam 4, at liquid
During icing volumetric expansion, compressing foam 4, so that diaphragm pressure experienced reduces, protection diaphragm is because being become by excessive pressure
Shape.
Sensor 7 uses housing 8 point of shoulder to position, and increases intensity, uses threaded, firmly between pedestal 1 and housing 8
Reliably, and add O RunddichtringO 6, play sealing function, it is ensured that the sealing of whole transmitter.
Use shaft end seal, add rectangular seal 2, seal when measuring reliable.
Whole transmitter uses standard component Hirschmann joint 11, adds the interchangeability of product.
Above embodiments of the present invention are elaborated.But the present invention is not limited to above-mentioned embodiment,
In the ken that art those of ordinary skill is possessed, it is also possible to do on the premise of without departing from present inventive concept
Go out various change.
