Abstract
The utility model discloses a kind of temperature sensor protecting equipment, including netted halter, rubber closing piece, briquetting, clamp nut；Rubber closing piece is filled in netted halter port, and briquetting is arranged at the top of rubber closing piece, and clamp nut is tightened on netted halter port；The gauge head of temperature sensor can pass sequentially through clamp nut, briquetting, the hole in the middle of rubber closing piece and insert in netted halter; tighten clamp nut; clamp nut extruding briquetting deforms rubber closing piece, temperature sensor and temperature sensor protecting equipment is fixed spacing.Air can pass through gauge head by the halter of network structure, and such sensor can just measure the temperature for obtaining engine charge.
Description
Technical field
The utility model belongs to engine rig test field, and in particular to a kind of intake air temperature sensor protection device.
Background technology
The number that air capacity in cylinder is actually entered in engine pedestal rating test is closely related with temperature, adopts at present
Collect cylinder temperature using sensor, method is inserted, the position of temperature sensor gauge head is closer to inlet valve, and measurement cylinder temperature is more accurate
Really.It is big using conventional PT100 sensors rigidity, after the entrance air intake duct of manifold outer wall straight, the positional distance of gauge head
Valve port is distant, and the error of measurement is larger；It can make gauge head as far as possible using a kind of temperature sensor of elongated Low rigidity
Close to inlet valve port, but be due to that rigidity is low, gauge head is easily contacted with air intake duct inwall, and measurement result is inaccurate, and
Due to factor wear out failures such as vibrations in engine operation process.
Utility model content
The purpose of this utility model is to provide a kind of intake air temperature sensor protection device, can guarantee that measurement temperature is accurate,
Simple in construction, easy to install, highly versatile may be reused.
Technical solutions of the utility model are as follows：
A kind of intake air temperature sensor protection device, including netted halter, rubber closing piece, briquetting, clamp nut；Rubber is locked
Block is filled in netted halter port, and briquetting is arranged at the top of rubber closing piece, and clamp nut is tightened on netted halter port；Temperature
The gauge head of sensor can pass sequentially through clamp nut, briquetting, the hole in the middle of rubber closing piece and insert in netted halter, tighten compression spiral shell
Mother, clamp nut extruding briquetting deforms rubber closing piece, and limit is fixed to temperature sensor and temperature sensor protecting equipment
Position.
The utility model has the halter of a network structure, and temperature sensor is inserted by the hole of one end, makes TEMP
The probe location of device is located in the middle of halter, and air can pass through gauge head by the halter of network structure, and such sensor just can be with
Measurement obtains the temperature of engine charge.On the one hand the utility model protects gauge head not contacted with air intake duct inwall, while also preventing
The damage of temperature sensor gauge head is stopped.

Embodiment
1 describe specific embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
A kind of temperature sensor protecting equipment, including：1st, netted halter, 2, rubber closing piece, 3, briquetting, 4, clamp nut.
Assembly method：The gauge head of intake air temperature sensor passes sequentially through clamp nut 4, briquetting 3, the hole insertion net of the centre of rubber closing piece 2
Shape halter 1, make gauge head position be in netted halter 1 appropriate location when, rubber closing piece 2 is filled in the netted port of halter 1, pressure
Block 3 is arranged on the top of rubber closing piece 2, and clamp nut 4 is tightened on the netted port of halter 1.Tighten clamp nut 4, clamp nut 4
Extruding briquetting 3 deforms rubber closing piece 2, pins intake air temperature sensor and intake air temperature sensor protection device, solid to both
Fixing limit.
Below in conjunction with the accompanying drawings 2 explanation under concrete application of the present utility model：
The intake air temperature sensor protection device for assembling completion is stretched into by inlet manifold along air intake duct, works as TEMP
Device protection device pulls back 5mm when touching inlet valve 6, then fix the nut of outside.Inlet valve temperature is passed
Sensor installation.
