3 important sensors for cars(Update)

As a daily travel tool for people, cars have a complicated structure, and there are hundreds of sensors alone, and these sensors are needed to start and run cars and drive safely. Among the more than 100 sensors in automobiles, we need to understand these three sensors.

1. Odometer sensor

Odometer sensors generally use Hall and photoelectric methods to detect signals. Their purpose is to use mileage to record and analyze the driving speed and mileage of the car.

Although the odometer sensor does not seem to have any practical effect, when it is abnormal, it cannot display the car loss signal, the driver cannot control the speed of the car, and it is easy to overspeed in the speed limit section. What you are waiting for is a large number of fines and hidden life Safe and dangerous. Some models will also be affected after the odometer sensor fails to work.

2. Water temperature sensor

The water temperature sensor is a sensor that exists inside the engine and belongs to a semiconductor thermistor. The lower the temperature, the greater the resistance. The electronic control unit inside the car will be used as a correction standard for fuel injection and ignition timing according to the change of the water temperature sensor.

If there is a problem with the water temperature sensor, it is easy to cause the engine temperature to rise without knowing, and the water temperature cannot be adjusted in time, causing damage to the engine.

3. Collision sensor

Collision sensors are also called airbag sensors, and can be divided into trigger collision sensors and guard collision sensors according to their uses. Triggered collision type is used to detect the acceleration change during collision, as the trigger type of the airbag; the protective collision type is connected in series with the triggered collision type to prevent the airbag from accidentally exploding.

For the collision sensor, its function is self-evident, it needs regular inspection to avoid problems at the critical moment and threaten life safety.

4 technical measures to reduce the deologformation of aluminum fabrication

Aluminum products need to go through different processing methods before they can adapt to various working environments and provide better working performance. However, during the processing of aluminum products, due to errors in the fabrication flow or improper personal technical operation, it is easy to cause deformation of aluminum processing. Jiang Yin Ming Ding Aluminum Products Co., Ltd. provides you with four technological measures to reduce the deformation of aluminum fabrication.

1. Reduce the internal stress of the blank

Using natural or artificial aging and vibration treatment can partially eliminate the internal stress of the blank, and can also be processed in advance. When processing large blanks, because there are many processed parts, it is also easy to deform. This requires pre-processing to remove excess parts and reduce the probability of deformation. During the placement time after pre-processing, the internal stress can also be released.

2. Improve the cutting ability of the tool

The material and geometric parameters of the tool have an important influence on the cutting force and cutting heat of the tool. Choosing the right tool can reduce the chance of machining deformation of the part.

To improve the cutting ability of the tool, these two aspects need to be achieved: ① reasonable selection of the geometric parameters of the tool; ② improvement of the tool structure

3. Improve the clamping method of the workpiece

For thin-wall aluminum parts with poor rigidity, the method of clamping can be used to reduce the possibility of deformation:

① For thin-walled bushing parts, the axial end surface compression method with better rigidity should be used, and the three-jaw self-centering chuck or spring chuck cannot be directly used to clamp in the radial direction.

②When processing thin-walled and thin-plate aluminum parts, it is best to use vacuum suction cups, and then use a smaller amount of cutting to process.

4. Reasonably arrange the process

Before processing aluminum, it is necessary to evaluate the aluminum parts and then decide how to arrange the processing procedures.

Must see！3 important parameters of cooling fan！

We can often find some parameters written on it when purchasing a cooling fan, such as: CFM, CMM and RPM. What are these three parameters that represent the performance of the cooling fan? What does it mean? Suzhou Santian Precision Mould Co., Ltd. will answer the important parameters of these three cooling fans for you.

CFM, CMM:

These two parameters are the air volume units of the cooling fan, but they are expressed differently. The so-called air volume refers to the volume of air passing through the cross section of the fan outlet per unit time. If the unit is cubic feet, the parameter is expressed in CFM. If the unit is cubic meters, the parameter display is CMM. The air volume of the cooling fan depends on the height of the custom and the size of the over-wind area.

Calculation formula: air volume = average wind speed × overwind area

Cooling fans

RPM:

This parameter refers to the speed unit of the cooling fan. The so-called rotational speed refers to the number of revolutions of the fan blade in a unit time. Speed is one of the fundamental determinants of the performance indicators of the fan, which basically depends on the performance of the motor used by the fan. Some fans have a high speed, but the noise is also greater. The higher the RPM, the stronger the fan performance, and the greater the friction, vibration, and noise. The bearing losses are also more serious, and the motor consumes more power.

The above are the three important parameters of the cooling fan. When purchasing the cooling fan, please pay close attention to these three parameters to provide you with better help in choosing the cooling fan!

Solar framework price, 2020 new information

The solar frame can well protect the solar panel and extend the service life of the solar panel. The solar frames we usually see on the market are mainly divided into three materials: stainless steel, aluminum products and plastics. Under the influence of practical life and cost, we can be sure of the fact that aluminum solar frames are the best of!

Although the solar aluminum frame is lower in cost than the solar stainless steel frame, the price is not cheap. This is mainly due to the long labor inspection time and high technical requirements in the production process of the aluminum frame.

1. Due to the harsh working environment, it is required that the solar aluminum frame can withstand the backlog of snowstorm and the corrosion of other substances, which requires the solar aluminum frame to have extremely high quality. Not only the requirements for product raw materials are high, but also the technical processing of aluminum frames has higher requirements. For example, the thickness of the oxide film of the solar aluminum frame is more than 5μ thicker than the ordinary industrial aluminum profile frame

2. After the solar cell is used for a long time, the phenomenon of expansion is easy to occur, which easily makes the aluminum frame burst. Therefore, in order to better protect the solar cell, prevent it from expanding, and fix its shape, the aluminum frame needs to be accurately and seamlessly connected, so each aluminum strip needs to be manually inspected.

The above two points are the most important factors for the high price of solar aluminum frames. The cost of plastic frames is lower than the cost of aluminum frames, but it is extremely easy to damage solar panels and bring greater losses.
