The benefits of measuring blood pressure at home

Regularly measuring blood pressure at home is an action that medical experts strongly encourage. Because not only is it good for people suffering from high blood pressure, but normal people also get many different benefits. Even though you may not have high blood pressure at the present time, you are at risk of developing this disease in the future. Measure blood pressure regularly every day to screen for disease as well as adjust your lifestyle and living habits to be healthy.

Here are some benefits of measuring blood pressure at home, including:

• Recognizing abnormal signs from blood pressure parameters and thereby detecting other related diseases such as kidney disease, diabetes, etc. early on will facilitate treatment.
• For hypertensive patients, measuring blood pressure is the best way to control the disease! Thanks to daily blood pressure records, your treating doctor can effectively provide a treatment regimen and methods to handle unexpected situations that may arise.
• Thanks to daily blood pressure measurement, patients can adjust their living habits and diet accordingly and control the situation. This is also the basis for them to know when they need to see a doctor.
• Measuring your blood pressure also helps you recognize when it is true high blood pressure and when it is white coat syndrome high blood pressure. This syndrome appears due to the patient’s fear of having to go to the hospital. One of the benefits of measuring blood pressure at home is that it helps you get the most accurate readings.
• Not only that, measuring blood pressure also helps you reduce unnecessary costs due to having to go to medical facilities to have your blood pressure checked. In addition, being self-sufficient at home also helps you save a lot of time to take better care of your health.

Experts encourage everyone to monitor and measure blood pressure at home. However, there are special subjects who are recommended to use this method to closely monitor their health situation and prevent bad situations from occurring at any time, including:

• People with obesity, overweight and diabetes
• People with a history of high blood pressure or low blood pressure.
• People who have just been diagnosed with high blood pressure and are undergoing medication treatment under the guidance of a specialist.
• Older adults or anyone at high risk for high blood pressure.
• Women who are pregnant and especially in the last 3 months of pregnancy. They are very susceptible to gestational diabetes. One of the signs of the disease is abnormally high blood sugar levels.

In this article, let’s learn useful information about spectrophotometers to have the most general overview of the functions, uses and structure of this type of device.

Before jumping into learning about spectrophotometers, let’s review a little about the concept of spectroscopy, so that we can understand the knowledge below more easily.

What is a spectrophotometer used for?

A spectrometer (spectrometer) is a specialized device used to separate, quantify and analyze the spectrum of light, specifically from a spectrum of complex light, it will be analyzed into simple light rays. . Based on the intensity and wavelength of the separated light when passing through a sample (solution or solid), engineers can use it to study the properties of this object and determine its color. , check the composition and structure of materials, determine the content of substances in any solution….

Because spectrophotometers can be used for many different purposes, one type of machine cannot do all the functions. Therefore, developers have created many different machine models to meet specialized applications (To learn more about machine types, please scroll down below).

Principle of operation of the spectrometer

After reading and understanding the basic structure of a spectrophotometer, surely the operating principle of this machine is no longer too difficult for you, right? Briefly summarized as follows:

Step 1: When starting the device, the light source will emit multi-color light to provide for the analysis process.

Step 2: Multicolored light will go from the light source into the collimator. Here, divergent light rays will be converted into parallel light beams.

Step 3: The parallel light beam will continue to go to a dispersion system that can be a prism or diffraction grating to separate white light into monochromatic bands of light with different colors (wavelengths).

Step 4: Monochromatic light, after passing through the dispersion system, will reach a baffle to select the wavelength (Wavelenght Selector). You can choose the wavelength you want by adjusting the dispersion system (like clip).

Step 5: The selected monochromatic light will pass through the partition and into the dark chamber. Here, light will shine through the sample to be analyzed and displayed on the projection screen for you to observe.

Step 6: With the integration of the Detector on today’s modern spectrophotometers, you probably won’t need to put your eyes into the microscope like on old equipment. Light passing through the sample will be sent straight into the detector, go through the data processing circuit and display the analysis results on the device’s screen.

In today’s article we talk about the top 5 mistakes in the installation of a water pump and how to effectively install this key element of the cooling system.

Installing a water pump: Mistakes

1. Cooling System Preparation

One of the main and often overlooked problems is in the preparation of the system through which the water pump will circulate the coolant.

Before installing a water pump it will be especially important to flush, drain and refill the cooling system with the OE (original equipment) specified coolant mix. On the contrary, the correct operation of the new water pump would be jeopardized.

When preparing the cooling system, if you notice that the old coolant is very dirty, it is advisable to check the thermostat and replace it if necessary. If you’re unsure how to check thermostat car, ensure you follow proper steps, including inspecting the thermostat for signs of malfunction and verifying coolant flow behavior.

2. Improper mix of coolant and water

Another common error is found in contamination caused by the incorrect mix of coolant and water or its improper use. Contaminated or improperly mixed coolant can cause corrosion problems, the dreaded cavitation, and cause leaks between the two contact faces of the water pump’s dynamic seal.

When choosing the right coolant, it is essential to check the expiration date and follow the vehicle manufacturer’s recommendations, as each individual engine is made from different materials and has specific needs.

3. Incorrect use of sealing paste

The use of sealing paste in the water pump is only necessary in those that are supplied without a gasket. Otherwise, if we add sealant when it is not needed, we will cause any particle of sealing paste that circulates through the cooling circuit coming from the pump gasket, which may affect the functionality of the dynamic seal, preventing the correct sealing function and causing a failure premature of it.

Incorrect use of sealing paste will directly affect the life expectancy of the water pump. Therefore, unless specified or referenced without a gasket, avoid the use of sealants.

4. Water pump dry rotation

Another mistake to avoid during installation is dry rotation of the water pump.

When refilling the cooling circuit after replacing the water pump, many manufacturers recommend that the pump be turned by hand until it is full. This fine-tuning of the pump can reduce the possibility of loss of the “mechanical” seal since the coolant liquid reaches the component of the mechanical seal creating a film that will prevent its spillage.

Otherwise, if the pump runs dry, it will cause damage to the seal, which may lead to premature leaks or squeaking noise in the water pump.

5. Water pump and timing belt

One of the most common mistakes is to overlook the distribution when we are doing the installation of the new water pump. The water pump is driven by the belt transmission system, which means that combining the replacement of both systems improves the quality and the safety of the process, which is why it is a highly recommended practice.

Previously the replacement of these two components was carried out separately, but nowadays it is more and more common to carry out this operation at the same time. This allows better vehicle performance and longer average lifespan of the water pump.

If the timing belt and other related items are installed incorrectly, this will directly affect the performance of the water pump.

Let’s dive into this crucial component in modern vehicles and get a comprehensive overview of what a car alternator is, exactly how an alternator pulley works and what are the main types.

What is a car alternator?

With the battery and the voltage regulator, the alternator is one of the three major components needed to generate power for the electrical components.

Its primary role is to convert mechanical energy from the engine into electrical energy. It is connected to the engine by a belt, so when the car is running the alternator generates, by using a rotating magnetic field, the electrical power to feed the system and charge the battery of the car.

Alternator has many different components, and each has their own dedicated function. Among the three major components are:

• Rotor
• Stator
• Rectifier (several diodes)

Besides these key components the automotive alternator also includes a voltage regulator and an alternator pulley.

How alternator pulley works

With the ever-increasing number of auxiliary systems that require more powerful alternators and, since the alternator contributes to the fuel consumption the increasing requirements on emissions have started an interest in developing alternator pulleys to deal with engine torsional fluctuations.

An alternator pulley is a device that allows a vehicle’s alternator to be turned by a belt, which is driven off of the engine’s accessory drive system. That is, when the engine remains idle, it remains at enough speed to produce sufficient power for maintaining the battery’s charge.

Today, an increasing proportion of cars are equipped with Overrunning Alternator Pulleys (OAP).

Types of alternator pulleys

There are 3 major types of alternators pulley: solid pulley, OAP and OAD.

• Solid Alternator Pulley: It used to be the automotive industry standard during many years, evolving from the V-belt type to the poly-V type. The only function of the Solid Pulley is to drive the alternator. And unlike the other pulleys, it does not incorporate a protective cap.
• OAP: The Overrunning Alternator Pulley, or “one-way clutch”, allows the alternator to wheel freely when the drive belt speed is suddenly decreased. That is, allows the rotor of the alternator to coast to a stop when the engine is shut down. This “overrunning” feature eliminates chirping sounds that happen during engine shutdown quickly causing the belt to slip at the alternator pulley.
• OAD: The Litens OAD not only has a one-way clutch inside, it also incorporates a patented internal spring mechanism (a torsion spring) required to absorb energy. Its design is tuned (engine specific) to absorb base engine vibrations (cylinder firing pulses) before they reach the alternator rotor and therefore negatively affect the accessory drive.

Among its main benefits, there are:

1. 1. Less tensioner motion
   2. Improves engine feel by reducing NVH
   3. More robust accessory drive.

In other words, the different parts of the system as the alternator, the water pump or other accessories bearings will last much longer.

With that being said, as these pulley types are not interchangeable, it is very important only to use the pulley type that the vehicle was originally equipped with. Always replace the OE pulley technology with the same Aftermarket technology.

Distinguish between “original” Forks and Aftermarket Forks

• “Factory” (Stock) forks, also known as original vehicle forks, have been manufactured and equipped by many manufacturers from the time they leave the factory.
• Aftermarket custom forks are forks researched and developed by toy manufacturers to change the quality of shock absorbers on each individual chassis system.

Normally, a Shock Absorber Set for 2-wheel drive (4WD) vehicles will include 4 Forks (2 front & 2 rear) and a Spring system (or torsion bar). Replacing the suspension system will make it easy for you to notice the change, almost immediately

When should you replace the Suspension System?

If your car is about to face situations like the one pictured below, it’s best to prepare yourself to upgrade the suspension system.

How to choose suitable shock absorbers

To choose a suitable shock absorber, you first need to answer a few questions such as:

• Do you often carry heavy loads?
• Are you planning on adding a bumper or winch?
• Which driving feeling do you like? Floating or firm when cornering.
• Estimated budget that you will spend?

Once you have clearly understood each of the above criteria, choosing shock absorbers will be much simpler, as today, custom fork manufacturers classify different fork codes according to each vehicle configuration or driving feeling. each person.

In addition, if you need to upgrade toys in the future such as Bumpers or Winches, you should also calculate to choose appropriate shock absorbers, because just placing an additional 15-20kg in front of the car will have a huge impact. greater than the lifespan of the original shock absorber.
