When it comes to car maintenance, many people will “over-protect†the car. The result is often self-defeating. It not only fails to achieve the goal of maintaining the car, but also destroys the car. Here's a look at some of the wrong ways to maintain.
First, the circle way waxing: the effect is poor Many people wax the body habitually carried out in a circle, this is not the correct way. The correct way of waxing is to use a straight line, horizontal and vertical lines alternately, and then the last one in the direction of rainwater flow, so as to achieve the effect of reducing concentric rings of halo on the paint surface.
Second, too much oil: failure When the engine oil sump in the engine oil is insufficient, bearing and journal friction will be due to less oil and poor lubrication, increase the degree of wear, and even lead to burning tile shaft accident. However, if the oil is too much, the crankshaft shank and the big end of the connecting rod will violently agitate when the engine is working, which will not only increase the internal power loss of the engine, but also increase the oil splashed on the cylinder wall, resulting in failure of the oil . Therefore, the oil in the engine oil pan should be controlled between the oil dipstick and the lower reticle.
Third, the bolt is too tight: the permanent deformation of the car with bolts, nuts connected many fasteners, should ensure that it has enough pre-tightening force, but it can not be tightened too tight, on the one hand will make the connector under the action of the external force Permanent deformation occurs; on the other hand, it will cause permanent deformation of the bolt, leading to a reduction in pre-tightening force, and even causing slipping or breaking.
Fourth, the fan belt is too tight: the bearing load is too high in summer, and some drivers think that the tightness of the fan belt is increased, causing the fan belt to become too tight. They do not know that this is wrong. The fan belt should be kept tight and tight, because over-tightening will lead to excessive bearing load, increased wear, increased power consumption, but also will make the water pump shaft bending, belt elongation deformation, shortened life.
Fifth, the new battery does not charge: Shorten the life The first charge of the battery is called the initial charge, the initial charge has a great influence on the service life of the battery. If it is not recharged, it will be directly added by using “waterâ€. The capacity of the battery will not be high and the service life will be shortened; if it is directly charged, it will also shorten the service life. Usually, the initial charge of the battery is performed after charging the electrolyte and charging it with a small current for about 1 hour.
Sixth, random addition of vehicle equipment: affecting traffic safety Private car is the owner of the mobile home, the pursuit of passenger comfort and luxury is understandable, but some owners do it yourself in the car to install a variety of equipment, this modification, if not handled properly, It often has an adverse effect on the convenience and reliability of the car's performance and operation, and it is easy to leave sequelae or affect driving safety.
Seven, the cooling water temperature is too low: wear the engine hot summer weather, some drivers in order to prevent the engine temperature is too high, blindly require the cooling water temperature as low as possible; some drivers in order to achieve the purpose of cooling, simply remove the thermostat These are all wrong. Automobile engines are both afraid of heat and cold. If the cooling water temperature is too low, fuel combustion will deteriorate, fuel consumption will increase, wear and tear will increase, oil viscosity will increase, and engine power will decrease. Tests show that when the cooling water temperature is 40-50 degrees Celsius, the engine wear increases by 60%-80%, the power is reduced by 25%, and the fuel consumption is increased by 8%-10%. Therefore, the temperature of the engine cooling water is not as low as possible, generally should be controlled at 80-90 degrees Celsius.
Introduction
our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torishpherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general as the below sketches
