Low suction pressure in pumps

The pump is the essential component for most hydraulic systems

The low suction pressure in the pump reduces the flow and the head delivered by the pump.

There are so many causes for the low suction pressure in the pump. Some of the common causes are described as below,

The primming of the pump is an essential process to avoid low suction pressure. The water flow is less than the requirement if the primming is insufficient. Ideally, the pump should be installed near to the resources of water. The pump’s flow rate is reduced if the pump is far from the source of the water. If the suction requires more power, the discharge is reduced. It would help if you kept the pump distance as per the specification of the pump.

The suction line diameter should be kept sufficient so that the flow can quickly reach the pump’s inlet. If the suction line area is reduced, it can cause a problem with the suction. Make sure that the suction line should not leak from anywhere.

The pump is operating with the impeller rotation in it. The direction of rotation is unique. Suppose it rotated in the reverse direction. The fluid will not get pressurized. This can happen because of faulty electric connections.

The radiant senor is a thermostat or a bimetallic switch. The radiant sensor of the flame designed as this process that it could easily detect the emission of the heat from ignitors or burner of the flame.

The process for a radiant sensor of the flame is describe briefly in the section of below,

  1. At the beginning of the process we need to open the bottom section of the dryer to access the panel or we need to open the door of the burner. After that dryer should be started by switch thus the process cycle can be continue for the heat demand of the system.
  2. In the next step the ignitors of the radiant flame sensor which is attached with the secondary coil and stays in series that it won’t draw enough current. The ignitor is cool than the booster coil and the current is shunted away from the hotter side of booster coil. As the net result the valve of the primary cannot be open and glow is not done by the ignitor as a result no flame is occur. It is the perfect time to check the sensor of the radiant flame.
  3. The switch of the dryer is off and the power card of the dryer is disconnected. Need to remove the dryer’s front if the burner is not assembly fully.
  4. Two wires which are attached with the burner funnel of the sensor of the radiant are disconnected.
  5. Ohmmeter probes are placed between two terminals of the sensor of the flame radiant. At this moment if the meters have no movement that means sensor not working properly. To check the ohmmeter working need to touch the probes, need to remove the bad sensor from the system. If the meter of the radiant sensor can read 0 ohm then the present sensor is good.

9. How does the hygroscopic property of brake fluid affect its performance?

The hygroscopic property of brake fluid helps to maintain the performance of the brake system by preventing water from pooling and causing corrosion. However, as the brake fluid absorbs moisture over time, it can degrade and its boiling point can decrease, potentially affecting brake performance.

10. How often should hygroscopic brake fluid be replaced?

Hygroscopic brake fluid should be replaced every 1-2 years, or according to the vehicle manufacturer’s recommendations. This is because over time, as the brake fluid absorbs moisture, it can degrade and its boiling point can decrease, potentially affecting brake performance.

Electrical Socket Types And Functions

The nine types of electrical sockets functions and their several facts are briefly describe in below,

A Type:

 It is one type of electrical socket type which mainly used for the domestic purpose. The countries where this type of electrical socket is uses they are Canada, United State, Central America, Japan.This type of socket is placed in underground with the help of two parallel sponges. The sockets have two blades which thickness is around 1.6 mm; length would be around 18 mm and the space difference around 13 mm. This A type socket is also known as NEMA-15.

The blades is not same to each other. The socket can be inserted in the system only one way they are polarized. The widths of the blades are different to each other. The sockets have rates about 16 A. One blade of the socket is attached with the neutral.

This is not insulated. They don’t have covering like the others types of electrical sockets. Black covers are not carried by this type of socket. The outlets of the A type sockets are not attached with the wall.

B Type:

The countries where this type of electrical socket is uses they are Canada, United state of America, Mexico.This type of socket is also placed in underground just like A type with the help of two parallel sponges. The sockets have two blades which thickness is around 1.5 mm; length would be around 15 – 19 mm and the space difference around 12.5 mm. This B type socket is also known as NEMA 5-15. The width of the B type socket is about 6.5 mm.

Earth pin is attached with this socket which shaped like U. The earth pin length is about 48 – 52 mm. The whole device is placed under the ground before the connection is attached with the power. The sockets of B type have rates about 15 A.

The distance between the two blades is about 12 mm.

This is also not insulated just like A type. They don’t have covering like the others types of electrical sockets such as C, D, E and many more. Black covers are also not carried by this type of socket.

C Type:

Almost every country where this type of electrical socket is uses. But where this type of sockets is not used they are Ireland, Cyprus, and United Kingdom.This type of socket is not placed in underground and none polarized not like A and B type. This C type socket is also known as CEE 7/16.

The sockets have two pins which shaped is round and length around 5 mm. length would be around 19 mm, if the length is consider from the center then length should be around 18.5 mm and from the  tip the length should be 17.5 mm. The sockets have two isolated sleeve and their length is about 9 mm long.

In this type of electrical socket less than 2.5 A power is required to generate. The sockets of C type have rates about 12 A.

These types of electric socket have very less frequency. This C type socket is uses in various developing countries all over the world. This type of socket is actually old form of E, F, G, H, type electric socket.

This C type electric socket is unearthed.

D Type:

This type of electrical socket is use in a wide range in India this is actually a British standard socket. The sockets contain earth pin which length would be around 21 mm and diameter of the socket is about 7.2 mm. The length of the line and neutral pin is 5 mm and 15 mm.The center space is around 18.9 mm. The distance length from the imaginary line of power pin and ground pin is about 22 mm. This C type socket is also known as British standard 546.
