What is a Ball Valve?

Image
The  ball valve  came out in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, in a short period of 50 years, it has rapidly developed into a major valve category. In the developed western countries, the use of ball valves is increasing year by year. Today, the  ball valve manufacturer  will introduce you to the classification and characteristics of ball valves. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly. Ball valves are most suitable for use as on-off and shut-off valves. Classification of ball valves Ball valves are divided into floating ball valve, fixed ball valve, orbital ball valve, V-shaped ball valve, three-way ball valve, stainless steel ball valve, floating ball valve, cast steel ball valve, forged steel ball valve, ash unlo...

How to Solve the Vacuum Pump Fault?

Image
Things will inevitably be damaged after being used for a long time. Vacuum pumps are used in many industrial fields on a large scale. What should I do if the vacuum pump is broken? What are the maintenance methods for vacuum pumps? Today we will learn together to understand the related content of vacuum pump maintenance. Vacuum pump  maintenance, problem 1. Vacuum pump can't start: The main manifestation is that the vacuum pump can't start running after powering on. At this time, you should first check the circuit part of the vacuum pump, such as whether the fuse is burned out, and whether the vitality parts of the circuit part are burned out. After troubleshooting the circuit part, the following two factors should be considered: 1. Motor burnt out: Mainly the stator coil of the motor is burnt out. There are many causes. For example, the momentary current is too large, the motor bearing is worn for a long time, which causes the bearing friction resistance to increase, the motor...

Precautions for using Submersible Pumps

Image
1. Avoid frequent switching The  submersible pump  should not be started too frequently, because when the submersible pump stops, it will produce backflow. If it is turned on immediately, the motor load will start, resulting in an excessive starting current. Therefore, after shutting down, wait for the water in the pipe to return to completion before starting again, usually about 5 minutes.   2. Avoid turning on when the power supply voltage is abnormal. Too high and too low voltage will cause the temperature of the submersible pump to rise too high, shorten the service life or even burn the submersible pump. Due to the relatively long low-voltage power supply lines in rural areas, it is common for the line end voltage to be too low and the starting end voltage to be too high. Therefore, in the process of using the submersible pump, the operator must always observe the power supply voltage value, if it is less than 10% of the rated voltage, more than 10% of the rated volt...

What Should Be Paid Attention to When Using Sewage Pump?

Image
  Sewage pumps  are also called blow-down pumps. There are self-priming non-clogging sewage pumps, vertical and horizontal pipeline sewage pumps; submersible pumps include industrial submersible sewage pumps and agricultural submersible pumps. 1. If the sewage pump has any minor failure, remember not to let it work. If the filler of the water pump shaft is completely worn out, it should be added in time, and the pump will leak air if it continues to use. The direct effect of this is that the energy consumption of the motor will increase, which will damage the impeller. 2. If the sewage pump vibrates strongly during use, you must stop and check the cause, otherwise, the pump will also be damaged. 3. When the bottom valve of the sewage pump leaks, some people will fill the inlet pipe of the pump with dry soil and flush the bottom valve with water, which is really undesirable. This is because when the dry soil is put into the water inlet pipe when the pump starts to work, the dry...
