Rubber pipe refers to the pipe used for gas transmission, often used in gas welding, gas cutting, various gas welding, plasma arc welding and cutting. There are two kinds of welding rubber pipe, according to the national standard blue pipe for oxygen pipe, the maximum pressure is 1.5mpa; Red tube or black tube for acetylene tube, allow the use of pressure 0.5 ~ I.OMPa. The characteristics of rubber tube are physiological inertia, UV resistance, ozone resistance, high and low temperature resistance (-80 to 300 degrees), high transparency, strong resilience, compression resistance permanent deformation, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame resistance, voltage resistance, electrical conductivity and other properties.
Supporting electrical appliances, electronics, furniture equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, cars, motorcycles, ships, aviation, harsh working environment wire coat comb water, for many materials, can play a role in isolation and other fields of industry.

In the process of using the vacuum pump, often encounter the problem of high motor temperature, then in such a problem, how should we find the reason, and then find the appropriate response? Vacuum pump The reasons for high motor temperature and countermeasures are as follows. Vacuum pump motor temperature high causes and countermeasures 1, the cause analysis (1) motor power, operating current, heat. (2) The fan speed is low, wind pressure, air volume is small. (3) fewer fan blades, resulting in a small amount of wind. (4) motor with dust, oil, reducing the cooling capacity. (5) The voltage of the bus where the vacuum pump motor is located is 380V. Due to the voltage drop of the cable and the uneven distribution of the load, the actual voltage applied by the motor is only 365V, which causes the running current to be large due to the low voltage. 2, Countermeasures Motor power, speed and vacuum pump match, can not be changed. Fan mounted on the motor shaft, the motor speed determines the fan speed, it can not be replaced. Although increasing the number of fan blades can play a role, but the increase in the number of blades, the dynamic balance is not easy to find, such as finding is not good, will cause increased motor vibration. (1) Lengthen the original fan cover 40cm, install a fan with the same diameter inside the axial fan, axial fan motor power 850W, speed 1489r / min, voltage 380V. The original fan to keep. Axial flow fan set up all the way to power control, axial fan and the main motor without a chain. After the start of the vacuum pump to start the axial fan operation, the vacuum pump outage after 30min axial fan, so that the main motor is fully cooled; (2) Regularly remove the motor dust, keep the motor heat sink clean, increase its cooling capacity; ( 3) The bus where the vacuum pump voltage is adjusted to 400V.
