Background
The PVC-U drain pipe is extruded from a host machine and then enters a water tank for cooling and shaping, wherein the shaping is a key control link for controlling the appearance size of the pipe to meet the standard, and the important principle of the shaping is that a real pump provides negative pressure, and the sizing sleeve adsorbs the pipe and then controls the appearance sizes such as the outer diameter, the out-of-roundness and the like. The equipment is started and then is operated for 24 hours, so that a vacuum pump for providing negative pressure for a water tank is also operated for 24 hours, in normal production, the negative pressure is often required to be very small, the negative pressure requirement of most machine tables is often less than two thirds of the full power, in order to adjust the outer diameter of a pipe, the negative pressure is adjusted in a mode of reducing the pressure through an emptying valve, and the operation has the following disadvantages:
1. the vacuum pump runs at full load for 24 hours, and the negative pressure for shaping the water tank is usually less than two thirds of the full negative pressure, so that a large amount of electric power is wasted and useless work is done.
2. When the size of the pipe is adjusted by reducing the negative pressure by using the air release valve, a large amount of noise is generated in a workshop due to the 'whistle blowing' principle, so that the noise pollution of the workshop is caused.
