Vacuum pumps ABV-70
Vacuum unit Avookoltseva ABV-70 is designed to create a stable vacuum necessary for machine milking on milkmaid installations, for operation in areas with moderate climate in rooms temperature from 0 to +30 ºС and height above sea level no more than 1000 m. The unit can operate from any drive that provides power and rotation frequency of the rotor. The unit with a three -phase engine operates in prolonged mode from an alternating current network with a rated frequency of 50 Hz, with a rated voltage of 400 c.

Figure 2 shows two diagrams of recirculation water supply of the pump. The choice of any of them depends on the conditions for placing the pump in a vacuum room. Water supply pipeline 2 is connected to the pump fitting. The lower end of the water supply pipeline in order to avoid the impression in the pump entering the pump should be located at a distance of at least 150 mm from the bottom of the container. The exhaust pipe 4 is installed in the upper part of the container above the surface of the water filling it.
The volume of capacity 1 is selected at the rate of at least 200 liters of water per pump, which provides the working temperature of the water during the pump operation of not more than 40 ° C.
The vacuum pump 3 with a suction pipe is connected to the vacuum pipeline of the milking installation by means of rubber couplings 5 through the fuse 6, which acts as a check valve
The container is filled with tap water and during operation the water level in it is maintained by 85 - 90 % of the capacity.
The pump is turned on and off is made by the starting button control device and protection of the drive electric motor.
Before the initial turned on the unit after installation or a long break of its operation, it is necessary to pour 1.5 - 2 liters of water through the water supply pipe in the pump chamber.
