Our company is a complete vacuum pump set production and processing system of manufacturing enterprises, main vacuum pump set series of mechanical equipment production and sales, committed to use excellent product quality and thoughtful service to reward new and old customers.
Water ring vacuum pump is simple in structure, low in manufacturing accuracy and easy to process. Easy to operate and maintain. Generally, it is directly connected with the motor, and the revolution is higher. With the smaller size of the structure, can get a larger amount of exhaust, in the power, petrochemical, manufacturing, pulp and paper production, plastic packaging and other industries have been widely used. Below, the manufacturer of vacuum pump sets a brief description of a launching ring vacuum pump in the extraction of flammable liquid details.
1. Pay attention to type selection. Before applying water ring vacuum pump for operation, the type of water ring vacuum pump suitable for the operation item should be selected. The type of water ring vacuum pump mainly depends on the pumping medium, the amount of air needed for work, the vacuum degree or exhaust pressure. If the type of vacuum pump or vacuum unit is selected, it is necessary to choose the correct type according to the amount of pumping required by the system.
2. Pay attention to equipment Settings. Corrosive resistant water ring vacuum pump should be selected to extract flammable and explosive liquid. When the vacuum container containing flammable and explosive liquid, corrosion resistance between water ring vacuum pump and the container must be equipped with a vacuum tank, first of all, the water ring vacuum pump vacuum tank to the limit under vacuum, and then close the pump and the vacuum tank valve, to open the container and the valve between the vacuum tank container liquid and air inhaled into the vacuum tank.
3. Pay attention to operating efficiency. As far as possible, the vacuum degree of the selected vacuum pump is required to be in the efficient interval, that is, in the critical vacuum degree or critical required exhaust pressure area, so as to ensure that the vacuum pump can work in accordance with the required conditions and requirements. Avoid operating near the maximum vacuum or exhaust pressure range of the vacuum pump. Operating in this area, not only the efficiency is very low, and the work is very unstable, easy to make the vacuum pump vibration and noise.
