UK GRIMM imported water ring vacuum pump summary:
imported water ring vacuum pumps and compressors are used to pump or press gas and other gases without corrosion, insoluble and non solid particles, so as to form a vacuum or pressure in a closed container to meet the requirements of the process flow. A small amount of liquid is allowed to be mixed in the gas that is inhaled or pressed.
UK GRIMM imported water ring vacuum pump working principle:
The impeller is eccentrically installed in the pump body, so when the impeller rotates, the water is driven by the centrifugal force and forms a rotating water ring on the inner wall of the pump body. The inner surface of the upper part of the water ring rotates along the arrow direction tangent to the hub, and the inner surface of the water ring is gradually separated from the hub during the first half process, because this forms the closure between the impeller blades and the water ring. In space, with the rotation of the impeller, the space gradually expands, the pressure of the space gas is reduced and the gas is entered into the space. In the back half process, the inner surface of the water ring is gradually close to the hub, the space between the blades gradually diminishing, the pressure of the space gas rises, and the gas between the blades is discharged when it is higher than the vent. Every time the impeller rotates one week, the space between the blades is sucked up once, and many spaces work continuously, and the pump continuously suck or pressurized the gas.
In the process of work, doing work to produce heat, will make the working water ring heat, while a part of the water and gas are discharged together, therefore, in the working process, the pump must be continuously supplied to the pump to cool and supplement the water consumed in the pump to meet the work requirements of the pump.
When the gas of the pump is no longer used, there is a gas water separator at the end of the pump (which can be replaced by a water tank.) the waste water and the part of the water are discharged into the gas water separator. The gas and water are separated, the gas is discharged from the exhaust pipe, and the water left behind is supplied to the pump to continue to use. With the prolongation of working time, the temperature of the working water will increase continuously. At this time, a certain cold water (tap water) should be supplied from the water separator of the gas water separator in order to reduce the temperature of the working water, so as to ensure that the pump can meet the required technical requirements and indicators.
When used as compressor, the exhaust port of the pump is connected with a gas water separator, the gas water mixture enters the gas water separator and automatically separates. The gas is transported from the exhaust pipe to the required system and the working water is discharged automatically through the switch. When the gas is compressed, the working water is extremely hot, the water is discharged from the pump outlet and the temperature will become higher because of the water. At the bottom of the gas water separator, it is necessary to supply cold water continuously to supplement the hot water that has been released, and to cool the working water, so that the working water temperature is not too high, thus ensuring the performance of the compressor, reaching the technical index, and meeting the technical requirements.
UK GRIMM imported water ring vacuum pump structure description:
The imported water ring vacuum pump is composed of pump body, two end covers, impeller, shaft and other components. The intake and exhaust pipes are connected to the pump cavity by the suction hole and the exhaust hole installed on the disc of the end cover. The shaft is installed in the pump body eccentrically, and the impeller is fixed on the shaft with a flat key. The total gap between the two end surfaces of the water ring vacuum pump is adjusted by the cushion between the pump body and the disc. The clearance between the impeller and the end cap is adjusted by the SK-1.5/3/6 or the back cap (SK-12/20/30), and the above axis of the SK-42 is in interference with the impeller. The gap is determined by the front end positioning, and the SK-42/60/85/120 is no shaft. The rest of the structure is the same as that of SK-6/12/20/30. The clearance between the two end faces of the impeller and the end plate determines the size and ultimate pressure of the gas flow in the pump chamber from the intake port to the exhaust port.
The packing of the imported water ring vacuum pump is installed in the two ends of the cover, and the sealing is not entered through the small hole in the end cover, and the cooling filler is reinforced and the sealing effect is enhanced. The replenish water needed for the impeller to form a water ring is supplied by the water supply pipe, and the water supply pipe can be connected with the gas water separator to circulate water supply.
The SK type water ring vacuum pump adopts the mechanical seal in the form of sealing, and the mechanical seal is installed in the packing cavity, and the packing is omitted. The packing gland is replaced by a mechanical seal gland and the rest of the structure is the same.
The bearing is fixed on the shaft by the nut of the garden.
The imported water ring vacuum pump is equipped with a garden disk on the end cover, and there are suction, vent holes and rubber ball valves on the orchard. The effect of the rubber ball valve is that when the gas pressure between the blades of the impeller reaches the exhaust pressure, the gas is discharged before the vent, reducing the power consumed by the excessive pressure of the gas, thus reducing the power consumption.
UK GRIMM imported water ring vacuum pump technical parameter:
Maximum pumping capacity: 0.15-120m3/min
Water consumption: (4-5) ~ (220-260) L/min
import and export caliber: 25-300mm
Limit vacuum degree: 0.091-0.098MPa
UK GRIMM imported water ring vacuum pump scope of application:
Widely used in machinery, petroleum, chemical, pharmaceutical, food, ceramics, sugar, printing and dyeing, metallurgy and other industries. In the process of working, the compression process of the pump is carried out in an isothermal state, so it is not easy to be dangerous when flammable and explosive gas is pressed and pumped, so its application is more extensive.
