Product Description

Because of its structural characteristics, the capacity of the slide valve pump is much larger than the rotary vane pump, so it is often used in large vacuum equipment. Slide valve pump has two types of single stage and double stage. The ultimate pressure of the single-stage pump is less than or equal to 0.6Pa for the small pump, or less than or equal to 1.3Pa for the large pump, and the ultimate pressure of the two-stage pump is less than or equal to 0.06Pa (closing gas). Maximum pumping speed of bipolar 2H slide valve vacuum pump is 300L/S.

Because the rotary mass of the slide valve pump has a larger eccentricity, if the slide valve does not have a good mass balance, it will produce larger vibration in operation. However, the motion trajectory of the pump rotating centroid is a closed curve with complex shape, so it is difficult for small factories to achieve a complete balance of the inertia force of the spool valve pump. The mass balance of slide valve can be done by dynamic balance test and double or three cylinder structure.

Roots slide valve vacuum unit is a vacuum unit composed of ordinary roots pump as the main pump and slide valve vacuum pump as the front pump in series. Through vacuum relay or electric contact pressure gauge, to realize the automatic opening and closing of roots pump slide valve pump, automatic overload protection. The whole unit is mounted on a frame, equipped with pipes, valves, electrical operation control box, cooling water pipe system. Unit structure is compact and easy to use.

According to the size of the system being vacuumed and the difference of the ultimate pressure, the nominal pumping speed ratio between the pumps of the vacuum unit is generally between 4: and 10:1, the former is more suitable for larger vacuum system and the latter for a long time in lower inlet pressure or ultimate vacuum. This series of units in order to prevent the slide valve pump shutdown oil return, in the front stage inlet pipeline equipped with electromagnetic charging valve, its action and the front stage pump motor linkage, when the slide valve pump stop pumping, to the pump mouth inflation, to ensure that the vacuum oil in the slide valve pump to return to the tank, at the same time to prevent the vacuum system by vacuum oil pollution.

Roots slide valve vacuum unit has significant energy-saving effect, high vacuum degree, high vacuum range of large gas extraction, can be widely used in the power industry transformer, wire and cable, capacitor vacuum impregnation, vacuum drying process. Vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filtration, freeze drying; Ideal vacuum equipment for aviation simulation test. If the gas containing a small amount of steam or dust is pumped, a filter device should be installed.
