2XZ type two-stage rotary vane vacuum pump 2014

■ 2XZ type two-stage rotary vane vacuum pump Product Overview: 2XZ type two-stage vacuum pump system speed direct-linked structure rotary vane vacuum pump. It has eccentrically mounted in the pump rotor cavity, and rotary vane rotor slot. Rotor rpm drive rotary vane, rotary vane against the cavity wall, the intake and exhaust ports separated, and the intake air volume chamber volume cyclically expanded and the intake and exhaust chamber volume is periodically refine and compressed gas, pushing the exhaust valve exhaust, resulting in a vacuum. Figure 1 shows the single-stage pump works Fig. Two-stage are two single-stage series. 2XZ type two-stage rotary vane vacuum pump is equipped with a gas ballast valve, with extended use of time and prevent pump oil pump oil mixing with water effect. 2XZ type two-stage rotary vane vacuum pump with small size, light weight, low noise, and easy start. In addition, there are measures to return the oil (2XZ-8) and no seal leakage prevention measures to prevent contaminated sites. 1,2XZ type two-stage rotary vane vacuum pump is to obtain basic equipment, it may be alone, but also as various types of high vacuum system before the pump and pre-pumped. 2, the pump inlet open to atmosphere continuous operation should not exceed three minutes. 3, the pump is not suitable for pumping corrosive to metal, to pump oil from a chemical reaction gas containing dust particles to form high oxygen, explosive gas. 4, compression pump or pump something to do with the pump. 5, the pump working conditions: the temperature range of 5 ℃ -40 ℃, relative humidity less than 90%, air inlet pressure of less than 1333Pa conditions allow long-term continuous operation. 6, when attached to the power supply, electrical wiring according to the provisions of signs, attention should be consistent with the direction of the arrow on the carriage of motor rotation. 7, pipe continuously pumping the vessel, its diameter should be not less than the pump inlet diameter, and the pipe should be shorter and less elbow, while paying attention to leaking pipes. 8, each focusing Check the oil level before starting to pump stops oiling to 4/5 the height of the oil standard glass diameter is appropriate. 9, with the use of clean pump oil pump oil SY1634-70 1st. 10,2XZ type two-stage rotary vane vacuum pump can start at once through the atmosphere or any vacuum. XZ-1 single-stage pump if the start-up difficulties, dial start to fall into the breather plug cap, then put into operation. ■ 2XZ type two-stage rotary vane vacuum pump Model significance: ■ 2XZ type two-stage rotary vane vacuum pump range: 2XZ type two-stage rotary vane vacuum pump and its performance by the high pressure stage and low pressure stage, its suction port and vacuum vacuum device is connected, in operation a gas container to intake and discharge. When the equipment is a vacuum, high pressure stage exhaust valve closed, high-level and the gas will be transferred to the second stage, and by the second stage suction and discharge, vacuum equipment available certain vacuum. Technical parameters of the pump is 6 × 10-2pa, pump and motor coupling, high speed, appearance, compact structure, easy mobility work, our company metal scraping for diffusion pump before the pump, precision instruments and laboratory support, medicine, food packaging, electronics and other units.
