Description
[technical field]
The utility model relates to a kind of vacuum pumping device.
[background technique]
At present, all to use vacuum pumping device in a lot of situations in chemical industry, pharmaceutical industry, the maximum deficiency of tradition vacuum pumping device is: the reliability of work is poor, the control of energy-conservation aspect is undesirable, above-mentioned 2 deficiencies often a lot of enterprises seldom paid close attention to because this can involve a large amount of inputs of equipment technological transformation.
[summary of the invention]
The utility model provides know clearly a kind of reliable operation, low cost, has simultaneously the vacuum pumping device of energy-conservation advantage.
The utility model is implemented by following technical solution:
A kind of vacuum pumping device, is characterized in that; Comprise vacuum storage tank, vacuum pump and elevated tank, the air inlet duct of vacuum storage tank is provided with electronic control valve, the outtake tube of vacuum storage tank and the bleeding point of vacuum pump join, cooling water intake and the elevated tank of vacuum pump join, be provided with the high-low water level sensor in elevated tank, electronic control valve, low water level sensor are electrically connected to the stop switch of vacuum pump.Described vacuum pump parallel connection is provided with two.
Adopt the vacuum pumping device of technique scheme, can realize reliable operation, low cost and energy-conservation, principle is: 1. do not adopt advanced technology and equipment in said apparatus, cost is low; 2. electronic control valve opens and closes automatically according to the vacuum condition of work system, controls simultaneously the operation of vacuum pump and stops, and reaches energy-saving effect; 3. elevated tank can guarantee the necessary water cooling of vacuum pump operation, and when the elevated tank low water level, it is out of service and send alarm signal that low water level sensor can in time be controlled vacuum pump, guarantees the reliable operation of vacuum pumping device; 4. two vacuum pumps that are arranged in parallel are worked simultaneously and can be made rapidly work system reach the vacuum requirement, and one standbyly can switch and devote oneself to work at any time at ordinary times, guarantee system reliability.
