2X-Series

The type two-stage oil-sealed mechanical pump system varactor vacuum pump, which has the characteristics of the exhaust directly to the atmosphere is suitable for electronics, refrigeration, electric light, chemical, medical, bottle lamps, packaging, dehydrating, drying and other industries. (But can not be used for extraction of oxygen is too high, there are explosive, corrosive to metal on the vacuum oil from the chemical reactions, as well as containing the particles, dust, gas, also can not serve as pumps and compressors use.Motor power:0.37~5.5KW,extract capacity:2~7L/S,Limit vacuum:6×10-1Pa。

Q: What are the meanings of the vacuum pump, the front pump and the main pump?: The main pump can be understood as a booster pump, used to improve the vacuum mechanical pump with pumping quantity. As the roots pump, diffusion pumps, molecular pump. These can not use (too much pressure) so the need for mechanical pump drainage, the vacuum chamber is pumped into the rough vacuum, then the main pump starts to work.

Q: What is the difference between swashplate pump and crankshaft pump?: Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights his advantage.

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.

Q: What are the important parameters of the pump?: Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and acceleration of gravity, is the effective energy output from the pump in unit time of liquid -- effective power pump:Pe= P gQH (W) = QH (W)In the p - density of liquid pumping (kg/m3);Gamma - pump heavy liquid delivery (N/m3);Q - pump flow (m3/s);H - pump lift (m);G - gravitational acceleration (m/s2)The shaft power P and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said.

Q: What's the pump? Where can I use it?: Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to classification according to the working principle, it can be classified and named according to other methods.

Q: How to install, operate and maintain the pipeline booster pump?: Should be "People's Republic of China network security law" requirements, since June 1, 2017, the use of Internet services to carry out real name authentication account. In order to ensure your Baidu account can be used normally, please check the account number as soon as possible. Thank you for your understanding and support.How to install, operate and maintain the pipeline booster pump?Brother Yao s Gc76 2547 | browseRecommended for 2016-12-01 23:52:54 best answerThe installation of booster pump must be installed horizontally or vertically according to the installation method. The direction of flow shall be consistent with the arrow on the pump body, and installed as far away from the water level as possible. A valve shall be installed on the pump inlet line for ease of use and maintenance. When the impeller is the aspiration level below the pump on the pump shaft end or around the pump should be installed check valve, the outlet is connected with 13 links for water use, at first use to pump should be filled with water, and tighten the screw plug. The pipe connection should be tight, especially the water inlet pipe can not leak, otherwise it will reduce the pump head or not pumping water. The pump cavity is not water, not a long time running, so as not to damage the seal

Q: What does electromechanical vector pump mean?: Commercial buildings: hotels, office buildings, department stores, large saunas, etc.Irrigation: such as parks, playgrounds, orchards, farms, etc.Manufacturing: such as manufacturing, washing equipment, food industry, factories and so on

Q: What is pump suction work?: Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.

Q: What is the pump delivery? What's the difference between years and years?: First of all, as a student majoring in insurance, I strongly condemn the first floor of ignoring practice and trampling on real knowledge!!The insurance industry criticized a lot, but it is required for many people, we should face and try to maintain the healthy development of the industry, the first floor of the insurance you have not done, have no contact with the insurance, insurance, not to dictate the nonsense, more should not be here misleading!

Q: Water pump does not produce water, what are the reasons?: 1 check whether the motor is reversed.2, to see whether the export, the entrance blocked, the outlet pressure gauge whether there is pressure.3, whether the pump selection is wrong, you can not suck up the water.
