ZJP series roots vacuum pump with overflow valve (referred to as the roots pump hereinafter) are positive displacement pumps with two symmetrically shaped impellers, shaped like the figure “8”, rotate in opposite directions inside the pump housing. Roots pump are generally used to increase the pumping speed and/or to reach a higher end-vacuum on the pump system. Roots pumps are able to run at high rotation speed, as high as 1500~3000rpm, as the impellors are rotating non-contact. Due to the high rotation speed it is possible to have a high pumping speed with a relative small sized pump. It is possible to pump high quantities of gas in combination with a relative small backing pump. The energy consumption of such a system is much lower than of a single backing pump with the same pumping speed. The by-pass valve is mounted between the inlet and the exhaust and controls the pressure difference by opening and closing the by-pass valve by gravity. When the pressure difference between the inlet and exhaust is too high the by-pass valve will open and protects the Roots pump from overheating. This way it is possible to run the Roots pump at the same time that the backing pump starts and achieving the maximum pumping speed, also at higher pressures. There are two kinds of vacuum pumps, corrosion and anti-corrosion. The anti-corrosion roots vacuum pump is coated with Teflon or Ni-p by customer’s request. Also clients can choose skeleton oil seal or five point type oil seal by there own will.
This kind of pumps has the specialties as follows: 1)If there isn’t vapor to generate, You can turn off the adulterating-gas valve to increase the vacuum degree. 2) The improvement of the adulterating-gas valve can make the pump have adequate adulterating gas amount as pumping vapor, so the cogulable gas can be eliminated timely and the pump oil can be prevented from being lactic. 3) It is installed with the device that can make oil revival in which the oil,water and vapor can be frozen and separated, so the oil can be cleaned in time, and be used repeatedly,therefore, the working time of the pump is prolonged and the working reliability is increased.
This series of vacuum pumps can be used by themselves or as the backing pumps of the Roots pumps,diffusion pumps,molecule pumps and titanium pumps.With the adulterating-gas valve,the pumps can suck a little coagulable gas,humid air or the mixture of gas and vapor,but which can not contain particle-shaped solid matter.
W series of pumps adopt the circle-shaped stationary valve and its ultimate pressure (absolute pressure) is lower than 2600Pa,while the WY series of pumps adopt stripe-shaped moving valves,and it’s ultimate pressure is lower than 1300Pa? This series of pumps are principally used in the trade of chemical industry,medicine-manufacturing,light industry, architecture material and wiring etc..We also serve the no-oil pumps according to the demand of user.
WL series of standing reciprocating vacuum pumps are the renewed products based on the primeval W series of lying ones.Compared with the W series of ones, they have the specialty as follows: 1) The gas valves are installed on the cover and neck of the cylinder(the W series ones are on the body of the cylinders),so it can increase the area of cooling water.The process of compressing gas is approximately isothermal,so it can decrease the loss of power and can save energy by 10%~15%.The area it holds can decrease by 1/2. 2) The piston of the lying reciprocating vacuum pump will go down because of the weight of itself ,so it will be worn away unsymmetrically. The WL series of ones improved this shortcoming,it can decrease the wearing away of the moving units as piston and connecting pole; 3) We can serve the no-oil WL series of standing reciprocating pumps.
JZJ2S type Roots-water ring vacuum system consists of the major pump i.e. ZJ type Roots vacuum pump and the backing pump i.e. two stage water ring vacuum pump. It can pump not only the common gas but also the gas that contains vapor and a little dust. Compared with the common mechanical vacuum pump and water ring vacuum pump, it has some advantages as follows: it can endure the oil,vapor and tiny dust,its ultimate vacuum is high and its pumping speed in higher vacuum is great,so it is a kind of ideal vacuum-obtaining equipment for drying,dehydrating and gas-expelling in the trade of light-spinning,grocery and chemical industry etc..
2SAT (double stage), 2STC double stage), SKC (single stage) series cone type liquid ring vacuum pumps adopt the international advanced manufacture technology. The cone type allotter structure make the area of suction and discharge port end, flow resistance minish, the speed of pumping enhance, the energy conservation effect is obvious.The base exhaust structure reduces the bearing stress, the service life is long, safe and reliable. This kind of product especially qualify processes of the high dust gas, including the soft fiber unclean gas, with partial liquids the gas, the high temperature gas, virulent or caustic gas and so on , widely applied in electric power, papermaking, petrochemical, coal etc industries.
2sk Series Of Two Stage Water Ring Vacuum Pumps Whose Suction Speed Is Great Even In Higher Vacuum, Are More Fit To Work When The Suction Pressure Is Between -0.085mp A And -0.095mp A.
Application SK series water ring vacuum pump and compressor are used for sucking and compressing air or other noncorrosive, nonsoluble gases which don’t contain solid grains to obtain certain vacuum and pressure in sealed vessele. The gas sucked in may be allowed to contain small amount of liquid. The vacuum pumps are used widely in mechanical, petrochemical, pharmaceutical, food and confectionary industries as well as in electron field. AS the gas is compressed isothermally in the process.so that it cannot be likely to result in any danger upon compressing or extracting flammable and explosive gas,thus making it more widely used. Features •It is designed with compact structure , thus make the maintenance more convenient; •It is widely used in compressing or extracting flammable, explosive gases which is allowed to contain vapor and small amount of liquid; •Using water as main working liquid, thus it can optimize the cost of maintenance; •It can be used under more rigid working condition.
