vacuum equipment

Screw vacuum pump is an updated product of oil-sealed vacuum pump, which has been widely used in domestic pharmaceutical, chemical, semiconductor and other enterprises with higher requirements for clean vacuum. Screw vacuum pump USES a pair of screw in the pump shell for synchronous high speed reverse rotation and produced by the suction and exhaust effect of odor equipment If the screw vacuum pump operation is not good, it will lead to the import vacuum pump water, then what are the reasons will lead to screw vacuum pump water? 1, screw vacuum pump cooling circulating water too much, cooling circulating water back 2. The motor is burnt due to insufficient speed of the imported vacuum pump or overturning 3, improve the screw vacuum pump sealing box (alias packing), the upper water pipe T2 copper rod drawing twisted flange plate has leakage 4. Cold circulating water does not enter or the water pipeline is blocked, and the gate valve is not opened 5, screw vacuum pump

The screw vacuum pump is an air pumping device that USES a pair of screws to perform reverse rotation at the same pace in the pump shell to provide suction and exhaust functions. It can be applied in the field with more dust. Therefore, it is a basic job to carry out purging of the screw vacuum pump How to purge the screw vacuum pump I. cleaning and purging Screw vacuum pump cleaning purge is mainly used to remove corrosive, harmful or thick substances, such as: tree esters. Clean and purge usually before stopping the pump, turn off the gate valve of the inlet of the screw vacuum pump, and run it for 20 ~ 30 minutes after filling the inlet with hydrogen or water steam, to purge the screw vacuum pump cavity screw, and clean the residual process steam or thick adhesive material on the surface of the cavity. Refrigeration purge Refrigeration purge is used to refrigerate the inner cavity of the screw stator and screw vacuum pump. Screw vacuum pump, air inlet into the p

In the production of enterprises, often forget the water ring vacuum pump to drain oil, resulting in its surface oil many, small make up below to teach you how to drain water ring vacuum pump. If you want to replace all the oil in the tank of the water ring vacuum pump, you can unscrew the oil drain plug at the bottom of the tank to drain the oil. When the water ring vacuum pump is discharging oil, the liquid level should not exceed 30mm from the top plate of the oil tank to ensure the lubrication and cooling of the bearings in the pump. When the volume of the working chamber of the jack is too large, another oil tank should be set to ensure that the minimum height of liquid level after the oil is discharged is not less than 100mm so as to avoid empty suction. After the first 500h operation of the speed-regulating hydraulic water ring vacuum pump, oil should be changed and oil filter should be cleaned. Test the oil by visual and analytical methods, and change the oil i

When installing the 2BV water ring vacuum pump, we usually need to install the steam trap for auxiliary use. What should we pay attention to when using it? 1, water ring vacuum pump trap should be installed according to the drawing. 2. When the installation position needs to be changed, it shall be noted that the connection line of the pump and separation shall not be too long, or the steam and water flowing together along the pipe will increase the outlet resistance, reduce the vacuum and increase the power consumption. 3, where the connection line should be used sealed gasket, ensure not to leak. 4. Water ring vacuum pump water supply pipeline and packing supply line can be connected together. During the installation of steam trap in 2BV water ring vacuum pump, it is also necessary to pay attention to the quality of installation and the safety of use. With many years of production history, good management experience, stable product quality, vacuum production equipm

Vacuum pump in the work, the air will continue to discharge the pump body, in order to form a working requirements of the vacuum, that is to say, exhaust pressure is also affecting the water ring vacuum pump operating efficiency of another major factor. Exhaust pressure will have a great influence on the suction capacity of vacuum pump and the power consumption of shaft operation. When the vacuum pump system is in operation, if the exhaust pressure is larger, the suction capacity of the vacuum pump will be smaller, and the power consumption of the corresponding shaft operation will be larger. On the contrary, when the exhaust pressure of the system is smaller, the suction capacity of the vacuum pump will be larger, and the power consumption of the corresponding shaft operation will be smaller. Should, therefore, in the process of actual operation maintenance, real-time observation of vacuum pump exhaust pressure data in the system, when the abnormal exhaust pressure da

The oil-free vacuum pump under its working pressure should be able to discharge all the gas produced in the process of vacuum equipment. Requirements for oil contamination of vacuum equipment. If the equipment strictly requires no oil, should choose a variety of no oil pump, such as: water ring pump, molecular sieve adsorption pump, sputtering ion pump, cryogenic pump. If the requirements are not strict, can choose a pump, plus some anti-oil pollution measures, such as cold trap, baffle, oil trap, can also meet the requirements of clean vacuum. The working pressure of the oil-free vacuum pump should meet the requirements of the ultimate vacuum and working pressure of the vacuum equipment. For example, a vacuum drying process requires a working vacuum of 10mmHg, and the selected vacuum pump should have a limit vacuum of at least 2mmHg, preferably up to 1mmHg. Usually choose the limit vacuum of the pump is higher than vacuum equipment operating vacuum degree half to an or

Automatic water absorption, first to have the power to help the water absorption tool to achieve this process, for the water ring vacuum pump, we can also use the following methods to achieve its automatic water absorption: 1, water ring vacuum pump water storage can be placed near the pump, and make the bottom of the barrel slightly higher than the pump outlet; Or when a pool is built on the side near the pump room, the pool is lowered slightly to form a reservoir. Connect the bucket with the water filling hole in the pump body with a pipe. Before stopping the machine, fill the bucket with the water from the outlet pipe, and then automatically absorb water when starting next time. 2. Remove the muffler of the small engine and install a special waste drinking water device by using the exhaust gas of the engine to extract the air, so that the water ring vacuum pump can generate a certain vacuum degree. Operation, first start the engine, and then water waste water device h

Water ring vacuum pump automatic water absorption process, the first need to have suction power, to help the water absorption tool to achieve this process, for water ring vacuum pump, we can also use some methods to achieve this process: 1, water ring vacuum pump water storage can be placed nearby, and make the bottom of the bucket slightly higher than the water ring vacuum pump outlet; Or when a pool is built on one side of the water-ring vacuum pump room, the bottom of the pool is lowered slightly to form a reservoir. Connect the bucket (or pool) to the pump body filling hole with a hose. Before shutdown, use the water from the outlet pipe to fill the bucket for standby use. When starting the water ring vacuum pump next time, it can fill the bucket with water by itself. This method is easy to use 2. Remove the muffler of the small engine by using the engine exhaust pumping vacuum water charging method, install the special waste gas water diversion device, and use the
