Troubleshooting of rotary vane vacuum pump 2013-03-05 15:01:02
Troubleshooting methods for rotary vane vacuum pumps: Rotary vane vacuum pumps in operation, if they are not properly operated, will often fail, such as the vacuum of the rotary vane vacuum pumps, such as reduced vacuum, oil injection, smoke, oil leakage at the oil seal, noise, etc., and the emulsification of the vacuum pump oil in the pump. . In case of such a situation, don't panic at first, wait for the shutdown to eliminate one by one according to the fault. Here are a few troubleshooting methods. 1. Rotary vane vacuum pump smoke and oil injection: refers to the smoke or oil injection from the exhaust port of the rotary vane vacuum pump during operation. 1. Smoke. If the pump has just started to run, it is normal. If it smokes for a long time, it is abnormal. Solution: Smoke indicates that outside the air inlet of the pump, including pipes, valves, and containers are repaired. After the leak detection is processed, the smoke will end. Vortex Flowmeter 2. Fuel injection indicates that there are a large number of leaks outside the air inlet, and even the air inlet is exposed to the atmosphere. Solution: Seal the air inlet of the pump and make the pump run. If no oil is injected, it means there is a leak; if the exhaust valve plate is damaged, check whether the exhaust valve plate is damaged, and replace the bad exhaust valve plate. 2. Noise of rotary vane vacuum pump: here refers to the noise of the pump. 1. Knocking on the cylinder, the pump makes irregular noises when it is running, like the sound of metal beating metal. This is the sound made by the rotary vane hitting the pump body. This situation is mainly caused by the spring break between the paired rotating pieces, contraction or ejection failure. Solution: Turn on the pump and check if the rotary vane spring is damaged. Replace the spring. 2. The noise of the exhaust valve plate is mainly caused by the damage of the exhaust valve plate of the pump. The solution: replace a good exhaust valve piece. 3. The vacuum degree of the rotary vane vacuum pump decreases: the measured vacuum degree of the rotary vane vacuum pump is lower than the factory index or the vacuum degree of the previous use. There are many reasons for low vacuum, here are several main situations. 1. The brand of the rotary vane vacuum pump oil added this time is different from the original one. Different vacuum pump oil grades have different results due to the different saturated vapor pressures in the oil of different grades. The solution: replace the correct new vacuum pump oil according to the product model specification. 2. In addition, the low vacuum caused by the vacuum pump oil is the emulsification and discoloration of the vacuum pump oil, or it is too dirty. Solution: Drain all the vacuum pump oil in the pump, replace the same type of vacuum pump oil, and solve the problem that water vapor and impurities in the pumped gas do not enter the pump. 3. The temperature of the pumped gas may be too high. The solution: reduce the temperature of the pumped gas, or add a corresponding heat exchanger. 4. The oil circuit in the pump is blocked or not smooth, and a certain amount of oil is not maintained in the pump cavity. Solution: Check whether the oil circuit is unblocked, and add the same type of vacuum pump oil. 5. Increase the clearance of coordination. This is because the long-term pumped air contains dust, etc., which causes the gap between the rotor and the stator to increase after wear. Solution: Check whether the gap is too large and replace with new parts.
Water ring vacuum pump performance 2013-03-05 15:00:06
Water ring vacuum pump performance Shanghai Shenyi Water Pump Manufacturing Co., Ltd. specializes in the production of various types of water pumps and has a high-quality modern technology team. It is a modern enterprise integrating production, scientific research and sales. The company has a long production history, advanced equipment, and strict testing. It has offices in more than 20 major cities across the country. Its annual sales volume reaches 30,000 sets. The products are also exported to Southeast Asian countries, West Asia and Iran. The water ring vacuum pump is used to suck air and other non-corrosive, water-insoluble, and non-solid particles, so as to form a vacuum in a closed container. A small amount of liquid is allowed to be mixed in the suction gas, which is suitable for pumping gas and water vapor. The suction pressure reaches 33Mbar absolute pressure (97% vacuum). When the vacuum pump works for a long time under the suction pressure lower than 80mbar, it should be connected The cavitation protection tube protects the pump. If equipped with an atmospheric ejector, the suction pressure can reach 10Mbar. The ejector can be directly installed on the vacuum pump. The price is favorable and the quotation is reasonable. It is an ideal choice for your vacuum pump. SZB water ring vacuum pumps cannot be used to pump gases with excessive oxygen content, toxic or chemical interaction with the pump oil. The pump and coaxial direct connection design saves space and is easy to install. The mechanical seal is used as the standard configuration to eliminate leakage, easy maintenance, stable operation, and noise can be as low as 62 decibels. The uniform corrosion resistance design, the bronze impeller improves the corrosion resistance of the pump, and the stainless steel material is more suitable for more demanding applications. The unique flexible exhaust port design does not produce over-compression, ensuring the efficiency of the SZB vacuum pump within its performance range. The SZB water ring vacuum pump can start pumping directly from atmospheric pressure. It is widely used in electronic device manufacturing, vacuum drying, filtration, dipping, wax coating, welding, smelting, chemical industry, light industry, petroleum, medical, pharmaceutical, printing and dyeing, semiconductor, food, atomic energy, textile and other scientific research institutions, colleges and universities, Industrial and mining enterprises.
