How to solve the screw vacuum pump compression shortage


Screw vacuum pump in use, sometimes there will be insufficient compression, hangzhou xinanjiang industrial pump to solve the problem of insufficient compression of screw vacuum pump:
1, in the screw vacuum pump, the auxiliary exhaust valve is a special structure, the general use of rubber ball valve, its role is to solve the screw vacuum pump in the process of running the phenomenon of over compression and insufficient compression. The two phenomena can cause excessive power consumption, because there is no direct water ring vacuum pump exhaust valve, and exhaust pressure is always fixed, water ring vacuum pump compression ratio't decided to port of termination of the starting position of the location and vent, the two position fixed, so don't meet the needs of the suction pressure changes
2, in order to solve the problem of screw vacuum pump, generally set rubber ball valve at the bottom of the exhaust port, so that when the screw vacuum pump pump chamber reached exhaust pressure prematurely, the ball valve automatically opened, gas discharge, to solve the over-compression phenomenon. In general, when designing water ring vacuum pump, zui low suction pressure is used to determine the compression ratio, so as to determine the initial position of the exhaust port, which solves the problem of insufficient compression
3, screw vacuum pump and the outlet of small cavity volume further decrease the pressure rise further, when the pressure is greater than the exhaust pressure of the gas, the compressed air to escape from the vent is in continuous operation process of the screw vacuum pump, continuously carrying on the suction, compression, exhaust process, so as to achieve the purpose of continuous extraction

Reasons and Solutions for Fragile Belt of Roots Blower

图片
1. Reasons for easily broken belt of Roots blower: 1. First of all, consider the high speed and high temperature of Roots blower. 2. The distance between the head and motor of Roots blower is too large and the belt is tight. 3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing. 4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear. 5. Heavy load, long-term overload operation of belt is easy to break. 6. Roots fan nose and motor pulley are not concentric, different axes. 7. Belt quality problems. 2. Measures to prevent the belt of Roots blower from breaking. 1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking. 2. The pulley between the motor and the fan should be parallel, which is a key point. If not para
