Reasons why the vacuum of rotary vane vacuum pump is not high and its solution
Many customers in the use of rotary vane vacuum pump will encounter when the problem is not high vacuum, then what is the reason? How to solve the rotary vacuum pump is not high vacuum problem? Zhejiang vacuum pump factory has the following twelve points for your reference. (1) If the pump cooling water is not enough, should open or increase the cooling water. D, such as improper assembly, resulting in single-sided wear, check and then reload.
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.

(2) rotary vane vacuum pump to use a long time, wear large gap increases, the damaged parts should be repaired or replaced.
(3) pump temperature is too high:
(4) oil level is too low to sight oil line position, should add enough oil.
(5) gas valve is not closed Yan leak, should be closed.
(6) bad oil, replace the new oil.
(7) the front end of the oil seal in the seal ring damaged or rubber deterioration, should be replaced.
(8) turn the spring break, it should be removed and replaced.
(9) Valve piece damaged, should be replaced.
(10) rotary vane vacuum pump leakage of the atmosphere is mostly due to the poor seal of the pump side, then open the exhaust cover, check the oil pool B is lack of oil, such as oil should be refuel from the hole at the oil pool B Filled with oil.
(11) If the gas being drawn high temperature, the gas should be cooled before entering the rotary vane vacuum pump. B, such as inhalation of hard objects cylinder wear, repair should be replaced.
(12) intake filter blockage, remove the cleaning.
