1. The discharge pressure of high-pressure reciprocating pump has nothing to do with structure size and speed. The discharge pressure depends only on the power, strength and sealing function of the pump itself. The flow rate of motor reciprocating pump has nothing to do with the discharge pressure, but when the pressure is high, the flow rate of the pump will change slightly due to the gas dissolved in the liquid and the leakage of valve and packing. Therefore, the reciprocating pump can not adjust the flow by closing the outlet valve. When the discharge valve is closed, the fluctuation of discharge pressure will lead to motor overload or pump damage.

Quality of Roots vacuum pump The practical production of Roots vacuum pump is carried out through various processes. In order to strengthen the quality of the blank, the deep processing should be carried out strictly. The management system should be done in time to help the production of waste products. Under the condition of not affecting the order production, the waste parts should be treated well, and the man hour quota should be controlled well On the basis of the bottom operation, we should timely corresponding to the needs of the market, and strengthen the optimization of the processing technology of the products.The use of Roots vacuum pump strength has become an important condition to promote the development of enterprise productivity. Its use in different occupations has different application ability, but the same point is that it can not be used as a single pump, it can only be assembled with other equipment into unit products for use, playing a driving strength foundation. Through the use function of the equipment itself, it can be useful For the use of other equipment to achieve a higher functional strength, improve the driving effect of product application.Under the premise of accelerating the development of Roots vacuum pump's useful effect, it is necessary to make continuous performance of product application and function, further enhance the improvement of its product superiority, let the application of its products drive the development of enterprise's productivity, promote the continuous improvement of its application function in all aspects, fully accelerate the driving of its product application ability, and make it continuously perform on the basis of rational use Show the outstanding performance of the product application effect, and then show the usable function of the equipment.In order to improve the quality of Roots vacuum pump, it is necessary to combine the status of product application, improve the development of all application strength, and constantly complete the overall driving of product application ability, so that it can enhance the continuous improvement of its quality advantage under the advantage effect of reasonable use, and make it show internal use advantage in the development process.Industrial craneRoots BlowersRoots Vacuum Pump

The noise of plunger pump is analyzed and divided into human factors and non-human factors. Taking CY14-1B axial piston pump as an example, the working principle is analyzed first, and then the factors causing noise are found out. Finally, some targeted measures are proposed to reduce noise.Status and classification of hydraulic pumpsMechanical transmission, electrical transmission, hydraulic transmission and pneumatic transmission are commonly used in industry at present. Hydraulic transmission is widely used in all kinds of construction machinery because of its high working pressure, transmission power and the weight of the actuator is relatively large, can be continuously variable and so on. And hydraulic transmission in a very important energy conversion element - hydraulic pump, is widely used.Hydraulic pump, as the power unit in the hydraulic system, plays a vital role in the hydraulic system. According to the type can be divided into blade pump, gear pump, plunger pump, screw pump. Among them, the plunger pump is a common, but also widely used high pressure pump, the noise reduction of the plunger pump this problem, there are many scholars and experts are studying.
