I am able to pull a vacuum on my system, but when I blank-off, the micron gauge rises rapidly.
I am able to pull a vacuum on my system, but when I blank-off, the micron gauge rises rapidly. Unless you are using JB`s DV-29, copper tubing, or flexible metal hoses, it is not recommended to use your existing manifold and hoses for blanking-off a system to check for leaks. Hoses work very well under […]
I have been pulling a vacuum on my system using a micron gauge and cannot get it down to a low reading.
I have been pulling a vacuum on my system using a micron gauge and cannot get it down to a low reading.https See FAQ #1. Another possibility is that some oil may have entered the micron gauge and is giving false readings. The remedy is to pour regular rubbing alcohol into the connector on the […]
I have been using my low side gauge to pull a vacuum, is this wrong?
I have been using my low side gauge to pull a vacuum, is this wrong? YES. The low side gauge knows only atmospheric pressure and cannot sense moisture or non-condensables. A micron gauge is a heat sensing device that not only reads atmospheric pressure, but also measures the gases created by the vacuum pump as […]
My vacuum pump runs, but I cannot get a vacuum.
My vacuum pump runs, but I cannot get a vacuum. The coupler between the shaft of the pump and the shaft of the motor is either broken or slipping. Make sure the set screws are tight on the flats of the two shafts.
Oil changing and dust removal – the essentials of vacuum pump care
Oil changing and dust removal – the essentials of vacuum pump care While there are dry running vacuum pumps that do not require any oil, composites industry vacuum pumps are typically of the oil flooded rotary vane type. The reason the composites industry uses oil flooded pumps is because affordable oil-free vacuum pumps are usually […]
How to select lab vacuum pumps
How to select lab vacuum pumps When selecting a vacuum pump for lyophilization, evaporation or concentration applications, a vital consideration in pump performance is vapor tolerance. These applications tend to involve high vapor flows that make extra demands of the pumping capacity, so a pump that is designed to handle those vapors is important to […]
اثرات منفی فیلتراسیون خط مکش بر پمپ وکیوم
اثرات منفی فیلتراسیون خط مکش برندان کیسی عملکرد فیلترها در سیستم هیدرولیک حفظ پاکیزگی مایعات است. با توجه به اینکه هدف از حفظ پاکیزگی مایعات ، بدست آوردن حداکثر عمر مفید از اجزای سیستم است ، ضروری است که درک کنیم برخی از مکانهای فیلتر می توانند نتیجه عکس داشته باشند ، خط مکش از […]
The Negative Effects of pump Suction Line Filtration
The Negative Effects of Suction Line Filtration The function of filters in a hydraulic system is to maintain fluid cleanliness. Given that the objective of maintaining fluid cleanliness is to gain maximum service life from the system components, it is imperative to understand that some filter locations can have the opposite effect, the suction line […]
ایجاد خلا (وکیوم) خیلی بالا
ایجاد خلا (وکیوم) خیلی بالا تمیز توربو پمپ ها برای تولید خلا clean تمیز در محدوده 10-3 تا 10-10 hPa مناسب هستند. به لطف نسبت فشرده سازی بالا ، آنها با اطمینان روغن را از ناحیه ورودی پمپ های روغن دار و دور از گیرنده نگه می دارند. مدل هایی با محفظه های استیل ضد […]
13 عامل مشترکی که بر عمر پمپ وکیوم تأثیر می گذارد
13 عامل مشترکی که بر عمر پمپ تأثیر می گذارد بیش از 45 سال پمپ به مدت طولانی طراحی شده است و کاربر پمپ را به گونه ای کار کرده و نگهداری می کند که منجر به نیم قرن کار بدون مشکل شود. در معادله کلی طول عمر قابل اعتماد پمپ ، تقریباً هر عاملی […]
