Taber muiti-finger scratch tester Taber muiti-finger scratch tester - Model 710(multi-finger scratch/mar tester 710) is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage not classified as ordinary wear. Based on the apparatus described in popular automotive specifications, the instrument is commonly referred to as a five-finger (five-arm) scratch & mar tester and most often used to evaluate plastics. Standards Ford BN 108-13 ： Resistance to Scratching General Motors DMN3943 Danmler-Chrysler LP-463DD-18-01：Automotive standards Features 1. Precision instrument measures damage to surfaces not classified as ordinary wear. Using precision tips, the Taber Multi-Finger Scratch/Mar Tester is used to measure the susceptibility of material surfaces to scratching, marring, gouging, and other similar physical damage not classified as ordinary wear. 2. Design based on five-finger scratching device described in automotive specifications Specimens are secured to a pneumatically driven platform. Five independent spline-shaft fingers with varying weights exert a constant, vertical load on the test specimen as it travels under interchangeable scratch tips. Spline-shaft fingers are mounted on a rigid gantry platform. Support rests allow the operator to secure individual shafts in a rest position, permitting the testing of nonstandard width samples. 3. Test a wide range of products. The ‘five-finger’ scratch tester has been popular in the automotive industry for testing smooth or grained plastics commonly used in ornamentation or trim. Useful for quality control as well as material or product development, the Multi-Finger Scratch / Mar Tester is ideal for evaluating plastics, rigid organic materials, paints and coatings, soft metals, linoleum, plus many others.

Understanding What VoIP Means VoIP — which stands for voice over Internet protocol and often pronounced “voyp” — is a new technology that will improve the way we communicate. VoIP basically means voice transmitted over a digital network. The Internet, however, isn’t strictly necessary for VoIP. What is necessary for VoIP technology is the use of the same protocols that the Internet uses. (A protocol is a set of rules used to allow orderly communication.) Thus, voice over Internet protocol means voice that travels by way of the same protocols used on the Internet. VoIP is often referred to as IP telephony (IPT) because it uses Internet protocols to make possible enhanced voice communications. The Internet protocols are the basis of IP networking, which supports corporate, private, public, cable, and even wireless networks. VoIP unites an organization’s many locations — including mobile workers — into a single converged communications network and provides an unparalleled range of telephony support services and features .

Influence of cooling system temperature on the performance of vacuum pump unit In summer, the temperature of closed water can reach 35 ℃. Therefore, it is difficult to guarantee the supercooling degree of 4.2 ℃ in the actual operation of vacuum pump. As the sealing water temperature approaches to saturation, its pumping capacity also decreases, until saturated vaporization and loss of working capacity.The working pressure of the vacuum pump and the pressure of the condenser is a dynamic balance process. No matter how high or low the circulating water temperature is, the suction pressure of the vacuum pump must be lower than that of the condenser in order to pump the non condensable gas from the condenser. Therefore, the sealing water temperature of vacuum pump must be lower than the saturation temperature corresponding to the exhaust pressure.The situation of vacuum drop is that the sealing water in the vacuum pump is vaporized because the water in the gas water separator is not changed in time. A few days later, the test was carried out on vacuum pump a of No.2 unit. After adding 16 ℃ cold water into pump a, the temperature of separator was 16.2 ℃. After starting pump a, the temperature rose to 24.5 ℃. With the increase of temperature, the vacuum decreased. When the water temperature was 30 ℃, the vacuum increased about 1kPa and the current of vacuum pump increased about 0.85a. When the working water temperature drops by 1 ℃, the vacuum increases by about 0.19kpa. It can be seen from the test that it is an important means to ensure the vacuum of the vacuum unit to ensure the lower temperature of the sealing water of the vacuum pump in summer.CL Sereis Cone Liquid Ring Vacuum PumpRoots BlowersRoots Vacuum Pump

Plunger pump is an important equipment of hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder to burst and change the volume of the sealed working chamber to complete oil absorption and pressurization. Plunger pumps have the advantages of high rated pressure, compact structure, high efficiency, and easy flow adjustment. They are widely used in hydraulic presses, construction machinery, ships and other occasions with high pressure, large flow, and large flow requirements.The important part of the plunger pump is the bearing. Assuming that the bearings have clearances, the normal clearances of the three pairs of friction pairs in the hydraulic pump cannot be guaranteed, and the oil film thickness of the hydrostatic bearing of each friction pair will also be damaged, thereby reducing the service life of the piston pump bearings. According to the data provided by the hydraulic pump manufacturer, the average service life of the bearing is 10,000 hours. If this value is exceeded, it is necessary to replace with a new port. Without professional testing equipment, it is impossible to detect the clearance of the disassembled bearing, only visual inspection can be performed. If scratches or discoloration are found on the surface of the roller, it must be replaced. When replacing the bearings, the plunger pump manufacturer asked us to pay attention to the English letters and model numbers of the original bearings. Most of the plunger pump bearings use large load capacity bearings, so it is good to buy products from original manufacturers and original specifications. If we change to another brand, we should consult a person with bearing experience to check the table and change the table, so as to maintain the bearing's accuracy grade and carrying capacity.The service life of a plunger pump is related to normal maintenance, the quantity and quality of hydraulic oil, and the cleanliness of the oil. This is also an effective way to prolong the service life of the plunger pump and avoid the wear caused by particles in the oil. When replacing parts during maintenance, use as many original parts as possible. These parts are sometimes more expensive than other imitation parts, but their quality and stability are better. Assuming the purchase of cheap imitation parts, it seems to save costs in the short term, but this also brings hidden dangers, which may cause greater harm to the use of plunger pumps.Related products: Vacuum Brazing Machine For PCD Diamond ToolsOther related products:Liquid Ring Vacuum Pump
