Eliminate hidden dangers in hydraulic hose crimping machines and pipe press machine
The latest generation of hydraulic hose crimping machine and hydraulic hose press machine produced by HengHua replaces and replaces the important devices in hydraulic hose crimping machine and hydraulic hose press machine. The gear pump is upgraded to the plunger pump. The plunger pump relies on the plunger in the cylinder. The reciprocating movement in the body changes the volume of the sealed working volume to realize oil absorption and oil pressure, which has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment.
The following HengHua crimping machine will talk about how to maintain and maintain the plunger pump, improve the working efficiency of hydraulic hose crimping machine, hydraulic hose press machine, increase the service life, and eliminate the hidden hazards in crimping machines and pipe presses.
The selection of anti-wear hydraulic oil in hydraulic hose crimping machine and hydraulic hose press machine has a great impact on the working efficiency and service life of the equipment. It can be said that it is an invisible hazard in hydraulic hose crimping machine and hydraulic hose press machine. Hydraulic is developed from rust-proof and anti-oxidation hydraulic oil.It has a series of products such as alkaline high zinc, alkaline low zinc, neutral high zinc type and ashless type.They all have a kinematic viscosity according to 40'C. Divided into four grades of 22, 32, 46, 68. Hydraulic hose crimping machine and hydraulic hose press machine use 46 anti-wear hydraulic oil.
Good anti-wear hydraulic oil standard:
(1),suitable viscosity and good viscosity-temperature performance to ensure that the hydraulic components are well lubricated, cooled and sealed under the conditions where the working pressure and working temperature change.
(2) Good extreme pressure abrasion resistance to ensure that the friction pairs in oil pumps, hydraulic motors, control valves and oil cylinders are properly lubricated under high pressure and high speed and harsh conditions to reduce wear.
(3) Excellent oxidation stability, hydrolytic stability and thermal stability to resist the influence or effect of air, moisture, high temperature, high pressure and other factors, making it less prone to aging and deterioration and prolonging the service life.
(4) Good foam resistance and air release value to ensure that the foam generated under the condition of mechanically vigorous stirring during operation can quickly disappear; and the air mixed with oil can be released in a short time to Achieve accurate, sensitive and smooth transmission of static pressure.
(5).Good anti-emulsification, can be quickly separated from the water mixed in the oil, so as not to form an emulsion, which will cause the metal material of the hydraulic system to rust and reduce the performance.
(6) good rust prevention to prevent metal surface from rusting.
