main features 

1. The shell is made of cast aluminum alloy, with light weight and beautiful appearance;

2. The motor is of non oil invasion structure, with class B or class F insulation (according to user requirements), good heat resistance and long service life;

3. The motor junction box is equipped with a seal and adopts cable stuffing box for incoming wire, which is firm and reliable, and the protection grade of the electrical enclosure reaches IP55;

4. The motor shaft and push rod have special surface treatment, so that the service life of the seal is greatly extended;

5. The cylinder shell is equipped with a balance air chamber on one side, so that the thruster can be installed at 0-180 ° in any direction, so as to expand its scope of use;

6. All seals and bearings are world famous products with reliable sealing and long service life;

7. The fasteners are made of stainless steel, beautiful and durable.

Additional devices

1. Upper limit switch: it can indicate whether the brake is open, whether the push rod is pushed to the specified position and other information;

2. Lower limit switch: it can indicate whether the brake is closed correctly, whether the push rod returns to the specified position, and can set the upper and lower limit switches at the same time;

3. Add a built-in spring (only a short stroke thruster can be used), and the spring force can be determined by the user, but shall not exceed the built-in spring force (see the parameter table);

4. Add heater: when the ambient temperature at the place of use is lower than -25 ℃, the user can add a heater if necessary. See attached table 1 for the heater parameters;

5. The rise delay valve and the fall delay valve can continuously extend the rise or fall time. The delay range is from the rated action time to 30 seconds. The specific delay value can be set according to user requirements. The push rod connecting blocks of all thrusters can be rotated. Ed50-ed301 fixed seat can rotate 90 °, and ed23-ed30 fixed seat can also rotate 90 °, but the installation height dimension a is increased by 8mm; Standard Huawei ed thruster

No matter what installation position, the piston rod cannot bear any force, so as not to affect the service effect and life.

Question:

[single choice] the push rod of electric hydraulic thruster rises slowly, () is not the reason.

A Insufficient oil

B Main spring too tight

C Improper use of low temperature oil

D As a very important safety control device, low voltage brake is widely used in lifting, metallurgy, mines, ports The main products in construction and other machinery are: electric hydraulic block brake series ywzb ywz3b ywz4b ywz5 ywz8 ywz9 ywz12 ywz13 YW YWL tywz2 YWP electromagnetic block brake JZ (tj2a) MW (z) zwza zwz2 zwz3a dcw3 electromagnetic fail safe disc brake 5SE 561se 56se dcpz12.7 4se 3Se st1se st2se 450SE hydraulic fail safe disc brake 5sh 4sh 3SH 450sh st1sh st3sh st4sh sb(yqp) Sbdst5sh st10sh st16sh st25sh st25sh-a st40sh 904sh SBB electric hydraulic arm disc brake ypz2 Ⅰ, Ⅱ, Ⅲ ypz2 Ⅳ, Ⅴ, Ⅵ pneumatic caliper disc brake qp12.7 5SP 4SP 3sp 450sp PD adp60m-adp61m-adp62m hydraulic direct acting disc brake dadh75 adh60 adh90 adh120 dadh80 dadh90 dadh103 dadh195 electric hydraulic thruster YT1 ed explosion proof electric hydraulic thruster byt1 bed
